Outputs
- OnDissolve
- Fired whenever an entity is dissolved by the trigger.
- OnDissolveBox
- Fired when a box is dissolved by the trigger.
Note:in order for this output to fire, the object it dissolves must have the world model "models/props/metal_box.mdl"
- OnFizzle
- Fired whenever portals are fizzled by 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 )
