Point/click pixel-based collision with transparent pngs

programming

Hi

I’m making a simple boardgame type thing. I need to know if there is a simple way (using hitTest) to get Flash to recognize my transparent png’s “alpha=0” pixels as being empty (therefore, not registering a collision with these).

NOTE, I don’t need to know anything about sprite-to-sprite collision detection. This is literally pixel-to-sprite only, i.e. I need to detect a single-point mouseclick on an irregular bitmap.

PS Do I HAVE TO use shapeFlag? If so, how.

Thanks very much in advance.

EDIT: Problem solved here as pointed out by Odysseus elsewhere.
