Language Version: ActionScript 3.0
Runtime Versions: AIR 1.0 Flash Player 9.0.28.0

The Animator class applies an XML description of a motion tween to a display object. The properties and methods of the Animator class control the playback of the motion, and Flash Player broadcasts events in response to changes in the motion's status. If there isn't any three-dimensional content, the Copy Motion as ActionScript command in Flash CS4 uses the Animator class. For three-dimensional content, the Animator3D class is used, instead, which shares the same base class as the Animator class but is specifically for three-dimensional content. You can then edit the ActionScript using the application programming interface (API) or construct your own custom animation.

If you plan to call methods of the Animator class within a function, declare the Animator instance outside of the function so the scope of the object is not restricted to the function itself. If you declare the instance within a function, Flash Player deletes the Animator instance at the end of the function as part of Flash Player's routine "garbage collection" and the target object will not animate.
