Comprehensive practice of Go language game programming

The Go language is suitable for game programming due to its high performance and parallel processing capabilities. Getting started requires installing the Go SDK and IDE. The first game can be a simple text adventure, where you interact with the game by entering commands. For graphics-intensive games, the SDL2 library is required, which can help create complex pixel art games.

Comprehensive Practice of Go Language Game Programming

The Go language is favored by game developers for its high performance and parallel processing capabilities welcome. From simple text adventures to complex graphics-intensive games, the Go language provides a wealth of tools and libraries to build stunning gaming experiences.

Getting Started

To start using the Go language for game programming, you need to download and install the Go SDK (Software Development Kit). You can also use an IDE (Integrated Development Environment) like Visual Studio Code or GoLand to streamline the development process.

Build your first game

Let's start with a simple text adventure game. Create a file named adventure.go and enter the following code:

package main

import (
    "bufio"
    "fmt"
    "os"
)

func main() {
    reader := bufio.NewReader(os.Stdin)

    fmt.Println("Welcome to the adventure game!")

    // 主游戏循环
    for {
        fmt.Println("What do you want to do?")

        input, _ := reader.ReadString('\n')
        input = strings.TrimSpace(input)

        // 处理玩家输入
        switch input {
        case "north":
            fmt.Println("You go north.")
        case "south":
            fmt.Println("You go south.")
        case "east":
            fmt.Println("You go east.")
        case "west":
            fmt.Println("You go west.")
        case "quit":
            fmt.Println("Goodbye!")
            break
        default:
            fmt.Println("Invalid command.")
        }
    }
}

Run go run adventure.go to launch the game. You will see a command prompt instructing you to enter commands. Try typing "north", "south", or "quit" to experience the game.

Building graphics-intensive games

In order to build graphics-intensive games, you need to use the Go language's SDL2 (Simple Direct Media Layer) library. Install SDL2 and import it into your project:

// your_project_directory/
├── main.go
├── go.mod
└── vendor/
    └── github.com/veandco/go-sdl2

Build a simple pixel art game using the SDL2 library:

package main

import (
    "fmt"

    "github.com/veandco/go-sdl2/sdl"
)

const (
    windowWidth  = 640
    windowHeight = 480
)

func main() {
    // 初始化 SDL2
    if err := sdl.Init(sdl.INIT_EVERYTHING); err != nil {
        fmt.Println("Could not initialize SDL2:", err)
        return
    }
    defer sdl.Quit()

    // 创建窗口
    window, err := sdl.CreateWindow("Pixel Art Game", sdl.WINDOWPOS_UNDEFINED, sdl.WINDOWPOS_UNDEFINED, windowWidth, windowHeight, sdl.WINDOW_OPENGL)
    if err != nil {
        fmt.Println("Could not create window:", err)
        return
    }

    // 创建渲染器
    renderer, err := sdl.CreateRenderer(window, -1, sdl.RENDERER_ACCELERATED)
    if err != nil {
        fmt.Println("Could not create renderer:", err)
        return
    }

    // 设置绘制颜色
    renderer.SetDrawColor(255, 255, 255, 255)

    // 主游戏循环
    running := true
    for running {
        // 处理事件
        for event := sdl.PollEvent(); event != nil; event = sdl.PollEvent() {
            switch event.(type) {
            case *sdl.QuitEvent:
                running = false
            }
        }

        // 清除屏幕
        renderer.Clear()

        // 绘制像素艺术
        // ...

        // 更新屏幕
        renderer.Present()
    }
}

Run the game using go run main.go , you will see a window with pixel art drawn in it.
