I was watching this video, which is very interesting http://www.youtube.com/watch?v=Fy0aCDmgnxg
At about minute 4 in the video they show this formula I have in the title. How would this be translated to an event in MMF? Many of these effects are very cool, especially the one where the ball hits the walls and they "bounch" on the impact. I wonder how these could be translated to mmf code.
