loaded

Whether the asset is loaded or not

meta description
Type Boolean
Defined in cocos2d/core/assets/CCAsset.js:57
url

Points to the true url of this asset's native object, only valid when asset is loaded and asyncLoadAsset is not enabled. The difference between nativeUrl and url is that the latter is final path, there is no needs to transform url by md5 and subpackage. Besides, url may points to temporary path or cached path on mini game platform which has cache mechanism (WeChat etc). If you want to make use of the native file on those platforms, you should use url instead of nativeUrl.

meta description
Type String

nativeUrl

Returns the url of this asset's native object, if none it will returns an empty string.

meta description
Type String

_native

Serializable url for native asset.

meta description
Type String

_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

Checks whether the EventTarget object has any callback registered for a specific type of event.

meta description
Returns Boolean
Defined in cocos2d/core/event/event-target.js:69
Parameters
  • type String The type of event.
on

Register an callback of a specific event type on the EventTarget. This type of event should be triggered via emit.

meta description
Returns Function
Defined in cocos2d/core/event/event-target.js:77
Parameters
  • type String A string representing the event type to listen for.
  • callback Function The callback that will be invoked when the event is dispatched.
                           The callback is ignored if it is a duplicate (the callbacks are unique).
    
    • arg1 Any arg1
    • arg2 Any arg2
    • arg3 Any arg3
    • arg4 Any arg4
    • arg5 Any arg5
  • target Object The target (this object) to invoke the callback, can be null
Examples
eventTarget.on('fire', function () {
    cc.log("fire in the hole");
}, node);
off

Removes the listeners previously registered with the same type, callback, target and or useCapture, if only type is passed as parameter, all listeners registered with that type will be removed.

meta description
Defined in cocos2d/core/event/event-target.js:119
Parameters
  • type String A string representing the event type being removed.
  • callback Function The callback to remove.
  • target Object The target (this object) to invoke the callback, if it's not given, only callback without target will be removed
Examples
// register fire eventListener
var callback = eventTarget.on('fire', function () {
    cc.log("fire in the hole");
}, target);
// remove fire event listener
eventTarget.off('fire', callback, target);
// remove all fire event listeners
eventTarget.off('fire');
targetOff

Removes all callbacks previously registered with the same target (passed as parameter). This is not for removing all listeners in the current event target, and this is not for removing all listeners the target parameter have registered. It's only for removing all listeners (callback and target couple) registered on the current event target by the target parameter.

meta description
Defined in cocos2d/core/event/event-target.js:163
Parameters
  • target Object The target to be searched for all related listeners
once

Register an callback of a specific event type on the EventTarget, the callback will remove itself after the first time it is triggered.

meta description
Defined in cocos2d/core/event/event-target.js:182
Parameters
  • type String A string representing the event type to listen for.
  • callback Function The callback that will be invoked when the event is dispatched.
                           The callback is ignored if it is a duplicate (the callbacks are unique).

    cc.log("this is the callback and will be invoked only once");
}, node);
dispatchEvent

Send an event with the event object.

meta description
Defined in cocos2d/core/event/event-target.js:208
Parameters
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:184
serialize

应 AssetDB 要求提供这个方法

meta description
Returns String

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.

Parameters
_setRawAsset

Set native file name for this asset.

meta description
Defined in cocos2d/core/assets/CCAsset.js:224
Parameters
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 any more. 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; } } }

Called before the object being destroyed.

The customized serialization for this object. (Editor Only)
