I just started using SDL today. I am able to make an image move on the screen, but I can''t figure out how to set the transparency using this statement: SDL_SetColorKey(surface, SDL_SRCCOLORKEY, SDL_MapRGB(surface->format, r, g, b)); I want to make it so green 255 is transparent, but I can''t figure out what to do with the surface->format statement. Can anyone help me out? Thanks in advance

Please read the FAQ, particularly the section on cross posting. Anyway, the anonymous poster in the Graphics forum gave you the right advice:

SDL_SetColorKey(surface, SDL_SRCCOLORKEY, SDL_MapRGB(surface->format,0,255 ,0));
