_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.

name

The name of the object.

meta description
Type String
Defined in cocos2d/core/platform/CCObject.js:240
Examples
obj.name = "New Obj";
isValid

Indicates whether the object is not yet destroyed. (It will not be available after being destroyed)
When an object's destroy is called, it is actually destroyed after the end of this frame. So isValid will return false from the next frame, while isValid in the current frame will still be true. If you want to determine whether the current frame has called destroy, use cc.isValid(obj, true), but this is often caused by a particular logical requirements, which is not normally required.

meta description
Type Boolean
Defined in cocos2d/core/platform/CCObject.js:258
Examples
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

Methods

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.

meta description
Returns String
Defined in cocos2d/core/assets/CCAsset.js:223
serialize

Provide this method at the request of AssetDB.

meta description
Returns String
Defined in cocos2d/core/assets/CCAsset.js:243
createNode

Create a new node using this asset in the scene.
If this type of asset dont have its corresponding node type, this method should be null.

meta description
Defined in cocos2d/core/assets/CCAsset.js:257
Parameters
_setRawAsset

Set native file name for this asset.

meta description
Defined in cocos2d/core/assets/CCAsset.js:272
Parameters
addRef

Add references of asset

meta description
Returns Asset
Defined in cocos2d/core/assets/CCAsset.js:294
decRef

Reduce references of asset and it will be auto released when refCount equals 0.

meta description
Returns Asset
Defined in cocos2d/core/assets/CCAsset.js:312
destroy

Destroy this Object, and release all its own references to other objects.
Actual object destruction will delayed until before rendering. From the next frame, this object is not usable anymore. You can use cc.isValid(obj) to check whether the object is destroyed before accessing it.

meta description
Returns Boolean
Defined in cocos2d/core/platform/CCObject.js:293
Examples
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;
        }
    }
}
