Have not been able to get to this for a bit but here it is. So far, this is what I was able to actually get working. And it all works how I want it to (minus the shooting issue) but if P1 stands on the roof and P2 enters the building, P1 falls through the roof 
Tried getting a cast to BP on to it to make sure it only happens to the one player but I couldn’t figure that out.
