C#拼图游戏编写代码(2)

下面详细讲解如何编写C#拼图游戏的代码，具体分为以下步骤：

1. 创建WinForm窗口

代码中首先需要创建一个WinForm窗口，作为整个游戏的主界面。

public partial class FormMain : Form
{
    public FormMain()
    {
        InitializeComponent();
    }
}

2. 添加拼图图片并进行切割

接下来需要添加一张图片作为拼图的背景，并将图片切割成多个小块。这里以2*2的拼图为例，将图片分成四个等大的小块。

// 加载图片
Image img = Image.FromFile("background.jpg");

// 计算小块大小
int blockHeight = img.Height / 2;
int blockWidth = img.Width / 2;

// 将图片按照小块切割，并保存到List<Image>中
List<Image> imgBlockList = new List<Image>();
for (int j = 0; j < 2; j++)
{
    for (int i = 0; i < 2; i++)
    {
        RectangleF cloneRect = new RectangleF(i * blockWidth, j * blockHeight, blockWidth, blockHeight);
        PixelFormat format = img.PixelFormat;
        Image cloneBitmap = ((Bitmap)img).Clone(cloneRect, format);
        imgBlockList.Add(cloneBitmap);
    }
}

3. 准备拼图区域

接下来需要创建一个Panel控件，用于显示拼图的区域，并将小块添加到Panel中，形成起始的拼图布局。

// 创建Panel控件
Panel imagePanel = new Panel();
imagePanel.Width = blockWidth * 2;
imagePanel.Height = blockHeight * 2;
imagePanel.Location = new Point(10, 10);
imagePanel.BorderStyle = BorderStyle.FixedSingle;
this.Controls.Add(imagePanel);

// 将小块添加到Panel中
int index = 0;
for (int j = 0; j < 2; j++)
{
    for (int i = 0; i < 2; i++)
    {
        PictureBox pictureBox = new PictureBox();
        pictureBox.Size = new Size(blockWidth, blockHeight);
        pictureBox.Location = new Point(i * blockWidth, j * blockHeight);
        pictureBox.Image = imgBlockList[index];
        pictureBox.Tag = index;
        pictureBox.Click += PictureBox_Click;
        imagePanel.Controls.Add(pictureBox);
        index++;
    }
}

4. 实现小块交换逻辑

接下来需要实现小块之间交换的逻辑。这里使用PictureBox控件来表示小块，存储小块图像的序号（0-3）。

private PictureBox lastClickBox = null;
private void PictureBox_Click(object sender, EventArgs e)
{
    PictureBox clickBox = sender as PictureBox;
    if (lastClickBox == null)
    {
        lastClickBox = clickBox;
    }
    else
    {
        int lastIndex = (int)lastClickBox.Tag;
        int currentIndex = (int)clickBox.Tag;

        // 交换序号
        lastClickBox.Tag = currentIndex;
        clickBox.Tag = lastIndex;

        // 交换图像
        Image temp = lastClickBox.Image;
        lastClickBox.Image = clickBox.Image;
        clickBox.Image = temp;

        lastClickBox = null;
    }
}

5. 添加计时器和计分功能

最后，在游戏界面上添加一个计时器和计分功能，实现游戏计时和计分的功能。游戏计时和计分的具体实现方法因游戏而异，这里不做过多讲解。

private void timer1_Tick(object sender, EventArgs e)
{
    // 更新计时器
}

private void updateScore(int score)
{
    // 更新计分
}

至此，我们已经完成了拼图游戏的代码编写，可以通过Visual Studio等IDE调试和运行。下面是完整代码的示例：

public partial class FormMain : Form
{
    private List<Image> imgBlockList;
    private int blockHeight;
    private int blockWidth;
    private PictureBox lastClickBox = null;
    private int score = 0;

    public FormMain()
    {
        InitializeComponent();

        // 加载图片
        Image img = Image.FromFile("background.jpg");

        // 计算小块大小
        blockHeight = img.Height / 2;
        blockWidth = img.Width / 2;

        // 将图片按照小块切割，并保存到List<Image>中
        imgBlockList = new List<Image>();
        for (int j = 0; j < 2; j++)
        {
            for (int i = 0; i < 2; i++)
            {
                RectangleF cloneRect = new RectangleF(i * blockWidth, j * blockHeight, blockWidth, blockHeight);
                PixelFormat format = img.PixelFormat;
                Image cloneBitmap = ((Bitmap)img).Clone(cloneRect, format);
                imgBlockList.Add(cloneBitmap);
            }
        }

        // 创建Panel控件
        Panel imagePanel = new Panel();
        imagePanel.Width = blockWidth * 2;
        imagePanel.Height = blockHeight * 2;
        imagePanel.Location = new Point(10, 10);
        imagePanel.BorderStyle = BorderStyle.FixedSingle;
        this.Controls.Add(imagePanel);

        // 将小块添加到Panel中
        int index = 0;
        for (int j = 0; j < 2; j++)
        {
            for (int i = 0; i < 2; i++)
            {
                PictureBox pictureBox = new PictureBox();
                pictureBox.Size = new Size(blockWidth, blockHeight);
                pictureBox.Location = new Point(i * blockWidth, j * blockHeight);
                pictureBox.Image = imgBlockList[index];
                pictureBox.Tag = index;
                pictureBox.Click += PictureBox_Click;
                imagePanel.Controls.Add(pictureBox);
                index++;
            }
        }

        // 添加计时器
        Timer timer = new Timer();
        timer.Interval = 1000;
        timer.Tick += timer1_Tick;
        timer.Start();
    }

    private void PictureBox_Click(object sender, EventArgs e)
    {
        PictureBox clickBox = sender as PictureBox;
        if (lastClickBox == null)
        {
            lastClickBox = clickBox;
        }
        else
        {
            int lastIndex = (int)lastClickBox.Tag;
            int currentIndex = (int)clickBox.Tag;

            // 交换序号
            lastClickBox.Tag = currentIndex;
            clickBox.Tag = lastIndex;

            // 交换图像
            Image temp = lastClickBox.Image;
            lastClickBox.Image = clickBox.Image;
            clickBox.Image = temp;

            // 计分
            score++;
            updateScore(score);

            lastClickBox = null;
        }
    }

    private void timer1_Tick(object sender, EventArgs e)
    {
        // 更新计时器
    }

    private void updateScore(int score)
    {
        // 更新计分
    }
}
