继承于 Asset
模块: cc父模块: cc
预制资源类。

属性(properties)
_createFunction
Cache function to optimize instance creaton.
data
the main cc.Node in the prefab
optimizationPolicy
设置实例化这个 prefab 时所用的优化策略。根据使用情况设置为合适的值,能优化该 prefab 实例化所用的时间。
示例
prefab.optimizationPolicy = cc.Prefab.OptimizationPolicy.MULTI_INSTANCE;
asyncLoadAssets
指示该 Prefab 依赖的资源可否在 Prefab 加载后再延迟加载。
readonly
loaded
该资源是否已经成功加载
nativeUrl
返回该资源对应的目标平台资源的 URL,如果没有将返回一个空字符串。
_native
Serializable url for native asset.
_nativeAsset
The underlying native asset of this asset if one is available.This property can be used to access additional details or functionality releated to the asset.This property will be initialized by the loader if _native
is available.
_uuid
_name
_objFlags
name
该对象的名称。
示例
obj.name = "New Obj";
isValid
表示该对象是否可用(被 destroy 后将不可用)。当一个对象的 destroy
调用以后,会在这一帧结束后才真正销毁。因此从下一帧开始 isValid
就会返回 false,而当前帧内 isValid
仍然会是 true。如果希望判断当前帧是否调用过 destroy
,请使用 cc.isValid(obj, true)
,不过这往往是特殊的业务需求引起的,通常情况下不需要这样。
示例
var node = new cc.Node();
cc.log(node.isValid); // true
node.destroy();
cc.log(node.isValid); // true, still valid in this frame
// after a frame...
cc.log(node.isValid); // false, destroyed in the end of last frame
方法
compileCreateFunction
Dynamically translation prefab data into minimized code.This method will be called automatically before the first time the prefab being instantiated,but you can re-call to refresh the create function once you modified the original prefab data in script.
toString
Returns the asset's url.
The Asset
object overrides the toString()
method of the Object
object.For Asset
objects, the toString() method returns a string representation of the object.JavaScript calls the toString() method automatically when an asset is to be represented as a text value or when a texture is referred to in a string concatenation.
serialize
应 AssetDB 要求提供这个方法
createNode
使用该资源在场景中创建一个新节点。如果这类资源没有相应的节点类型,该方法应该是空的。
参数列表
_setRawAsset
Set native file name for this asset.
参数列表
destroy
销毁该对象,并释放所有它对其它对象的引用。实际销毁操作会延迟到当前帧渲染前执行。从下一帧开始,该对象将不再可用。您可以在访问对象之前使用 cc.isValid(obj) 来检查对象是否已被销毁。
示例
obj.destroy();
_destruct
Clear all references in the instance.
NOTE: this method will not clear the getter or setter functions which defined in the instance of CCObject. You can override the _destruct method if you need, for example: _destruct: function () { for (var key in this) { if (this.hasOwnProperty(key)) { switch (typeof this[key]) { case 'string': this[key] = ''; break; case 'object': case 'function': this[key] = null; break; } } }
_onPreDestroy
Called before the object being destroyed.
_serialize
The customized serialization for this object. (Editor Only)
参数列表
_deserialize
Init this object from the custom serialized data.
参数列表
data
Object the serialized json datactx
