Packagespark.effects.animation
Classpublic final class Animation
InheritanceAnimation Inheritance Object

Language Version: ActionScript 3.0
Product Version: Flex 4
Runtime Versions: Flash Player 10, AIR 1.5

The Animation class defines an animation that happens between the start and end values of a property over a specified period of time. The animation can be a change in position, such as performed by the Move effect; a change in size, as performed by the Resize effect; a change in visibility, as performed by the Fade effect; or other types of animations used by effects or run directly with the Animation class.

This class defines the timing and value parts of the animation. Other code, either in effects or in application code, associates the animation with target objects and properties, such that the animated values produced by Animation class can then be applied to target objects and properties to actually cause these objects to animate.

When defining animation effects, you typically create an instance of the Animate class, or of a subclass of Animate. This creates an Animation instance in the play() method. The Animation instance accepts start and end values, a duration, and optional parameters such as easer and interpolator objects.

The Animation object calls event listeners at the start and end of the animation, when the animation repeats, and at regular update intervals during the animation. These calls pass values which the Animation instance calculated from the start and end values and the easer and interpolator objects. These values can then be used to set property values on target objects.

Object
 Inherited
Indicates whether an instance of the Object class is in the prototype chain of the object specified as the parameter.
Object
  
Pauses the effect until the resume() method is called.
Animation
  
Start the animation.
Animation
 Inherited
Indicates whether the specified property exists and is enumerable.
Object
  
Resumes the effect after it has been paused by a call to the pause() method.
Animation
 Inherited
Sets the availability of a dynamic property for loop operations.
Object
