I need to pass a pixel (and it''s color) to an array from a surface. How do I do that?

Use IDirect3DSurface8::LockRect.

---visit #directxdev on afternet <- not just for directx, despite the name

If you know the x and y cords then use GetLockedPixel to return the colour, just make sure to lock/unlock the surface.

eg.

  Surface.lockArray[x][y]=Surface.GetLockedPixel(x,y);Surface.unlock

in Psudocode.
