I was wondering if there was a way to make SDL_FillRect() semitransparent so that I can highlight the image behind it, anyone know of a way?

You need to blit an image that is transparent to do that. SDL_FillRect has no built in funcitonality to do transparency. If its a set size that you want to highlight, you can just make an image that size and blit it over the object to highlight it. If its not a set size, there are other ways. Just ask if thats the case.

well, you could do SDL_FillRect for a slightly larger size BEFORE blitting the image. This would have the same effect as a separate surface with a large colorkeyed section, and may have better performance.
