Set variable on utility widget

[Lunder]

Hi,
Can we set a variable from an Utility Widget event?

I have an boolean on an actor that I set to true when I click on a button in my Utility widget, that change it in the editor but when I launch the game it works litteraly once in two times and when I close the game the boolean value become the default value again.

So how can I set a varaible on an actor already on the map using an utility widget, the particularity here is that the actor is a child actor.

here the code in the widget :

We stopped using ChildActors as they are broken as f… as of 4.16. Dunno if they fixed anything about them. Spawn the class you want in BeginPlay and attach it to where you want it.
