Commander

by constellation

Commander is a Fabric library that lets server owners and data pack authors define custom commands with arithmetic, explosions and other extension commands.

FabricServer-side onlyMIT LicenseOpen source1.20.1 – 1.21.1

What it does

Commander provides a command extension system built on the vanilla data pack format, so new commands are added by data files rather than by writing Java code. It is server-side only, meaning players join without installing it, and the server alone needs the mod along with Fabric API, which is required. Dark Matter is bundled inside the mod, so nothing extra needs to be installed for it. Files target 1.20.1 – 1.21.1 for Fabric, with 0.9.0-1.21-build.24 for 1.21.1 as the latest beta file, published on 2024-08-06.

Key features

  1. Data pack command extensions

    New commands are defined through the vanilla data pack system, without Java code.

  2. Arithmetic command

    A cmd:arithmetica command evaluates expressions and supports advanced expressions with data access.

  3. Explosion command

    A cmd:explode command creates an explosion at a chosen radius.
