I'm working on a preloader, which is a movie clip which is
100 frames long. I've got an animation of a line spinning a circle
like a minute hand on a clock. I'd like to have wherever the line
travels to draw and fill in the same color as the line. I could
spend the time to make a mask and a fill, but I thought that maybe
with actionscript or something there was a way to have the line
just "draw" over wherever it travels.
If you draw the line with ActionScript, you will know where
the end points are, allowing you to draw a series of rectangles as
the line moves. If the line has been tweened along a timeline, you
could still get the bounds of the movieclip containing the line and
do the same thing.
