Hi, i'm not sure if this is the best forum to post this question but i'm gonna give it a try. I would like to be able to figure out a formula from a given graph( http://img46.imageshack.us/img46/8172/graphun4.jpg [Broken] ). basically that would be the motion of a bouncing ball. Ultimately what i would like to do is figure out how to simulate those kind of motions into flash via action script to build bouncing windows, drop down menues etc. I guess i can go and do some research on snippets and copy past but i'd rather try to understand it how it works :P. thank you in advance.
