Animation Class

Extends Component, EventTarget(mixin)

Module: cc

The animation component is used to play back animations.

Animation provide several events to register:

  • play : Emit when begin playing animation
  • stop : Emit when stop playing animation
  • pause : Emit when pause animation
  • resume : Emit when resume animation
  • lastframe : If animation repeat count is larger than 1, emit when animation play to the last frame
  • finished : Emit when finish playing animation

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

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

meta description
Returns AnimationState
Defined in cocos2d/core/components/CCAnimation.js:452
Parameters
removeClip

Remove clip from the animation list. This will remove the clip and any animation states based on it. If there are animation states depand on the clip are playing or clip is defaultClip, it will not delete the clip. But if force is true, then will always remove the clip and any animation states based on it. If clip is defaultClip, defaultClip will be reset to null

meta description
Defined in cocos2d/core/components/CCAnimation.js:493
Parameters
  • clip AnimationClip
  • force Boolean If force is true, then will always remove the clip and any animation states based on it.
sample

Samples animations at the current state.
This is useful when you explicitly want to set up some animation state, and sample it once.

meta description
Defined in cocos2d/core/components/CCAnimation.js:547
Parameters
on

Register animation event callback. The event arguments will provide the AnimationState which emit the event. When play an animation, will auto register the event callback to the AnimationState, and unregister the event callback from the AnimationState when animation stopped.

meta description
Returns Function
Defined in cocos2d/core/components/CCAnimation.js:570
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).
    
  • state cc.AnimationState
  • target Object The target (this object) to invoke the callback, can be null
  • useCapture Boolean When set to true, the capture argument prevents callback
                           from being invoked when the event's eventPhase attribute value is BUBBLING_PHASE.
                           When false, callback will NOT be invoked when event's eventPhase attribute value is CAPTURING_PHASE.
                           Either way, callback will be invoked when event's eventPhase attribute value is AT_TARGET.
    
Examples
onPlay: function (type, state) {
    // callback
}

// register event to all animation
animation.on('play', this.onPlay, this);
off

Unregister animation event callback.

meta description
Defined in cocos2d/core/components/CCAnimation.js:616
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
  • useCapture Boolean Specifies whether the callback being removed was registered as a capturing callback or not.
                           If not specified, useCapture defaults to false. If a callback was registered twice,
                           one with capture and one without, each must be removed separately. Removal of a capturing callback
                           does not affect a non-capturing version of the same listener, and vice versa.
    
Examples
// unregister event to all animation
animation.off('play', this.onPlay, this);
hasEventListener

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:68

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

Returns the component of supplied type if the node has one attached, null if it doesn't.
You can also get component in the node by passing in the name of the script.

meta description
Returns Component

Parameters
Examples
// get sprite component.
var sprite = node.getComponent(cc.Sprite);

Returns all components of supplied Type in the node.

meta description
Returns Component[]
Defined in cocos2d/core/components/CCComponent.js:372
Parameters
Examples
var sprites = node.getComponents(cc.Sprite);
var tests = node.getComponents("Test");
getComponentInChildren

Returns the component of supplied type in any of its children using depth first search.

meta description
Returns Component
Defined in cocos2d/core/components/CCComponent.js:390
Parameters
Examples
var sprite = node.getComponentInChildren(cc.Sprite);
var Test = node.getComponentInChildren("Test");
getComponentsInChildren

Returns the components of supplied type in self or any of its children using depth first search.

meta description
Returns Component[]
Defined in cocos2d/core/components/CCComponent.js:408
Parameters
Examples
var sprites = node.getComponentsInChildren(cc.Sprite);
var tests = node.getComponentsInChildren("Test");
_getLocalBounds

If the component's bounding box is different from the node's, you can implement this method to supply a custom axis aligned bounding box (AABB), so the editor's scene view can perform hit test properly.

meta description
Defined in cocos2d/core/components/CCComponent.js:428
Parameters
  • out_rect Rect the Rect to receive the bounding box
onRestore

onRestore is called after the user clicks the Reset item in the Inspector's context menu or performs an undo operation on this component.

If the component contains the "internal state", short for "temporary member variables which not included
in its CCClass properties", then you may need to implement this function.

The editor will call the getset accessors of your component to record/restore the component's state
for undo/redo operation. However, in extreme cases, it may not works well. Then you should implement
this function to manually synchronize your component's "internal states" with its public properties.
Once you implement this function, all the getset accessors of your component will not be called when
the user performs an undo/redo operation. Which means that only the properties with default value
will be recorded or restored by editor.

Similarly, the editor may failed to reset your component correctly in extreme cases. Then if you need
to support the reset menu, you should manually synchronize your component's "internal states" with its
properties in this function. Once you implement this function, all the getset accessors of your component
will not be called during reset operation. Which means that only the properties with default value
will be reset by editor.

This function is only called in editor mode.

schedule

Schedules a custom selector.

  • repeat Number The selector will be executed (repeat + 1) times, you can use cc.macro.REPEAT_FOREVER for tick infinitely.
  • delay Number The amount of time that the first tick will wait before execution.
Examples
var timeCallback = function (dt) {
  cc.log("time: " + dt);
}
this.schedule(timeCallback, 1);
scheduleOnce

Schedules a callback function that runs only once, with a delay of 0 or larger.

meta description
Defined in cocos2d/core/components/CCComponent.js:572
Parameters
