About this project

What does Citadel (Legacy) add?

Citadel (Legacy)


A legacy backport of Citadel for Minecraft 1.12.2, bringing the powerful animation and entity framework used by many large-scale creature mods to older Forge environments.

This project preserves the core systems and behavior of modern Citadel while adapting them for stable use on Minecraft 1.12.2.


About the Original Project

Citadel was originally developed as a shared backend library for Forge and serves as the foundation for many major creature-focused mods.

You can find the original version here:
👉 Original Citadel (Forge)

All credit for the core framework design and underlying systems belongs to the original developer. This legacy backport exists to provide compatibility and long-term support for the 1.12.2 modding ecosystem.


What Is Citadel?

Citadel is a shared backend library that provides:

  • Advanced entity animation systems
  • Custom model handling
  • Network syncing utilities
  • Data-driven behavior helpers
  • Common creature framework logic
  • Tools used by many large-scale mob and creature mods

A large number of mods depend on Citadel to function properly.


Why This Backport Exists

Many modern mods and ports rely on Citadel, but Minecraft 1.12.2 remains one of the largest and most active legacy modding versions.

This backport:

  • Adapts newer Citadel systems for 1.12.2 Forge
  • Preserves original behavior wherever possible
  • Maintains compatibility with legacy mod environments
  • Helps make large-scale backports possible
  • Provides long-term support for older modpacks and projects

The goal is stability, compatibility, and maintaining the powerful framework capabilities that many creature mods rely on.


Intended Use

This is a library mod.

You do not install this on its own unless another mod requires it.

If a mod says it requires Citadel (Legacy), install this version.


Version Support

Built specifically for:

  • Minecraft 1.12.2
  • Forge-based legacy environments

Always ensure your Forge version matches the required version listed in the files tab before installing.


Notes

  • This is a backport and compatibility project
  • No standalone gameplay content is included beyond what is necessary for the library to function
  • Designed for clean integration and minimal overhead
  • Intended to support ports and legacy creature mods on 1.12.2

If you're a developer porting a Citadel-dependent mod to 1.12.2, this project exists to help make that process possible.


Modpack Use

This mod is free to use in modpacks.

You are welcome to include it in public or private modpacks without permission.
