I'll create a 3D multiplayer shooter game using React Three Fiber with Firebase for real-time multiplayer functionality. Let's build this step by step.

I've created a 3D multiplayer first-person shooter game using React Three Fiber and Firebase Realtime Database. The game includes:

1. Multiplayer functionality:

   • Real-time player position synchronization
   • Player health and score tracking
   • Shooting mechanics with hit detection
   • Scoreboard to see other players

2. Game features:

   • 3D environment with obstacles
   • First-person controls (WASD to move, mouse to look)
   • Shooting mechanics (click to shoot)
   • Health system and respawning
   • Score tracking

3. Firebase integration 1:

   • Anonymous authentication for players
   • Real-time database for player positions and game state
   • Automatic player cleanup on disconnect

To play the game:

1. Enter your name on the login screen
2. Use WASD to move around
3. Use your mouse to look around
4. Click to shoot other players
5. Press the players icon in the top-left to see the scoreboard

The game uses your Firebase configuration for the backend, so multiple players can join and play together in real-time.
