QQ游戏美女找茬外挂

         前段时间看到别人玩QQ游戏，美女来找茬，突然之间想到自己可以做个小外挂，自动比较两幅图，把不同之处标出来。软件自动化测试和开发简单的游戏外挂很相似。都是控制UI，然后模拟键盘和鼠标操作

 

 

思路：

 

1.    把 "美女找茬“ 中的两幅画截出来。

2.    对比两幅画，把不同之处标出来。

 

我们只需要图片在屏幕上的坐标和大小就可以截图了，根据分析图片大小在高度：490， 宽度：440 比较合适

 

截图的方法为： 

 

        public static int height = 490;        public static int width = 440;

        public static void CaptureScreenToFile(int left, int right, string fileName)        {            Bitmap image = new Bitmap(height, width);            Graphics g = Graphics.FromImage(image);            g.CopyFromScreen(left, right, 0, 0, image.Size);            image.Save(fileName);        }

 

另外，我们还需要知道图片所在的坐标。 坐标为游戏窗口的坐标+图片在游戏窗口中的位移

为了获取游戏窗口的坐标我们需要使用2个Win32API函数

 

 

        [StructLayout(LayoutKind.Sequential)]        public struct RECT        {            public int left;            public int top;            public int right;            public int bottom;        }

        [DllImport("user32.dll", EntryPoint = "FindWindow", CharSet = CharSet.Auto)]        public static extern IntPtr FindWindow(string lpClassName, string lpWindowName);

 

        [DllImport("user32.dll")]        public static extern IntPtr GetWindowRect(IntPtr hWnd, ref RECT rect);

 

 

 

public Win32API.RECT Pos = new Win32API.RECT();

 

        public void SetPos()        {            IntPtr window = Win32API.FindWindow("#32770", "大家来找茬");

            Win32API.GetWindowRect(window, ref Pos);        }

 

 

调用SetPos()方法后，就能获取游戏窗口的位置，保存在Pos里。

 

 然后我们截2张图

 

 CaptureScreenToFile(12 + Pos.left, 196 + Pos.top, firstImage);

CaptureScreenToFile(521 + Pos.left, 196 + Pos.top, secondImage);

 

 

最后一步就是比较2副图片的不同了，  很简单，逐个像素比较，不同的就用红色表示出来

 

        public static void Compare(string firstImagePath, string secondImagePath, string DifImagePath)        {            Bitmap firstImage = new Bitmap(firstImagePath, true);            Bitmap secondImage = new Bitmap(secondImagePath, true);            Bitmap thirdImage = new Bitmap(height, width);

            string firstPixel;            string secondPixel;

            if (firstImage.Width == secondImage.Width && firstImage.Height == secondImage.Height)            {                for (int i = 0; i < firstImage.Width; i++)                {                    for (int j = 0; j < firstImage.Height; j++)                    {                        firstPixel = firstImage.GetPixel(i, j).ToString();                        secondPixel = secondImage.GetPixel(i, j).ToString();                        if (firstPixel != secondPixel)                        {                            thirdImage.SetPixel(i, j, Color.Red);                                                        }                        else                        {                            thirdImage.SetPixel(i, j, firstImage.GetPixel(i, j));                        }                    }                }            }

            firstImage.Dispose();            secondImage.Dispose();

            thirdImage.Save(DifImagePath);            thirdImage.Dispose();        }

 

运行效果:
