How do I create a Boolean list / index / array to track the recent player character that enters my Trigger Box on ComponentBeginOverlap?

not really true because they go hand in hand, so you just put the interface on the parent, same result but now it works for everything in the game.

Placing the component in the parent is inheritance. We’re actually saying the same thing . Inheritance has nothing to do with communication between blueprints.
I think when you say inheritance, you mean casting and abstract classes I guess, and I misunderstood.
Moving from casting to interface is very easy, and I prefer to leave it for when the game is already in the polishing phase or because they are too lazy for the cast to especially the things of the gamemode and gamestate

But yes, of course, it is still a personal choice.
