StartTouch  (in all games since ) !FGD

Behave as if the !caller entity had just entered the trigger volume. Accepts non-physical entities.

Behave as if !caller had just exited the trigger volume.

Outputs

• {| class="mw-collapsible mw-collapsed" style="background:initial;float:no;margin-bottom:1em;margin-left:0;padding-right:0.5em;border:1px solid rgba(255,255,255,0.1); border-left:solid 1px #8bb9e0; padding-left:1em;"

|+ style="text-align:left; white-space:nowrap; font-weight:bold; color:#ddd; " | 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.
