Hey guys, I’m a self proclaimed n00b when it comes to as3, but I’m learning rapidly. I followed this guide and created a great particle system: http://www.actionscript.org/resources/articles/607/1/A-simple-particle-system-using-Actionscript-3/Page1.html
What I’d LIKE to do, if possible, is make those particles that are generated be the only part of an image that shows(mask). The tutorial contains a fla with a movieclip of a circle, two classes…particle and ball which call the movieclip and generate it on the stage.
Any help would be greatly appreciated
