How do I make a "look at" object type of event?

Hi, I’m trying to make a “look at” event based on my slighty big crosshair in the middle of my screen. I’ve already figured out how to turn my camera around and properly send out a line trace. The problem is that a line trace is not what I’m looking for. I’m look more to creating this event based on the screen space of my crosshair and translating that to world space. Then using that world space to check if I am looking at an object. Is there a way to do that? I’m not really familiar with Blueprints, so any help would be appreciated.

I think your best bet is still a linetrace using a custom channel from camera. Why don’t you want to use a linetrace?
