程序设计 之 C#实现《拼图游戏》 （上）代码篇

原理详解请参考博客中

拼图游戏（下）原理篇 http://www.cnblogs.com/labixiaohei/p/6713761.html

 

 

 

 

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

--------------------------------------------------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

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 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

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）
