Changes the location towards which a previously inserted "spot light" shines in user coordinates.
key - The numeric identifier returned by a previous call to Insert_Spot_Light() . x - The new target location for the light. y - z -
Move_Light_Target() allows you to change the current specifications of a spot light's target point so that it will shine towards something new.
Move_Light_Target() does not change the light's location point. If the light was defined in "camera relative" coordinates when created, then Move_Light_Target 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.)
