Dynamic Registries Modifier

by SAGUMEDREAM

Dynamic Registries Modifier is a Fabric library that lets other mods inject entries into Minecraft's dynamic registries at runtime.

FabricClient or server, optionalCC0 1.0 UniversalOpen source1.21.1 – 1.21.8

What it does

The library provides a dynamic registry injection tool that other mods can call to add entries to registries that Minecraft loads from data packs, such as biomes, dimensions and worldgen content. Developers use it from code, so no separate setup is needed for players. Files are released under CC0 1.0 Universal, which places the work in the public domain, and the source code and issue tracker are public.

Key features

  1. Runtime registry injection

    Adds entries to dynamic registries while the game runs, without writing a data pack for each change.

  2. Code-based API

    Other mods call the injection tool from their own code, so it is aimed at mod developers rather than players.

  3. Public source

    The source code and issue tracker are public, and the license places the work in the public domain.
