Hi thank you,
So as it turns out I didn’t think I needed to do any referencing to classes/ actors when it came to interfaces. As soon as I did a for each loop to check for all actors with interface, the event then fired correctly as expected.
I thought I could just set my actor up with an interface and pull off from the interface event what I wanted to happen. Then just call the interface from my pawn when I pressed a key. I didn’t know I needed to look for any actors with the interface first.
