How do I set a Bool in one BP and use it in another?

Hello, I have want to check the overlap of my pawn and a volume in a BP, and to export that information as a bool into my Hud bp. But I can’t figure out how. If you can help me please write a detailed answer.

Set the variable in your player- character / pawn.

Then in your HUD use “Get Player Character” → "Cast To " → "Get ".
