About this project

What does BCLib: Remastered add?

BCLib Remastered

The powerful backbone of your favorite dimension mods.

BCLib Remastered is a massive core library and utility mod designed specifically for the Fabric ecosystem in Minecraft 1.21.1. Originally created to power BetterEnd and BetterNether, it provides an enormous toolkit of math libraries, procedural model generation, and API frameworks that streamline large-scale mod development.

While primarily a dependency for our remastered dimension mods, it stands alone as a deeply complex toolkit that handles the heavy lifting of advanced world generation, custom rendering, and mod integration.

🌟 Key Features

  • Massive Developer API: Includes dedicated sub-APIs for World Data, Bonemeal spreading, Tags, and Mod Integration. It takes the pain out of developing complex, data-driven modifications.
  • Advanced Rendering: Supports procedural block and item models right from code, rendering interfaces, and even emissive textures (via _e suffixes) for glowing blocks that bring dimensions to life.
  • Complex Math & Noise Libraries: Packs powerful tools missing from vanilla Minecraft, including Spline helpers, Open Simplex Noise, Voronoi noise, and Signed Distance Functions (SDF) for generating complex geological features.
  • Pre-Defined Complex Materials: Need to generate a full wood set (planks, stairs, doors, signs) or a new stone type? BCLib’s material generators create all necessary blocks, items, recipes, and models automatically.
  • Hierarchical Config System: A robust, JSON-based configuration management system that is highly customizable and saves only the changes you make.

Why "Remastered"? (Exclusive to this Version)

This project is a deeply optimized, modernized continuation of the original BCLib mod, specifically tailored and hardened for Fabric 1.21.1.

We didn't just port the library; we fixed its core to ensure the smoothest, most stable experience possible for modern modpacks:

  • Performance & Core Fixes: Overhauled the underlying helper methods with a focus on thread-safety and concurrency.
  • Sodium & Optimization Compatibility: Addressed critical rendering boundaries. While some advanced features (like direct emissives) naturally conflict with rendering engines, we've ensured that BCLib plays as nicely as possible with modern optimization mods like Sodium without crashing!
  • Polished Integrations & Cleanup: We've hunted down missing models, scrubbed the recipe manager, and squashed console warnings for a seamlessly clean startup log.
