I would also like some parts of these sprites to be transparent so the background is visible through them. There is an allegro function masked_blit to do this, but it doesn't seem to work.....any points of colour 0 on my sprites simply show up as black on my background, NOT transparent. Ideas ? Ta, Chris.
