I’ve watched the twitch stream several times, but I didn’t see any examples of communicating outside the widget itself to trigger custom events in the Level Blueprint. I went back and watched the basic communicating between blueprint videos as well, but I couldn’t get custom events or event dispatchers to work.

I think my problem center’s around the idea of getting a useable reference of my widget into the Level Blueprint. I tried building off the Create Widget node with no success either. I guess I’m confused how to make communication connections, since I can’t drop the Widget Blueprint into the level and then reference the instance inside my Level Blueprint like you can with other Blueprint actors. I also tried triggering playback of a matinee sequence from inside the widget’s OnClickedButton function, but with method I can’t figure out how to get my matinee actor inside function either. I can’t pass a reference in with a public variable since I can’t drop the widget into the level and gain access to that variable.

So please enlighten me if you don’t mind! Thanks!

You can make an ActorBP and have it on the begin play create the widget and store a reference to that widget and add it to your viewport if that is your goal. ActorBP can be dragged into the scene.

You can then from any other blueprint including a UMG Widget you can get all actors of that type, get the item at index 0 (assuming you only have 1 ActorBP item in the scene), cast it to the ActorBP, and then you have access to your reference variable (which is the UserWidget for your UMG Widget)

If you go back a few to my bugged project you can download my project which has an example of that you can refer to.

EDIT: Like you I couldn’t get the Level BP to actually communicate outside so I don’t think you are supposed to use it for storing references like you want.
