Introduction
SIRIUS UI (formerly Alan's Unified UI) is a visual renewal project dedicated to reimagining the Minecraft user experience. This initiative establishes a cohesive design language that harmonizes modern minimalist aesthetics with refined visual elements.
With the migration of its core architecture, the project has evolved from a simple visual overhaul into a customization framework powered by the Json UI Engine. Interface layouts and logic are no longer hard-coded but are instead defined freely by users through JSON files.
Technical Shifts & Core Features
🎉 Core Achievement: Json UI Engine
We have introduced the Json UI Engine, enabling a complete separation between interface presentation and functional code. Resource pack creators can now take full control of layouts, textures, and components by writing simple JSON files without modifying Java source code.
🎨 Dynamic & Responsive Layouts
The engine features a flexible coordinate expression system with shortcuts like center and bottom-20, ensuring that your custom UI remains perfectly aligned across all screen aspect ratios.
🚧 Under Active Development
Currently, the Json UI Engine fully supports the restructuring of the "Title Screen" and "Game Selection Screen".
Please note: The Options Menu is still driven by the vanilla system and cannot be modified via the engine at this time. We are working to extend engine capabilities to more native screens.
Important Notes
📢 Version Status: Public Alpha
Please note: This early alpha release focuses on showcasing the customization potential of the Json UI Engine.
Our goal is to provide intuitive tools that empower every creator to easily reshape the game's visuals.
