animCtrl.play("linear");

playAdditive

:

// linear_1 and linear_2 at the same time playing.
var animCtrl = this.node.getComponent(cc.Animation);
animCtrl.playAdditive("linear_1");
animCtrl.playAdditive("linear_2");

stop

getAnimationState
(

addClip
(

clip AnimationClip

newName optional String

:

: AnimationState

The AnimationState which gives full control over the animation clip.

removeClip
(
  • clip
  • force
)

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

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.

on
(
  • type
  • callback
  • target
  • useCapture
)

Register animation event callback. The event argumetns 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.

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).

  • param Event

    event

    • type String

      The name of the event (case-sensitive), e.g. "click", "fire", or "submit"

    • bubbles Boolean

      A boolean indicating whether the event bubbles up through the tree or not

target Object

The target 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.

:

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
(
  • type
  • callback
  • target
  • useCapture
)

Unregister animation event callback.

type String

A string representing the event type being removed.

callback Function

The callback to remove.

target Object

The target 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.

:

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