NegiLib
NegiLib is a library for Minecraft Paper plugins that provides a common UI system for Java and Bedrock Edition players.
It provides infrastructure for plugins to display and handle multiple types of user interfaces, including:
- Inventory-based GUIs
- Native Paper Dialogs
- Bedrock Edition forms through Geyser
- Player input and UI action handling
- Cross-platform UI rendering
NegiLib is primarily intended to be used as a dependency by other plugins. It does not add significant gameplay features by itself.
Installation
Server owners normally only need to install NegiLib when another plugin lists it as a dependency.
Place the NegiLib JAR in the server's plugins directory and restart the server.
If no installed plugin requires NegiLib, there is generally no reason to install it by itself.
For developers
NegiLib provides APIs that plugins can use to build and display interfaces across supported Minecraft clients.
Public developer documentation and examples are not yet available and are planned for a future release.
