IKMover

(Beta)

Package	fl.ik
Class	public class IKMover
Inheritance	IKMover EventDispatcher Object

Language Version:

ActionScript 3.0

Product Version:

Flash CS4

Runtime Versions:

Flash Player 10, AIR 1.5

The IKMover class initiates and controls the inverse kinematic (IK) movement of armatures. Use the IKMover class to move the IKJoint object to the target point unless the IKMover object determines that the point can't be reached because of the established IKArmature constraints; or if the movement exceeds established timeLimit, iterationLimit or distanceLimit values.

	`endEffector:IKJoint` — The IKJoint object to move.

	`targetIn:Point` — The starting coordinates for the movement. This point is similar to a point on the stage of the Flash authoring tool where you can click on a symbol that is part of an IKArmature object (not necessarily on a joint), move the symbol, and consequently move the IKArmature object according to the constraints established for the IKArmature object. For example, you have a leg and a foot, and you want to move the foot from the toe. If you specify a `targetIn` point at the toe of the foot, you can move the foot from that point. Otherwise, you would have to create a symbol at the toe to connect the toe to a bone before you could move the foot.
