Punching another NPC

So, trying to mess around with combat and having no luck I figured I would ask here.

I have a player character with two sphere colliders, one on each hand. I’m turning the collision of these sphere colliders on and off when my character punches. All that is working fine, I can run up to objects with physics enabled and punch them, they go flying off, working as I want.

How do I get those same sphere’s to trigger an event on a NPC? So I can run up to an NPC, punch it and script a reaction to it being punched. I’ve tried things like overlaps, on hits, etc. Not having any luck here.

Meh, just went with a box trace. If anyone does know how to get those sphere colliders to do this please do tell.

I suppose you should configure the NPC collision response channel to block PhysicBodies
