OwO Lib Mod (1.18.2, 1.17.1) – Open Worthwile Operations Library

11 seconds ago ❘ 0

OwO Lib Mod (1.18.2, 1.17.1) is a general utility library for content-focused modding on Fabric. Particles, automatic registration, tabbed item groups and more.


  • A fully automatic registry system that is designed to be as generic as possible. It is simple and non-verbose to use for basic Minecraft registries but can just as well be used for any kind of custom system that you want to store values in class fields for.
  • A custom implemetation of Item Groups which allows for sub-tabs inside your mod’s group, removing the need to have 3 seperate groups for mods with many items.
  • The RegistryHelper, a simple and logical way to execute code (eg. registration) if and when one or multiple entries you specify are present in a registry. This makes inter-mod compatibility very quick to implement.
  • A wrapper for vanilla’s terrible particle system which makes spawning multiple particles with specified random distributions or precise geometric particles a breeze. This also includes a hassle-free system to trigger arbitrary particle events from the server without much packet setup.
  • Common comparison and verification operations for ItemStacks to make handling them less painful.
