Changes the location, in object space, of a previously inserted "local light" or "spot light".
key - The numeric identifier returned by a previous call to Insert_Local_Light() or Insert_Spot_Light() . x - The new x-location for the light. y - The new y-location for the light. z - The new z-location for the light.
Move_Light_Position() allows you to change the current specifications of a light's position so that it will shine from somewhere new.
When applied to a spotlight, Move_Light_Position() does not change the light's target point. In addition, if the spotlight was defined in "camera relative" coordinates when created, then Move_Light_Position() will also be in camera relative coordinates.
If you define the light in a segment of its own, you can also move it around relative to its previous location by calling modelling transformations like Rotate_Object() and Translate_Object() . (The "object", in this case, is the light.)
