I’m trying to get this little length of animation to reveal other parts of the swf that it passes over. Like say, in the attached file, I want the shape that rotates once around the center to leave behind the same colour so that the end result would be a full page of colour. Does anyone have any idea how to do that? Thanks in advance.
