Motion

(Beta)

Package	fl.motion
Class	public class Motion
Inheritance	Motion MotionBase Object

Language Version:

ActionScript 3.0

Product Version:

Flash CS3

Runtime Versions:

Flash Player 9.0.28.0, AIR 1.0

The Motion class stores a keyframe animation sequence that can be applied to a visual object. The animation data includes position, scale, rotation, skew, color, filters, and easing. The Motion class has methods for retrieving data at specific points in time, and interpolating values between keyframes automatically.

Note: In Flash CS3, many of the properties and methods supported by this class were members of this class, exclusively. Flash CS4 introduced a base class, KeyframeBase, for those properties and methods of this class, and they are now shared by other classes through the inheritance chain. If you have been working in Flash CS3, notice that these properties and methods are still supported by the Keyframe class, but are members of the KeyframeBase class in releases of Flash Professional after Flash CS3. As with any other class in this reference, select Show Inherited Public Properties and Show Inherited Public Methods to see all of the properties and methods supported by this class.

	Property		Defined By
		constructor : Object A reference to the class object or constructor function for a given object instance.	Object
		duration : int Controls the Motion instance's length of time, measured in frames.	MotionBase
		is3D : Boolean Specifies whether the motion contains 3D property changes.	MotionBase
		keyframes : Array An array of keyframes that define the motion's behavior over time.	MotionBase
		keyframesCompact : Array A compact array of keyframes, where each index is occupied by a keyframe.	Motion
		source : Source An object that stores information about the context in which the motion was created, such as frame rate, dimensions, transformation point, and initial position, scale, rotation, and skew.	Motion
