چگونه motion را کند کنم

 
 
import fl.motion.Motion;
import fl.motion.MotionBase;
import fl.motion.AnimatorFactory;
import flash.geom.Point;
import flash.events.Event;
 
 
var motion: MotionBase;
 
 
if (motion == null) {
        motion = new Motion();
        motion.duration = 200;
 
        // Motion array 
        motion.addPropertyArray("x", [0, 30, 50, 80, 120, 150, 200, 250, 300, 350, 400]);
        motion.addPropertyArray("y", [0, 30, 50, 80, 100, 120, 140, 160, 180, 180, 160]);
 
 
        var animFactory: AnimatorFactory = new AnimatorFactory(motion);
        animFactory.addTarget(mc);
}
