I think I saw a bouncing ball sample on [http://www.bit-101.com/](http://www.bit-101.com/) I’m not sure, but you can look there if you want to know how to make a ball bounce out of actionscript or you can easily do it with simple tweens. Here’s a tutorial that shows you how using simple tweens, hope that is what you’re looking for. =) [http://www.acky.net/tutorials/flash/bouncing\_ball/](http://www.acky.net/tutorials/flash/bouncing_ball/) ---
