We have posts and we have ramparts. These aren’t fences, these are balconies/terraces. They can only be placed on a structural floor/roof.
Nelson should add the ability to craft fences. 2x Planks + 2x Sticks = 1 wooden fence. Like the fences you see by the barns. Each fence is half the length of a structure (from side to side. Not from corner to corner)
These fences can be jumped over pretty easily and can be placed on the ground. When trying to install 2 fences, they would snap to eachother. Right click and drag will allow the fence turn around the axis of rotation which is the part where the 2 fences connect.
Nothing too major. It can be small fences, and it can be picked fences. Both can be jumped over. But picked fences require max parkour skill
