Unreal Trace Channels

Author: Landon Henry

While working on Luddite this week, I started playing around with trace and object channels in Unreal Engine 5. I needed to use them for the target lock system, hitboxes, and fixing a camera bug. In order to do this I had to edit some trace channel settings in the project settings. Nothing was happening though. I'd change the trace channel option, aaaand...nothing. 

I ended up fixing this by going into collision presets for the actors and adjusting their interaction with other trace and object channels. This was needed because the actor collision wasn't interacting properly with the trigger boxes for the things I was working on. This caused all sorts of problems like the target lock not locking onto enemies if they're near a wall, or hitboxes just doing nothing. Thankfully, it was an easy fix. If only everything was that easy though.
