Hi, I just started to use Interface and I think I get along, at least I got some to work already.
But this one does not work and I cant figure out why.

Here the process:

  1. I get a reference by box collision, i get the correct reference printed so that works.

  2. I call this function, since there are a few branches before I made sure it gets executed by this print, works.

  3. the function within the referenced object is not firing.

Thanks for your help!

I notice you’re checking implementation on a different kind of interface from the one you made the call on. Probably look at that…

just solved it. My SpawnPreviewItem has no collision and its spawns the same actor but activates its collision. I had a wrong connection there and actually activated the collision for the preview, so the reference was indeed set but for a wrong item.
Cheeky little connection
