HaoHan Display UI

HaoHan Display UI is a Paper and Purpur plugin for creating interactive interfaces directly inside the Minecraft world.

It gives plugin developers a simple API for combining text, items, blocks, panels, and clickable buttons with Display Entities. The engine handles rendering and interaction, while the plugin using it decides what the interface should do.

It can be used to build machine panels, guide boards, item lists, paginated menus, command buttons, documentation links, and private interfaces for individual players.

This is an engine for other plugins, not a ready-made gameplay menu. Install it when another plugin requires it, or use the included demo to see what it can do.
