LDLib2
A modern Minecraft modding library for UI, rendering, synchronization, persistence, and in-game editors.
Documentation | Java Integration | UI Guide | Discord | CurseForge | Modrinth
LDLib2 is a complete rewrite of the original LDLib, redesigned around modern Minecraft and NeoForge development. It gives mod authors a higher-level foundation for building UI, in-game tools, renderer-backed content, synchronized data, and persistent runtime systems without rebuilding the same infrastructure in every project.
Feature Highlights
LDLib2 UI Build Minecraft screens with Taffy-powered layout, LSS stylesheets, reusable components, XML definitions, data bindings, RPC events, and HUD overlays. | Data Synchronization and Persistence Annotate fields with @Persisted, @DescSynced, and RPC helpers to generate NBT IO, codecs, dirty-field sync, and packet flow with minimal boilerplate. |
![]() Node Graph Toolkit Create in-game graph editors with nodes, ports, wires, variables, subgraphs, blackboards, undoable commands, and resource-backed graph assets. | ![]() In-game Editor Framework Build Unity-, Blender-, or Blockbench-style tools with dockable views, project files, resource browsers, inspectors, history, settings, and custom editor panels. |
![]() Configurable Turn annotated Java objects into inspector-ready property panels, including ranges, selectors, lists, resource locations, search fields, undo history, and persistence. | ![]() Rendering and Integrations Use LDLib2's shader, texture, model rendering, scene, and editor utilities together with common modding workflows such as JEI, REI, EMI, KubeJS, and Java plugin entry points. |
