Yes there are a couple today :p Needless to say i am trying to design a game engine. Ok so heres the question For example im just updating soem direct Draw code i made and im testing it i have an image the follows the cursor on the screen but when you get to going slight off the screen with the image it dissapers. How would one go about making it so even if the image is off the screen partly it will still show whatever is still on the screen. -.^ i have double buffering setup and some basic i will post code if needed. Regards Joeui.

You must create a DirectDrawClipper and attach it to the surface you're blitting to (usuallly the backbuffer), or do the clipping yourself if you're using BltFast. There's not much to it, you should be able to set it up easily from the docs.

Seems DirectDraw is regaining popularity lately :)
