Controllable is a Minecraft Java Edition mod that adds native game controller support, enabling gameplay with Xbox, PlayStation, or other controllers. It features analog movement, context-sensitive button bindings, a radial menu for quick actions, a virtual cursor for menu navigation, and extensive configuration options. The mod supports both Fabric and NeoForge loaders through a clean platform abstraction layer, with shared core logic in the 'common' module and loader-specific implementations in 'fabric/' and 'neoforge/'. It integrates with popular mods like JEI, REI, and EMI via Mixins to ensure compatibility. The architecture emphasizes separation of concerns, with distinct systems for input handling, GUI, and configuration, demonstrating strong modular design and maintainability.
