Before you paste2

  • bAlarmActiveBoolean

    My Blueprint, then + Variable.

  • Overlap volumeBox Collision on this actor

    Add a Box Collision component and size it to the area. Its default OverlapAllDynamic preset already reports overlaps.

Good to know. Any actor sets it off, including physics props. Cast the other actor to your player class first if only the player should.

How it works

  1. Something entersActorBeginOverlap sets bAlarmActive to true and prints INTRUDER ALERT.
  2. It leavesActorEndOverlap sets bAlarmActive to false and prints All clear.
