_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.

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
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.

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
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; } } }
