How would I send an event from HUD to actor with BP?

I need to send an event pulse from the HUD blueprints to an Actor blueprints. I tried an event dispatch and a custom event and cant figure out how to make it work.

You need to get instance of your actor you want to operate in, what actor you what to get? you store it variable somewhere?

You are going to want to create a custom event on the Actor BP, then get the Actor in your HUD BP and call the event on the Actor BP from the HUD BP.
