All konw。TweenMax带来了很多方便，也节省了我们很多的时间。下边给出一个效果，将一组显示对象丢出舞台或丢回舞台。

该想法来自于《完美世界射雕zero》印象站。

思路是：随机出一定范围的x坐标，y坐标，旋转角度。然后，随机这些现实对象的延长时间。这个所谓的延长时间，是TweenMax自己处理的。我们只要给出就行。再加一些透明度，缩放。

最后，用一个for循环TweenMax所有你想丢的显示对象。

先看效果，请拿起你的小小手，点击舞台吧。

这里，仅仅是给出的随机颜色的小方块。如果项目中，可以是图片也可以是其他比较好看的小对象。也不一定非要那么整齐，大小一致。位置等。自己发挥。

好啦，下边贴出完整代码。供参考。
