You can't move a surface. You can render the surface on another surface (generally the backbuffer) in different locations. For this, you'll need some sort of geometry since directx 8 doesn't support a bitblt. You will need to create a "quad" that uses the surface as a texture. You then modify the World matrix by either creating a translation matrix as the world matrix or multiplying the current world matrix with a translation matrix. |

no, i really mean surface -- Direct3DSurface8 object |
