Look-at vector?

If you want to move an object in world space, apply a world translation. D3DXMatrixTranslation() will do the trick. Set that to the world matrix, and it''ll move.

the lookat vector from your position (yourPos) to another position (theirPos) is simply theirPos - yourPos and then normalize the vector.
