贪吃蛇大作战双人版加强版完整代码加详细步骤，不懂问博主 啦啦啦。
贪吃蛇总结：
- 创建WPF应用程序
- 添加Canvas标签。Name=back；
- 添加loaded事件
- 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);
}
- 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;
- 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]));
}
}
- 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);
}
- 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);
}
- 在与食物相撞时添加一节蛇尾
- 添加一个border来作为蛇尾，添加到snake集合中
- 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();
}
- 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>
- 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。
