Linedef type 304

Jump to: navigation, search

Linedef type 304, Ring Count – Once, is a type of linedef executor trigger which activates any linedef executor in the control sector when a player activates a tagged trigger sector. Unlike linedef type 303, the linedef executor can only be triggered once, and then will not be triggered again until the map is reloaded.


The amount of rings an activating player is required to have to trigger this effect is determined by the length of the controlling linedef. Without any linedef flags, the number of rings must be exactly equal to the length of the controlling linedef. If the Block Enemies flag is checked, the required number of rings must be greater or equal than the length of the controlling linedef. If the Not Climbable flag is checked, the required number of rings must be less or equal than the length of the controlling linedef. If the Solid Midtexture flag is checked, the linedef will consider the ring count of every player, rather than the ring count of the activating player.


Example WAD: ex_ld304_trigger_ringcountonce.wad
  • This example WAD can be played in any gametype. It uses MAP01, replacing Greenflower Zone Act 1.
  • If the player enters the elevated sector with 32 rings, they will receive 100 points. Entering the sector again will not give the player any more points.
