@chen1(View Post) Rejected billions of times. If you really need one, use Newt. gravity. Powered invs, also known as E-wall as an element, has been around for a while now. There's been no answer, though there's certainly an use. Colour coded wire could be used, but it's somewhat useless, because one can get a block of wires by repeatedly using PTCT, NTCT, INWR and METL in a block. Wire crossing can be done via walls or INST. ROPE is in fact useless. It can be like this, but it can in no way interact with the world, moving solids and all that.
