What I am doing is in a c++ class I am broadcasting an event, and I want to “catch” it and act.
In my case, on my MyCharacter class, I have an inventory and I wanted to display this in a widget blueprint. This seems on the surface to be simple … like ye olde “health bar update”. I’m missing something, but I can’t seem to nail down what it is.
Any help would be appreciated.

What I would have liked/expected was that I could catch the event in the blueprint and then do what I needed to do. In this case I was just attempting to log them. I can definitely verify that the event broadcast is being called. In this case I’m not able to catch.
I have reviewed this which seemed on the surface to be what I wanted. But it doesn’t seem to work.
