Help: jumping object

i got problem to create a elastic ball, my friend said it can be created by “frame by frame” method or write action script (use math calculation)

i confuse about it, how the math calculation done actually?
anyone know it?

I think I saw a bouncing ball sample on 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. =)

yup, that is wut I mention but still got little bit different with my expected (the jumping ball would slowly jump lower at each level).
i think i can handle it

anyway, very appreciate for ur help:beam:
