Lattice

Unified UI framework for Minecraft clients on Fabric (Minecraft 26.1.2). Lattice supersedes Knit (client base library) and Vexel (NanoVG UI library), merging both into one dependency with a single event bus, one input abstraction, and one screen stack.

Features

• NanoVG vector renderer (rects, gradients, text, images, SVG, shadows)
• Constraint-based layout with scrollable containers and a full widget set
• Semantic theming (Theme) — retheme every widget in one place
• Time-based animations with easing and presets
• Single event bus with client lifecycle, tick, and render events
• UIScreen bridging vanilla screens, plus direct-draw HUD hooks
• Commodore command DSL over Brigadier, fluent Component text builder
• Tick and wall-clock schedulers, client/input utilities

Documentation

Full docs live in docs/ — start with getting started, or the Knit/Vexel migration guide. Design rationale is in docs/architecture.md.

A runnable demo mod lives in example/: /lattice opens a screen showing every widget; /lattice hud, /lattice chat, and /lattice greet demo the render, text, and command APIs.

Building

With Nix: nix-shell --run './gradlew build' (requires JDK 25 otherwise). Publish to your local Maven repository with ./gradlew publish (artifact xyz.meowing:lattice-26.1.2-fabric).

Runtime NanoVG natives ship for linux, linux-arm64, windows, macos, and macos-arm64.
