trigger_multiple is an e2 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>[ Edit ]: 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. See also: Generic Keyvalues, Inputs and Outputs available to all entities

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.

Incapacitated players can trigger (allowincap) <boolean> (only in ): Whether incapacitated players can trigger.

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`Enable`input).

BaseTrigger
Everything (not including physics debris) `: [64]` Clients (Survivors, Special Infected, Tanks ) `: [1]` Only clients in vehicles `: [32]` Only clients not in vehicles `: [512]` Disallow Bots (removed since ) `: [4096]` NPCs (Common Infected, Witches ) `: [2]` Only player ally NPCs `: [16]` Only NPCs in vehicles (respects player ally flag) `: [2048]` Physics Objects (not including physics debris) `: [8]` Physics debris (include also physics debris) `: [1024]` ~~Pushables (Passes entities with classname `func_pushable`) `: [4]`~~ Deprecated. Equivalent to using Everything + `filter_activator_class` that filters `func_pushable`.

BaseTrigger
`Toggle` Toggles this trigger between enabled and disabled states. `Enable` Enable trigger `Disable` Disable trigger `TouchTest` (in all games since ) Triggers either the `OnTouching` or `OnNotTouching` outputs for whether anything is touching this entity. Bug:Sleeping prop_physics will never fire "OnTouching". Also applies to entities using prop_physics as base. (tested in: ) `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. `DisableAndEndTouch` (only in ) Disables this trigger and calls `EndTouch` on all currently-touching entities.

StrataEngine:

Touch (only in Strata Source games): Behaves as if !caller has touched the trigger volume

OnEntireTeamStartTouch (in all games since ): Fired when an entire team starts touching the trigger.

OnEntireTeamEndTouch (in all games since ): Fired when an entire team stops touching the trigger.

OnTrigger: Fired repeatedly with a delay while an entity is within this trigger's volume. Delay is defined by Delay Before Reset key.

BaseTrigger
`OnStartTouch` `!activator` = entity that caused this output `!caller =` this entity Fired when a valid entity starts touching this trigger. `OnStartTouchAll` `!activator` = entity that caused this output `!caller =` this entity 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` `!activator` = entity that caused this output `!caller =` this entity Fired when a valid entity stops touching this trigger. Note:Will also fire for entities touching it when trigger is disabled via `Disable` input 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^[How?] where both are fired on the same tick and each have the same delay. Fix:Add a slight delay to `OnEndTouch`. `OnEndTouchAll` `!activator` = entity that caused this output `!caller =` this entity Fired when all valid entities stop touching this trigger. `OnTouching` (in all games since ) `!activator = !caller =` this entity Fired if something is currently touching this trigger when `TouchTest` is fired. `OnNotTouching` (in all games since ) `!activator = !caller =` this entity Fired if nothing is currently touching this trigger when `TouchTest` is fired.
