OnTriggerActor
From The Elder Scrolls Construction Set Wiki
Syntax:
begin OnTriggerActor TriggeringRefID
Example:
begin OnTriggerActor player
This block will be run once when an actor triggers the scripted object by colliding with it. If you specify a TriggeringRefID, the block will only run when that specific reference triggers the object (assuming the reference is an actor); otherwise, the block will run when any actor triggers the scripted object.
