Unleash game creativity with Go language

The Go language is known for its simplicity and concurrency, making it ideal for developing interactive games . This guide will guide you through creating a simple 2D game using the Go language.

Installing Go

First, install the Go language on your system. Go to the [Go official website](https://go.dev/) to download the installer for your platform.

Create a Go project

Create a directory to store your game project, such as mygame. Then use the go mod init command to initialize a Go module:

cd mygame
go mod init mygame

Create a game engine

We will create a simple game engine to handle graphics and input. Create the engine.go file and add the following code:

package main

import (
    "fmt"
    "image"
    "image/color"

    "github.com/hajimehoshi/ebiten/v2"
)

// 游戏状态
type GameState int

const (
    GameStateRunning GameState = iota
    GameStatePaused
    GameStateOver
)

// 游戏引擎
type GameEngine struct {
    State GameState

    window *ebiten.Window
}

// 初始化引擎
func (e *GameEngine) Init() error {
    // 创建 Ebiten 窗口
    var err error
    e.window, err = ebiten.NewWindow("我的游戏", 640, 480, 0)
    return err
}

// 更新游戏状态
func (e *GameEngine) Update() error {
    switch e.State {
    case GameStateRunning:
        // 处理游戏逻辑
    case GameStatePaused:
        // 暂停游戏
    case GameStateOver:
        // 游戏结束
    }
    return nil
}

// 绘制游戏
func (e *GameEngine) Draw(screen *image.RGBA) {
    // 清除屏幕
    screen.Fill(color.White)

    // 绘制游戏对象
}

// 处理键盘输入
func (e *GameEngine) HandleInput() error {
    // 获取键盘输入
    return nil
}

// 运行游戏循环
func (e *GameEngine) Run() error {
    for {
        e.window.Update()
        if e.window.IsClosed() {
            break
        }

        if err := e.Update(); err != nil {
            return err
        }

        if err := e.Draw(e.window.Image()); err != nil {
            return err
        }

        if err := e.HandleInput(); err != nil {
            return err
        }
    }
    return nil
}

Create Game Object

Now, let’s create a simple game object. Create the player.go file and add the following code:

package main

import (
    "image"

    "github.com/hajimehoshi/ebiten/v2"
)

// 玩家对象
type Player struct {
    image *ebiten.Image
    x, y int
}

// 创建玩家对象
func NewPlayer(x, y int) *Player {
    return &Player{
        image: ebiten.NewImage(16, 16),
        x: x,
        y: y,
    }
}

// 更新玩家对象
func (p *Player) Update() {
    // 处理玩家逻辑
}

// 绘制玩家对象
func (p *Player) Draw(screen *image.RGBA) {
    // 绘制玩家
}

Copy after login

Main Game Program

Finally, we have main.go Write the main game program in the file:

package main

import (
    "log"
)

func main() {
    // 创建游戏引擎
    engine := &GameEngine{}
    if err := engine.Init(); err != nil {
        log.Fatal(err)
    }

    // 创建玩家对象
    player := NewPlayer(100, 100)

    // 初始化游戏
    engine.State = GameStateRunning

    // 运行游戏循环
    if err := engine.Run(); err != nil {
        log.Fatal(err)
    }
}

Copy after login

Run the game

Run in the terminalgo run main.go to start the game.
