How can i have an event or function that fires when an actor begins existing at design time?

[harsh jasper]

I need to have an event or function in an actor that fires when said actor begins existing, but at design time rather than runtime, this is because I'm trying to make my life easier when it comes to creating levels for my game, which in my case involves a lot of intercommunication between the different actors that make up the "level" so im trying to have the actors automatically register each other when i drop them in the level.

so far i have tried using the construction script, but it fires constantly which is not ideal as i will be performing expensive operations such as get all actors of class and such. The construction script also seems to not respect the gate node or the do once node, so i have no idea how to get this sort of event or function that fires just once when the actor is placed at design time

You can make editor callable events in blueprint, look it up. I have to say "making my life easier" and "a lot of intercommunication" hardly go well together, you could explain what you trying to achieve, maybe theres better ways
