Tunneler & Machines
by neikn2105
Tunneler & Machines adds automatic, programmable machines that dig long underground tunnels and lay track along them, driven by a simple numeric route language.
What it does
Players build machines that dig tunnels on their own, and each machine is set up with a route written as a short sequence of numbers. A route is made of MOVE instructions for distance and direction, with codes for turning left, right, down, up and continuing forward. The route is written on a custom sign that carries a name, and a machine is configured by right-clicking it before it starts. Long, nearly endless routes are possible as long as enough resources are supplied.
The mod adds a small set of practical machines and tools, including tunnelers at several tiers, a railer that lays track, and a torch marker that places lights as the machine moves. Starter keys, tunneler upgrades and drills extend what the machines can do. Files are published for Forge 1.20.1 and run on the client and server, so the server and every player need the mod. The mod is released under the Creative Commons Attribution 4.0 license and is not open source.
Key features
Programmable routes
A route is a string of numbers that sets distances and directions, so a machine can follow custom paths underground.
Tunneler machines
Iron and diamond tunnelers dig tunnels automatically once supplied with the resources their route requires.
Railer and track
A railer machine lays track along the tunnel it follows, and a railer marker can be placed to mark its progress.
Upgrades and drills
Tunneler upgrades in two tiers, iron drills and diamond drills raise the speed and reach of the machines.

Use cases
Long underground routes
A passage running far from a base can be set as a route, and a machine digs it without manual work.
Automated track building
A railer can follow a tunnel route and lay track behind it, which suits transport lines between mining areas.
Who it’s for: Players who enjoy automation and writing small programs will find the route language suited to tunnel digging. Server owners can run the machines for shared mining projects, since every player on the server needs the mod.

This mode adds few practical machines that help you to dig long underground tunnels. Every mychine is in-game programmable with very simple language that consists only of numbers.
