Hi @GlacierFox
Im not sure if there is a way to manipulate some sort of on click event like in a player controller? that would negate the use of the tick event which can be costly, but also not, dont be scared to use on tick, too many people tell you to stay away, but sometimes its the only or best way. All depends on the impact!
Anyway not sure if there is an editor version of onclick event but would be the best way if there was!
May or may not be relevant and not sure if you using c++
