Agar Chungus

Agar Chungus is a fast-paced, multiplayer web game inspired by the viral hit Agar.io. In this game, players control a cell in a competitive arena with one simple goal: consume smaller cells and pellets to grow larger while avoiding being eaten by bigger players. It captures the classic "eat-or-be-eaten" mechanics that made the .io genre famous, providing a smooth, browser-based experience for competitive play.

Based on the architecture of the rybealey/agar repository, the game is built using a modern JavaScript stack designed for low-latency real-time interaction.

Technologies Used

• Node.js & Express: The backend is powered by Node.js, providing a scalable environment to handle multiple concurrent game sessions. Express is used to serve the game assets and manage server-side routing.
• Socket.io: This is the core engine for the game’s multiplayer functionality. It enables real-time, bi-directional communication between the server and the clients, ensuring that cell movements and "eats" are synchronized across all players with minimal lag.
• HTML5 Canvas: The game’s graphics are rendered using the HTML5 Canvas API. This allows for high-performance 2D rendering directly in the browser without the need for external plugins, enabling smooth movement for dozens of entities on screen.
• JavaScript (ES6+): The game logic—ranging from collision detection and cell physics to the "split" and "eject mass" mechanics—is written in clean, modern JavaScript.
• CSS3: Used for the UI overlay, menus, and responsive design elements to ensure the game is playable across different screen sizes.

The project is a great example of using WebSockets to create a high-stakes multiplayer environment entirely within a web browser.
