Auto-attack onclick?

I am still very new to Unreal Engine, have only been using it for about a month. I really want to make a game that plays somewhat like Diablo or any of those hack and slash 3rd person games where you click on an enemy and your character runs up and attacks it. I have read the Melee attack tutorial, and watched a few other videos but they all seem to have the combat system where you just attack randomly when you click the attack button which is not what I want.

I have a feeling it is going to have something to do with "Event Onclick’ in the enemy’s event graph but I cannot get it to work like I want. I am just hoping someone with more experience might be able to offer me some ideas on how to add a auto-attack on click system.

I do not care at all about animation advice, I already have that figured out and there are more then enough resources out there for that. Just want to have a click attack combat system.

Thank you in advanced.
