怎么用C#实现拼图小游戏

这篇文章主要介绍“怎么用C#实现拼图小游戏”，在日常操作中，相信很多人在怎么用C#实现拼图小游戏问题上存在疑惑，小编查阅了各式资料，整理出简单好用的操作方法，希望对大家解答”怎么用C#实现拼图小游戏”的疑惑有所帮助！接下来，请跟着小编一起来学习吧！

1.首先布置好界面。

标题栏，菜单栏，状态栏，以及放置图片框的panel。

2.定义图片框类

/// <summary>
/// 图片框类，包含虚拟XY位置
/// </summary>
public class PictureBoxEx : PictureBox
    {
        private Point _xy ;
        private Point _inxy;
 
        /// <summary>
        /// 初始XY位置
        /// </summary>
        public Point inxy
        {
            get { return _inxy; }
           // set { _inxy = value; }
        }
 
        /// <summary>
        /// 当前XY位置
        /// </summary>
        public Point xy
        {
            get { return _xy; }
            set { _xy = value; }
        }
 
        public PictureBoxEx(Point txy)
            : base()
        {
            _inxy=_xy = txy;
        }
 
        /// <summary>
        /// 判断是否回到初始位置
        /// </summary>
        /// <returns>true：回到初始位置</returns>
        public bool judge() {
            return (_xy.X == _inxy.X) && (_xy.Y == _inxy.Y);
        }
    }

每个分割的图片都是PictureBoxEx对象，保存在list或者矩阵中。

3.载入图片，随机乱序排布

/// <summary>
/// 生成PictureBoxEx ,排布在panel上
/// </summary>
/// <param name="img">原图</param>
/// <param name="random">是否打乱显示</param>
private void initPbx(Image img, bool random)
        {
            pbxs.Clear();//清除图片框列表
            panelMain.Controls.Clear();//清除panel包含的控件
 
            byte[] rands = new byte[column*row] ; //保存随机乱序一维数组
            if (random)
            {
                try
                {
                     generateDisorderArray(ref rands);
                }
                catch
                {
                    MessageBox.Show("生成乱序错误！");
                }
            }
       
            srcBmp = new Bitmap(srcImg);
            Size rbmpSize = new System.Drawing.Size(srcBmp.Width / column, srcBmp.Height / row);
            int bw = srcBmp.Width / column, bh = srcBmp.Height / row;
            int rw = panelMain.ClientSize.Width / column, rh = panelMain.ClientSize.Height / row;
            int cnt = 0;
            for (int i = 0; i < column; i++)//行
            {
                pbxs.Add( new  List<PictureBoxEx>() );
                for (int j = 0; j < row; j++)//列
                { 
                    PictureBoxEx pb = new PictureBoxEx( new Point(i,j));
                    pb.Size = new System.Drawing.Size(rw,rh);
                    pb.BorderStyle = BorderStyle.None;
                    pb.Dock = DockStyle.None;
                    pb.BackgroundImageLayout = ImageLayout.Stretch;
                    panelMain.Controls.Add(pb);
                    pb.Location = new Point(rw*i,rh*j);
                    pbxs[i].Add(pb);
                  
                    Bitmap tbmp = new Bitmap(rw, rh);
                    Graphics g = Graphics.FromImage(tbmp);
                    Point bmppt;
                    if (random)
                    {
                        //一维转二维
                        int ri = rands[cnt] % column;
                        int rj = (rands[cnt] / column) % row;
                        bmppt = new Point(bw * ri, bh * rj);
                        pb.xy = new Point(ri, rj);
                        cnt++;
                    }
                    else
                    {
                        bmppt = new Point(bw * i, bh * j);
                    }
                    g.DrawImage(srcBmp, pb.ClientRectangle, new Rectangle( bmppt , rbmpSize), GraphicsUnit.Pixel);
                    g.DrawRectangle(  Pens.Red ,pb.ClientRectangle);
                    if (!random)
                    {
                        g.DrawString(pb.xy.ToString(), new Font(System.Drawing.SystemFonts.DefaultFont.Name, 10),new SolidBrush(Color.Red), new PointF(1.0f, 1.0f));
                    }
                    g.Dispose();
                    pb.BackgroundImage = tbmp;
                    //为实现拖动图片，加入3个鼠标事件函数
                    pb.MouseDown += new MouseEventHandler(pb_MouseDown);
                    pb.MouseMove += new MouseEventHandler(pb_MouseMove);
                    pb.MouseUp += new MouseEventHandler(pb_MouseUp);
 
                    if (random)
                    {
                        isStartGame = true;
                        lab_canplay.BackColor = Color.Green;
                    }
                    else {
                        isStartGame = false;
                        lab_canplay.BackColor = Color.Red;
                    }
                }
            }
        }

生成随机乱序数组函数：单纯的随机数组是不行的，因为随机不一定乱序。

/// <summary>
/// 生成随机乱序数组,洗牌 FisherYates Shuffle
/// 随机不一定无序，所以还需要检查无序的度
/// </summary>
public void generateDisorderArray(ref byte[] arr )
        {
            byte len = (byte)arr.Length;
            if (len == 1U)
            {
                arr[0] = 0;
            }
            else
            if (len == 2U)
            {
                arr[0] = 1; arr[1] = 0;
            }
            else
            {
                for (byte i = 0; i < len; i++)
                {
                    arr[i] = i;
                }
 
                byte[] rands = new byte[len * 4];
                rng.GetBytes(rands);
                
                for (int j = len-1; j >=0; j--)
                {
                    int idx = (int)(BitConverter.ToUInt32(rands, j * 4) % (byte)(j + 1));
                    SwapValue<byte>(ref arr[idx], ref arr[j]);
                }
                //下面简单检查无序度
                List<byte> defs = new  List<byte>();
                for (byte a=0; a < len;a++ )
                {
                    if (a == arr[a]) defs.Add(a); //记录位置
                }
                //有一半在原位置，则不够无序，首尾换位
                if ( defs.Count > 1 && defs.Count >= (len/2) ) 
                {
                    for (byte i = 0; i < defs.Count/2; i++)
                    {
                        SwapValue<byte>(ref arr[defs[i]], ref arr[defs[defs.Count - 1 - i]]);
                    }
                }
            }
        }
 
        /// <summary>
        /// 交换数值
        /// </summary>
        /// <typeparam name="T"></typeparam>
        /// <param name="a"></param>
        /// <param name="b"></param>
        public static void SwapValue<T>(ref T a, ref T b)
        {
            T temp=a ;
            a=b ;
            b=temp ;
        }

4.图片拖动交换

/// <summary>
/// 交换图片，位置信息
/// </summary>
/// <param name="srcXY">源位置</param>
/// <param name="dstXY">目的位置</param>
private void SwapPbx(Point srcXY, Point dstXY)
        {
            PictureBoxEx pba = pbxs[srcXY.X ][ srcXY.Y];
            PictureBoxEx pbb = pbxs[dstXY.X ][ dstXY.Y];
            if (srcXY.X == dstXY.X && srcXY.Y == dstXY.Y)
            {
                pba.Location = startloc;
            }
            else
            {
                pba.Location = startloc;
                var img = pba.BackgroundImage;
                pba.BackgroundImage =  pbb.BackgroundImage ;
                pbb.BackgroundImage = img;
 
                var temp = pba.xy;
                pba.xy = pbb.xy;
                pbb.xy = temp;
            }
        }
 
        /// <summary>
        /// 像素点位置转化为虚拟XY坐标
        /// </summary>
        /// <param name="pt">像素点位置</param>
        /// <param name="sz">所在的范围</param>
        /// <returns>虚拟XY坐标</returns>
        private Point PointToXY(Point pt, Size sz)
        {
            Size s = sz;
            Point p = pt;
            int rw = s.Width / column;
            int rh = s.Height / row;
            return new Point(p.X / rw, p.Y / rh);
        }

三个鼠标事件函数

private void pb_MouseUp(object sender, MouseEventArgs e)
  {
            if (isDrag)
            {
                isDrag = false;
                Point upxy = PointToXY(((Control)sender).Parent.PointToClient(Control.MousePosition), ((Control)sender).Parent.Size);
                SwapPbx(startxy, upxy);
                gameSteps++;
                toolStripLab_Step.Text = "步数：" + gameSteps;
                {
                    if (judgeResult(pbxs))//拼图OK
                    {
                        
                        toolStripLab_Tip.Text = "完成拼图";
                        DialogResult res = new FormOK( "完成拼图！\r使用步数:" + gameSteps ).ShowDialog();
                        
                        if (res ==  DialogResult.Abort)
                        {
                            this.Close();
                        }
                        else if (res ==  DialogResult.OK)
                        {
                            if (srcImg != null)
                            {
                                initPbx(srcImg, true);
                                isStartGame = true;
                                
                            }
                        }
                        enableNumud(true);
                        gameSteps = 0;
                        
                    }
                }
            } 
        }
 
        private void pb_MouseMove(object sender, MouseEventArgs e)
        {
            if (e.Button == MouseButtons.Left && isDrag)
            {
                Point mousePos = Control.MousePosition;
                mousePos.Offset(mouse_offset.X, mouse_offset.Y);
                ((Control)sender).Location = ((Control)sender).Parent.PointToClient(mousePos);
            }
        }
 
        private void pb_MouseDown(object sender, MouseEventArgs e)
        {
            if (e.Button == MouseButtons.Left && pbxs.Count > 0 && isStartGame )
            {
                isDrag = true;
                enableNumud( false );
                startloc = ((Control)sender).Location;
                mouse_offset = new Point(-e.X, -e.Y);
                ((Control)sender).BringToFront();
 
                Point pp = ((Control)sender).Parent.PointToClient(Control.MousePosition);
                startxy = PointToXY(pp, ((Control)sender).Parent.Size);
            }
        }

5.判断是否成功

/// <summary>
/// 判断是否成功
/// </summary>
/// <param name="pbxs">图片矩阵</param>
/// <returns>是否归位了</returns>
private bool judgeResult(List<List<PictureBoxEx>> pbxs)
        {
            bool res = true;
            foreach (var i in pbxs)
            {
                foreach (var j in i)
                {
                    if (!j.judge()) { res = false; return res; }
                }
            }
            return res;
        }
