Particle Field

ohhhh....I've been playing!!!!!

Here is some code, just put it in frame one of your flash document...you also need to have a movie clip symbol of a circle in your library that has a class name of "Sphere".

I hope it works for you. Sorry this is a bit jumbled, I don't know how else to get the code on here. But this line...

"var p:Particle = new Particle(spm,.5,600,0,0);" the .5 is where the size parameter is.

I borrowed some stuff from a lot of different examples, this seems to work!
