General Notes

  • This mod identifies as a Client Side-only mod
    • This means it will not run on the Server's side.
    • Fabric and Quilt mod loaders will simply ignore the
      mod, while other mod loaders may crash.
  • Some versions of the mod for Minecraft 1.14.x and above require
    the Fabric API
    and the Fabric mod loader
  • Some versions of the mod for Minecraft 1.13.x require
    the Rift API
    and the Rift mod loader
  • Some versions of the mod for Minecraft 1.1.0 and below
    require Risugami's ModLoader

Features

This library mod offers various API utilities that have been developed over the years,
initially part of CraftPresence,
that have been designed to work on over 50 versions of Minecraft, from the earliest Alphas to the latest Releases.

These APIs range from utilities that can help with Rendering/UI design, Update Checker and Translation ease-of-access,
as well as the APIs provided through the sibling-project, UniCore

Disclaimers & Additional Info

Minecraft Issues + Additional Build Info

Despite best efforts, issues can occur due to the state of the Minecraft Codebase.

These issues can hinder certain portions of the backend in addition to cause certain parts of the mod to not work.

With this in mind, please note the following:

  • Minecraft 1.16 and above
    • As more parts of the game become data-driven, some modded data is no longer able to be automatically retrieved
      without first being in the world.
  • Minecraft 1.15 and below
    • MC-112292: When interacting with the RenderUtils#drawItemStack method, used in the v2 Item Renderer, blocks
      using certain renderers may fail to display properly.
    • Additionally, on 1.15.x exclusively, z-level issues may occur on Screens using this method
  • Miscellaneous Issues
    • Due to obfuscation issues in earlier versions of Minecraft, incorrect data may appear when using certain parts of
      the mod.

Additionally, some settings or API calls may perform differently under certain MC versions.

Frequently Asked Questions

Does UniLib need to be installed on the Minecraft server?

No. Modrinth marks UniLib as unsupported on the server side. Install it only in your local Minecraft mods folder. Your server can remain unchanged unless the mod page lists an additional dependency.

Which version and loader does UniLib require?

Use a file for fabric, forge, modloader, neoforge, quilt, rift and your exact Minecraft version. Supported versions include 26.2, 26.1.2, 26.1. Files for different loaders are not interchangeable.

UniLib is not working – what should I check?

First check the Minecraft version, loader version and required dependencies. Put the .jar file in your local .minecraft/mods folder and remove older duplicates. Because this mod is client-side, adding server RAM will not fix it.
