LDLib2

A modern Minecraft modding library for UI, rendering, synchronization, persistence, and in-game editors.

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 overview
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 editor
Node Graph Toolkit
Create in-game graph editors with nodes, ports, wires, variables, subgraphs, blackboards, undoable commands, and resource-backed graph assets.
LDLib2 in-game UI editor
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.
Generated Configurable property editor
Configurable
Turn annotated Java objects into inspector-ready property panels, including ranges, selectors, lists, resource locations, search fields, undo history, and persistence.
LDLib2 XEI integration
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.

## v26.2.2.43.a * Fixed a cached scene drawing nothing once its blocks changed after its first compile, such as an editor scene filled after it was first shown * Fixed a scene compile cancelled while still running writing into, or freeing, the buffers the next compile builds into * Fixed UI test worlds not freezing time, weather, mob spawning and fire, their game rules being set by names 26.2 no longer has * Improved UI test frame waits to allow time for each frame rather than a fixed timeout, so several test clients on one GPU no longer time out

Что нового
## v2.2.44 * Added `UIElement#reorderChildren`, which puts an element's children in a new order without detaching them, so focus and running animations survive it * Added `UIElement#getContentHost`, the element that children added from outside belong in, which for a `ScrollerView` is its inner container * Added `ModularUI#addFrameCallback` and `removeFrameCallback`, for work that has to run every frame before styles and layout are computed * Improved `UIElement#getOrCreateMessageRPC` so subclasses can call it, and register the named-message RPC from their constructor on both sides * Fixed an element whose id changed after it was added to a UI no longer being found by that id * Fixed labels and progress bars keeping their tick listener after their data source was unbound * Fixed `runParTest` and `runMpTest` building the same files from several child builds at once, failing in projects with NeoGradle subprojects, and reporting an earlier run's result when a run died before writing its own * Fixed UI templates printing a blank line to the console

## v26.3.2.43 * Added `@ManagedCodec`, which saves and syncs a managed field with a codec of your own instead of the accessor registered for its type, from methods a subclass can override * Added `SceneLighting` and `Scene#setLighting`, for choosing how a scene lights its entities and block entities * Added highlighting where files dragged in from outside the game would be dropped * Added popping an editor window out into its own OS window * Added global search and using a folder as a resource provider in the asset browser, and search and sort in resource grids * Added project types deciding how their files open and adding their own entries to the asset browser's menu * Added dropping another view's drag payload on an asset browser folder, for an editor to write it there as a file * Added undo and redo for adding, removing, pasting and moving elements in the UI editor * Added debugging a running UI editor simulation with the UI debugger, by F12 inside it or from the target picker * Added Ctrl+A to select all in the graph view * Added window dialogs remembering the size they are resized to, and fitting themselves to the screen * Added translating an enum's selector entries by `<enum class>.<CONSTANT>` keys * Added configurators remembering the field they edit, taking menu entries from the groups around them, and drawing a value as overridden * Improved the file dialog with a path to jump to and the system folder picker (thanks @spawner1145) * Improved shortcut commands to bubble from the focused element up to the view that handles them, so copy, paste and undo still reach a view whose child has the focus (thanks @spawner1145) * Improved the gizmo so a right-click cancels a drag, and the trackball no longer turns as soon as it is pressed * Improved the asset browser to stop rebuilding for other folders' providers or twice per change, and to find a resource's entry without reading every one listed before it * Improved UI test runs to play in a game directory of their own, emptied first, so a developer's run/ neither affects them nor collects what they leave behind * Fixed block entities and entities behind glass or water in a scene not showing * Fixed name tags, flames, thrown items and the like in a scene not turning to the scene's camera * Fixed a scene lighting its entities and block entities by whatever was drawn before it; they are now lit as in the world by default * Fixed a cached scene's blocks vanishing for good once it was recompiled, and each recompile leaking the GPU buffers it replaced * Fixed a graph or UI editor opened from the resource panel landing behind the Scene tab, and opening a resource that is already open giving it a second editor instead of bringing its tab forward * Fixed UI editor undo not bringing back a removed tab's content, and not reverting a property change when another kind of edit was made in between * Fixed the asset browser's search running on after it was closed, and a file in a folder no provider covers being read twice, with graphs there failing to save * Fixed a shortcut key being kept from the game whenever a view merely listened for its command, rather than only when one acted on it * Fixed the file dialog failing to jump to a path it shows itself, and navigating outside its root folder * Fixed a submenu flipped over its parent menu drawing under that menu's entries * Fixed tree lists leaving a removed child's row behind when folded, unselecting rows that stay through a re-diff, and not following a flattened root's top rows * Fixed a tree list row's arrow selecting its row when clicked and turning it a third time when double-clicked * Fixed unbinding a data source or an observer leaving its tick listener behind (thanks @Darkona) * Fixed an empty fluid slot showing no tooltip (thanks @Darkona) * Fixed scene gizmos and overlays being covered by particles * Fixed a crash when loading an ingredient slot from XML (thanks @vladisfaer) * Fixed a disabled panel, such as a read-only inspector, still letting its fields, pickers, dialogs, paste and reordering change values, while foldouts, scrolling and selection keep working * Fixed renaming a resource to a name its provider cannot store deleting the resource, and a removed file resource being read back when one was made again under its path * Fixed the asset browser losing track of a folder spelled differently from its root, of providers added or removed elsewhere, and of the path of a resource dragged out of a folder with no provider * Fixed graph and UI editor tabs showing the file's type suffix and not following a rename made elsewhere or undone * Fixed a node defined inside another node's definition taking the outer node's later ports and options * Fixed an option that changes a node's ports or options leaving the inspector with the old ones * Fixed a graph's own variable declaration type being discarded when its variables were read back * Fixed menus staying 120 wide, with longer entries cut off or spilling out * Fixed lines drawn into a scene smaller than the window coming out thinner than their width * Fixed pasting into a text field taking only text copied inside the game, not from other applications
