Resource

Base class for engine resources, such as:

• Texture
• Mesh
• Material

• Resource
  • .constructor(engine, index) ⇒ Resource
  • .engine
  • .index
  • .isDestroyed
  • .origin
  • .equals(other) ⇒ boolean

.constructor(engine: WonderlandEngine, index: number) ⇒ Resource 

.engine: WonderlandEngine 

Hosting engine instance.

.index: number 

Index of this resource in the Scene’s manager.

.isDestroyed: boolean 

true if the object is destroyed, false otherwise.

If erasePrototypeOnDestroy is true, reading a class attribute / method will throw.

.origin: null | Prefab 

Scene with which the resource was originally loaded.

Note: If the scene has since been destroyed, returns null.

Example 

 1const prefab = await engine.loadPrefab('Prefab.bin');
 2
 3const meshA = engine.meshes.create({vertexCount: 1});
 4console.log(meshA.origin === prefab); // false
 5
 6const components = prefab.getComponents('mesh');
 7for (const component of components) {
 8    const original = component.mesh.origin;
 9    console.log(prefab === original); // true
10}

.equals(other: undefined | null | Resource) ⇒ boolean 

Checks equality by comparing ids and not the JavaScript reference.

Deprecated: Use JavaScript reference comparison instead:

1const meshA = engine.meshes.create({vertexCount: 1});
2const meshB = engine.meshes.create({vertexCount: 1});
3const meshC = meshB;
4console.log(meshA === meshB); // false
5console.log(meshA === meshA); // true
6console.log(meshB === meshC); // true
