Action Specials - ZDoom Reference

Action Specials

DOOM mode

In DOOM mode, a linedef's special can be any of the specials supported by BOOM. Go see boomref.txt for a list of those. The following three linedef types are also supported to set some sector properties:

333: The line's length sets the tagged sector's gravity, where 100 units is normal gravity, 200 is double gravity, 50 is half gravity, etc.
334: Sets the light or fog color of the tagged sector. The line's upper "texture" sets the sector's light color, and the lower "texture" sets the sector's fog color. These are both hex numbers of the form "RRGGBB" rather than actual texture names.
335: Sets the tagged sector's damage level, where the length of the line determines how much damage is done while the player stands in the sector.
