trigger_multiple is a brush entity available in all Source games. It is a volume that fires outputs when a specified type of entity enters or leaves it.

Keyvalues

Name (targetname) <string>

The name that other entities refer to this entity by, via Inputs/Outputs or other keyvalues (e.g. parentname or target).
Also displayed in Hammer's 2D views and Entity Report.

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 OnEndTouch output, but when player is revived OnStartTouch output won't be fired and also using vscript function trigger.IsTouching(player) will return false for the given player. The behaviour when Entire Team Number is picked differs. When player is incapacitated OnEndTouch output is NOT fired and player is considered still touching the trigger so this bug won't occur in such case.   [todo tested in?]

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 theEnableinput).

StartTouch  (in all games since ) !FGD Behave as if the !caller entity had just entered the trigger volume. Accepts non-physical entities. EndTouch  (in all games since ) !FGD Behave as if !caller had just exited the trigger volume.

BaseTrigger

OnStartTouch Fired when a valid entity starts touching this trigger. !activator is whatever touches the trigger. Bug:Spamming crouch jumps in a trigger can randomly fire OnStartTouch. Confirm:Is it a Multiplayer issue only?   [todo tested in?] OnStartTouchAll Fired when a valid entity starts touching this trigger, and no other entities are touching it. If there are any other entities touching the trigger when a new one begins to touch, only OnStartTouch will fire. OnEndTouch Fired when a valid entity stops touching this trigger. Warning:This includes entities which are deleted while inside the trigger. In this case !activator will be invalid. Warning:OnEndTouch can fire before OnStartTouch under certain circumstances where both are fired on the same tick and each have the same delay. Fix:Add a slight delay to OnEndTouch. Bug:Spamming crouch jump in a trigger can randomly fire OnEndTouch. Confirm:Is it a Multiplayer issue only?   [todo tested in?] OnEndTouchAll Fired when all valid entities stop touching this trigger. OnTouching  (in all games since ) Fired if something is currently touching this trigger when TouchTest is fired.
