C#实现拼图游戏

本文实例为大家分享了C#实现拼图游戏的具体代码，供大家参考，具体内容如下

（一）需求：（这个需求书写较为简单）

• 图片：有图
• 切割：拼图不是一个图，我们需要把一个整图它切割成N*N的小图
• 打乱：把这N*N的小图打乱顺序，才能叫拼图qwq
• 判断：判断拼图是否成功
• 交互：选择鼠标点击拖动的方式
• 展示原图：拼不出来可以看看
• 更换图片：腻了可以从本地选择一张你喜欢的来拼图
• 选择难度：除了2×2还可以选择切割成3×3或者4×4，看你喜欢qwq

（二）设计：

使用VS的c#来实现

界面设计：picturebox控件来显示图片，button控件来实现按钮点击的各类事件：图片重排、换图、查看原图等，使用numericUpDown控件来控制切割的边数。如下图：

把要拼的图片放进resource文件里
设计函数，使用cutpicture类来切割图片

ps：挑战模式貌似有点小问题，没法显示倒数的时间在页面上，体验感觉不好。

接下来是设计显示原图的页面，只需要一个picturebox即可，代码如下：

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 拼图游戏
{
    public partial class Form_Original : Form
    {
        public string picpath;
        public Form_Original()
        {
            InitializeComponent();
        }

        private void pic_Original_Click(object sender, EventArgs e)
        {

        }

        private void Form_Original_Load(object sender, EventArgs e)
        {
            pic_Original.Image = CutPicture.Resize(picpath, 600, 600);
        }
    }
}

以上就是本文的全部内容，希望对大家的学习有所帮助，也希望大家多多支持我们。
