Concurrent Programming / Programação Concorrente

🏆 Grade: 19/20

A third-year academic project focused on building a real-time, multiplayer game with a high-performance server architecture.
The main challenge was designing a client-server system capable of handling massive concurrent requests using multithreading, while preventing race conditions and deadlocks.

🎮 Gameplay

• Players control a planet orbiting a central sun, navigating with W, A, S, D.
• Collisions:
  • With obstacles → the player dies.
  • With other players → a realistic bounce effect occurs, altering momentum and trajectory.
• Additional features:
  • Display available rooms
  • Create / join rooms
  • Account creation & login system
  • XP / Level system
  • Global leaderboard of all players

🛠️ Tech Stack

• Frontend: Java with Processing for graphics, physics, and input handling.
• Backend: Erlang, leveraging its concurrency model to manage:
  • Real-time player state
  • Collision resolution
  • Scalable, robust server performance
