Thanks for the good tips. Actually this is an extended example of the FriendsOfED-foundation as3-animation. I was trying to use the same kind of coding as the author has (not very successful i think). The balls are simple black circles, with a a glow effect on it. And the position of the ball changes all the time, as well as the color of the glow. The motion is actually simple springing. The springing target changes every 1 s (or .5), so the balls spring towards the target. I found out that it forks much slower, if the new target point is very far away from the old one (looks like AS3 has still many problems with calculation higher values). I prefer to stop talking, as you can see it by your own. Here's a ZIP of it, if you couldn't download the files separately. http://www.humyo.com/F/2000999-218668805 (you don't have to register to download it).
As the color of the glow is defined by a Math.random()*color function. Would it maybe be faster to enter some values of colors in an array and them chose one of them, instead of calculation a new random each time? Any more help appreciated. *Pedro D.
