Client Functions

by Velizar

Client Functions lets players run their own functions from in-game, without writing a data pack.

FabricClient and serverMIT LicenseOpen source1.18 – 26.2

What it does

Custom functions can be executed directly in the game, with no data pack needed, which makes it possible to test commands and small scripts from an external tool. The mod is published for Fabric only, for 19 release versions across 1.18 – 26.2. Both client and server need it, and Fabric API and Cloth Config API are required dependencies, with Mod Menu optional for a configuration screen.

Key features

  1. Functions without data packs

    Custom functions run in the game itself, so no data pack has to be built and loaded first.

  2. Configuration options

    Settings can be changed through Mod Menu, or by editing the clientfunctions.json5 file in the config folder.

  3. Dedicated server support

    The mod can be installed on dedicated servers, where it is required on the server side as well.

What the author says

This mod requires Fabric API and Cloth Config API. Additionally, you can install Mod Menu if you want more configuration. Alternatively, you can just modify the config file clientfunctions.json5 inside.minecraft/config. In order for this to work on dedicated servers the mod is required to be on it too.
