Well my thinking is if not Boolean, the current setup has each pawn spawning an actor and holding a reference, so whether its a Boolean or a skill reference, one way or anther there is going to be a huge list of skills. Unless I can think of a bit flag and corresponding map on a single variable, but I haven’t had to think in binary and how that might work in Unreal yet.
Don’t think it gets any smaller then a bit flag, but its still the same principle, maybe just less memory though.
