Light_MinNeighbor — changes the light level in a sector to match the darkest neighboring sector.
Light_MinNeighbor (tag);
Light_MinNeighbor ( tag // Tag of affected sector );
This special's function is the same whether you activate it on a line or use it in a script.
This special instantly changes the light level in each sector matching tag to be the same as the darkest sector connected to it. If there is more than one sector matching tag, then each sector will be treated independantly from the others.
