by fatigue_dev

Fatigue's GUI lib is a Fabric library of reusable screen building blocks for mod developers who build custom interfaces.

FabricClient or server, optionalAll rights reserved1.21.11

What it does

The library supplies simple screen parts such as labels, panels, buttons and toggles, plus themes and base layout helpers, so a custom GUI can be assembled from ready pieces. It is a library mod in the GUI category, and an optional example content set shows how another mod can depend on it to open custom styled screens. Only the Fabric loader is supported, with a single game version, 1.21.11.

Key features

  1. Reusable widgets

    Labels, panels, buttons and toggles can be placed on a screen as building blocks.

  2. Theme support

    Themes let a set of screens share one visual style without rewriting each widget.

  3. Base layout helpers

    Helper classes arrange the parts of a screen, reducing the code needed for each new interface.
