About the Mob Catcher mod

This mod adds a Mob Capturing Device and a Mob Capturing Device Launcher.

The capturing device can be right clicked on most entities to capture them inside, right click again to release them.

The capturing device launcher can be used to capture or release mobs from afar. It has a capturing, and a releasing mode, indicated by the tooltip.

And before you ask, yes it does work on endermen.

While in capturing mode, the launcher will attempt to fire any unused capturing devices that you have. When an entity is struck, it is removed from the world and placed inside if it is valid for capturing. If no entity is found then it drops as an item.

In release mode, the launcher will fire any filled devices from inside the inventory into the world. Whether it hits an entity or a block, it will spawn the mob with all of it's saved data.

How to install Mob Catcher

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 1.16.5–1.21.1 on Fabric, Forge or NeoForge automatically.

  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 1.21.1. 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 mobcatcher-neoforge-1.21.1-1.jar (43 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.

  4. Launch the loader profile

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

Minecraft 1.21.1 runs on Java 21: with a different Java version the game may close right after launch.
