Please! A simple Blueprint Interface example.

I’ve tried a lot, but just can’t get the Blueprint Interface to work for me.

Could someone PLEASE just give a very simple Blueprint Interface example?

A cube, and a sphere.

Get a variable from one to the other using only the Blueprint Interface.

To start:

Drag in a cube and a sphere.

Add Blueprint to the sphere actor.
Add Blueprint to the cube actor.
Create a Blueprint Interface.

Add interface via Class Settings to cube and sphere.

Now, how to pass a variable between them?

Thank you so much for any help!

Not entirely sure but in video #3 (or other) here the author uses a interface, and shows how to integrate it
