It gives you tiles which power assemblers, inserters, etc. which sit on top of them, also special tiles which pass circuit signals to neighbors, also a power tap which lets you feed signals and power to these tiles.
It seems to function as I want it too, though I realize my artwork is a little crude. One annoyance is the automatic wire placement. Vertically, they look ok, but horizontally, they look festooned, which is odd. I'd like to just hide the wires altogether. I looked at some posts about overriding sprites, but I want to leave the wire sprites for the normal electric-pole entities the same.
I'd be grateful for advice about my code - this is my first effort in lua!
Thanks!
