How do I install Commander?

Install the matching mod loader (Forge, Fabric or NeoForge) for your Minecraft version. Download the .jar. Put it in the .minecraft/mods folder and launch that loader profile. Opens on Modrinth — not every file is mirrored on our own servers.

What Minecraft version does Commander work with?

The listing gives Minecraft 1.21, 1.21.1. This is the version stated by the author or source site, not something we verified ourselves.

Which Minecraft do you have?

Every version of the game needs its own build. Pick yours, then download — the wrong build installs fine and then does nothing in the game. This mod is built for Fabric only.

Minecraft 1.21–1.21.1Newest
Minecraft 1.20.4
Minecraft 1.20.1

⬇ Download for 1.21–1.21.1 ⬇ Download for 1.20.4 ⬇ Download for 1.20.1

I don't know my version or loader

Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.

No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.

Quick Introduction

Commander is an extension of the vanilla data pack system.

It adds a new event system:

{
  "event": "commander:after_killed_by_other",
  "commands": [

  ]
}

Flexible JSON commands:

{
  "type": "commander:commands",
  "selector": "commander:random_player",
  "commands": [
    "/cmd:explode ~ ~1 ~ 2"
  ]
}

New / commands:

cmd:arithmetica: /cmd:arithmetica "round(346.45, 1)"
cmd:explode: /cmd:explode ~ ~ ~ 4

Support for advanced expressions with data access:

minecraft:this_entity.isInWaterOrRain

/say ${{ origin.x }}

There are no client-side features available, everything is done on the server.

Commander is still in beta, so things can change, develop, break.

Modpack creators, DO NOT INCLUDE the .commander folder!
