Build guide

1. 01Initialize Web-Based 3D Game Client

   Scaffold a web application using Vite, React, and React Three Fiber to render basic 3D environments and avatars.

   Create a new Vite project with React, TypeScript, and Tailwind CSS. Install Three.js and @react-three/fiber along with @react-three/drei. Build a sample 3D scene containing a ground plane, basic lighting, and a controllable third-person capsule avatar that responds to WASD keyboard input for movement. Ensure smooth camera follow logic and clean component separation.

2. 02Implement WebSocket Multiplayer Networking

   Set up a Node.js backend with Socket.io to sync player positions and movements in real time across connected clients.

   Set up a Node.js and Express backend integrated with Socket.io. Write server-side event handlers to track connected users, broadcast player position and rotation updates at 20 ticks per second, and handle player join/leave events. On the React frontend, connect to the WebSocket server, instantiate remote player meshes for other connected clients, and interpolate their positions smoothly to avoid stuttering.

3. 03Build User Accounts and Game Catalog DB

   Configure Supabase to handle user authentication and store metadata for community-created mini-games.

   Integrate Supabase Auth into the React frontend for email/password user registration and login. Create a PostgreSQL database schema using Supabase containing tables for 'profiles' (username, avatar_url) and 'games' (title, description, creator_id, scene_config_json). Build a dashboard UI where users can view a list of available mini-games and click to launch into a multiplayer room.

4. 04Add Basic Level Editor / Creator UI

   Create a rudimentary in-browser editor allowing users to place basic 3D blocks and objects into a scene.

   Build an in-browser level editor overlay for the 3D scene. Allow users to select primitive blocks (cube, sphere, cylinder), click on the grid to spawn them, adjust their position and color, and save the resulting array of block transforms as JSON. Update the game loading logic so that when players enter a game room, the saved blocks are dynamically instantiated into the Three.js scene for all participants.

5. 05Polish UI, Deployment, and Error Handling

   Refine the dashboard interface, handle network dropouts gracefully, and deploy the application to Cloudflare and Supabase.

   Design a clean, modern dashboard UI inspired by gaming launchers using Tailwind CSS. Add toast notifications for connection errors, automatic reconnection logic for WebSocket drops, and loading spinners for asset fetching. Provide step-by-step configuration instructions for deploying the frontend to Cloudflare Pages and connecting it to the Supabase backend.
