Serpent Clash

Serpent Clash is a fast-paced, real-time multiplayer snake game where players compete to outmaneuver and outgrow their opponents. Players control serpentine avatars, navigating a dynamic battlefield while dodging opponents. The game leverages modern WebSocket communication for smooth, real-time player interaction and incorporates client-side prediction to ensure responsive gameplay even in high-latency situations.

The game is built with a combination of Vue.js for the client-side and Go for the backend, following an authoritative server model to ensure fairness and consistency in gameplay. With real-time movement tracking and competitive elements, Serpent Clash challenges players' reflexes and strategic thinking as they slither to the top of the leaderboard.

Key Features:

  • Real-time multiplayer with WebSocket communication
  • Smooth player movement with client-side prediction and server-side validation
  • Dynamic snake rendering based on multiple coordinates and mouse input
  • Comprehensive player stats displayed on the client-side
  • Authoritative server design ensuring fair and consistent game state across all clients
  • Server Reconciliation to handle server-side lag for better synchronization
  • Player Movement Interpolation for smooth display of other players' actions
  • Expanding the Game World to create larger, more immersive arenas
  • Camera Logic for more intuitive navigation

Future Enhancements:

  • Collision Detection for player and object interactions
  • Food Generation & Snake Growth mechanics to introduce dynamic game elements
  • Leaderboard and UI Enhancements for better player experience

TODO:

  • Serve vue files from backend
  • POC - web socket server
  • Connect/disconnect player
  • Show statistics on client-side
  • POC - Render snake based on multiple coordinates (client-side)
  • POC - Player movement based on mouse coordinates (client-side)
  • Design authoritative server based on ticker
  • Server-side player movement
  • Adopt class-based design for client-side
  • Add support for ping calculation
  • Add client-side prediction for smooth and snappy player movement (client-side) (for now removed this)
  • Add server reconciliation to fix any server-side lag (client-side)
  • Add interpolation for smooth other player movement (client-side)
  • Make world as finite and with bigger dimension than current one
  • Add camera logic
  • Add collision detection logic
  • Create debug menu with features like teleport etc
  • Increase and decrease player speed on mousedown and mouseup events respectively
  • Improve snake spawn coordinates by considering world radius
  • Re-arch classes and create driver classes for better code readability and maintainability
  • Compensate snake speed by decreasing snake length
  • Detect collision with world boundary
  • Generate food on random coordinates
  • Food consumption logic and snake growth logic
  • Create chat system using SSE and channels
  • Leaderboard
  • Client UI design

Optimizations

  • Use of binary format instead of json
  • Stop rendering when tab is switched
  • Separate goroutine for calculating/processing game logic (if server struggle at current tick-rate)
  • Use of Pixi HTML 5 renderer engine
