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

Compatibility Warning

This release represents a build of the largely untested braid-ui-1.21 branch, hence it is marked as an alpha. It is not entirely equivalent in features to 0.13.0 for 1.21.11+ and the features which were backported have not been comprehensively tested for backwards compatibility with mods compiled against previous 1.21 versions of owo-lib.

API Renamings

In preparation for future unobfuscated versions of the game, owo-lib is now developed using the official Mojang Mappings and relevant API elements have been renamed accordingly. Besides a number of straight-forward adaptations (like World -> Level), this also meant that the core class of owo-ui (previously Component) had to be renamed to UIComponent to avoid a name col
