About this Mod
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. |

LDLib server crashes on startup – what to do?
Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (26.2). You can switch loaders with one click in the panel.
Is LDLib compatible with fabric and forge and neoforge?
LDLib officially supports fabric, forge, neoforge for Minecraft 26.2, 26.1.2, 26.1.1. Note: Forge and Fabric mods are NOT cross-compatible – pick one loader and stick with it. The Mado dashboard automatically detects incompatible loader combinations.
Server lagging with LDLib – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if LDLib consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
