Im sure this has popped up in the minds of more than a few players… perhaps even in a post or two.
What I had in mind was fencing. Now I know we can sort of make a rough(and ridiculously costly) fence by using a foundation, two pillars, and a wall all set in the middle snap points. Adding up all the wood that is needed for that would be … 200 wood… for one build square. A bit much for a privacy fence, hrm?
Now, what I was thinking would be a semi low cost ‘fence’ that players could see through, and shoot through, that would simply block the movement of players and animals. To move past it you would either need to build next to it and jump it… or use the gate(think a door). Unlike wooden/metal walls, this fence could be destroyed/damaged by melee, guns, and explosives.
