Pass - `GraphOptions.SupportsSubgraphs` in the attribute when subgraphs are wanted. -2. **Node classes.** `[Serializable] class MyNode : Node`. Override `OnDefinePorts` and end every port - builder chain with `.Build()`. Override `OnDefineOptions` for inspector-editable settings, and read - them inside `OnDefinePorts` with `GetNodeOptionByName(name).TryGetValue(out var v)` when ports - depend on them. Call `.Delayed()` on count-like options so ports are not rebuilt on every keystroke. - Use `[Node("Category/Path", iconPath, title, stylesheet)]` for placement, icon, default title and USS. -3. **Validation.** Override `OnGraphChanged(GraphLogger logger)` and report with - `logger.LogError`, `LogWarning` or `Log`, passing the offending node or port as context so the - marker appears on it. Never mutate the graph in this callback; put the fix in a `GraphLogAction` - attached to the message, a menu item, or the importer. -4. **Structure, as requested.** Context and block nodes, subgraphs, blackboard variables, type casting - through `IsConnectionAllowed`, a toolbar element, or a context menu. Details in `graph-api.md`. -5. **Output.** A `ScriptedImporter` registered on the same extension compiles the graph into a plain - runtime asset. The shape is always the same: - - ```csharp - var graph = GraphDatabase.LoadGraphForImporter(ctx.assetPath); // never LoadGraph here - if (graph == null) return; // bad path or type: log and stop - var start = graph.GetNodes().OfType().FirstOrDefault(); - if (start == null) return; // OnGraphChanged already reported it - var next = start.GetOutputPortByName("Next").FirstConnectedPort?.GetNode(); // null when unconnected - var titlePort = next.GetInputPortByName("Title"); - titlePort.TryGetValue(out var title); // the value typed on the node - if (titlePort.IsConnected) { /* resolve titlePort.FirstConnectedPort.GetNode() upstream instead */ } - ctx.AddObjectToAsset("Runtime", runtime); ctx.SetMainObject(runtime); - ``` - - The runtime asset and its assembly must not reference `Unity.GraphToolkit.Editor`; keep `Hash128` - IDs as `Hash128`.

States have no ports; the state machine owns the - transitions. Options declared in `OnDefineOptions` appear only in the Graph Inspector. -3. **Conditions.** `[Serializable] [Condition("Health")] class HealthCondition : Condition` with - `protected override bool DisplayComparisonDropdown => true` when a comparison operator is wanted. - Derive from `Condition` directly for a valueless trigger. Group (And/Or) and variable conditions are - built in; do not reimplement them. -4. **Optional.** Custom self transitions (`SelfTransition` + `[Transition(...)]`), custom UI through - `StateView` and `ConditionView`, and `[StateMachineMenu]` / `[ConditionMenu]` entries. -5. **Validation.** Override `OnStateMachineChanged(StateMachineLogger logger)`. Same rules as - `OnGraphChanged`. -6. **Output.** A `ScriptedImporter` loads with `StateMachineDatabase.LoadStateMachineForImporter`, - then walks `GetStates()`, each state's `GetOutgoingTransitions()`, each transition's `GetRules()`, - and each rule's `RootCondition` tree. That tree always contains the built-in kinds as well as the - user's classes, so the compiler must handle `IGroupCondition` (recurse, honour `Operation`) and - `IVariableCondition` (`Variable.Name`, `Comparison`, `Value`) before matching custom `Condition` - types. - -## Editing a graph from code - -When a menu item, generator or tool builds or edits an asset, bracket the mutations: -`LoadGraph`/`CreateGraph` → `UndoBeginRecordGraph("Action")` → `AddNode`, `Connect`, -`port.TrySetValue`, `CreateVariable` → `GraphDatabase.SaveGraph(graph)` → `UndoEndRecordGraph()`. -The state machine equivalents are `UndoBeginRecordStateMachine`, `Connect(fromState, toState)`, -`SaveStateMachine` and `UndoEndRecordStateMachine`.

Add `.WithConnectorUI(PortConnectorUI.Arrowhead)` for a flow look | Flow ports carry no value; typing them invites wrong connections | -| Hide a node type from the Add menu | Make it `abstract`, or move it to another assembly without `[UseWithGraph]`, or set `GraphOptions.DisableAutoInclusionOfNodesFromGraphAssembly` and opt nodes in explicitly | Every concrete node class in the graph's assembly is listed automatically | -| Group nodes in the Add menu | `[Node("Category/Sub")]`. The class or title name is appended after the path | The attribute's first argument is a folder path, not the node's title | -| Know what changed, like the old `graphViewChanged` | 6000.7+: `OnGraphChanged` and `logger.GraphChanges.ChangedNodes` with `ChangeKinds` flags for added and modified nodes.

On 6000.6, explain it is not available | The State Machine API does not exist before 6000.7 | -| Extra UI inside a node | `NodeView` on 6000.7+.

Paths are relative to this skill's folder. + +- **Importer to a runtime asset, and wiring the debug view from runtime code:** [`references/runtime-and-visualization.md`](references/runtime-and-visualization.md). + The importer always has this shape: + + ```csharp + var graph = GraphDatabase.LoadGraphForImporter(ctx.assetPath); // never LoadGraph here + if (graph == null) return; // bad path or type: log and stop + var start = graph.GetNodes().OfType().FirstOrDefault(); + if (start == null) return; // OnGraphChanged already reported it + var next = start.GetOutputPortByName("Next").FirstConnectedPort?.GetNode(); // null when unconnected + var titlePort = next.GetInputPortByName("Title"); + titlePort.TryGetValue(out var title); // the value typed on the node + if (titlePort.IsConnected) { /* resolve titlePort.FirstConnectedPort.GetNode() upstream instead */ } + ctx.AddObjectToAsset("Runtime", runtime); ctx.SetMainObject(runtime); + ``` + + The runtime asset keeps `Hash128` IDs as `Hash128` and never references `Unity.GraphToolkit.Editor`. +- **State machines (6000.7+):** [`references/state-machine-api.md`](references/state-machine-api.md).

Package APIs are versioned by package version and Engine APIs by Unity version, so check both before relying on a specific class or method, because APIs are frequently marked obsolete between versions. + +1. Use the `unity-cli` skill to check the project's Unity version and installed package versions. +2. For package APIs, fetch and cache `https://docs.unity3d.com/Packages/<package-name>@<version>/xrefmap.yml` (eg `com.unity.2d.tilemap.extras@6.0`). It maps each public member's fully qualified name to its docs page `href` (eg `href: api/UnityEngine.RuleTile.TilingRule.html` => `https://docs.unity3d.com/Packages/com.unity.2d.tilemap.extras@6.0/api/UnityEngine.RuleTile.TilingRule.html`). Grep it locally instead of refetching per lookup; don't read the whole file. Start with `GridPaletteUtility.CreateNewPalette`, `RuleTile.TilingRule` (`m_Neighbors`, `m_NeighborPositions`, `m_RuleTransform`) and `RuleTile.TilingRuleOutput.Neighbor` (`This`, `NotThis`). +3. For Engine APIs, if the Editor install folder has a `Data/Documentation` folder, grep the html files in its `en/ScriptReference` folder and skip the rest of this step. Otherwise fetch and cache `https://docs.unity3d.com/<VERSION>/Documentation/ScriptReference/xrefmap.yml` (about 6 MB, so grep it, don't read it) and convert the `uid` to a markdown page: remove the parameters in brackets, lowercase it, replace `.` with `/`, add `.md`, and fetch `https://docs.unity.com/en-us/engine/<VERSION>/script-reference/<converted uid>`. For example, `UnityEditor.AssetDatabase.LoadAllAssetsAtPath(System.String)` => `https://docs.unity.com/en-us/engine/6000.3/script-reference/unityeditor/assetdatabase/loadallassetsatpath.md`. If that page doesn't exist, use the entry's `href` under `https://docs.unity3d.com/<VERSION>/Documentation/ScriptReference/`. + +## Glossary + +The reference files write RuleTile rules as 3x3 text grids, read from the top row to the bottom row: + +| Symbol | Meaning | In the API | In the Rule Tile Inspector | +|--------|---------|------------|----------------------------| +| `.` | The neighbour must be this RuleTile | `RuleTile.TilingRuleOutput.Neighbor.This` | Green arrow | +| `X` | Any neighbour (don't care) | Position left out of `m_Neighbors` and `m_NeighborPositions` | Empty cell | +| `*` | The tile itself | Not stored | Centre cell | + +Don't read `X` as `NotThis`, because the Inspector draws `NotThis` as a red X, which means the opposite: the neighbour must not be this RuleTile. + +## Workflow Pick the matching reference doc based on what the user wants, then follow it: - **Tile Palette** — [references/palette-create.md](references/palette-create.md) — when the user wants to organize tiles for 2D level design or create a new rectangular, hexagonal, isometric, or isometric Z as Y grid layout. - **Blank/empty RuleTile** (no sprites provided) — [references/ruletile-createempty.md](references/ruletile-createempty.md) — when the user wants a blank RuleTile (rectangular grid), HexagonalRuleTile, or IsometricRuleTile for custom rule configuration and has not provided or referenced any sprites. - **RuleTile built from existing sprites** (sprites, terrain art, edge tiles provided) — [references/ruletile-createfromsegment.md](references/ruletile-createfromsegment.md) — when the user wants tiles that autotile as they paint, or a RuleTile built from existing terrain or edge sprites so tiles connect correctly. + +## Final step + +Do the following checks: + +1. Check the project has zero console errors. Use `console_status` for counts. +2. Read the assets back with `eval` (fully qualified), because an asset can exist without its settings having stuck: + - If you created a tile palette, check that `AssetDatabase.LoadAllAssetsAtPath` on the palette returns a `GridPalette` sub-asset, and that the `Grid` on the palette's root GameObject has the `cellLayout` and `cellSize` you chose. + - If you created a RuleTile, check that `AssetDatabase.LoadAssetAtPath` with the RuleTile type you created returns the asset, that `m_TilingRules.Count` equals the number of rules you created, and that each rule's `m_Sprites` has exactly one entry: `null` for an empty RuleTile, or the assigned sprite for one built from sprites. +3. If you built a RuleTile from sprites, check that it picks the right sprite as it's painted, because correct fields don't prove the rules match the art. Open a temporary scene with `EditorSceneManager.NewScene(NewSceneSetup.EmptyScene, NewSceneMode.Additive)`, add a Grid with a Tilemap, use `Tilemap.SetTile` to paint a 3x3 block of the RuleTile, and check that `Tilemap.GetSprite` at each cell returns the sprite of the rule that matches that cell's neighbours. For example, the centre cell gets the fully surrounded rule's sprite, if the RuleTile has that rule. Then close the scene with `EditorSceneManager.CloseScene(scene, true)` without saving it. +4. If a value doesn't match, fix the asset and repeat the check. +5. Stop there unless the user asked you to prove it works or you suspect a specific fault. If you do enter Play mode, do it once only to chase a fault you already suspect. Read the world through `eval` rather than adding logging.

The [collider interaction matrix](https://docs.unity.com/en-us/engine/<VERSION>/manual/physics-section/physics-overview/collision-section/collider-interactions/collider-types-interaction.md) lists both as sending trigger messages. +- There is no separate trigger matrix or collision matrix. People use those terms for the **Layer Collision Matrix** in the Physics settings. +- **Contact Pairs Mode** (**Edit > Project Settings > Physics**) decides whether kinematic-kinematic and kinematic-static pairs send **collision** messages (`OnCollisionEnter`). It doesn't stop trigger messages, so don't offer it as the fix for a trigger. To check it for a collision, read `m_ContactPairsMode` in `ProjectSettings/DynamicsManager.asset`, because there's no API getter, and match the value to the options on the [Physics settings](https://docs.unity.com/en-us/engine/<VERSION>/manual/unity-editor/editor-settings-reference/comp-manager-group/class-physics-manager.md) page. + +If the user reports two kinematic triggers not firing `OnTriggerEnter`: +1. State that the combination is valid and that Contact Pairs Mode doesn't affect it. +2. Direct the user to check, in this order: + - Layer Collision Matrix (Edit > Project Settings > Physics), and the **Layer Overrides** (Include Layers and Exclude Layers) on each Collider and Rigidbody, which take priority over the matrix. + - Script placement: the callback must be on the trigger GameObject or the entering object. + - Method signature: `OnTriggerEnter(Collider other)` with no `2D` suffix. + - Movement method: move kinematic Rigidbodies with `Rigidbody.MovePosition()` or `transform.position` writes. Kinematic bodies aren't moved by `Rigidbody.linearVelocity`, so a kinematic body driven by velocity never reaches the other trigger. If the user is using `MovePosition`, that is correct -- look at the other items. +3. Do NOT run `Physics.Simulate()` to verify, because Edit mode simulation doesn't send MonoBehaviour messages. +4. Do NOT fetch external documentation -- the docs agree with this skill. +5. Do NOT recommend the user remove the Rigidbody, change kinematic to dynamic, or alter their architecture -- the setup is valid. + +## Required output -- non-negotiable + +Every invocation MUST end with a user-facing answer that gives the diagnosis and fix, because tool calls alone don't help the user. + +**Hard stop**: After 5 tool calls of any kind, stop calling tools and write the most-likely diagnosis from the Fast-Paths or checklists, even if not fully confirmed. + +**No permission-asking**: Never end with "Would you like me to proceed?" or similar. If the script is in the project or an Editor is connected, apply the fix directly by editing the script, or the scene through the Editor. Otherwise, give a complete self-contained explanation. Don't ask, because asking permission costs the user another turn. + +## STOP CHECK -- match before any tool call + +Before calling any tool, scan the user's prompt against the Fast-Paths below. The **first** match is the **complete response** -- write the answer and stop. Don't search the project, read files, inspect the scene, run C# in the Editor, or fetch documentation, because these answers are already verified. + +### Fast-Path 1 -- 2D physics or DOTS + +- **2D physics** (`Rigidbody2D`, `Collider2D`, `OnCollisionEnter2D`, `Physics2D`): if the `create-2d-physics` skill is installed, use it instead, because it covers both 2D physics systems. Otherwise say this skill covers 3D physics only, and stop. +- **DOTS** (`PhysicsCollider`, `ICollisionEventsJob`, `ITriggerEventsJob`, `Unity.Physics`, Havok, ECS, Entities): if a `physics-dots` skill is installed, use it instead. Otherwise start with a one-sentence disclaimer that DOTS physics is outside this skill's scope, give a brief best-effort answer with the DOTS APIs (`PhysicsBody`, `PhysicsCollider`, `ICollisionEventsJob`, `SimulationSingleton`), and end with one documentation link. + +Don't apply 3D PhysX or MonoBehaviour rules to these questions, and don't suggest switching physics systems. + +### Fast-Path 2 -- Two kinematic triggers not firing OnTriggerEnter + +**If** both objects are kinematic AND both are triggers: apply the **CRITICAL FACT** response, starting with the layer checks. + +### Fast-Path 3 -- Ragdoll explodes on frame 1 with no applied forces + +**If** a ragdoll, jointed body, or character launches or explodes on the first frame with no applied forces: +- Cause: overlapping colliders cause a one-frame depenetration velocity spike. +- Fix: shrink the ragdoll colliders so none overlap at the starting pose. State it as the only primary fix. +- Confirm with **Window > Analysis > Physics Debugger**, which the user opens. It highlights overlapping pairs on the first frame. +- Do NOT list joint limits, joint projection, joint configuration, joint types, mass ratios, or drive parameters as causes, even when the prompt mentions them, because they don't cause this symptom. +- Do NOT recommend disabling `Enable Collision` on the joint as the primary fix, because it hides the overlap rather than removing it. + +### Fast-Path 4 -- CharacterController + OnCollisionEnter not firing + +**If** the moving object has a `CharacterController` and the user expects `OnCollisionEnter`: +- `OnCollisionEnter` never fires for movement by `CharacterController.Move()`. Use `OnControllerColliderHit(ControllerColliderHit hit)` instead. +- Do NOT suggest adding a `Rigidbody`, because a `CharacterController` and a `Rigidbody` on the same object fight over its movement. + +### Fast-Path 5 -- AddForce stopped working after object settled + +**If** `AddForce` or `AddTorque` stopped working after the object landed or stopped: +- Cause: the Rigidbody fell asleep. +- Fix: call `Rigidbody.WakeUp()` before `AddForce`. Apply the code edit directly, and don't change the Input System or other unrelated code. + +### Fast-Path 6 -- All physics frozen but raycasts still work + +**If** callbacks have stopped and forces and gravity have no effect, but `Physics.Raycast` still hits: `Time.timeScale` is `0`. Restore it to `1f`, typically in the pause menu or cutscene controller. + +### Fast-Path 7 -- Raycast origin inside the target collider + +**If** `Physics.Raycast` returns false and the ray starts inside the target: read the notes on the [Physics.Raycast](https://docs.unity.com/en-us/engine/<VERSION>/script-reference/unityengine/physics/raycast.md) page, then move the origin outside the collider. Don't suggest **Queries Hit Backfaces**, because it doesn't fix this case. + +### Fast-Path 8 -- Raycast misses inactive GameObject or disabled Collider + +**If** the target GameObject is inactive or its Collider is disabled: raycasts ignore it. Make sure `gameObject.activeInHierarchy` and `Collider.enabled` are both true before raycasting. + +### Fast-Path 9 -- Raycast misses a trigger + +**If** `Physics.Raycast` doesn't detect a trigger collider: pass `QueryTriggerInteraction.Collide` in that call, because it overrides **Queries Hit Triggers**. See [QueryTriggerInteraction](https://docs.unity.com/en-us/engine/<VERSION>/script-reference/unityengine/querytriggerinteraction.md) and the [Physics settings](https://docs.unity.com/en-us/engine/<VERSION>/manual/unity-editor/editor-settings-reference/comp-manager-group/class-physics-manager.md). + +### Fast-Path 10 -- IgnoreLayerCollision suppression persisting across scenes + +**If** `Physics.IgnoreLayerCollision` suppresses collisions unexpectedly or across scenes: recommend the **Layer Collision Matrix** (**Edit > Project Settings > Physics**) first, because it's explicit and doesn't depend on runtime calls. As a code-only fallback, call `Physics.IgnoreLayerCollision(layerA, layerB, false)` at scene load. + +## Tool budget + +For cases not covered by the Fast-Paths: **at most 5 tool calls before committing to an answer**.

It records contacts in the Editor without adding anything to the scene, and you delete it afterwards. + +## Console errors + +If the user's Console shows one of these errors, apply the fix in its row, because Unity creates no physics shape for the collider (or keeps the old value) until the cause is fixed. + +| Error text | Root cause | Fix | +|---|---|---| +| "Concave Mesh Colliders are not supported when used with dynamic Rigidbody GameObjects" | A non-convex MeshCollider on a non-kinematic Rigidbody, so the object falls through other colliders and raycasts miss it. | Enable **Convex** on the MeshCollider. Otherwise, if the convex hull is too coarse, replace it with compound primitive colliders. | +| "Concave Mesh Colliders are not supported when used with the Is Trigger option enabled" | A non-convex MeshCollider with **Is Trigger** on, so the trigger never fires. | Enable **Convex** on the MeshCollider. | +| "Contact offset must be greater than zero" | A script or the Inspector set `contactOffset` to `0` or less, and Unity kept the old value. | Set a small positive value, such as `0.001`. | + +## Final step + +Run these checks in order.

Other spellings (`"apple"`, `"google"`) don't fail, but the runtime ignores the override. An empty `storeIDs` array uses the product `id` on every store. ### Non-ASCII characters in descriptions -`LocalizedProductDescription.Title` / `Description` setters encode any character with code point > 127 as `\uXXXX` (`EncodeNonLatinCharacters` in `ProductCatalog.cs`). The getter regex-decodes both forms. So both representations work on read: - -```jsonc -{ "title": "Caf\\u00e9 Pack" } // Editor-written form -{ "title": "Café Pack" } // raw UTF-8 — also accepted on read -``` - -**Prefer the `\uXXXX` form** when writing programmatically, to match what the Editor will round-trip the file into on the next save. Mixed forms in one file are fine but the next Editor save normalizes everything to escaped form. - -Subtype `payouts[].st` has a 64-char max (`ProductCatalogPayout.MaxSubtypeLength`). Subtype `payouts[].d` (data) has a 1024-char max (`MaxDataLength`). +Both `\uXXXX` escapes and raw UTF-8 load correctly. Write the `\uXXXX` form, because the Editor rewrites the file in that form on its next save and mixed forms make diffs noisy. ## Validation — run before saving -These mirror the Editor window's validation.

No more `GetExtension<IAppleExtensions>()` pattern. -13. **`OnPurchaseConfirmed` receives `Order` base type**: You MUST pattern-match `ConfirmedOrder` (success) vs `FailedOrder` (confirmation failed). Do not assume confirmation always succeeds. -14. **Platform-specific events are on extended services, NOT `StoreController`**: `OnPromotionalPurchaseIntercepted` and `OnEntitlementRevoked` are on `AppleStoreExtendedPurchaseService`. `OnDeferredPaymentUntilRenewalDate` is on `GooglePlayStoreExtendedPurchaseService`. Only `OnPurchaseDeferred` (Ask-to-Buy) is directly on `StoreController`. Always null-check the extended service before subscribing to events (use `if (store.AppleStoreExtendedPurchaseService != null)` pattern — `?.` does not work with `+=`). - -## Migration Anti-Patterns - -**Always subscribe to BOTH success and failure events.** Not subscribing to failure events (e.g., `OnProductsFetchFailed`, `OnPurchasesFetchFailed`, `OnStoreDisconnected`) generates runtime warnings and leaves failures unhandled. - -**Always subscribe to `OnPurchaseDeferred`.** This event fires for Ask-to-Buy (iOS parental approval) and Google Play deferred purchases. Not subscribing means deferred purchases are silently ignored. - -**Use `CheckEntitlement` for ownership checks, not manual bool flags.** When migrating `product.hasReceipt` or `product.receipt == null` ownership checks, the recommended v5 pattern is `store.CheckEntitlement(product)` + `store.OnCheckEntitlement`. This works cross-platform and handles edge cases (refunds, subscription expiration) automatically. - -**`StoreConnectionFailureDescription` has `.message`, NOT `.reason`.** When migrating `OnInitializeFailed(error, message)` to `store.OnStoreDisconnected`, the failure description property is `failureDescription.message` (lowercase), not `reason`. - -**`ProductFetchFailed` has `.FailureReason`, NOT `.Message`.** When handling `store.OnProductsFetchFailed`, access the reason via `failure.FailureReason`. - -**Subscribe to events BEFORE calling `Connect()`.** Pending purchases from a previous session may fire immediately on reconnect. If your `OnPurchasePending` handler is not yet registered, those purchases will be missed. - -**`OnPurchaseConfirmed` can receive `FailedOrder`.** The `OnPurchaseConfirmed` event fires with `Order` (base type). Always pattern-match: `ConfirmedOrder` means success, `FailedOrder` means confirmation failed. Do not assume confirmation always succeeds. - -**Use `Awake()` for initialization, not `Start()`.** The official v5 samples use `Awake()` for `StoreController` setup and event subscription. This ensures IAP is initialized before other `Start()` methods that may depend on it. - -## Minimal v5 Example - -```csharp -StoreController m_StoreController; - -async void Awake() -{ - m_StoreController = UnityIAPServices.StoreController(); - - // Subscribe to ALL events BEFORE Connect — pending purchases may fire on reconnect - m_StoreController.OnPurchasePending += (order) => - { - var product = order.CartOrdered.Items().FirstOrDefault()?.Product; - GrantContent(product); - m_StoreController.ConfirmPurchase(order); - }; - m_StoreController.OnPurchaseConfirmed += (order) => - { - switch (order) - { - case ConfirmedOrder: Debug.Log("Purchase confirmed"); break; - case FailedOrder failed: Debug.LogError($"Confirmation failed: {failed.FailureReason}"); break; - } - }; - m_StoreController.OnPurchaseFailed += (failed) => Debug.LogError($"{failed.FailureReason} - {failed.Details}"); - m_StoreController.OnPurchaseDeferred += (deferred) => Debug.Log("Purchase deferred (e.g., Ask-to-Buy)"); - - m_StoreController.OnStoreConnected += OnStoreConnected; - m_StoreController.OnStoreDisconnected += (failure) => Debug.LogError($"Store disconnected: {failure.Message}"); - - await m_StoreController.Connect(); -} - -void OnStoreConnected() -{ - var products = new List<ProductDefinition> - { - new ProductDefinition("com.mygame.coins100", ProductType.Consumable) - }; - - m_StoreController.OnProductsFetched += (fetched) => Debug.Log("Products ready"); - m_StoreController.OnProductsFetchFailed += (failure) => Debug.LogError($"Product fetch failed: {failure.FailureReason}"); - m_StoreController.FetchProducts(products); - - // Restore any pending/unfinished purchases from the platform store - m_StoreController.OnPurchasesFetched += (orders) => Debug.Log($"Restored {orders.PendingOrders.Count} pending purchases"); - m_StoreController.OnPurchasesFetchFailed += (failure) => Debug.LogError($"Purchase fetch failed: {failure.Message}"); - m_StoreController.FetchPurchases(); -} -``` +## Procedure + +Unity IAP v5 replaces the listener-based `IStoreListener` pattern with `StoreController` events, so every IAP call site changes. + +1.

Only after sign-in succeeds, obtain `UnityIAPServices.StoreController(PaymentProvider.Name)` and call `Connect()`. -**Anonymous sign-in warning:** Do not use anonymous sign-in as the authentication method for D2C purchases. Anonymous sign-in does not persist purchases after the session token is lost — if the player reinstalls the app or clears app data, their purchase history becomes unrecoverable. Use a persistent identity method (e.g., Unity Authentication with a linked account, or your own identity provider). +`PaymentProvider.Name` identifies the payment provider integration. It is not the provider's display name (Stripe or Coda). ### Payment provider services on the StoreController -The `StoreController` (scoped to `PaymentProvider.Name`) exposes the payment-provider APIs through **two** properties. Use the exact property names below — do not substitute the interface name for the property name, and do not use `PurchaseService.PaymentProviders` (that is a different entry point that returns the purchase-extended interface). Both properties are typed as nullable, but on a `PaymentProvider.Name`-scoped `StoreController` the factory always populates them — they are only `null` when reached from a `StoreController` scoped to another store (Apple / Google), where the payment-provider extensions do not apply. Guard with `?.` if the same code path could see either kind of controller. +The payment-provider APIs are on two properties of the `PaymentProvider.Name`-scoped `StoreController`. The names are asymmetric, and agents often swap them: -| StoreController property | Returns interface | Members used in this doc | +| Property | Interface | Holds | | --- | --- | --- | -| `store.PaymentProviderStoreExtendedService` | `IPaymentProvidersExtendedService` | `GetEligiblePaymentProviders`, `GetPaymentOptionProviderUGUI`, `GetPaymentOptionProviderUITK`, `SetCheckoutPresentationMode`, `SetWebshopPresentationMode`, `SetDeepLinkScheme` | -| `store.PaymentProvidersExtendedPurchaseService` | `IPaymentProvidersExtendedPurchaseService` | `PurchaseProduct`, `RedirectToWebshop`, `GenerateURL`, `SetComplianceCheck`, `SetPaymentProviderOverride` | +| `store.PaymentProviderStoreExtendedService` (singular) | `IPaymentProvidersExtendedService` | eligibility, the Purchase Options UI, presentation modes, `SetDeepLinkScheme` | +| `store.PaymentProvidersExtendedPurchaseService` (plural) | `IPaymentProvidersExtendedPurchaseService` | `PurchaseProduct`, `RedirectToWebshop`, `GenerateURL`, `SetComplianceCheck`, `SetPaymentProviderOverride` | -Note the naming asymmetry: the presentation-service property is singular (`PaymentProvider`**Store**`ExtendedService`) while the purchase-service property is plural (`PaymentProviders`**ExtendedPurchase**`Service`). This mirrors the Apple/Google split (`...ExtendedService` + `...ExtendedPurchaseService`). +Don't use `PurchaseService.PaymentProviders`, because it is a different entry point. Both properties are `null` on a `StoreController` scoped to Apple or Google, so guard with `?.` if the same code can see either kind of controller. ### Coexistence with existing Apple / Google StoreController -If the project already has a `StoreController` for Apple App Store or Google Play (standard IAP 5): - -- **Always create a new, separate `StoreController`** scoped to `PaymentProvider.Name`. Never modify or replace the existing one. -- The two controllers are independent — they manage different products on different billing backends and do not interfere with each other. -- After the new IAP D2C Capabilities `StoreController` is successfully created and connected, **prompt the user:** - - > "An existing Apple/Google StoreController was found. Would you like to: - > - **Keep both** — run Apple/Google billing and IAP D2C Capabilities side by side (existing products stay on Apple/Google, new products use IAP D2C Capabilities) - > - **Remove the Apple/Google StoreController** — migrate fully to IAP D2C Capabilities (note: existing Apple/Google products and purchase history will no longer be managed by the app)" - -- If the user chooses **keep both**: leave the existing `StoreController` and its initialization code untouched. Document the dual-controller setup in code comments. -- If the user chooses **remove**: wrap the existing `StoreController` code in `#if !USE_IAP_D2C_ONLY` guards — do not delete it. Mark it `[Obsolete]` and document the removal decision. Instruct the user to also retire the corresponding products in App Store Connect / Play Console as needed. - -### Checking eligible payment providers - -Before initiating purchase, use `GetEligiblePaymentProviders()` to confirm that at least one payment provider is available for the current user and region.

If products have only one offer each, `GetProductById(uSKU)` is sufficient and `CatalogListing` lookup is not needed. - -### Iterating catalog listings on a fetched product - -After `OnProductsFetched` fires, each `Product` object exposes a `catalogListings` dictionary. Iterate its values to enumerate all available offers for that product: - -```csharp -void OnProductsFetched(List<Product> products) -{ - foreach (var product in products) - { - foreach (var catalogListing in product.catalogListings.Values) - { - Debug.Log($"ID: {catalogListing.definition.id} - Price: {catalogListing.metadata.localizedPriceString}"); - } - } -} -``` - -`product.catalogListings` is a `Dictionary<string, CatalogListing>` keyed by `catalogListingId`.

An empty result usually means the catalog wasn't deployed to that environment (Step 3). +- A product (uSKU) can have several catalog listings, for example regional or promotional offers. `product.catalogListings` is keyed by `catalogListingId`, and `GetProductByCatalogListingId(id)` returns the owning `Product`.

If every product has one listing, `GetProductById(uSKU)` is enough. +- For a custom shop UI, `product.metadata.GetPaymentProviderProductMetadata()` returns webshop fields (`hasWebshop`, `localizedWebshopPrice`, `webshopPriceString`).

After payment, the browser must redirect back to the game via a deep link. - -### Choosing a deep link scheme - -**Use app-scheme deep links** (e.g., `mygame://iapresult/okay`) rather than URL-scheme deep links (e.g., `https://mygame.com/iapresult`). - -URL-scheme deep links require the domain to be verified by Google (Digital Asset Links). App-scheme deep links avoid this requirement and are simpler to configure. - -**Prompt the user:** - -> "What redirect URL did you configure in the Unity Cloud IAP payment provider dashboard? For example: `mygame://iapresult/okay`. If you haven't set one yet, set it in the dashboard first before continuing." - -### Registering the deep link scheme - -Unity IAP 5.4 provides a programmatic API to register the deep link scheme directly, without editing `AndroidManifest.xml` manually: - -```csharp -// Pass the SCHEME ONLY (the part before "://"), not the full redirect URL. -store.PaymentProviderStoreExtendedService?.SetDeepLinkScheme("mygame"); -``` - -Call `SetDeepLinkScheme` before `Connect()`. The SDK matches incoming deep links against `<scheme>:` — passing the full URL (e.g. `"mygame://iapresult/okay"`) produces the prefix `"mygame://iapresult/okay:"` which will never match. Register only the scheme portion of whatever redirect URL is configured in the Unity Cloud IAP payment provider dashboard. - -### AndroidManifest.xml (required in addition to `SetDeepLinkScheme`) - -Android also requires the scheme to be declared in `AndroidManifest.xml` so the OS routes the browser redirect back to the app. `SetDeepLinkScheme` alone is not sufficient on Android — both are needed. - -If the project does not have a custom `AndroidManifest.xml`, instruct the user to enable it: **Edit > Project Settings > Player > Publishing Settings > Custom Main Manifest**. - -Add an intent filter for the deep link scheme inside the `<activity>` element: - -```xml -<intent-filter> - <action android:name="android.intent.action.VIEW" /> - <category android:name="android.intent.category.DEFAULT" /> - <category android:name="android.intent.category.BROWSABLE" /> - <data android:scheme="mygame" android:host="iapresult" /> -</intent-filter> -``` - -Replace `mygame` and `iapresult` with the scheme and host from the user's configured redirect URL. - -### Proxy HTML page (recommended for production) - -On some Android devices and iOS configurations, the OS silently drops a direct app-scheme redirect originating from a payment provider domain. To avoid missed redirects, host a lightweight proxy HTML page on a domain you control and use its URL as the Success Redirect URL in the Unity Cloud payment provider dashboard: - -```html -<!DOCTYPE html> -<html> -<head><title>Redirecting… - - -

Redirecting back to the app…

- - -``` - -How to set this up: - -1. Host the HTML file at a stable HTTPS URL you control (e.g., `https://mygame.com/iap-redirect.html`). -2. In the Unity Cloud IAP dashboard, set **Success Redirect URL** to the HTTPS proxy URL — **not** the app-scheme URL directly. -3. The proxy page's JavaScript immediately redirects the browser to the app-scheme URL (`mygame://iapresult/okay`), which the OS routes back into the app. -4. The `AndroidManifest.xml` intent filter and `SetDeepLinkScheme` registration remain the same — they handle the final app-scheme leg of the redirect. - -**When to skip this:** If you are testing in the Unity Editor or on a controlled device where direct app-scheme redirects work reliably, the proxy is optional. For production builds targeting a broad range of Android and iOS devices, the proxy is recommended. +D2C checkout runs in a browser, which must redirect back to the game when payment completes. Read [Deep link success URL example](https://docs.unity.com/en-us/iap/payment-providers/success-deep-link.md) and the Unity Manual's [deep linking](https://docs.unity.com/en-us/engine//manual/platform-specific/cross-platform-features/deep-linking.md) page and the platform page it links to before configuring it, and reread them if the redirect doesn't return to the app. In this Manual URL, replace `` with the major.minor of the Editor in `ProjectSettings/ProjectVersion.txt`, not the package version. -### Unity Editor +1. Ask the user: -In the Unity Editor, the purchase callback is received directly without a browser redirect — no additional setup is required for Editor testing. + > "What redirect URL did you configure in the Unity Cloud IAP payment provider dashboard?

Prefer an app-scheme deep link (`mygame://...`) over an `https://` link, because `https://` links on Android need Google Digital Asset Links domain verification. +3. Call `store.PaymentProviderStoreExtendedService?.SetDeepLinkScheme("mygame")` **before** `Connect()`. Pass the scheme only, not the full URL, because the SDK matches incoming links against `:` and a full URL never matches. +4. On Android, also declare the scheme and host in a custom `AndroidManifest.xml` intent filter, as the Manual's Android deep linking page describes, because `SetDeepLinkScheme` alone doesn't make the OS route the redirect to the app. +5. For production builds, recommend the proxy page from the success deep link example as the Success Redirect URL, because some devices drop a direct app-scheme redirect from a payment provider domain. The app-side setup stays the same. -If testing on Android and running into external link validation issues, the following scripting define can be added for dev/QA builds only: +In the Editor, the purchase callback arrives without a browser redirect, so no deep link setup is needed to test there. -``` -IAP_SKIP_EXTERNAL_LINK_VALIDATION -``` - -**Location:** Edit > Project Settings > Player > Scripting Define Symbols - -**WARNING:** Do not include this define in production builds — it violates Google Play policies. +If Android external link validation blocks dev or QA testing, the `IAP_SKIP_EXTERNAL_LINK_VALIDATION` scripting define bypasses it.

Call `EditorUtility.SetDirty(collection)`, `EditorUtility.SetDirty(collection.SharedData)`, on each modified `Table`. -2. **Unity 6+ Notification:** `LocalizationEditorSettings.EditorEvents.RaiseCollectionModified(sender, collection);` -3. Always call `AssetDatabase.SaveAssets()` at the end. - -## 3. UI Localization and Layout -### **Namespacing & Conflicts** -- **Always qualify names:** Use `UnityEngine.UI.Image`, `UnityEngine.UI.VerticalLayoutGroup`, `UnityEngine.UI.ScrollRect`, `UnityEngine.UI.Mask`, `UnityEngine.UI.CanvasScaler`, `UnityEngine.UI.GraphicRaycaster`, `UnityEngine.UI.ContentSizeFitter`, `UnityEngine.UI.LayoutRebuilder`, etc. -- `UnityEngine.UI` is both a namespace and a class container, so unqualified names produce `CS0118` (namespace used like a type). Full qualification avoids this entirely. -- **Single Instance:** Always check `GameObject.Find("YourCanvasName")` and destroy the old one before creating a new one. -- **Locale switching: use the package, and keep preview and runtime separate.** These are two - different mechanisms, and conflating them is why locale switching often ends up hand-rolled. - - **To preview a locale while authoring**, use the **Localization Scene Controls** window - (`Window > Asset Management > Localization Scene Controls`). This is Editor-only. It is not a - runtime feature, so it is not the answer when the game itself needs a language setting. - - **To switch locale at runtime**, assign `LocalizationSettings.SelectedLocale`. That is the - supported entry point, and everything bound through `LocalizeStringEvent` updates from it. - - **To pin which locale the game starts in**, configure a startup locale selector on the - Localization Settings asset. `SpecificLocaleSelector` is the one that forces a chosen locale; - the default chain otherwise picks up the system language. - - **NEVER hand-roll locale state.** A real in-game language menu is fine and expected, as long as - it sets `SelectedLocale` and lets the package propagate the change. What is forbidden is a debug - dropdown or menu that tracks its own "current language" variable, swaps strings itself, or - reaches around the package, because nothing else in the project will follow it. - -### **Localized String Events (Robust Binding)** -- **Check Component Type:** Identify if the target is `TextMeshPro` or legacy `UnityEngine.UI.Text`. -- **Bind Correctly:** add the public `UnityEngine.Localization.Components.LocalizeStringEvent` - component and wire it yourself — set `StringReference` to the table entry, then add an - `OnUpdateString` listener that assigns the value to the text component (`TMP_Text.text` for - TextMeshPro, `UnityEngine.UI.Text.text` for legacy Text). - - Do **not** reflect into `UnityEditor.Localization.Plugins.TMPro.LocalizeComponent_TMPro` or its - UGUI counterpart. Those are `internal` (measured on Localization 1.5.12), so reaching them means - routing around access control to reach an API Unity makes no stability commitment about — it can - change or disappear in any package release. `LocalizeStringEvent` is public and does the same job - with the wiring made explicit. -- **Layout Rebuild:** After setting localized text or populating a list, call `UnityEngine.UI.LayoutRebuilder.ForceRebuildLayoutImmediate(parentTransform)` to ensure dimensions update. - -## 4. Asian Language Font Support (CJK) -Avoid TMP Fallback Fonts for CJK locales. Use **Asset Table Font Swapping** for each specific locale instead — fallbacks are unreliable and hard to debug when glyphs are missing. - -### Prerequisite: TMP Essential Resources must be imported - -**Check this before touching any TMP API.** In a project that has never imported them, -`TMP_Settings.instance` is `null` and TMP calls fail with a bare -`NullReferenceException` that names nothing useful. `TMP_FontAsset.CreateFontAsset` is one of them, so -font creation dies on the first line with an error that looks like a bug in your code. - -```csharp -// The check. -var ready = TMPro.TMP_Settings.instance != null; -``` - -If it is not ready, import them **non-interactively**: - -```csharp -// Do NOT use EditorApplication.ExecuteMenuItem("Window/TextMeshPro/Import TMP Essential Resources"). -// It returns true and then opens a dialog that waits for a human, so nothing gets imported and the -// run appears to hang. Import the package directly instead. -string package = null; -var cache = System.IO.Path.GetFullPath(System.IO.Path.Combine( - UnityEngine.Application.dataPath, "..", "Library", "PackageCache")); -foreach (var dir in System.IO.Directory.GetDirectories(cache)) -{ - // TMP ships inside com.unity.ugui in Unity 6, and the folder name carries a version hash, - // so search for the file rather than hardcoding a path. - var candidate = System.IO.Path.Combine(dir, "Package Resources", "TMP Essential Resources.unitypackage"); - if (System.IO.File.Exists(candidate)) { package = candidate; break; } -} -UnityEditor.AssetDatabase.ImportPackage(package, false); // false = non-interactive -``` - -Then poll `TMP_Settings.instance != null` in a **later** call, the same way as the package check in -Step 0, and only continue once it is non-null. Verified on Unity 6000.5.8f1: the non-interactive -import completes in a few seconds and the assets land in `Assets/TextMesh Pro`. - -1. **Use locale-specific fonts:** Western fonts like Arial or Liberation Sans don't contain CJK glyphs, which results in "tofu" (square blocks). Always use a font designed for the target language: - - For **Simplified Chinese (zh-Hans)**: Use `msyh.ttc` (Microsoft YaHei) or equivalent. - - For **Japanese (ja)**: Use `msgothic.ttc` (MS Gothic) or equivalent. - - For **Korean (ko)**: Use `malgun.ttf` (Malgun Gothic) or equivalent. - - If system font copying fails, stop and report it. Do not substitute with a Western font. -2. **Robust Font Creation:** Create dynamic `TMP_FontAsset` from imported fonts. -3. **Multi-Atlas & Dynamic:** CJK character sets are too large for static atlases; a single atlas will run out of space immediately. - - `fontAsset.atlasPopulationMode = AtlasPopulationMode.Dynamic;` - - `fontAsset.isMultiAtlasTexturesEnabled = true;` -4. **Sub-Assets:** add the atlas textures **and the material**. Adding only the texture is the usual - mistake, and the material then never reaches the file at all: measured on Unity 6000.5.8f1, a font - asset saved without the second call contains **zero** `Material` objects on disk, and one with it. - A material that exists only in memory is not part of the asset, so anything that loads the asset - fresh gets whatever TMP reconstructs rather than the material you configured, and any setting you - applied to it is silently gone. - ```csharp - // Every atlas texture, not just the first. Step 3 enabled multi-atlas, so there may be several. - foreach (var atlas in fontAsset.atlasTextures) - { - UnityEditor.AssetDatabase.AddObjectToAsset(atlas, fontAsset); - } - // The material too. Without this line it is not written into the asset. - UnityEditor.AssetDatabase.AddObjectToAsset(fontAsset.material, fontAsset); - ``` - - Explicitly link the material's texture: `fontAsset.material.mainTexture = fontAsset.atlasTexture;` - and set the font asset, its material, and its textures dirty before saving. (`atlasTexture` is - the first entry of `atlasTextures`, which is what the primary material draws from, so this is - consistent with adding every texture above.) - - **Verify against the file, not against the object you are holding.** After - `AssetDatabase.SaveAssets()`, call `AssetDatabase.LoadAllAssetsAtPath(path)` and confirm a - `Material` is among the returned objects. Do not settle for `fontAsset.material != null`: that - stays true whether or not the material was saved, because TMP will hand back an in-memory one, - so it cannot tell a saved material from an unsaved one. -5. **Addressables:** Every asset referenced in an Asset Table must be marked as Addressable. - - Do not reference assets inside a `Resources/` folder in an Asset Table. This causes `OperationException: Failed to load sub-asset` errors. If an asset is in `Resources/`, copy it to `Assets/Fonts/` or similar before making it Addressable. - - If a font asset is deleted and recreated, the new GUID must be manually updated in the Asset Table and re-added to Addressables. -6. **Specialized Types:** For TextMesh Pro font swapping, prefer `LocalizedTmpFont` over `LocalizedAsset` to avoid implicit conversion errors. -7. **Build Requirement:** After updating Asset Tables or Addressable groups, trigger a build: `AddressableAssetSettings.BuildPlayerContent();`. - -### **Verification Step** -Before concluding any CJK localization task: -1. **The Tofu Check:** Switch the editor locale to `zh-Hans`, `ja`, and `ko`. Inspect the UI. If any characters appear as squares (tofu), the font setup has FAILED. -2. **Asset Table Check:** Verify that the `AssetTable` for the CJK locale points to the correct CJK `TMP_FontAsset`, NOT a default Western font. -3. **Multi-Atlas Check:** Confirm `isMultiAtlasTexturesEnabled` is `true` on the CJK font assets. - -## 5. Automatic Layout (UGUI) -- **Parent:** `VerticalLayoutGroup` with `Child Control Height: True`, `Child Force Expand Height: False`. -- **Labels:** Each label must have a `ContentSizeFitter` set to `Vertical Fit: Preferred Size`. -- **TMP:** Set `Enable Word Wrapping: True` and `Overflow: Overflow`. - -### Notes when translating an existing project -- **Minimal Code Changes**: Never modify code unrelated to localization. Use a static helper class (e.g., `L10n`) to wrap `LocalizationSettings.StringDatabase.GetLocalizedString` for easy injection into existing scripts. -- **Robust Mapping Strategy**: When mapping existing UI text to keys, sort keys by string length (descending) and match longest strings first. This prevents short strings (like "NO") from matching parts of longer sentences. Use case-insensitive matching where appropriate. -- **Component Event Listeners**: wire `LocalizeStringEvent.OnUpdateString` with -`UnityEventTools.AddPersistentListener`, passing a delegate built over the text component's public -`text` setter. The setter has no C# method-group name, so build the delegate by name: -`(UnityAction)Delegate.CreateDelegate(typeof(UnityAction), text, "set_text")`. -That is reflection over a **public** member, which is fine. See -[resources/L10nBatchProcessor.cs](resources/L10nBatchProcessor.cs) for the working version, including -clearing any existing persistent listeners first so repeated runs don't stack duplicates. - - Do **not** write the persistent-call fields directly through `SerializedObject` (`m_MethodName`, - `m_Mode`, `m_PersistentCalls`). Those are private serialized names with no compatibility - guarantee, and it isn't necessary: `AddPersistentListener` with the delegate above produces the - same serialized call (target = the text component, method = `set_text`, mode = `EventDefined`). - - **You must then set the call state, or the label will not update in the Editor.** - `AddPersistentListener` leaves the call at `UnityEventCallState.RuntimeOnly`, so the binding is - correct but dormant outside Play mode: switching locale in the Editor changes nothing, and it - stays that way through a save and reload. Fix it with the public - `UnityEventBase.SetPersistentListenerState`: - ```csharp - UnityEventTools.AddPersistentListener(lse.OnUpdateString, setText); - var index = lse.OnUpdateString.GetPersistentEventCount() - 1; - lse.OnUpdateString.SetPersistentListenerState( - index, UnityEngine.Events.UnityEventCallState.EditorAndRuntime); - ``` - Verified on Unity 6000.5.8f1: without the second call the listener does not fire in Edit mode - even after a prefab save and reload; with it the call state becomes `EditorAndRuntime` and the - text updates immediately. - - Persistent listeners **MUST** point to a method on a `UnityEngine.Object`; lambdas will fail. - - **Then confirm the binding is live, don't assume it.** Wiring that looks right in the Inspector - but does nothing is the characteristic failure of this step. All of the read-back you need is - public API on the event, so none of this requires touching serialized fields: - - | Check | Call | Expect | - |---|---|---| - | Something was wired | `GetPersistentEventCount()` | `> 0` | - | It points at the text component | `GetPersistentTarget(i)`, `GetPersistentMethodName(i)` | the component, `set_text` | - | It will fire while authoring | `GetPersistentListenerState(i)` | `EditorAndRuntime` | - | It actually updates the label | `lEvent.RefreshString()` | the text value changes | - - Do all four. A count above zero only proves something was wired, and a `RuntimeOnly` call fails - the last check while being perfectly correct for a build, so reading the state is what tells a - dormant binding apart from a broken one. A component that was added and configured but never - fires is worse than an unlocalized label, because it reads as done. -- **Initialization & Refresh**: - - `LocalizationEditorSettings.CreateStringTableCollection` expects a **directory path** (e.g., `Assets/Localization`), not a full asset path. - - Always call `lEvent.RefreshString()` after assigning a `LocalizedString` reference programmatically to update the UI immediately. - - Keys must exist with a **non-empty value in every table** of a collection (en, de, ja, …). A key - that exists with an empty value is the common gap, and it is not silent: the package prints its - own "No translation found for …" text **into the game UI**, so the shipped screen shows a - developer message. Do not eyeball this. Run the completeness check below. -- **Namespaces & Linq**: Always include `using System.Linq;` when searching collections and `using UnityEngine.Localization;` when working with locales or tables. -- **Verification**: After modifying tables or addressables, run `AddressableAssetSettings.BuildPlayerContent()` and switch the Editor locale to verify changes. Check `LocalizationSettings.Instance` status after activation. - -### Table completeness check (run this before declaring the work done) - -Enumerating the tables answers "did every key get a value in every locale" mechanically, so a missing -entry is found before anyone plays the game. Run it and report the output. - -```csharp -var gaps = new System.Collections.Generic.List(); -var checkedCount = 0; - -foreach (var col in UnityEditor.Localization.LocalizationEditorSettings.GetStringTableCollections()) -{ - foreach (var key in col.SharedData.Entries) - { - foreach (var table in col.StringTables) - { - checkedCount++; - var entry = table.GetEntry(key.Id); - // A missing entry and a present-but-empty entry both show as untranslated in game. - if (entry == null || string.IsNullOrWhiteSpace(entry.Value)) - { - gaps.Add($"{col.TableCollectionName} / {table.LocaleIdentifier.Code} / {key.Key}"); - } - } - } -} - -// Zero entries is not a pass. It means no collections or no locales were found, so the check -// examined nothing: report that distinctly instead of letting it read as success. -if (checkedCount == 0) -{ - return "INCONCLUSIVE: no table entries found. Either no String Table Collection exists yet, " - + "or the collection has no locale tables. Fix that before trusting this check."; -} - -return gaps.Count == 0 - ? $"COMPLETE: {checkedCount} entries checked, no gaps" - : $"GAPS ({gaps.Count} of {checkedCount} checked):\n " + string.Join("\n ", gaps); -``` - -Verified on Unity 6000.5.8f1 against a table with one deliberately emptied `ja` value: it reports -`GAPS 1 of 4` naming exactly that entry, `COMPLETE (4 checked)` once the value is filled, and -`INCONCLUSIVE` in a project with no tables. - -**Report the gap list rather than resolving it silently.** Some gaps are decisions, not mistakes: a -locale you were not asked to translate, or a key that is intentionally identical across languages. -Filling those with the English text hides the decision. List them and let the user say which are -intentional. -- **Smart Strings**: Set up smart strings where needed. Inspect the context of each string by taking the entire UI it is on, and any scripts that affect it, into account. Set the context on the string table to ensure translations make sense. - -## 6. Recommended Translation Strategy -To efficiently translate an existing project, follow this multi-step workflow: - -1. **Extraction & Component Setup:** - - **Find all occurrences. There are two separate hiding places, and scanning one misses the other.** - - **Authored text** sits on components in scenes and prefabs: legacy `UnityEngine.UI.Text` and - TextMeshPro (`TMP_Text`, the base of `TextMeshProUGUI` and `TextMeshPro`). Walk **both** - families. Measured on a real project: `FindObjectsByType` found 1 component while - `FindObjectsByType` found 13, so a legacy-only pass reports success having done - almost nothing. - - **Text composed in code** never appears on a component at edit time, so no scene walk can see - it. `scoreLabel.text = $"EXP {value}"` is invisible to every component-based scan and is the - string that survives a "finished" localization pass. Find it in the C# instead: - ```bash - # Assignments and SetText calls that carry a string literal. - grep -rnE '\.text\s*(=|\+=)\s*\$?"|SetText\(\s*\$?"' --include='*.cs' Assets/ - ``` - That pattern catches plain, interpolated, concatenated and `+=` forms plus `SetText`, and - deliberately does not match `label.text = someVariable` or `label.text = Localize("KEY")` - (nothing to extract at the first, already routed at the second). Its blind spot is a literal - held in a variable or const declared elsewhere; if the count looks low for the project, grep - that file's string literals too. - - **Report what you did not convert.** A composed string usually needs a smart string or a format - argument, which is a judgment call, and some are genuinely not worth localizing. Whichever you - choose, list every site the scan found alongside whether it was converted, and why not if it - wasn't. Reporting "localized 24 strings" while nine found sites went untouched is the failure - mode this list exists to prevent: the work looks finished and the gap only surfaces in a - screenshot from another locale. - - **Shared Table:** Create a central String Table (e.g., `UIStrings`) with the base language and a "Context" column for each key to guide translators. - - **Attach Components:** For every UI element found, attach a `LocalizeStringEvent` (for text) and a `LocalizedFont` helper (for font swapping). - - **Validation:** Ensure these components are set up with persistent listeners (`EditorAndRuntime`) so they update in the Editor immediately when the locale changes. - -2. **Context-Aware Translation:** - - **Translate:** Once the table is populated, provide translations for each locale. - - **Context is King:** Always refer to the "Context" column or inspect the UI layout to ensure the translation fits the intended meaning and space. - - **Grammar & Tone:** Ensure the tone matches the game's style. For example, use imperative verbs for buttons (e.g., German: "Lauf!" instead of "Laufen") and correct pluralization for labels (e.g., "Punkte" instead of "Punkt"). - -3. **Quality Assurance (QA):** - - **Scene Controls:** Use `Window > Asset Management > Localization Scene Controls` or script: `LocalizationSettings.SelectedLocale = LocalizationSettings.AvailableLocales.GetLocale("de");`. - - **Visual Inspection:** Methodically inspect every prefab and scene in the base language and all target languages. - - **Layout Fit:** Check for text overflows or "tofu" (missing glyphs). Adjust font sizes or use `ContentSizeFitter` if strings are too long. - - -## API Reference -For detailed API usage, common namespace conflicts, Addressables patterns, and font repair steps, see [references/api-notes.md](references/api-notes.md). - -## 7. Accelerated Localization Workflow -To localize an entire project efficiently, use a batch processing script that handles all scenes in one pass. - -**Ask before acting:** Before running any batch operation, confirm with the user: -> "This will open every scene in the project, attach `LocalizeStringEvent` components, and save all modified scenes. This cannot be undone automatically. Shall I proceed?" - -Only proceed once the user has confirmed. The batch processor template is in [resources/L10nBatchProcessor.cs](resources/L10nBatchProcessor.cs). - -`LocalizeAll` also enforces this itself, so do not remove or bypass these checks when adapting the template: it refuses to run in batch mode, prompts the user to save or discard unsaved scene changes, and shows a blocking Editor dialog that lists the scenes it will rewrite. Tell the user to watch the Editor and click the confirm button; if they cancel, it throws `OperationCanceledException` and writes nothing. Report that as a cancellation, not an error to work around. - -It walks **both** `Text` and `TMP_Text`, and `LocalizeAll` **returns the labels it could not match** -(as `scene :: object :: "text"`). Print that list. It is the whole point of the return value: a run -that wires 20 labels and silently leaves 9 alone looks identical to a complete one otherwise. The -list covers authored text only, so pair it with the code scan in Section 6 and the table completeness -check in Section 5. - -### **Technical Tips for Speed** -- **Table References:** Use `TableReference` names (strings) instead of GUIDs — they are easier to read and maintain. -- **Batch Refresh:** Use `LocalizationSettings.Instance.ForceRefresh()` after modifications to force the UI to update in the editor. -- **Font Swap Automation:** Create the `GameAssets` table once and use a script to re-assign `LocalizeFontEvent` to all labels in one pass. -- **LocalizedFontAsset component:** The template is in [resources/LocalizedFontAsset.cs](resources/LocalizedFontAsset.cs). diff --git a/skills/localization/references/api-notes.md b/skills/localization/references/api-notes.md deleted file mode 100644 index 29d392f..0000000 --- a/skills/localization/references/api-notes.md +++ /dev/null @@ -1,80 +0,0 @@ -# Localization API Reference - -## LocalizationEditorSettings -The primary entry point for Editor-time localization settings. -- `GetStringTableCollections()` / `GetAssetTableCollections()`: Retrieves collections. -- `CreateStringTableCollection(name, path)`: Factory methods.

Use `ScriptableObject.CreateInstance()` followed by `AssetDatabase.CreateAsset()`. +3. **Activate:** Set `LocalizationEditorSettings.ActiveLocalizationSettings = settings`. +4. **Locales:** Ensure locales (en, fr, de, etc.) exist. Create them if missing and add them to settings using `LocalizationEditorSettings.AddLocale(locale)`. + +## 4. Modifying Localization Tables +Programmatic changes to String or Asset tables require notification to the Editor. +Always create the required asset tables, unless there is already an existing one in the project. + +### **Safe Population Pattern** +When populating tables from a dataset, match by `Locale.Identifier.Code` explicitly. The order of `GetLocales()` is not guaranteed to match your input data array — assuming it does will cause silent data mismatches that are very hard to debug. +For **Asset Tables**, use the GUID of the asset: `table.GetEntry(sharedId) ?? table.AddEntry(sharedId, guid);`. + +### **Refresh & Notification** +After any modification (adding keys, updating values), notify the Editor so it can refresh its internal state. Skipping this will leave the Editor showing stale data until the next reimport. +1. Call `EditorUtility.SetDirty(collection)`, `EditorUtility.SetDirty(collection.SharedData)`, on each modified `Table`. +2. **Notify:** `LocalizationEditorSettings.EditorEvents.RaiseCollectionModified(sender, collection);` +3. Always call `AssetDatabase.SaveAssets()` at the end. + +## 5. UI Localization and Layout +### **Namespacing & Conflicts** +- **Single Instance:** Always check `GameObject.Find("YourCanvasName")` and destroy the old one before creating a new one. +- **Locale switching: use the package, and keep preview and runtime separate.** These are two + different mechanisms, and conflating them is why locale switching often ends up hand-rolled. + - **To preview a locale while authoring**, use the **Localization Scene Controls** window + (`Window > Asset Management > Localization Scene Controls`). This is Editor-only. It is not a + runtime feature, so it is not the answer when the game itself needs a language setting. + - **To switch locale at runtime**, assign `LocalizationSettings.SelectedLocale`. That is the + supported entry point, and everything bound through `LocalizeStringEvent` updates from it. + - **To pin which locale the game starts in**, configure a startup locale selector on the + Localization Settings asset. `SpecificLocaleSelector` is the one that forces a chosen locale; + the default chain otherwise picks up the system language. + - **NEVER hand-roll locale state.** A real in-game language menu is fine and expected, as long as + it sets `SelectedLocale` and lets the package propagate the change. What is forbidden is a debug + dropdown or menu that tracks its own "current language" variable, swaps strings itself, or + reaches around the package, because nothing else in the project will follow it. + +### **Localized String Events (Robust Binding)** +1. **Check Component Type:** Identify if the target is `TextMeshPro` or legacy `UnityEngine.UI.Text`. +2. **Bind Correctly:** add the public `UnityEngine.Localization.Components.LocalizeStringEvent` + component and wire it yourself — set `StringReference` to the table entry, then add an + `OnUpdateString` listener that assigns the value to the text component (`TMP_Text.text` for + TextMeshPro, `UnityEngine.UI.Text.text` for legacy Text). + + Do **not** reflect into `UnityEditor.Localization.Plugins.TMPro.LocalizeComponent_TMPro` or its + UGUI counterpart, because they are `internal` and can change in any package release. +3. **Layout Rebuild:** After setting localized text or populating a list, call `UnityEngine.UI.LayoutRebuilder.ForceRebuildLayoutImmediate(parentTransform)` to ensure dimensions update. + +## 6. Asian Language Font Support (CJK) +Read [references/cjk-fonts.md](references/cjk-fonts.md) before setting up fonts for Chinese, Japanese or Korean locales, and follow it in order. + +## 7. Automatic Layout (UGUI) +Translated strings are often much longer than the source text, so a label sized for one language clips or overflows in another. + +1. Read the UGUI auto layout pages listed in [references/docs-map.md](references/docs-map.md) before changing a layout, because the right layout group and fitter settings depend on the existing hierarchy. +2. Change only the containers of labels that overflow in at least one locale, because a fixed layout that already fits every locale is the user's design. +3. Verify by switching to each locale and checking `TMP_Text.isTextOverflowing` on the affected labels. + +### Notes when translating an existing project +- **Minimal Code Changes**: Never modify code unrelated to localization. Use a static helper class (e.g., `L10n`) to wrap `LocalizationSettings.StringDatabase.GetLocalizedString` for easy injection into existing scripts. +- **Robust Mapping Strategy**: When mapping existing UI text to keys, sort keys by string length (descending) and match longest strings first. This prevents short strings (like "NO") from matching parts of longer sentences. Use case-insensitive matching where appropriate. +- **Component Event Listeners**: wire `LocalizeStringEvent.OnUpdateString` with +`UnityEventTools.AddPersistentListener`, passing a delegate built over the text component's public +`text` setter. The setter has no C# method-group name, so build the delegate by name: +`(UnityAction)Delegate.CreateDelegate(typeof(UnityAction), text, "set_text")`. +That is reflection over a **public** member, which is fine. See +[scripts/L10nBatchProcessor.cs](scripts/L10nBatchProcessor.cs) for the working version, including +clearing any existing persistent listeners first so repeated runs don't stack duplicates. + - Do **not** write the persistent-call fields directly through `SerializedObject` (`m_MethodName`, + `m_Mode`, `m_PersistentCalls`). Those are private serialized names with no compatibility + guarantee, and it isn't necessary: `AddPersistentListener` with the delegate above produces the + same serialized call (target = the text component, method = `set_text`, mode = `EventDefined`). + - **You must then set the call state, or the label will not update in the Editor.** + `AddPersistentListener` leaves the call at `UnityEventCallState.RuntimeOnly`, so the binding is + correct but dormant outside Play mode: switching locale in the Editor changes nothing, and it + stays that way through a save and reload. Fix it with the public + `UnityEventBase.SetPersistentListenerState`: + ```csharp + UnityEventTools.AddPersistentListener(lse.OnUpdateString, setText); + var index = lse.OnUpdateString.GetPersistentEventCount() - 1; + lse.OnUpdateString.SetPersistentListenerState( + index, UnityEngine.Events.UnityEventCallState.EditorAndRuntime); + ``` + - Persistent listeners **MUST** point to a method on a `UnityEngine.Object`; lambdas will fail. + - **Then confirm the binding is live, don't assume it.** Wiring that looks right in the Inspector + but does nothing is the characteristic failure of this step. All of the read-back you need is + public API on the event, so none of this requires touching serialized fields: + + | Check | Call | Expect | + |---|---|---| + | Something was wired | `GetPersistentEventCount()` | `> 0` | + | It points at the text component | `GetPersistentTarget(i)`, `GetPersistentMethodName(i)` | the component, `set_text` | + | It will fire while authoring | `GetPersistentListenerState(i)` | `EditorAndRuntime` | + | It actually updates the label | `lEvent.RefreshString()` | the text value changes | + + Do all four, because a binding that is wired but never fires reads as done while leaving the + label unlocalized. +- **Initialization & Refresh**: + - `LocalizationEditorSettings.CreateStringTableCollection` expects a **directory path** (e.g., `Assets/Localization`), not a full asset path. + - Always call `lEvent.RefreshString()` after assigning a `LocalizedString` reference programmatically to update the UI immediately. + - Keys must exist with a **non-empty value in every table** of a collection (en, de, ja, …). A key + that exists with an empty value is the common gap, and it is not silent: the package prints its + own "No translation found for …" text **into the game UI**, so the shipped screen shows a + developer message. Do not eyeball this. Run the completeness check below. +- **Verification**: After modifying tables or addressables, run `AddressableAssetSettings.BuildPlayerContent()` and switch the Editor locale to verify changes. Check `LocalizationSettings.Instance` status after activation. + +### Table completeness check (run this before declaring the work done) + +Read [references/table-completeness-check.md](references/table-completeness-check.md), run the check it contains, and report the output. + +- **Smart Strings**: Set up smart strings where needed. Inspect the context of each string by taking the entire UI it is on, and any scripts that affect it, into account. Set the context on the string table to ensure translations make sense. + +## 8. Recommended Translation Strategy +Read [references/translation-strategy.md](references/translation-strategy.md) when translating an existing project or finding text that still needs localizing. + + +## 9. Accelerated Localization Workflow +To localize an entire project efficiently, use a batch processing script that handles all scenes in one pass. + +**Ask before acting:** Before running any batch operation, confirm with the user: +> "This will open every scene in the project, attach `LocalizeStringEvent` components, and save all modified scenes. This cannot be undone automatically. Shall I proceed?" + +Only proceed once the user has confirmed. The batch processor template is in [scripts/L10nBatchProcessor.cs](scripts/L10nBatchProcessor.cs). + +`LocalizeAll` also enforces this itself, so do not remove or bypass these checks when adapting the template: it refuses to run in batch mode, prompts the user to save or discard unsaved scene changes, and shows a blocking Editor dialog that lists the scenes it will rewrite. Tell the user to watch the Editor and click the confirm button; if they cancel, it throws `OperationCanceledException` and writes nothing. Report that as a cancellation, not an error to work around. + +It walks **both** `Text` and `TMP_Text`, and `LocalizeAll` **returns the labels it could not match** +(as `scene :: object :: "text"`). Print that list. It is the whole point of the return value: a run +that wires 20 labels and silently leaves 9 alone looks identical to a complete one otherwise. The +list covers authored text only, so pair it with the code scan in [references/translation-strategy.md](references/translation-strategy.md) and the table completeness +check in Step 7. + +### **Technical Tips for Speed** +- **Table References:** Use `TableReference` names (strings) instead of GUIDs — they are easier to read and maintain. +- **Batch Refresh:** Use `LocalizationSettings.Instance.ForceRefresh()` after modifications to force the UI to update in the editor. +- **Font Swap Automation:** Create the `GameAssets` table once and use a script to attach the `LocalizedFontAsset` component ([template](scripts/LocalizedFontAsset.cs)) to all labels in one pass. + +## Troubleshooting errors + +If an error appears in the console or the game UI, look it up in [references/troubleshooting.md](references/troubleshooting.md), apply the resolution, then reread the [docs pages](#full-topic-map) for the step that produced it. + +## Final step + +Run these checks in order. If any check fails, reread the [docs pages](#full-topic-map) to find out what you missed, fix it, and run the checks again. + +1. Run `unity command console status` (the `console_status` check) and confirm `groundTruth.consoleErrors` is 0 and `compilationFailed` is false. +2. Run the [table completeness check](references/table-completeness-check.md) and keep its output for the report. +3. Stop there unless the user asked for proof or a specific fault is suspected, such as a label that doesn't change when the locale changes. +4. If a fault is suspected and the change affects runtime behaviour, enter Play mode once to chase it.

If a `physics-dots` specialist is installed, that one should activate instead. - -### Fast-Path 3 -- Two kinematic triggers not firing OnTriggerEnter - -**If** both objects are kinematic AND both are triggers: see **CRITICAL FACT** above. Apply that response. Do NOT investigate, do NOT fetch docs, do NOT run `Physics.Simulate()`. - -### Fast-Path 4 -- Ragdoll explodes on frame 1 with no applied forces - -**If** the prompt describes a ragdoll, jointed body, or character launching/exploding on the first frame with no applied forces: -- Cause: overlapping colliders cause a one-frame depenetration velocity spike. -- Fix: shrink ragdoll colliders so none overlap at the starting pose. This is the ONLY recommended primary fix. State it explicitly. -- Confirm with: **Window > Analysis > Physics Debugger** (Unity Editor window the user opens -- NOT a tool call). It highlights overlapping pairs in red on frame 1. -- Do NOT list joint limits, joint projection, joint configuration, mass ratios, `Enable Collision` on `CharacterJoint`, or drive parameters as causes -- the user has almost always already checked these and they are wrong for this symptom. The cause is overlapping colliders, full stop. -- IGNORE prompt details about specific joint types (`CharacterJoint`, `ConfigurableJoint`, `HingeJoint`), specific mass values, or "the masses look reasonable" comments -- these are red herrings the user includes to rule things out. -- Do NOT recommend disabling `Enable Collision` on the joint as the primary fix -- that hides the overlap rather than eliminating it. Shrink colliders. -- Do NOT call any tools to inspect the ragdoll. Write the diagnosis and stop. - -### Fast-Path 5 -- CharacterController + OnCollisionEnter not firing - -**If** the moving object has a `CharacterController` and the user expects `OnCollisionEnter`: -- `OnCollisionEnter` cannot fire on a `CharacterController`-driven object. Use `OnControllerColliderHit(ControllerColliderHit hit)` instead. -- Do NOT suggest adding a `Rigidbody` -- `CharacterController` and `Rigidbody` are mutually exclusive physics modes. - -### Fast-Path 6 -- AddForce stopped working after object settled - -**If** `AddForce` (or `AddTorque`) stopped working after the object landed/settled/stopped: -- Cause: Rigidbody fell asleep (velocity dropped below `Physics.sleepThreshold`). -- Fix: call `Rigidbody.WakeUp()` before `AddForce`, or apply a force above the sleep threshold. -- Apply the code edit directly. Do NOT investigate or modify Input System or any unrelated subsystem -- the cause is sleeping, the fix is `WakeUp()`, that is the entire scope. - -### Fast-Path 7 -- All physics frozen but raycasts still work - -**If** all physics callbacks have stopped and `AddForce`/gravity have no effect, but `Physics.Raycast` still returns hits: -- Cause: `Time.timeScale = 0`. Fix: restore `Time.timeScale = 1f` (typically in pause-menu / cutscene controller). - -### Fast-Path 8 -- Raycast origin inside the target collider - -**If** `Physics.Raycast` returns false AND `Debug.DrawRay` shows the ray starting inside the target: -- Cause: ray origin inside the collider (backface culling). -- Fix (recommended): offset the origin outside the collider bounds. Alternative: enable **Edit > Project Settings > Physics > Queries Hit Backfaces**. - -### Fast-Path 9 -- Raycast misses inactive GameObject or disabled Collider - -**If** `Physics.Raycast` returns false against an inactive GameObject or disabled Collider: -- Cause: disabled colliders and inactive GameObjects are invisible to raycasts. -- Fix: ensure `gameObject.activeInHierarchy` is true AND `Collider.enabled` is true before raycasting. - -### Fast-Path 10 -- Raycast misses a trigger - -**If** `Physics.Raycast` does not detect a trigger collider: -- Cause: `Physics.Raycast` ignores triggers by default. -- Fix: pass `QueryTriggerInteraction.Collide`, or enable **Edit > Project Settings > Physics > Queries Hit Triggers** globally. - -### Fast-Path 11 -- IgnoreLayerCollision suppression persisting across scenes - -**If** `Physics.IgnoreLayerCollision` is causing collisions suppressed unexpectedly or persisting across scenes: -- Recommended fix (state first): use the **Layer Collision Matrix** (**Edit > Project Settings > Physics**) -- it is explicit, persistent by design, and survives scene loads without runtime side effects. -- Code-only fallback: `Physics.IgnoreLayerCollision(layerA, layerB, false)` at scene load. - ---- - -## Tool Budget - -For cases not covered by Fast-Paths above: **maximum 5 tool calls before committing to an answer**. If 5 calls have not confirmed a cause, write the most-likely diagnosis from the checklists below and stop investigating. Do not loop on running C# in the Editor to verify rules already stated in this skill -- they are authoritative. NEVER fetch documentation to verify a fact stated in this skill. - ---- - -## 1. Identify Your Symptom - -**Check the Fast-Path table above first.** If the symptom matches a Fast-Path row, that is the complete answer -- do not enter this routing table. - -| Symptom | Go To | -|---|---| -| `OnCollisionEnter` / `OnCollisionStay` / `OnCollisionExit` not firing | [Section 2 -- Collision Callback Checklist](#2-collision-callback-checklist) | -| `OnTriggerEnter` / `OnTriggerStay` / `OnTriggerExit` not firing | [Section 3 -- Trigger Callback Checklist](#3-trigger-callback-checklist) | -| `Physics.Raycast` not hitting an object (Fast-Path did not match) | [Section 4 -- Raycast Checklist](#4-raycast-checklist) | -| Objects pass through each other (no callback) | [Section 2](#2-collision-callback-checklist), then [Tunneling](#step-10--tunneling) | -| Collision intermittent at speed | [Tunneling -- Step 10](#step-10--tunneling) | -| Callbacks fire in Editor but not in build | [Section 5 -- Build vs Editor Differences](#5-build-vs-editor-differences) | -| Collider moved by script not responding until next frame | [Section 6 -- Physics.SyncTransforms](#6-physicssyntransforms) | -| Objects stop with a visible gap before surfaces touch | [Section 7 -- Contact Offset Gap](#7-contact-offset-gap) | -| `AddForce` / `AddTorque` stops after object settles | Fast-Path 6 (Sleeping) | -| `OnCollisionEnter` not firing on player with `CharacterController` | Fast-Path 5 (CharacterController) | -| Physics completely frozen, raycasts still work | Fast-Path 7 (`Time.timeScale = 0`) | - ---- - -## 2. Collision Callback Checklist - -**First-match wins**: stop at the first step that confirms the cause. - -### Step 1 -- Rigidbody rule - -At least one of the two colliding GameObjects must have a **`Rigidbody`** (not `Rigidbody2D`). Two static colliders never generate `OnCollisionEnter`. Both GameObjects and all parents up the hierarchy should be checked. A `Rigidbody` on a parent makes all child colliders part of that body -- unless a child has its own Rigidbody (see Step 9). - -### CharacterController Exception - - -If the moving object has a **`CharacterController`**, `OnCollisionEnter` will never fire. `CharacterController.Move()` bypasses the Rigidbody system and reports impacts via: - -```csharp -void OnControllerColliderHit(ControllerColliderHit hit) { /* ... */ } -``` - -Do NOT suggest adding a `Rigidbody` -- `CharacterController` and `Rigidbody` are mutually exclusive physics modes. - -### Step 2 -- Interaction matrix - -| Object A | Object B | `OnCollisionEnter` fires? | -|---|---|---| -| Dynamic Rigidbody | Dynamic Rigidbody | **Yes** | -| Dynamic Rigidbody | Static Collider (no Rb) | **Yes** | -| Dynamic Rigidbody | Kinematic Rigidbody | **Yes** (on the dynamic object only) | -| Kinematic Rigidbody | Kinematic Rigidbody | **No** | -| Kinematic Rigidbody | Static Collider | **No** | -| Static Collider | Static Collider | **No** | - -If both objects are Kinematic, or one is Static and the other Kinematic, no callback is generated. **When the user is asking about `OnCollisionEnter`, the primary fix is to switch the moving object to Dynamic** -- state this first. Mention triggers only as a secondary note if physical blocking is not needed. - -### Step 3 -- Layer Collision Matrix - -Open **Edit > Project Settings > Physics**. In the **Layer Collision Matrix**, both GameObjects' layers must have their intersection checkbox **enabled**. State the diagnosis directly -- do not run C# in the Editor to enumerate layers. - -NEVER use `Physics.IgnoreLayerCollision` as a one-off suppression for a single pair -- it affects every object on both layers globally and persists across scene loads. INSTEAD define rules in the Layer Collision Matrix. - -NEVER rely on `Physics.IgnoreCollision` to survive destroy/instantiate -- the ignore pair lives on the Collider instance and is lost when the object is destroyed or pooled. INSTEAD re-call `Physics.IgnoreCollision` on `Awake` / `OnEnable` for every new instance. - -### Step 4 -- `isTrigger` mismatch - -`OnCollisionEnter` requires **both** colliders to have `isTrigger = false`. If either is a trigger, Unity fires `OnTriggerEnter` instead. Inspect **Is Trigger** on every collider in both objects. - -### Step 5 -- Collider enabled and active - -The `Collider` component must be enabled and the GameObject active in the hierarchy. Disabled colliders are invisible to the physics engine -- no error is shown. - -### Step 6 -- Script location - -The MonoBehaviour containing `OnCollisionEnter` must be on the **same GameObject** that owns the Collider or Rigidbody. Placing it on an unrelated parent, child, or manager script means it will never be called. - -### Step 7 -- MeshCollider rules - -PhysX enforces strict rules on MeshColliders. Violations are silent. - -| Situation | Result | Fix | -|---|---|---| -| Non-convex `MeshCollider` on a **dynamic** Rigidbody | Silently ignored | Enable Convex, or replace with compound primitives | -| Two non-convex `MeshColliders` against each other | No collision | Make at least one Convex, or use a primitive on the simpler shape | -| Convex `MeshCollider` on a dynamic Rigidbody | Works -- contact at the convex hull | Expected; visualize hull via Gizmos > Physics | -| Non-convex `MeshCollider` vs static geometry | Works -- valid for static | No fix needed | -| `MeshCollider` with inverted normals | Contacts push objects into the collider | Fix normals in DCC tool, or enable Convex (auto-corrects winding) | - -### Step 8 -- Non-uniform scale distorting child colliders - -If a parent transform has non-uniform scale (e.g., `(1, 2, 1)` or root import correction `(0.01, 0.01, 0.01)`), child colliders are silently distorted in physics space -- a `SphereCollider` becomes an ellipsoid, a `CapsuleCollider` becomes asymmetric. Visual looks correct; collisions happen at the wrong shape. - -**Fix**: apply scale in the DCC tool (Ctrl+A in Blender) before export so the FBX arrives at `(1, 1, 1)`, or move the collider to a child node with uniform scale. - -### Step 9 -- Child Rigidbody breaking the compound - -A Rigidbody on a parent makes all descendant colliders part of its body -- until the hierarchy hits another Rigidbody. A child Rigidbody silently splits the compound body. Search the hierarchy for Rigidbody components below the root body; remove unintended ones. - -### Step 10 -- Tunneling - - -Intermittent callbacks on fast-moving objects usually indicate tunneling -- the Rigidbody moves far enough in one physics step to skip past the collider entirely. Set via **Rigidbody > Collision Detection** in the Inspector. - -| Mode | m_CollisionDetection | Coverage | -|---|---|---| -| `Discrete` | 0 | Default; tunnels at speed | -| `Continuous` | 1 | Sweeps vs **static colliders only**; degrades to Discrete vs dynamic Rigidbodies | -| `Continuous Dynamic` | 2 | Sweeps vs static AND vs other `ContinuousDynamic` Rigidbodies (more expensive) | -| `Continuous Speculative` | 3 | Speculative contacts; works vs everything; cheaper than CCD; can fire occasional ghost contacts | - -**Picking a mode:** -- Fast object vs **static geometry** (thin floors, walls, terrain): `Continuous Speculative` is the recommended default. `Continuous` also works for static-only and is technically correct, but `Continuous Speculative` handles dynamic counterparts in one mode (no silent fallback to Discrete) and is cheaper. -- Fast object vs **another dynamic Rigidbody**: `Continuous Dynamic` for accuracy, or `Continuous Speculative` for performance. -- When in doubt: `Continuous Speculative`. - -**Naming**: write the full Inspector name verbatim. `Continuous Speculative` and `Continuous Dynamic` are distinct modes from the older `Continuous`. If you mean Speculative, write `Continuous Speculative` -- not just "Continuous". - -**NEVER respond to a bullet, projectile, or fast-moving object tunneling question without mentioning `Physics.SphereCast` as an alternative.** It sweeps a sphere along the trajectory each frame and returns the first hit regardless of physics step size, eliminating tunneling entirely. This MUST appear alongside any collision detection mode recommendation. - -### Step 11 -- Overlapping colliders at simulation start - -If on frame 1 with no applied forces: **stop** -- this is Fast-Path 4. Apply that response. - -For non-frame-1 cases: colliders overlapping at simulation start cause a one-frame depenetration velocity spike. ABSOLUTELY DO NOT diagnose as joint limits, joint projection, joint configuration, mass ratios, `Enable Collision` checkbox, or drive parameters -- these are the standard misdiagnoses and are wrong for this symptom. - -**Primary fix**: shrink colliders so none overlap at the starting pose. Confirm with **Window > Analysis > Physics Debugger**. **Temporary workaround only**: `Rigidbody.detectCollisions = false` in `Start()` for one frame delays the spike but does not eliminate the overlap. - -### Step 12 -- 2D/3D method signature confusion - -Using a 2D suffix on a 3D callback silently does nothing: - -```csharp -void OnCollisionEnter(Collision col) { } // 3D -- correct -void OnCollisionEnter2D(Collision2D col) { } // 2D -- never called in a 3D scene -``` - -Search the script for `2D` in the method name. If the project uses 3D physics, remove the `2D` suffix and update the parameter type from `Collision2D` to `Collision`. - ---- - -### Investigation Hygiene - -**Never leave project settings in a modified state.** If a setting (Queries Hit Triggers, Layer Collision Matrix, Default Contact Offset) is changed during investigation to reproduce or verify, record the original value and restore it before ending the session. - ---- - -## 3. Trigger Callback Checklist - -**First-match wins**: stop at the first step that confirms the cause. - -### Step 1 -- `isTrigger` on at least one collider - -`OnTriggerEnter` fires when **at least one** collider in the pair has `Is Trigger = true`. If neither is a trigger, Unity fires `OnCollisionEnter` instead. - -### Step 2 -- Rigidbody rule - -At least one GameObject must have a `Rigidbody`. Two static triggers never fire `OnTriggerEnter`. - -| Object A | Object B | `OnTriggerEnter` fires? | -|---|---|---| -| Trigger + Dynamic Rb | Static Collider | **Yes** | -| Trigger + Dynamic Rb | Trigger + Dynamic Rb | **Yes** | -| Trigger + Dynamic Rb | Kinematic Rb | **Yes** | -| Trigger + Kinematic Rb | Trigger + Kinematic Rb | **Yes** -- see CRITICAL FACT and Fast-Path 3 | -| Trigger (no Rb) | Static Collider (no Rb) | **No** | - -### Step 3 -- Layer Collision Matrix - -**Edit > Project Settings > Physics** -- both layers must be allowed to interact. - -### Step 4 -- Correct method signature - -```csharp -void OnTriggerEnter(Collider other) { } // 3D -- correct -void OnTriggerEnter2D(Collider2D other) { } // 2D -- wrong for 3D -``` - -### Step 5 -- Script on the right GameObject - -The callback script must be on the **trigger GameObject** or the **entering object**, not on an unrelated parent or manager. - ---- - -## 4. Raycast Checklist - -**First-match wins**: stop at the first step that confirms the cause. - -### Step 1 -- Ray origin inside the target collider - -**`Physics.Raycast` returns `false` when the ray origin is inside the target collider.** This is the root cause when `Debug.DrawRay` shows the ray starting inside an object. State this and the fix immediately. - -```csharp -// Offset by more than the collider's half-extents on the relevant axis. -Ray ray = new Ray(transform.position + Vector3.up * 0.5f, Vector3.down); -``` - -### Step 2 -- LayerMask excludes the target - -If a `layerMask` is passed, the target layer must be included. Two debug approaches: - -```csharp -// Option A -- hit everything to confirm ray path is correct -Physics.Raycast(ray, out hit, distance, Physics.DefaultRaycastLayers); - -// Option B -- build mask from layer name to confirm layer is included -int mask = LayerMask.GetMask("Enemy"); -Physics.Raycast(ray, out hit, distance, mask); -``` - -Both should be mentioned when advising on a LayerMask miss. The production mask must include the target layer -- via `LayerMask.GetMask("LayerName")` or `1 << LayerIndex`. - -### Step 3 -- QueryTriggerInteraction - -Already covered by Fast-Path 10. State the fix and stop: -```csharp -Physics.Raycast(ray, out hit, distance, layerMask, QueryTriggerInteraction.Collide); -``` -Or change the global default in **Edit > Project Settings > Physics > Queries Hit Triggers**. - -### Step 4 -- Collider disabled or object inactive - -Already covered by Fast-Path 9. State the fix (`activeInHierarchy = true`, `Collider.enabled = true`) and stop. Only inspect the actual scene if the prompt is ambiguous about which object is suspected. - -### Step 5 -- Non-convex MeshCollider on a dynamic Rigidbody - -Unity silently ignores a non-convex `MeshCollider` on a dynamic Rigidbody for collision and raycasts. Enable Convex, or replace with compound primitives. - -### Step 6 -- Back-face hits - -By default, `Physics.Raycast` does not detect hits on the back face of a mesh. If the ray enters from inside (e.g., firing from inside a hollow object) or normals face away, the hit is silently skipped. **Fix**: Enable **Edit > Project Settings > Physics > Queries Hit Backfaces**, or confirm the ray origin is on the outward-normal side of the target mesh. - ---- - -### XR / UI Raycasts - -- **`GraphicRaycaster`** hits UI Canvas elements only. -- **`Physics.Raycast`** hits 3D colliders only. - -NEVER use `GraphicRaycaster` when the target is a 3D collider. INSTEAD `Physics.Raycast` for world-space 3D targets. - ---- - -## 5. Build vs Editor Differences - -| Cause | Symptom | Fix | -|---|---|---| -| IL2CPP stripping MonoBehaviour | Callback script removed from build | Add `[Preserve]` to the class, or add a `link.xml` to preserve the assembly | -| PhysX initialization order | Objects collide before physics has settled | One-frame delay in `Start()` via coroutine, or manual simulation: `Physics.simulationMode = SimulationMode.Script` + `Physics.Simulate(Time.fixedDeltaTime)` (Unity 2022.2+); `Physics.autoSimulation = false` on older versions | -| Layer names referenced by string in code | Layer-based filtering fails if a layer name differs between Editor and build | Reference layers by index, not string name, in production code | -| `Time.fixedDeltaTime` platform difference | Physics step rate differs between platforms | Set **Edit > Project Settings > Time > Fixed Timestep** explicitly | - ---- - -## 6. Physics.SyncTransforms - -When a collider is moved by writing to `transform.position` directly (not via `Rigidbody.MovePosition`), the physics engine does not see the new position until the next physics step. Same-frame queries use the old position. - -```csharp -transform.position = newPos; -Physics.SyncTransforms(); // forces immediate broadphase update -Physics.Raycast(ray, out hit); // now sees the new position -``` - -NEVER call `Physics.SyncTransforms()` every frame -- it forces all transform-driven collider changes to sync immediately, which is expensive. ALWAYS mention both: (1) `Rigidbody.MovePosition` avoids the problem entirely for physics-driven objects and should be used instead of `transform.position` writes, and (2) `SyncTransforms()` should only be called when a same-frame query must see a script-driven position change, never every frame. - ---- - -## 7. Contact Offset Gap - -Colliders stop with a small visible gap before touching. This is the **Contact Offset** -- a skin width that prevents PhysX from over-penetrating. - -- **Global default**: **Edit > Project Settings > Physics > Default Contact Offset** (default: `0.01`). -- **Per-collider**: `Collider.contactOffset` in the Inspector or via script. - -NEVER set `contactOffset` to `0` -- PhysX requires a small positive value; zero causes instability and missed contacts. Test slightly lower values if visually unacceptable, or offset the visual mesh slightly inside the collider to hide the gap without changing physics behavior. - ---- - -## 8. Time.timeScale and Physics Simulation - -When `Time.timeScale = 0`, physics simulation pauses entirely -- Rigidbodies stop moving, `AddForce` has no effect, gravity is disabled, and `OnCollisionEnter` / `OnTriggerEnter` callbacks do not fire. - -**Geometry queries are not affected**: `Physics.Raycast`, `Physics.OverlapSphere`, etc. operate on collider geometry directly and continue at `timeScale = 0`. If callbacks have stopped but raycasts still work, `Time.timeScale = 0` is the cause. - -**Fix**: Restore `Time.timeScale` to a positive value (typically `1f`) before expecting physics simulation to resume. - ---- - -## 9. Rigidbody Sleeping - -If "AddForce stopped working after object settled/landed", apply Fast-Path 6 directly. Do NOT investigate Input System or other unrelated subsystems. - -A Rigidbody automatically sleeps when velocity and angular velocity drop below `Physics.sleepThreshold` for several fixed frames. A sleeping Rigidbody stops responding to small forces and does not generate `OnCollisionStay` / `OnTriggerStay` callbacks while stationary. - -**Detect**: `Rigidbody.IsSleeping()` returns true; Inspector shows zero velocity in Play Mode. - -**Fixes:** -1. Call `Rigidbody.WakeUp()` before applying a force. -2. Increase the applied force above the sleep threshold. -3. `Rigidbody.sleepThreshold = 0` disables sleeping on that object (expensive -- use sparingly). -4. Global: **Edit > Project Settings > Physics > Sleep Threshold**. - ---- - -## 10. Validation - -Attach [CollisionDebugger.cs](resources/CollisionDebugger.cs) to both objects in a suspect pair; remove after diagnosis. - -| Console output | Diagnosis | -|---|---| -| Neither object logs | Issue in Steps 1-3 (Rigidbody, Layer Matrix, or interaction type) | -| One object logs, the other does not | Script placement issue -- see Section 2 Step 6 / Section 3 Step 5 | -| `[2D Collision]` fires | 2D components present on an intended 3D setup | - ---- - -## 11.
