CRLib

by Tarantel

CRLib is a Forge and NeoForge library by Tarantel that Roost Ultimate and other mods use to load new content from data.

ForgeNeoForgeClient and serverAll rights reserved1.20.1 – 1.21.11

What it does

CRLib gives mod authors helpers for building features on top of it. It adds a new bucket-like system for handling fluids and generates fluid eggs for the Roost Mod through a full datapack or resourcepack, so models, JSON files and textures can be supplied without writing new code. Roost Ultimate requires it, and Just Enough Items (JEI), Roost Ultimate and Roughly Enough Items (REI) are optional companions.

The library runs on client and server, so the server and every player need it. Files are published for 1.20.1, 1.21.1 and 1.21.11, with the latest NeoForge build 0.0.9-1.21.11 dated 2026-01-30. The code is under All rights reserved, so it is not open source.

Key features

  1. Bucket-like fluid system

    A new bucket-like system lets fluids be picked up and placed through item handling added by CRLib.

  2. Datapack-driven generation

    Fluid eggs for the Roost Mod are generated from JSON files in a datapack or resourcepack, with no Java changes.

  3. Resource loading for models and textures

    Models, JSON definitions and textures are loaded from resource files, so content can be added without compiling a new mod.
