Draw Text To HUD When Looking @ Specific Object

*Hey everyone, I’m trying to update my HUD with a string of text when specific objects are traced. Right now I have it set-up so I get a print string when “Installations” are line traced. Below is a picture of my line trace set-up and I thought I could just create an event dispatch that I could call in my HUD blueprint to update it every time one of these objects is traced. Problem is I can’t figure out how to call the event from My Character in My HUD.
Additional question is how could I trace specific text depending on which “Installation” was called. I’d like to have about 20 different objects in the Installation class but unique text drawn to the HUD for each one.
Any help at all is appreciated, thanks a lot!

Well I ended up using the UMG tutorial on youtube for inspiration on how to display text when I’m I trigger a specific object’s BP, so I’m not using raytracing to do this anymore.
