Crazy Car is a networked multiplayer racing game solution built with Unity, targeting game developers looking to create custom online racing experiences. It provides a comprehensive architecture and core features like hot-swapping, matchmaking, and backend management, enabling rapid development of genre-specific titles.

How It Works

The game client utilizes QFramework for architecture, Addressable for asset management, and HybridCLR for hot-swapping C# code. Networking is supported via KCP and WebSocket. The backend comprises a Spring Boot and Mybatis Plus server for game logic and data persistence, with a Vue.js and Element UI frontend for administration. This modular approach allows for flexibility and efficient updates.
