Trigger hierarchy

trigger_hierarchy is an e2 available in Portal 2.

Entity description

A trigger volume that can will check if any of trigger's children pass a secondary filter.

Keyvalues

Child Filter Name ([todo internal name (i)]) <filter>

Filter to use to see if activator's children trigger me. See filter_activator_name for more explanation.

Delay Before Reset ([todo internal name (i)]) <integer>

Amount of time, in seconds, after the trigger_multiple has triggered before it can be triggered again. If set to -1, it will never trigger again (in which case you should just use a trigger_once).

Inputs

TouchTest

Tests if the trigger is being touched and fires an output based on whether the value is true or false.

Outputs

OnTrigger

Fired whenever the trigger is activated.

OnTouching

Fired when the TestTouch input is true (something is touching the trigger.)

OnNotTouching

Fired when the TestTouch input is not true (nothing is touching the trigger.)

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.
