    bitblt runing real slow

    i have recently figured out how to use bitblt, and i made a game with it, right now its nothing but a character moving on a screen, this is because it runs REAL slow, if i press down, it takes about 7 seconds to move down. It was runing smoothely yesterday, but when i started it today, it ran real slow. Any help on making it run smoother?

    Are you using TransparentBlt by any chance? It is a huge memory hog. Restart your computer and see if that helps, if not.

    (Just a heads-up)

    bitblt shouldnt be running slow at all, perhaps you done some bad code design?

    paste your code ( if it aint too big ), someone might be able to see whats wrong

    You're probably passing it bad parameters. Just because your image is clipped when it's copied doesn't mean it won't slow down the blit. if you try and copy a 1280x1024 image onto a 640x480 screen, it'll be slower than explicitly copying a 640x480 piece.
