I set my display mode in direct draw to:
dd.SetDisplayMode 1024, 768, 32, 0, DDSDM_DEFAULT
But when I blit, there are weird pictures or "sprite trails" showing up in parts of the screen, but this does not happen if I set it to 16-bit, then again I dont want to use 16 bit, so anyone know how to fix this problem?
thanx........
Without seeing exactly what you're doing there's not much we can do to help you.
ok........................
this is the code for the game for now....when I display my image, I have weird pictures or "sprite trails" while in 32 bit for display mode. But Works fine in 16 bit. Problem?
