wasabii0726 How can I make it so that when I walk, a road spawns right under me, endlessly, without having to put up blocks myself?
Answer:
If you want to be walking manually, you can use ScaffoldWalk, which is built for this exact purpose. It will place one block under your feet whenever there isn't one already.

If instead you want Wurst to do the walking for you, and optionally make a bigger road with lights, then you can do that using Tunneller. It will automatically fill the floor of your "tunnel" with blocks, even when there is nothing to actually tunnel through. It also has the option to place torches so that the entire road will be spawn-proof.

Hope this helps!
