Unleash game creativity with Go language

To create a 2D game using Go language, follow the following steps: Install Go language. Create a project directory and initialize the Go module. Create a game engine to handle graphics and input. Create a game object. Write the main game program. run game.

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
}

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)
    }
}

Run the game

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