whenever its on it will place slabs on top of spawnable blocks within whatever radius you can. it would be very useful on many server for big farms requiring a lot of spawn proofing. If left on it should continue to place slabs everywhere as you move.
this might be better suited for something like baritone because of the sheer amount of programming that would go into it for pathfinding, determining what blocks can be spawned on, figuring out what blocks can be used to spawnproof, etc
not really, all it would require is like a modified version of crystal aura, where it would just place slabs on the surface of every block in block range.
It would be cool to have a way to automatically walk while placing them though, something like excavate.
yeah thats what I was suggesting
