Description
Method; instructs the tweened animation to play in reverse from its last direction of tweened
property increments. If this method is called before a Tween object's animation is complete,
the animation abruptly jumps to the end of its play and then plays in a reverse direction from
that point. You can achieve an effect of an animation completing its entire play and then
reversing its entire play by calling the
Tween.onMotionFinished
Tween.yoyo method does not begin until the current tweened animation is complete. See
Tween.onMotionFinished
Example

import mx.transitions.Tween;
var myTween:Tween = new Tween(img1_mc, "_x",
mx.transitions.easing.None.easeNone,0, Stage.width, 4, true);
myTween.onMotionFinished = function() {
myTween.yoyo();
