Keyvalues
Targetname:
- Name
(targetname)<string> - The targetname that other entities refer to this entity by.
- Delay Before Reset
(wait)<float> - Delay in seconds before OnTrigger can fire again, 0 defaults to 0.2. If set to -1, it will kill itself when triggered (as trigger_once), which means outputs like OnEntireTeamStartTouch can never fire.
- Entire Team Number
(entireteam)<choices> (only in
) - If the entire team is touching, fire OnEntireTeamStartTouch.
- 0 : None
- 2 : Survivor
- 3 : Infected
- Incapacitated players can trigger
(allowincap)<boolean> (only in) - Whether incapacitated players can trigger.
Bug:When 0 and player is incapacitated in the trigger it correctly fires OnEndTouchoutput, but when player is revived OnStartTouch output won't be fired and also using vscript functiontrigger.IsTouching(player)will return false for the given player. The behaviour when Entire Team Number is picked differs. When player is incapacitatedOnEndTouchoutput is NOT fired and player is considered still touching the trigger so this bug won't occur in such case.
- Ghost players can trigger
(allowghost)<boolean> (only in) - Whether ghost survivors can trigger.
BaseTrigger:
- Filter Name
(filtername)<filter> - A filter entity to test potential activators against.
- Start Disabled
(StartDisabled)<boolean> - Stay dormant until activated (with the
Enableinput).
