I work with UE4 blueprint and I want a way with to make an event run if the player got inside a circle for 15 seconds, if the player left the circle before 15 seconds nothing will happen, but if the player went back inside the circle they should wait for 15 seconds to run the event.

Enter circle → start a 15s timer
Leave circle → invalidate timer
