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?

Make a parent blueprint (i.e. EnergyBasedActor) that has the variable you want to be shared across your actors. Then make your actors that you want to have that shared variable a child blueprint of EnergyBasedActor. Then from your ZombieAI, do a*GetAllActorsOfClass* node of EnergyBasedActor and then get one with the highest. That way no matter what actor it is as long as it is a child of EnergyBasedActor, you can get their shared variable.

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.
