From 15af1cb98411d863cd287418eeb6c0510b91a9b1 Mon Sep 17 00:00:00 2001 From: cptbtptpbcptdtptp Date: Tue, 2 Jun 2026 01:10:58 +0800 Subject: [PATCH 01/23] refactor(clone): map-based remap + @defaultCloneMode default mode Reworks the prefab/entity clone classifier so reference handling is correct by default and decided by one consistent, declarative mechanism. - Replace CloneUtils hierarchy-path remap with a single source->clone identity map (merged with the dedup map). Fixes the destroyed-entity NPE and the multi-same-type-component indexOf fragility; O(1) remap instead of O(depth). - Add CloneMode.Remap and a type-level @defaultCloneMode(mode) class decorator (set non-enumerably on the prototype) as the default for undecorated fields: Entity/Component -> Remap, ReferResource + Shader/ShaderMacro/ShaderTagKey/ SubFont -> Assignment. Explicit field decorators take precedence. - Decouple populate (copyFrom) from finalize (_cloneTo); _cloneTo always runs. - Delete CloneUtils.

Aligns with Unity [SerializeField] / UE UPROPERTY / Cocos @property: one neutral "managed property" marker, behaviors as orthogonal concerns. - CloneManager walks a cached per-class @property field set (getProperties) instead of `for k in source`; drops per-field CloneMode plumbing, the legacy bridges, and CloneMode.Shallow/Ignore. - Migrate ~70 files: @deepClone/@assignmentClone -> @property, delete @ignoreClone, and add @property to currently-cloned-but-undecorated fields (Camera, Renderer, lighting, physics, particle, postprocess, ui, ...). - Gap-fill decorator-less cloneable classes found via the test suite + a static @property-field-type sweep: physics shape/joint subclasses, PhysicsMaterial, PostProcessEffect(+Parameter), Transition (_target/_interactive), PointLight, particle emitter shapes. - Skin.name made a @property field + parameterless-constructible; function-typed fields are skipped (transient, re-established by the constructor). - Rewrite clone spec tests for the opt-in contract (incl. "unmarked field is not cloned"); fixtures mark @property; Signal tests use the identity-map _cloneTo. Verified: 986 browser tests pass (core 826, ui 64, loader 96).

Bump +1 centrally in the cloner's Assignment branch (no-op for non-ref-counted flyweights) and drop the now-redundant manual bumps in Camera/AudioSource `_cloneTo`. Fixes the same latent leak in TextRenderer/SpriteTransition/etc. for free. - Map/Set members went through a remap-only shortcut (values shared, never deep-cloned or ref-counted). Unify property / Array / Map / Set members through one `_cloneValue` gate. - Register Array/Map/Set in the identity map before recursing, so shared containers dedup and self-referential containers no longer infinite-loop.

Here, the details of script cloning will be explained in detail. +Entity cloning is a common runtime feature. Cloning an entity also clones all its bound components. For example, during initialization you might dynamically create identical entities and place them at different positions according to game logic. ## Entity Cloning -It's very simple, just call the entity's [clone()](/apis/design/#IClone-clone) method to complete the cloning of the entity and its attached components. + +Call the entity's [clone()](/apis/core/#Entity-clone) method to clone the entity along with its entire subtree and all attached components: + ```typescript const cloneEntity = entity.clone(); ``` -## Script Cloning -Scripts are essentially components, so when we call the entity's [clone()](/apis/design/#IClone-clone) function, the engine will not only clone the built-in components but also clone custom scripts. The cloning rules for built-in components have been customized by the official team, and similarly, we have also opened up the cloning capabilities and rules for scripts to developers. The default cloning method for script fields is shallow copy. For example, if we modify the field values of the script and then clone it, the cloned script will retain the modified values without any additional coding. Below is an example of custom script cloning: +## Opt-in Property Model + +The clone system uses an **opt-in** model: only fields marked with the `@property` decorator participate in cloning. Unmarked fields keep their constructor-initialized default value in the clone. + ```typescript -// define a custom script -class CustomScript extends Script{ - /** boolean type.*/ - a:boolean = false; - - /** number type.*/ - b:number = 1; - - /** class type.*/ - c:Vector3 = new Vector3(0,0,0); +import { Script, property } from "@galacean/engine"; +import { Vector3 } from "@galacean/engine"; + +class MyScript extends Script { + // Cloned: marked with @property + @property + speed: number = 10; + + @property + offset: Vector3 = new Vector3(1, 0, 0); + + // NOT cloned: no decorator, keeps constructor default in the clone + private _cache: Map = new Map(); } +``` -// Init entity and script -const entity = engine.createEntity(); -const script = entity.addComponent(CustomScript); -script.a = true; -script.b = 2; -script.c.set(1,1,1); +## Clone Modes -// Clone logic -const cloneEntity = entity.clone(); -const cloneScript = cloneEntity.getComponent(CustomScript); -console.log(cloneScript.a); // output is true. -console.log(cloneScript.b); // output is 2. -console.log(cloneScript.c); // output is (1,1,1). +HOW a `@property` field is cloned depends on its runtime value's type. The clone system inspects the value's `@defaultCloneMode` to determine the strategy: + +| Clone Mode | Behavior | Typical Types | +| :--- | :--- | :--- | +| `CloneMode.Deep` | Recursively deep-clone, producing an independent copy | Vector3, Color, custom classes (default) | +| `CloneMode.Assignment` | Share the same reference; ref-counted resources get +1 | Texture, Mesh, Material, AnimatorController | +| `CloneMode.Remap` | Resolve to the corresponding clone within the cloned subtree | Entity, Component | + +You do not need to specify the mode per field — it is determined automatically by the type of the value the field holds. + +### Deep Clone (default) + +When a `@property` field holds a plain object or a class without `@defaultCloneMode`, it is deep-cloned. Each clone gets its own independent copy: + +```typescript +class MyScript extends Script { + @property + offset: Vector3 = new Vector3(1, 0, 0); +} + +const clone = entity.clone(); +const cloneScript = clone.getComponent(MyScript); + +// Independent copy — modifying one does not affect the other +cloneScript.offset.set(2, 2, 2); +console.log(script.offset); // still (1, 0, 0) ``` -### Clone Decorators -In addition to the default cloning method, the engine also provides "clone decorators" to customize the cloning method for script fields. The engine has four built-in clone decorators: -| Decorator Name | Decorator Description | -| :--- | :--- | -| [ignoreClone](/apis/core/#ignoreClone) | Ignore the field during cloning. | -| [assignmentClone](/apis/core/#assignmentClone) | (Default value, equivalent to not adding any clone decorator) Assign the field during cloning. If it is a basic type, the value will be copied; if it is a reference type, the reference address will be copied. | -| [shallowClone](/apis/core/#shallowClone) | Shallow clone the field during cloning. After cloning, it will maintain its own independent reference and clone all its internal fields by assignment (if the internal field is a basic type, the value will be copied; if the internal field is a reference type, the reference address will be copied). | -| [deepClone](/apis/core/#deepClone) | Deep clone the field during cloning. After cloning, it will maintain its own independent reference, and all its internal deep fields will remain completely independent. | +### Assignment (Shared Reference) + +Asset types like `Material`, `Texture`, and `Mesh` are shared by reference. The clone acquires an additional reference that is released when the clone is destroyed: -We slightly modify the above example and add different "clone decorators" to the four fields in `CustomScript`.

How the sub-properties of the properties are cloned depends on the decorators of the sub-properties. - - If the clone decorators do not meet the requirements, you can implement the [_cloneTo()](/apis/design/#IClone-cloneTo) method to add custom cloning. +If the referenced entity is **outside** the cloned subtree, the original reference is preserved as-is. + +## @defaultCloneMode Decorator + +Use the `@defaultCloneMode` class decorator to control how instances of your custom type behave when they appear in `@property` fields: + +```typescript +import { CloneMode, defaultCloneMode } from "@galacean/engine"; + +// Instances of SharedConfig will be shared (not deep-cloned) across clones +@defaultCloneMode(CloneMode.Assignment) +class SharedConfig { + theme: string = "default"; + maxRetries: number = 3; +} + +class MyScript extends Script { + @property + config: SharedConfig; // Shared by reference due to @defaultCloneMode +} +``` + +Built-in types already have appropriate defaults — you only need `@defaultCloneMode` for your own custom types that should be shared or remapped. + +## Custom Clone Hook + +For advanced scenarios where cloned fields alone are not sufficient (e.g., rebuilding native objects, syncing derived state), implement the `_cloneTo` method: + +```typescript +class MyScript extends Script { + @property + private _radius: number = 1; + + private _nativeShape: NativeShape; // Not cloned (transient) + + _cloneTo(target: MyScript): void { + // Rebuild native state from the cloned fields + target._nativeShape = NativeShape.create(target._radius); + } +} +``` + +The `_cloneTo` hook is called **after** all `@property` fields have been populated on the clone.
