Static linedef specials
From Eternity Wiki
Jump to navigationJump to search
Static linedef specials are actions which are run at level start-up. They're not activated during the game, unless otherwise noted (some static specials can actually be activated dynamically, but only from ACS) They're placed on linedefs and can have up to 5 parameters. Under the Doom format, the linedef tag doubles as the first parameter, and if it's parameterized, it requires ExtraData.
