[Flashcoders] Erasing areas with the drawing API?
Does anyone know how to erase part of an area that was created with the drawing API? I need to be able to draw a polygon, and then draw another polygon inside it and punch it out. For example, I need to draw a square and then punch a square hole in it. Anyone ever done this before?

Yes -- draw the second (inner) shape before you do the endFill and it will be punched out. If you need the final shape to be a mask, draw the inner shape in the reverse direction from how you drew the outer shape (ie, counter-clockwise if the original shape was drawn clockwise). http://flash-creations.com/notes/dynamic_drawingapi.php at the bottom of the page Helen -- http://flash-creations.com http://i-technica.com David Ham wrote: Does anyone know how to erase part of an area that was created with the drawing API?

Re: [Flashcoders] Erasing areas with the drawing API?
Huh, that was easy. Turns out that if you don't call endFill(), you can just draw the polygon, moveTo() the hole, and lineTo() the outline of the hole, and it fills itself in. I found an example of this in this article: http://www.adobe.com/devnet/flash/articles/adv_draw_methods.html Specifically in the drawGear() example.
