I'd probably just determine the points ahead of time and recreate it using AS...
Most likely, that would be less time consuming. That's my answer if this is a practical question, if it's theoretical and you just want to know if it can be done, I'm sure it can, but I'm not totally sure which method to use to achieve the desired result. - Taka On Mon, Feb 9, 2009 at 11:56 AM, Mark Winterhalder <mar...@gmail.com> wrote: > On Mon, Feb 9, 2009 at 7:47 PM, Todd Kerpelman <t...@kerp.net> wrote: > > Hey, coders! > > > > I have a Sprite that consists of a polygon that I drew in Flash (using > the > > line tool) and saved into my Library. > > > > Using ActionScript, is there any way to easily find the points of said > > polygon?
