贪吃蛇大作战单人版完整代码以及详细解释

贪吃蛇总结：

1. 创建WPF应用程序

 

2. 添加Canvas标签。Name=back；

 

3. 添加loaded事件

 

4. 在loaded事件中创建蛇（设置蛇的位置，大小，颜色）

  this.Left = 0;

            this.Top = 0;

            this.Width  = 800;

            this.Height = 600;

            for (int i = 0; i < 5; i++)

            {

                bd = new Border();

                bd.Width = bd.Height = 10;

                bd.CornerRadius = new CornerRadius(5);

                if (i == 0)

                    bd.Background = Brushes.Red;

                else

                    bd.Background = Brushes.Black;

                Canvas.SetTop(bd,200+i*bd.Height);

                Canvas.SetLeft(bd,200);

                back.Children.Add(bd);

                snake.Add(bd);

 

5. 添加一个timer，（问题：添加timer和winform程序中不一样

Winform 程序中直接添加。

WPF应用程序中不能直接添加，需要引入命名空间：

Using System.Thearing

）

DispatcherTimer tm1 = new DispatcherTimer();

            tm1.Interval =TimeSpan.FromMilliseconds(200);

            tm1.Tick += Tm1_Tick;

            tm1.Start();

            this.KeyDown += MainWindow_KeyDown;

6. 添加键盘事件，读取键盘敲下的字符

 if (e.Key==Key.Up&&str!="d" )

            {

                str = "up";

            }

            if (e.Key==Key.Down&&str!="up")

            {

                str = "d";

         if(e.key-key.left&&str!="r")

            {

                str = "l";

            }

            if (e.Key == Key.Right&&str!="l")

            {

                str = "r";

            }

 

7.在timer事件中实现蛇的移动（问题：在实现向左移动时出现错误

解决：添加一个集合，来存储蛇的位置信息，与此同时添加一个border储存位置信息border）

 

        //创建蛇的位置集合

        List<Border> snakeback =new List<Border>();

 //创建蛇的位置border

                Border bdback = new Border();

                bdback.Height = bdback.Width = 10;

                Canvas.SetTop(bdback, 200 + i * bd.Height);

                Canvas.SetLeft(bdback, 200);

                snakeback.Add(bdback);

if (str == "up")

            {

                Canvas.SetTop(snake[0],Canvas.GetTop(snake[0]) - snake[0].Height);

                run();

            }

            if (str=="d")

            {

                Canvas.SetTop(snake[0],Canvas.GetTop(snake[0])+ snake[0].Height);

                run();

            }

            if (str == "l")

            {

                Canvas.SetLeft(snake[0],Canvas.GetLeft(snake[0]) - snake[0].Height);

                run();

            }

            if (str == "r")

            {

                Canvas.SetLeft(snake[0],Canvas.GetLeft(snake[0]) + snake[0].Height);

                run();

            }

 

private void run()

        {

            for (int i = 1; i < snake.Count; i++)

            {

                Canvas.SetTop(snake[i],Canvas.GetTop(snakeback[i - 1]));

                Canvas.SetLeft(snake[i],Canvas.GetLeft(snakeback[i - 1]));

            }

            for (int i = 0; i < snake.Count; i++)

            {

                Canvas.SetTop(snakeback[i],Canvas.GetTop(snake[i]));

                Canvas.SetLeft(snakeback[i],Canvas.GetLeft(snake[i]));

            }

        }

 

8. 判断与食物相撞时，食物改变位置

 if (Canvas.GetTop(snake[0])==Canvas.GetTop(food)&&Canvas.GetLeft(snake[0])==Canvas.GetLeft(food))

            {

                Canvas.SetTop(food, ra.Next(60) * 10);

                Canvas.SetLeft(food, ra.Next(80) * 10);

}

9. 在与食物相撞时添加一节蛇尾

10. 添加一个border来作为蛇尾，添加到snake集合中

11. 添加一个border存储所增加的蛇尾的位置信息

if (Canvas.GetTop(snake[0])==Canvas.GetTop(food)&&Canvas.GetLeft(snake[0])==Canvas.GetLeft(food))

            {

                Canvas.SetTop(food, ra.Next(60) * 10);

                Canvas.SetLeft(food, ra.Next(80) * 10);

                //定义一个增加的蛇尾的border

                Border bdfood = new Border();

                bdfood.Height = bdfood.Width = 10;

                bdfood.CornerRadius = new CornerRadius(5);

                bdfood.Background = Brushes.Azure;

                Canvas.SetTop(bdfood,Canvas.GetTop(snake[snake.Count-1]));

                Canvas.SetLeft(bdfood,Canvas.GetLeft(snake[snake.Count - 1]));

                back.Children.Add(bdfood);

                snake.Add(bdfood);

 

                //定义一个border存储增加的的集合

                Border br = new Border();

                br.Height = br.Width = 10;

                Canvas.SetTop(br, Canvas.GetTop(snakeback[snakeback.Count - 1]));

                Canvas.SetLeft(br, Canvas.GetLeft(snakeback[snakeback.Count - 1]));

                snakeback.Add(br);

            }

 

12.判断蛇与面板四周相撞或者蛇撞到自己，游戏结束。

 for (int i = 1; i < snake.Count; i++)

            {

                if (Canvas.GetTop(snake[0]) ==Canvas.GetTop(snake[i]) && Canvas.GetLeft(snake[0]) == Canvas.GetLeft(snake[i]))

                {

                    tm1.Stop();

                    MessageBox.Show("GAME  OVER!");

                }

            }

            if (Canvas.GetTop(snake[0]) == 0 ||Canvas.GetTop(snake[0]) == 560 || Canvas.GetLeft(snake[0]) == 0 || Canvas.GetLeft(snake[0]) == 790)

            {

                tm1.Stop();

                MessageBox.Show("GAME  OVER!");

            }
