Animation Class

Extends Component

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

  • currentClip AnimationClip Current played clip.
  • _clips AnimationClip[] All the clips used in this animation.
  • playOnLoad Boolean Whether the animation should auto play the default clip when start game.
  • __eventTargets Array Register all related EventTargets, all event callbacks will be removed in _onPreDestroy
  • node Node The node this component is attached to. A component is always attached to a node.
  • uuid String The uuid for editor.
  • _enabled Boolean
  • enabled Boolean indicates whether this component is enabled or not.
  • enabledInHierarchy Boolean indicates whether this component is enabled and its node is also active in the hierarchy.
  • _isOnLoadCalled Number Returns a value which used to indicate the onLoad get called or not.
  • _name String
  • _objFlags Number
  • name String The name of the object.
  • isValid Boolean Indicates whether the object is not yet destroyed.
Methods
  • getClips Get all the clips used in this animation.
  • play Plays an animation and stop other animations.
  • playAdditive Plays an additive animation, it will not stop other animations. If there are other animations playing, then will play several animations at the same time.
  • stop Stops an animation named name. If no name is supplied then stops all playing animations that were started with this Animation.
    Stopping an animation also Rewinds it to the Start.
  • pause Pauses an animation named name. If no name is supplied then pauses all playing animations that were started with this Animation.
  • resume Resumes an animation named name. If no name is supplied then resumes all paused animations that were started with this Animation.
  • setCurrentTime Make an animation named name go to the specified time. If no name is supplied then make all animations go to the specified time.
  • getAnimationState Returns the animation state named name. If no animation with the specified name, the function will return null.
  • addClip Adds a clip to the animation with name newName. If a clip with that name already exists it will be replaced with the new clip.
  • 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
  • sample Samples animations at the current state.
    This is useful when you explicitly want to set up some animation state, and sample it once.
  • 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.
  • off Unregister animation event callback.
  • 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.
  • once Register an callback of a specific event type on the EventTarget, the callback will remove itself after the first time it is triggered.
  • dispatchEvent Dispatches an event into the event flow. The event target is the EventTarget object upon which the dispatchEvent() method is called.
  • emit Send an event to this object directly, this method will not propagate the event to any other objects. The event will be created from the supplied message, you can get the "detail" argument from event.detail.
  • update Update is called every frame, if the Component is enabled.
  • lateUpdate LateUpdate is called every frame, if the Component is enabled.
  • __preload __preload is called before every onLoad. It is used to initialize the builtin components internally, to avoid checking whether onLoad is called before every public method calls. This method should be removed if script priority is supported.
  • onLoad When attaching to an active node or its node first activated. onLoad is always called before any start functions, this allows you to order initialization of scripts.
  • start Called before all scripts' update if the Component is enabled the first time. Usually used to initialize some logic which need to be called after all components' onload methods called.
  • onEnable Called when this component becomes enabled and its node is active.
  • onDisable Called when this component becomes disabled or its node becomes inactive.
  • onDestroy Called when this component will be destroyed.
  • onFocusInEditor
  • onLostFocusInEditor
  • resetInEditor Called to initialize the component or node’s properties when adding the component the first time or when the Reset command is used. This function is only called in editor.
  • addComponent Adds a component class to the node. You can also add component to node by passing in the name of the script.
  • getComponent 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.
  • getComponents Returns all components of supplied Type in the node.
  • getComponentInChildren Returns the component of supplied type in any of its children using depth first search.
  • getComponentsInChildren Returns the components of supplied type in self or any of its children using depth first search.
  • _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.
  • 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.
    If the selector is already scheduled, then the interval parameter will be updated without scheduling it again.
  • scheduleOnce Schedules a callback function that runs only once, with a delay of 0 or larger.
  • unschedule Unschedules a custom callback function.
  • unscheduleAllCallbacks unschedule all scheduled callback functions: custom callback functions, and the 'update' callback function.
    Actions are not affected by this method.
  • destroy Destroy this Object, and release all its own references to other objects.
    Actual object destruction will delayed until before rendering.
    After destroy, this CCObject is not usable any more. You can use cc.isValid(obj) to check whether the object is destroyed before accessing it.
  • _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)
  • _deserialize Init this object from the custom serialized data.

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).
    
  • 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 (event) {
    var state = event.detail;    // state instanceof cc.AnimationState
    var type = event.type;       // type === 'play';
}

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

Unregister animation event callback.

meta description
Defined in https:/github.com/cocos-creator/engine/blob/master/cocos2d/core/components/CCAnimation.js:550
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);
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.

  • 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.

meta description
Defined in https:/github.com/cocos-creator/engine/blob/master/cocos2d/core/components/CCComponent.js:426
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

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; } } }
