Fighting game - How to always make fighters face each other?

For sure, well I was using UE4 when I made this. Are you using 4 or 5? It is doing anything? Describe your situation.

I am actually behind when comes to the fighting game template. I have spent most of my time in the Beat Em Up template.

Where I talk about using box collisions for this, I thought I figured out a way to do it without box collisions. Just by checking which player is facing and adjusting rotation accordingly.
