Thanks for the replies. I wasn’t expecting someone to hand me a step by step tutorial 
I just needed to know if it was possible before I started to invest the time attempting it.
So far I have setup my flashlight blueprint which was easy enough. The enemy AI basically need to ‘seek out’ the player and trigger a death event if it reaches the players collision volume, I can take care of that. All I need help with is having it so if the flashlight (point light) touches the AI collision, it will drain its health and kill it, or retreat.
In blueprints how would I go about doing that? I’ve never seen a light source act as a trigger before?
