Practical cases of golang framework in game development

Practical cases of Go framework in game development: Technology stack: Go v1.18, Gin framework, MongoDB architecture: Web server (processing HTTP requests), game server (processing game logic and communication), MongoDB database (storing players Data) Web server: Use Gin routing to handle player creation and acquisition requests Game server: Handle game logic and player communication, use UNIX sockets for network communication Database: Use MongoDB to store player data, provide functions for creating and obtaining player information Practical cases Functions: Create players, obtain players, update player status, handle player interactions Conclusion: The Go framework provides efficient

Practical cases of the Go framework in game development

Go has received widespread attention in the field of game development due to its excellent concurrency and high-performance features. The following is a practical case of using the Go framework to build a multi-player game server:

Technology Stack

• Go v1.18
• Gin Web Framework
• MongoDB database

Architecture

The game server architecture is as follows:

+----------------+
| Web 服务器      |

Code snippet

Web Server

Gin routing for handling HTTP requests:

func main() {
    router := gin.Default()

    router.POST("/create-player", createPlayer)
    router.GET("/get-player", getPlayer)

    router.Run()
} func createPlayer(c *gin.Context) {
    // 处理创建玩家请求
}func getPlayer(c *gin.Context) {
    // 处理获取玩家请求
}

Game Server
Game Server Handle game logic and player communication:

func main() {
    // 创建游戏世界
    world := game.NewWorld()

    // 创建网络服务器
    server := net.ListenUnix("unix", &net.UnixAddr{Name: "/tmp/game.sock", Net: "unix"})
    for {
        conn, err := server.Accept()
        if err != nil {
            log.Fatal(err)
        }
        go handleConn(conn, world)
    }
}

func handleConn(conn net.Conn, world *game.World) {
    // 处理玩家连接并传递消息
}

Database
Use MongoDB to store player data:

type Player struct {
    ID       string `bson:"_id"`
    Name     string
    Level    int
}

func createPlayer(player *Player) error {
    _, err := collection.InsertOne(ctx, player)
    return err
}

func getPlayer(id string) (*Player, error) {
    var player Player
    err := collection.FindOne(ctx, bson.M{"_id": id}).Decode(&player)
    return &player, err
}

Practical case

This game server provides the following functions:

• Create and obtain players
• Update player status in the game
• Handle interactions between players

Conclusion

The Go framework can simplify the game development process by providing efficient and scalable solutions. This practical example shows how to build a multiplayer game server using Go, which can be used as a starting point for building more complex games.
