i always get a reference to my character with GetPlayerCharacter but how do I get access to other characters?

You could use an array, and then work with it in the level blueprint or something. That would allow you to make a system like FF7 Remake.

i’ve been using get actor of class so far but since they are expensive to use im looking for a better way.

the character is an ai which is patrolling around and the ai is not supposed to interact with anything. is there seriously no other way to get a reference to it other than using get actor of class?
