About this project
What does LowDragLib2 - Forge (Unofficial Port) add?
This is an unofficial Minecraft 1.20.1 Forge port of LowDragLib2, maintained by weiliangyan.
LDLib2 is a base library for mod developers (not a content mod for players), providing:
- In-game UI framework: components, layout, styles, XML UI, data binding and events
- In-game editor: resource manager, inspector panel, UI template editing, preview and save
- Rendering tools: GUI textures, model/scene rendering, shader wrappers
- Sync & persistence: NBT, Codec, field sync, RPC, network packets
- Resource system: color, texture, UI template and renderer resource loading/editing
- Ecosystem compatibility: JEI, REI, EMI, KubeJS and more
**Requirements**
- Minecraft: 1.20.1
- Forge: 47.4.10 (or any 47.x)
- Java: 17+
- Required dependency: Kotlin for Forge
**Installation**
Put the built -all.jar into the mods folder on both client and server. When used on a multiplayer server, the client and server must run the same version, otherwise network channel mismatch or connection failures may occur.
**In-game editor**
Players with OP permission can run /ldlib2_ui_editor on the server to open the UI editor, used for developing and debugging UI templates (not a player menu). It supports creating/editing XML UI, managing resources, adjusting element properties in the inspector panel, and saving UI templates.
