Create 4 copys of the actor with a triggerbox (or connect to something else, but use the triggerbox -> event begin actor overlap for testing, add the real trigger when everything else is working) and with the Booleans “Statue[ID]_done”, or something like this. Replace [ID] with a number, for example 1-4. In the level Blueprint or another actorBP or whatever get all Booleans, create the AND nodes and then set every tick the Boolean “DoorIsOpen” to the result. Now you can access the boolean and check every tick in your DoorBP if it´s true and then open/close. If you couldn´t understand it, i can make it and show you the screenshots. Sirry for my bad english
