How to get the same variable from different actors?

I am trying to make a game with Zombies (I know im so original) and part of the gameplay is that zombies are attracted to the object with the highest energy level. I wont get into too much detail, energy acts like light, and so what I want to do is have a zombie AI search for whatever actor has the highest energy level and move to it. Is there a way I can grab the same-named variable from multiple actors at once and have the Zombie chase the highest number?

You can also use an actor component that you attach to any object you want to track and use get component when iterating actors. That way, you’re not confined to using a cast or a handful of actors to cast.
