jeroen: your idea, iirc, will only work if the character texture is applied with the mask flag. Im sure he doesn't want a black hole there, he wants a hole. You cant change the alpha of textures in blitz (that I know of) so you'd have to apply the character texture with the mask flag, and draw on a black oval possibly.
With jfk's way.. thats going to results in a black dot again, not a hole. Unless... the sprite is textured by doing a copyrect at the bullet impact point, onto the sprites texture. Although with this way you'l need to update every bullet hole every loop - that's slow!
A true bullet hole would need some CSG operations - well just one. There is code in the code archives explaining and demonstrating this :) Have fun ^_^
