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.

Outputs

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.
