如何利用C#编写拼图游戏

如何利用C#编写拼图游戏？相信很多没有经验的人对此束手无策，为此本文总结了问题出现的原因和解决方法，通过这篇文章希望你能解决这个问题。

功能描述：

　　1.用户自定义上传图片

　　2.游戏难度选择：简单（3*3）、一般（5*5）、困难（9*9）三个级别

　　3.纪录完成步数

模块：

　　1.拼图类

　　2.配置类

　　3.游戏菜单窗口

　　4.游戏运行窗口

代码文件VS2013版本:

--------------------------------------------------我叫分割线---------------------------------------------------------------

1.拼图类

方法：

　　1.构造函数：传图片并分割成一个一个小图片

　　2.交换方法

　　3.大图中截取小单元方法

　　4.移动单元的方法

　　5.打乱单元顺序方法

  }

 }

 }
 }

 

 }
}

2、配置类：

using System;
using System.Collections.Generic;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace 拼图
{
 public static class GamePage
 {
 public static Puzzle.Diff Dif; //游戏难度
 public static Image img; //拼图图案
 }
}

游戏菜单：

通过菜单，上传图片至配置类img，并选择难度上传至配置类Dif，然后拼图对象构造时读取配置类

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;

namespace 拼图
{
 public partial class Menu : Form
 {
 public Menu()
 {
 InitializeComponent();
 GamePage.img =Image.FromFile(@"Image\\拼图.jpg");
 Control.CheckForIllegalCrossThreadCalls = false;
 }

 private void button1_Click(object sender, EventArgs e)
 {
 GamePage.Dif = Puzzle.Diff.simple;
 this.Hide();
 Form1 ff = new Form1();
 ff.closefather+=new 拼图.Form1.childclose(this.closethis); 
 ff.Show();
 
 }

 private void button2_Click(object sender, EventArgs e)
 {
 GamePage.Dif = Puzzle.Diff.ordinary;
 this.Hide();
 Form1 ff = new Form1();
 ff.closefather += new 拼图.Form1.childclose(this.closethis); 
 ff.Show();
 
 }

 private void button3_Click(object sender, EventArgs e)
 {
 GamePage.Dif = Puzzle.Diff.difficulty;
 this.Hide();
 Form1 ff = new Form1();
 ff.closefather += new 拼图.Form1.childclose(this.closethis); 
 ff.Show();
 
 }

 public void closethis()
 {
 this.Show();
 }


 private void button4_Click(object sender, EventArgs e)
 {
 OpenFileDialog ofd = new OpenFileDialog();
 ofd.ShowDialog();
 GamePage.img = Image.FromFile(ofd.FileName).GetThumbnailImage(600,600,new Image.GetThumbnailImageAbort(delegate { return false; }), IntPtr.Zero); 

 }
 private void Menu_Load(object sender, EventArgs e)
 {
 }

 }
}

游戏运行窗口：

1.注册鼠标点击事件来获得输入消息

2.显示功能

3.pictureBox1用来展示游戏拼图情况

4.pictureBox2展示完整拼图的缩略图（当鼠标移至pictureBox2时，发送消息，使pictureBox1显示完整拼图）

5.Numlabel来显示移动步数（通过变量Num的累加来计算）

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading;
using System.Threading.Tasks;
using System.Windows.Forms;

namespace 拼图
{
 public partial class Form1 : Form
 {
 public Form1()
 {
 InitializeComponent();
 }
 private Puzzle puzzle;
 private int Num=0;
 private Image img;
 private void Form1_Load(object sender, EventArgs e)
 {
 img = GamePage.img;
 pictureBox2.Image = img.GetThumbnailImage(120,120, new Image.GetThumbnailImageAbort(delegate { return false; }), IntPtr.Zero);
 puzzle = new Puzzle(img, 600, GamePage.Dif);
 pictureBox1.Image =puzzle.Display();
 }

 private void pictureBox1_MouseClick(object sender, MouseEventArgs e)
 {
 if (puzzle.Move(e.X / (puzzle.Width / puzzle.N), e.Y / (puzzle.Width / puzzle.N)))
 {
 Num++;
 pictureBox1.Image = puzzle.Display();
 if (puzzle.Judge())
 { 
  if (MessageBox.Show("恭喜过关", "是否重新玩一把", MessageBoxButtons.OKCancel) == DialogResult.OK)
  {
  Num = 0;
  puzzle.Upset();
  pictureBox1.Image = puzzle.Display();
  
  }
  else
  {
  Num = 0;
  closefather();
  this.Close();
  }

 }

 }
 NumLabel.Text = Num.ToString();
 }

 private void pictureBox2_MouseEnter(object sender, EventArgs e)
 {
 pictureBox1.Image = img;
 }

 private void pictureBox2_MouseLeave(object sender, EventArgs e)
 {
 pictureBox1.Image = puzzle.Display();
 }


 private void Form1_FormClosed(object sender, FormClosedEventArgs e)
 {
 closefather();
 }
 public delegate void childclose();
 public event childclose closefather;

 }
}
