So, this is what I did, and I set up the SurfaceType1 to Sticky but I still don’t know what to do with it (sorry, I startet with UE4 3 months ago). There’s nothing at the StickyWall bluprint. What I was trying to do was, in the wall blueprint, when an actor overlaps it, it sets the boolean Stick to true, and the rest is in the picture. I also tried using the cast to node, but with no succes.
