Light_ChangeToValue — sets the light level in a sector.
Light_ChangeToValue (tag, amount);
Light_ChangeToValue ( tag, // Tag of affected sector amount // New light level );
This special's function is the same whether you activate it on a line or use it in a script.
This special changes the light level instantly. If you want to change the light gradually over a period of time, you should use Light_Fade instead.
