How to get vaiables from dynamical array of different actors?

Hello everyone! It’s a problem stunning me a few days… I have an array of actors that could be modified in-game. All of this actors have one variable containing specific structured data of themselves. So this doesn’t work as I imagine (see image)

I suppose I can’t get this variable without casting to each of them because this variable wasn’t created in parent class (actor)… Is where way to fo it? Or maybe I should use another data container?

Meshes to spawn is array of “class actor” type.

Why don’t you create common ItemInfo and put it in parent?

Thats my question) How?
And will it keep data of every child class then?

I can only create new ParentTestBox Class and all my child spawn actors will have all parent variables. Good enough…
