Other Triggers

Please note that the exit to a secret level only works from the same levels as the regular game. Regular and extended lighting triggers are:

Last but not least, some regular and extended 'DONUT' linedefs. From BOOMREF.TXT: "A donut is a very specialized linedef type that lowers a pillar in a surrounding pool, while raising the pool and changing its texture and type. The tagged sector is the pillar, and its lowest numbered line must be two-sided. The sector on the other side of that is the pool. The pool must have a two-sided line whose second sidedef does not adjoin the pillar, and the sector on the second side of the lowest numbered such linedef is the model for the pool's texture change. The model sector floor also provides the destination height both for lowering the pillar and raising the pool."
