Hi everyone! I''m thinking about the collison detection for my game and I wonder if it''s possible to get the color of a pixel from my surface (lpddsprimary) and return it as a RGB-value or as a hexadecimal color value. // kp

Yes it is possible, dont ask me how though, but you really dont want to do that, reading from videomemory is very slow
Collision Detection is usually a two-step process. A larger stage where you have a virtual box(bounding box) around the sprite and compare it to other bounding boxes to see if they overlap. 95% of the time you can do this quick check and it should suffice.
Or you could have a spite with 2 or more bounding boxes.
How accurate do you need it ?? Because in any furious action the user''s not going to notice TOO much.
Are we talking 3D or 2D??
