I am making a movie using AS for an intro flash movie. The movie includes rectangles that simply move downwards with random speed, height, and width.
My question is how I could change the color or alpha of the overlapping areas as seen in the quick sample I made and attached.
I have gotten some success from making the MC’s with an alpha and when they overlap there is a more solid color but it isn’t quite the effect I was looking for.
