Hey, I’m still trying to make a ball bounce realistic.
Check the swf and see what I’ve done so far. It’s quite realistic,
but not 100%. It can roll, as you can see, but… you will see what’s unrealistic if you change the ground.
Do any one wanna help me make it realistic? And, I know about vectors,
and I don’t wanna use it, I wanna make it with ang’s and hitTest, because then you can draw the ground as you want directly in flash. With vectors you gotta draw it with AS, and that’s alot of work. 
So, take a look at the file and see if you can help me! 
… woot, couldn’t upload the swf… well, just open the fla.
