What’s inside

Tunnel Bore

Mod version: 0.1.0
Updated: September 2026

What it does

Place the Tunnel Bore on the ground facing where you want the tunnel: its drill points the way you were looking. Use it holding coal or charcoal to fuel it (each piece digs 4 blocks of tunnel, a block of coal 36, and it holds fuel for 256 blocks), and holding torches to load up to 64 of them. Crouch and use it to start or stop it; use it with anything else in hand to see the fuel and torches left. While running it digs a tunnel 3 blocks wide and 3 tall, about one block a second, and moves itself forward after each slice. What it digs drops in the tunnel behind it as if mined with an iron pickaxe: cobblestone from stone, raw iron from iron ore, diamonds from diamond ore. Sand and gravel stacked up to 12 high above the tunnel are dug out too, so nothing falls on it, and it places a torch on the wall every 8 blocks while it has torches.

It stops and says why on the action bar rather than dig into water or lava, even water beside or above the next slice, or into chests and other blocks that hold things, spawners, bedrock, obsidian, other mods' blocks, taller sand or gravel, or a drop with no floor. It works only while a player is within 32 blocks and waits while something stands in its way. Pick up what it digs as you follow it: like any dropped items, they vanish after 5 minutes. Breaking it gives back the bore, its torches, and 1 coal for every 4 blocks of fuel left, rounded down. Named coal and torches stay in your hand. Anyone playing in your world can fuel, start or break it.

How to install Tunnel Bore

Import the .mcaddon, then turn on both packs in your world's settings (Behavior Packs and Resource Packs). No experiments are needed. Needs Minecraft Bedrock 1.26.45 or later.
At a crafting table, put an iron block, a piston and an iron block across the top row; a copper ingot, a diamond pickaxe and a copper ingot across the middle; and an iron block, a furnace and an iron block across the bottom.
Look toward where you want the tunnel and place the Tunnel Bore on the ground. Use it (right-click on Windows, tap on touch screens) while holding coal, charcoal or blocks of coal to fuel it, and while holding torches to load them.
Crouch and use it to start it, and again to stop it. Follow it to collect what it digs, and use it with an empty hand to check its fuel.
