Immersive Machinery [Fabric/Forge]

Overview

Immersive Machinery gives players four autonomous machines that tackle the most repetitive parts of a Minecraft playthrough. The Tunnel Digger handles bulk mining, the Copper Fin opens up underwater exploration, the Redstone Sheep farms crops without supervision, and the Bamboo Bee shuttles items between containers automatically. All four share the same rustic copper-and-iron aesthetic, fitting naturally alongside vanilla builds without clashing with the game's visual style.

Each machine functions as a deployable entity rather than a traditional placed block. Right-clicking the crafted item on the ground or water surface spawns the machine in the world, where it can be mounted, programmed, or left to operate on its own.

Prerequisites

Immersive Machinery requires Immersive Aircraft as a mandatory dependency. All four machines use components from Immersive Aircraft's crafting system: the Engine, Propeller, Boiler, Hull, and Quadrocopter must all be crafted before any Immersive Machinery machine can be assembled. The Boiler requires 7 Copper Ingots and 1 Furnace. The Engine requires 3 Cobblestone, 2 Pistons, 1 Blast Furnace, and 1 Boiler. The Propeller requires 5 Iron Ingots.

This shared component system also means the Tunnel Digger and Copper Fin can accept Engine upgrade items from Immersive Aircraft, improving their speed and efficiency. Landing gear upgrades from Immersive Aircraft do not apply to ground or water machines.

Tunnel Digger

The Tunnel Digger is a large, slow ground vehicle built for bulk mining. Mount it by right-clicking, then drive forward with the standard movement keys to bore a 3x3 tunnel through any terrain, collecting every mined block directly into its 87-slot internal inventory. The machine snaps to 90-degree compass headings automatically when not turning, so tunnels stay straight with minimal effort.

Press Space to angle the drill upward or Shift+Space to angle it downward, controlling the tunnel's vertical direction on the fly. Use the Horn keybind to toggle the drill on or off without dismounting, useful when navigating through pre-existing tunnels. The Tunnel Digger's GUI also provides a drill direction button for mouse-based control.

The Iron Drill is the base version required to assemble the Tunnel Digger. Upgrading to Diamond or Netherite at a Smithing Table increases block destruction speed. Loading the shard slot with Amethyst Shards doubles drilling speed on top of the drill tier bonus, with each shard having a chance to be consumed proportional to the hardness of blocks mined.

Copper Fin

The Copper Fin is a compact submarine powered by a Conduit, which provides unlimited air supply to any passenger aboard. Water vision is substantially improved while riding, with underwater clarity is always at least 75% of surface visibility, regardless of depth or water type. Ocean Monument raids, deep-sea cave exploration, and underwater construction projects all become far more manageable without the constant threat of drowning.

The Copper Fin can only propel itself while fully submerged. Once it surfaces, it loses all drive and floats until it submerges again. Steering is handled by the standard look-and-move controls, with the vehicle tilting to reflect pitch and roll during movement. A hatch-close sound plays when mounting and a hatch-open sound when dismounting, adding to the immersive feel.

Press H (the Horn keybind) or click the Sonar button in the Copper Fin's GUI to activate the sonar. The pulse applies the Glowing effect to every living entity within 48 blocks for 1.5 seconds (30 ticks), revealing mob locations through terrain. The sonar has a 3-second (60-tick) cooldown between uses.

Redstone Sheep

The Redstone Sheep is an autonomous crop harvester that operates without any player involvement after initial placement. It scans the surrounding area up to 5 blocks horizontally from its home position for mature crops, harvests the drops, and resets each plant to age 0 to replant in place. The machine recognizes Wheat, Carrots, Potatoes, Beetroot, Nether Wart, Cocoa Beans, and Pitcher Crops natively, as well as Grass blocks by default configuration.

The Redstone Sheep stores harvested items in its 15-slot inventory. When the inventory fills or the machine runs low on fuel, it navigates back to its home position and waits to be unloaded and refueled. It resumes scanning automatically once recharged. Place it at the center of a crop field for the most even coverage across all four directions.

The configuration file allows adjusting the horizontal scan range beyond the default 5 blocks, the fuel cost per harvest (default 20 ticks), and which crop types are considered valid targets. Custom mod crops can be added or excluded via the `validCrops` map in the config.

Bamboo Bee

The Bamboo Bee is a programmable transport drone built from a modified Quadrocopter. It flies autonomously between designated containers, moving one stack of items at a time from a source chest to a destination chest. Setting it up requires a specific interaction sequence: Sneak+Right-click a container once to mark it as an output (destination), then Sneak+Right-click another container to set it as an input (source). The Bee begins operating immediately once both positions are assigned.

Multiple input and output containers can be registered, allowing the Bamboo Bee to distribute items across an entire storage network. Two distribution modes are available: Round Robin cycles through all output containers equally with each delivery, while Pick first always delivers to the first available output container that has space. The active mode is toggled in the Bamboo Bee's GUI.

An item filter slot controls which items the Bee will transport. By default the filter acts as a whitelist, moving only items that match the filter slot. Switch to blacklist mode in the GUI to block specified items instead. Enabling the Filter by NBT Tag option forces the Bee to treat enchanted and non-enchanted versions of the same item as distinct, preventing mixed stacks. Sneak+Right-click any non-container block to clear all registered positions and reset the Bee completely.
