🛠️ OneKeyMiner (Forge / NeoForge) – Chain Mining & Planting Mod

📋 Overview

OneKeyMiner offers a seamless chain-mining and farming experience on both Forge and NeoForge. Hold down your chosen key (default: ~) to auto-break adjacent identical blocks or plant seeds in bulk. Both versions deliver identical core functionality—mining, planting, tool durability protection—while NeoForge further expands interaction capabilities.

How to install OneKeyMiner

With Millida Launcher

  1. Install Millida Launcher

    The launcher is free: download it at millida.net/launcher and sign in with any nickname.

  2. Click “Install” on this page

    The launcher opens and installs the mod for Minecraft 1.12.2–26.3 on Fabric, Forge or NeoForge automatically, together with its dependencies: Fabric API.

  3. Launch the game

    A profile with it appears in the launcher: click “Play”.

Manually

  1. Install Fabric, Forge or NeoForge

    The loader must match the game version of the mod file, for example Minecraft 26.3. After installing it, a separate profile appears in your launcher.

  2. Download the file for your version

    In the version list above, pick the file onekeyminer-neoforge-1.6.9-26.3.jar (324 KB) for your game version and loader.

  3. Put it in the mods folder

    The folder is inside .minecraft (Windows: %appdata%\.minecraft\mods). If it does not exist, create it. Required dependencies go there too: Fabric API.

  4. Launch the loader profile

    Open “Mods” in the main menu: OneKeyMiner should be in the list.

On a server

  1. A server on Fabric, Forge or NeoForge

    The mod only works on a server with the same loader and game version, for example 26.3.

  2. File goes into the server’s mods folder

    Stop the server, put the mod file into the mods folder and start the server again.

  3. Use the “To server” button

    On Millida Hosting, the button at the top of the page uploads the file to your server and restarts it for you.
