I mentioned this before but no luck with a response but now I have an idea how it could work ...
A Block Zone.......Something like a trigger zone so we could place it in a gap for instance and use the points to stretch it however big we need it... The only problem may be is that the blockage height may have to be infinite but hey it would stop gamers running up that hill we don't want them to or that little gap you can just squeeze through

The only person ever to get all his work done by "Friday" was Robinson Crusoe..
