贪吃蛇双人python 贪吃蛇双人对战代码

贪吃蛇总结：

1. 创建WPF应用程序

 

1. 添加Canvas标签。Name=back；

 

1. 添加loaded事件

 

1. 在loaded事件中创建两条蛇（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);
  for (int i = 0; i < 5; i++)
            {
                bd1 = new Border();
                bd1.Width = bd1.Height = 10;
                bd1.CornerRadius = new CornerRadius(5);
                if (i == 0)
                    bd1.Background = Brushes.Chocolate;
                else
                    bd1.Background = Brushes.DarkBlue;
                Canvas.SetTop(bd1, 400 + i * bd1.Height);
                Canvas.SetLeft(bd1, 400);
                back.Children.Add(bd1);
                snack1.Add(bd1);
 
                //创建蛇的位置border
                Border bdback1 = new Border();
                bdback1.Height = bdback1.Width = 10;
                Canvas.SetTop(bdback1, 400 + i * bd1.Height);
                Canvas.SetLeft(bdback1, 400);
                snakeback1.Add(bdback1);
            }

 

1. 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;

1. 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";
            }
 if (e.Key == Key.W && s1 != "s")
            {
                s1 = "w";
            }
            if (e.Key == Key.S && s1 != "w")
            {
                s1 = "s";
            }
            if (e.Key == Key.A && s1 != "d")
            {
                s1 = "a";
            }
            if (e.Key == Key.D && s1 != "a")
            {
                s1 = "d";
            }
 
7.在timer事件中实现两条蛇的移动（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）
 
         private void Dt_Tick(object sender, EventArgs e)
        {
            if (s == "up")
            {
                Canvas.SetTop(snack[0], Canvas.GetTop(snack[0]) - snack[0].Height);
                Run();
            }
            if (s == "down")
            {
                Canvas.SetTop(snack[0], Canvas.GetTop(snack[0]) + snack[0].Height);
                Run();
            }
            if (s == "left")
            {
                Canvas.SetLeft(snack[0], Canvas.GetLeft(snack[0]) - snack[0].Width);
                Run();
            }
            if (s == "right")
            {
                Canvas.SetLeft(snack[0], Canvas.GetLeft(snack[0]) + snack[0].Width);
                Run();
            }
            if (s1 == "w")
            {
                Canvas.SetTop(snack1[0], Canvas.GetTop(snack1[0]) - snack1[0].Height);
                Run1();
            }
            if (s1 == "s")
            {
                Canvas.SetTop(snack1[0], Canvas.GetTop(snack1[0]) + snack1[0].Height);
                Run1();
            }
            if (s1 == "a")
            {
                Canvas.SetLeft(snack1[0], Canvas.GetLeft(snack1[0]) - snack1[0].Width);
                Run1();
            }
            if (s1 == "d")
            {
                Canvas.SetLeft(snack1[0], Canvas.GetLeft(snack1[0]) + snack1[0].Width);
                Run1();
            }
            for (int i = 0; i < 30; i++)
            {
                if (Canvas.GetTop(snack1[0]) == Canvas.GetTop(foodback[i]) && Canvas.GetLeft(snack1[0]) == Canvas.GetLeft(foodback[i]))
                {
                    y++;
                    l1.Content = "小强蛇分数：" + y;
                    Canvas.SetTop(foodback[i], ra.Next(60) * 10);
                    Canvas.SetLeft(foodback[i], ra.Next(80) * 10);
 
                    //创建一个border添加到尾部
                    Border bdfood1 = new Border();
                    bdfood1.Width = bdfood1.Height = 10;
                    bdfood1.Background = Brushes.DarkBlue;
                    bdfood1.CornerRadius = new CornerRadius(5);
                    Canvas.SetTop(bdfood1, Canvas.GetTop(snack[snack.Count - 1]));
                    Canvas.SetLeft(bdfood1, Canvas.GetLeft(snack[snack.Count - 1]));
                    snack1.Add(bdfood1);
                    back.Children.Add(bdfood1);
 
                    //创建一个border，存放加到后面的蛇身的位置
                    Border br1 = new Border();
                    Canvas.SetTop(br1, Canvas.GetTop(bdfood1));
                    Canvas.SetLeft(br1, Canvas.GetLeft(bdfood1));
                    snakeback1.Add(br1);
                }
            }
            for (int i = 0; i < 30; i++)
            {
                if (Canvas.GetTop(snack[0]) == Canvas.GetTop(foodback[i]) && Canvas.GetLeft(snack[0]) == Canvas.GetLeft(foodback[i]))
                {
                    x++;
                    l.Content = "小黑蛇分数：" + x;
                    Canvas.SetTop(foodback[i], ra.Next(60) * 10);
                    Canvas.SetLeft(foodback[i], ra.Next(80) * 10);
 
                    //创建一个border添加到尾部
                    Border bdfood = new Border();
                    bdfood.Width = bdfood.Height = 10;
                    bdfood.Background = Brushes.Black;
                    bdfood.CornerRadius = new CornerRadius(5);
                    Canvas.SetTop(bdfood, Canvas.GetTop(snack[snack.Count - 1]));
                    Canvas.SetLeft(bdfood, Canvas.GetLeft(snack[snack.Count - 1]));
                    snack.Add(bdfood);
                    back.Children.Add(bdfood);
 
                    //创建一个border，存放加到后面的蛇身的位置
                    Border br = new Border();
                    Canvas.SetTop(br, Canvas.GetTop(bdfood));
                    Canvas.SetLeft(br, Canvas.GetLeft(bdfood));
                    snakeback.Add(br);
                }
            }
  private void Run()
        {
            for (int i = 1; i < snack.Count; i++)
            {
                Canvas.SetTop(snack[i], Canvas.GetTop(snakeback[i - 1]));
                Canvas.SetLeft(snack[i], Canvas.GetLeft(snakeback[i - 1]));
            }
            for (int i = 0; i < snack.Count; i++)
            {
                Canvas.SetTop(snakeback[i], Canvas.GetTop(snack[i]));
                Canvas.SetLeft(snakeback[i], Canvas.GetLeft(snack[i]));
            }
        }
        private void Run1()
        {
            for (int i = 1; i < snack1.Count; i++)
            {
                Canvas.SetTop(snack1[i], Canvas.GetTop(snakeback1[i - 1]));
                Canvas.SetLeft(snack1[i], Canvas.GetLeft(snakeback1[i - 1]));
            }
            for (int i = 0; i < snack1.Count; i++)
            {
                Canvas.SetTop(snakeback1[i], Canvas.GetTop(snack1[i]));
                Canvas.SetLeft(snakeback1[i], Canvas.GetLeft(snack1[i]));
            }
        }
1. 添加食物
 for (int i = 0; i < 30; i++)
            {
                //创建食物
                food = new Border();
                food.Width = food.Height = 10;
                //food.Background = Brushes.Yellow;
                //设置阴影
                //food.Effect = new System.Windows.Media.Effects.DropShadowEffect();
                //背景色渐变
                food.Background = new LinearGradientBrush(Colors.Red, Colors.Yellow, new Point(0, 0.1), new Point(0.8, 0.5));
 
                Canvas.SetTop(food, ra.Next(60) * 10);
                Canvas.SetLeft(food, ra.Next(80) * 10);
                food.CornerRadius = new CornerRadius(10);
                back.Children.Add(food);
                foodback.Add(food);
            }

1. 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);
}

1. 在与食物相撞时添加一节蛇尾
2. 添加一个border来作为蛇尾，添加到snake集合中
3. 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);
            }
 for (int i = 0; i < 30; i++)
            {
                if (Canvas.GetTop(snack1[0]) == Canvas.GetTop(foodback[i]) && Canvas.GetLeft(snack1[0]) == Canvas.GetLeft(foodback[i]))
                {
                    Canvas.SetTop(foodback[i], ra.Next(60) * 10);
                    Canvas.SetLeft(foodback[i], ra.Next(80) * 10);
 
                    //创建一个border添加到尾部
                    Border bdfood1 = new Border();
                    bdfood1.Width = bdfood1.Height = 10;
                    bdfood1.Background = Brushes.DarkBlue;
                    bdfood1.CornerRadius = new CornerRadius(5);
                    Canvas.SetTop(bdfood1, Canvas.GetTop(snack[snack.Count - 1]));
                    Canvas.SetLeft(bdfood1, Canvas.GetLeft(snack[snack.Count - 1]));
                    snack1.Add(bdfood1);
                    back.Children.Add(bdfood1);
 
                    //创建一个border，存放加到后面的蛇身的位置
                    Border br1 = new Border();
                    Canvas.SetTop(br1, Canvas.GetTop(bdfood1));
                    Canvas.SetLeft(br1, Canvas.GetLeft(bdfood1));
                    snakeback1.Add(br1);
                }
            }

12.判断蛇撞到自己，游戏结束。

 

  

for (int i = 1; i < snack.Count; i++)
            {
                if (Canvas.GetTop(snack[0]) == Canvas.GetTop(snack[i]) && Canvas.GetLeft(snack[0]) == Canvas.GetLeft(snack[i]))
                {
                    dt.Stop();
                    if (x > y)
                    {
                        MessageBox.Show("GAME  OVER!" + "\n" + "小黑蛇赢！");
                    }
                    else if (y > x)
                    {
                        MessageBox.Show("GAME  OVER!" + "\n" + "小强蛇赢！");
                    }
                    else
                        if (x == y)
                    {
                        MessageBox.Show("GAME  OVER!" + "\n" + "平局！");
                    }
 
                }
            }
   for (int i = 1; i < snack1.Count; i++)
            {
                if (Canvas.GetTop(snack1[0]) == Canvas.GetTop(snack1[i]) && Canvas.GetLeft(snack1[0]) == Canvas.GetLeft(snack1[i]))
                {
                    dt.Stop();
                    if (x > y)
                    {
                        MessageBox.Show("GAME  OVER!" + "\n" + "小黑蛇赢！");
                    }
                    else if (y > x)
                    {
                        MessageBox.Show("GAME  OVER!" + "\n" + "小强蛇赢！");
                    }
                    else
                        if (x == y)
                    {
                        MessageBox.Show("GAME  OVER!" + "\n" + "平局！");
                    }
                }
            }

13.蛇与面板四周相撞，游戏结束

if (Canvas.GetTop(snack[0]) == 0 || Canvas.GetLeft(snack[0]) == 0 || Canvas.GetTop(snack[0]) == 500 || Canvas.GetLeft(snack[0]) == 780)
            {
                dt.Stop();
                if (x > y)
                {
                    MessageBox.Show("GAME  OVER!" + "\n" + "小黑蛇赢！");
                }
                else if (y > x)
                {
                    MessageBox.Show("GAME  OVER!" + "\n" + "小强蛇赢！");
                }
                else
                    if (x == y)
                {
                    MessageBox.Show("GAME  OVER!" + "\n" + "平局！");
                }
            }
  if (Canvas.GetTop(snack1[0]) == 0 || Canvas.GetLeft(snack1[0]) == 0 || Canvas.GetTop(snack1[0]) == 560 || Canvas.GetLeft(snack1[0]) == 780)
            {
                dt.Stop();
                if (x > y)
                {
                    MessageBox.Show("GAME  OVER!" + "\n" + "小黑蛇赢！");
                }
                else if (y > x)
                {
                    MessageBox.Show("GAME  OVER!" + "\n" + "小强蛇赢！");
                }
                else
                    if (x == y)
                {
                    MessageBox.Show("GAME  OVER!" + "\n" + "平局！");
                }

14.蛇与对方相撞，游戏结束

for (int i = 1; i < snack.Count; i++)
            {
                for (int j = 0; j < snack1.Count; j++)
                {
                    if (Canvas.GetTop(snack[0]) == Canvas.GetTop(snack1[j]) && Canvas.GetLeft(snack[0]) == Canvas.GetLeft(snack1[j])|| Canvas.GetTop(snack1[0]) == Canvas.GetTop(snack[i]) && Canvas.GetLeft(snack1[0]) == Canvas.GetLeft(snack[i]))
                    {
                        dt.Stop();
                        if (x > y)
                        {
                            MessageBox.Show("GAME  OVER!" + "\n" + "小黑蛇赢！");
                        }
                        else if (y > x)
                        {
                            MessageBox.Show("GAME  OVER!" + "\n" + "小强蛇赢！");
                        }
                        else
                            if (x == y)
                        {
                            MessageBox.Show("GAME  OVER!" + "\n" + "平局！");
                        }
                    }
 
                }
            }

15.添加开始、暂停、退出、难度选择

<Button x:Name="start" Content="开始" Canvas.Left="31" Canvas.Top="-36" Width="75" />
        <Button x:Name="stop" Content="暂停" Canvas.Left="130" Canvas.Top="-36" Width="75"/>
        <ComboBox x:Name="nandu" Canvas.Left="221" Canvas.Top="-38" Width="108"  IsReadOnly="True"/>
        <Button x:Name="tuichu" Content="退出" Canvas.Left="439" Canvas.Top="-36" Width="75"/>
 //开始按钮设置
            start.Height = 20;
            start.Width = 50;
            start.Background = Brushes.OrangeRed;
            start.Margin = new Thickness(20, 0, 20, 20);
            start.Click += Start_Click;
            //暂停按钮设计
            stop.Height = 20;
            stop.Width = 50;
            stop.Background = Brushes.OrangeRed;
            stop.Margin = new Thickness(0, 0, 60, 20);
            stop.Click += Stop_Click;
            //退出按钮设置
            tuichu.Height = 20;
            tuichu.Width = 50;
            tuichu.Background = Brushes.OrangeRed;
            tuichu.Margin = new Thickness(0, 0, 60, 20);
            tuichu.Click += Tuichu_Click;
            nandu.SelectedIndex = 0;
            nandu.Items.Add("学霸模式");
            nandu.Items.Add("学渣模式");
            nandu.Items.Add("学习模式");
            nandu.Background = Brushes.Blue;
            nandu.Margin = new Thickness(0, 0, 20, 20)
        private void Tuichu_Click(object sender, RoutedEventArgs e)
        {
            this.Close();
        }
 
        private void Stop_Click(object sender, RoutedEventArgs e)
        {
            dt.Stop();
        }
 private void Start_Click(object sender, RoutedEventArgs e)
        {
            if (nandu.SelectedValue.ToString() == "学霸模式")
            {
                dt.Interval = TimeSpan.FromMilliseconds(50);
            }
 
            else if (nandu.SelectedValue.ToString() == "学渣模式")
            {
                dt.Interval = TimeSpan.FromMilliseconds(200);
            }
            else if (nandu.SelectedValue.ToString() == "学习模式")
            {
                dt.Interval = TimeSpan.FromMilliseconds(100);
            }
            nandu.IsEnabled = false; ;
            dt.Start();
        }

1. 添加背景音乐按钮控制播放

<MediaElement Name="audio"/>
        <Button Name="music" Content="点我有音乐哦" Canvas.Left="347" Canvas.Top="-36" >
            <Button.Triggers>
                <EventTrigger RoutedEvent="Button.Click">
                    <BeginStoryboard>
                        <Storyboard>
                            <MediaTimeline Source="7895.WAV" Storyboard.TargetName="audio" RepeatBehavior="Forever" />
                        </Storyboard>
                    </BeginStoryboard>
                </EventTrigger>
            </Button.Triggers>
        </Button>

1. 其中遇到的问题：

设置button时，键盘的控制蛇移动的上下左右键会控制ComboBox，蛇不能移动

解决：将Button和ComboBox放在windows上面，而不是Canvas上面，当开始按钮按下时，设置ComboBox为不可用。
