Inputs

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.

Outputs

OnPlayersIn

Fired when the player count passes the requirement.

OnPlayersOut

Fired when the player count drops below the requirement after reaching it.

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.
