Does anyone know how the game detects when the player collides with another actor? Like when you're invisible and have the Muffle effect, it's impossible for you to be detected without touching your enemy. Is this done with a separate event or is this done in a cheap way by using a function like http://www.creationkit.com/FindClosestActorFromRef_-_Game() in an OnUpdate() event?

I can use that method but I'd still like to know if there is such an event.
