Here’s each step I described:
First right click in the content browser and create a class
Do a search for player state and select that as the parent class
Inside of any blueprint you can always see it’s parent class in the upper right corner
Add some variables to your player state, name, stats, score, etc. Make sure to click the eyeball so they’re remotely accessible from other blueprints.
Now inside your widget blueprint you can create a node to cast to the class you created.
But you still aren’t done because you haven’t told the game mode to use your player state. Go back and do the first two steps again, but this time create a Game Mode class called Master_GameMode.
