API

Core functions and utilities for building and displaying UI.

Functions

• render(root, player, screen) — Entry point for all UI. Displays a component tree to a player.
• createContext(defaultValue) — Create a context object for passing values down the component tree without prop drilling.

Advanced

• Custom Native Components — register your own native component type that the runtime serializes and your resource pack's JSON UI decodes. Requires JSON UI and serialization knowledge.

Screen Descriptors

• Screen.Scroll — Default scrolling form layout; scrolls when content overflows and shows no scrollbar when it fits. (Currently the only built-in screen type; the descriptor system is kept for future types.)

Next Steps

• Components - Built-in components that you can use in your JSX
• Hooks - Add state and effects to your components
