About this Mod

Header
A general utility, GUI and config library for modding on Fabric and Quilt  


Features include:

  • owo-ui, a fully-featured declarative UI library for building dynamic, beautiful screens with blazingly fast development times

  • owo-config, a built-in, customizable configuration system built on top of owo-ui. It provides many of the same features as Cloth Config while many new conveniences, like server-client config synchronization, added on top

  • A fully automatic registration system that is designed to be as generic as possible. It is simple and non-verbose to use for basic registries, yet the underlying API tree is flexible and can also be used for many custom registration solutions

  • Item Group extensions which allow for sub-tabs inside your mod's group as well as a host of other features like custom buttons, textures and item variant handling

  • A fully-featured networking layer with fully automatic serialization, handshaking to ensure client compatibility and a built-in solution for triggering parametrized particle events in a side-agnostic manner

  • Client-sided particle helpers that allow for easily composing multi-particle effects

  • Rich text translations, allowing you to use Minecraft's text component format in your language files to provide styled text without any code


owo is documented in two main ways:

  • There is rich, detailed JavaDoc throughout the entire codebase
  • There is a wiki with in-depth explanations and tutorials for most of owo's features over at https://docs.wispforest.io/owo/features
