Transfer_FloorLight — changes the floor light level in a sector
Transfer_FloorLight (tag);
Transfer_FloorLight ( tag // Sector(s) to change the floor light in );
This special must be placed on a line, and it is only valid when the level is loaded. You cannot use ACS to place it on a line or remove it from a line during gameplay.
ZDoom actually maintains separate floor and ceiling light levels for each sector. You can see this if you load a BUILD map that has different floor and ceiling shades in a single sector.
Because the Doom/Hexen map format does not allow for setting these light levels directly, you need to use this special to make the floor's light level different from the sector's main light level.
Make any sectors with tag 5 use the same light level as the sector in front of this line for their floors:
Transfer_FloorLight (5);
