Member Function Documentation

BeginDestroy()

void UTriggerZone::BeginDestroy ( )

overridevirtual

Cleans up component before destruction.

Removes collision event bindings to prevent crashes

Parameters

OverlappedComp	The component that was overlapped
OtherActor	The actor that entered the zone
OtherComp	The component of the entering actor
OtherBodyIndex	Body index of the collision
bFromSweep	Whether this was from a sweep operation
SweepResult	Hit result from sweep if applicable
