I'm making a symmetrical map which centers around a hill, and I've added fences off to the side of the hill on both sides of the map to keep players directed toward their side buildings in the map. Basically, what I want to know is if there's a way to make these fences stop players as barriers, but not allow them to walk on top of them. I don't want players to be able to walk straight from the hill to the side buildings' second floors via the top of the fences. A simpler question would be: is there an entity which repells but doesn't clip players? Thanks for the help, I'm a noob and really need an answer to this one.
