Question

我在工作中很无聊，所以我试着制作一个简单的飞船射击游戏。当我按空格时，一个矩形被解雇了＃34;在页面上，每隔一个矩形从上到下。

我希望能够检查这两个是否相交，但因为两者都采用不同的方法，如果它们相交需要定期检查，我不知道如何解决这个问题。

这是我的代码，直到现在：

if (e.Key == Key.Space)
    {
        Rectangle rect = new Rectangle()
        {
            Width = 10,
            Height = 30,
            Fill = Brushes.Green,
            Stroke = Brushes.Red,
            StrokeThickness = 2,
        };
        Maingrid.Children.Add(rect);
        double countMult = countMove * 20;

        rect.Margin = new Thickness(countMult + 15, 350, 0, 0);

        double b = rect.Margin.Top;
        while(b>= -600){
            await Task.Delay(50);
            rect.Margin = new Thickness(countMult+15, b - 40, 0, 0);
            b = b-40;
        }
        Maingrid.Children.Remove(rect); 

    }
}

private async void Mainframe_Loaded(object sender, RoutedEventArgs e)
{
}

public async void enemyMethod(int width, int height, int speed, int x)
{
    Rectangle enemy = new Rectangle()
    {
        Width = width,
        Height = height,
        Fill = Brushes.Green,
        Stroke = Brushes.Blue,
        StrokeThickness = 2,
    };
    Maingrid.Children.Add(enemy);

    enemy.Margin = new Thickness(x, -590, 0, 0);

    double b = enemy.Margin.Top;
    while (b >= -600)
    {
        await Task.Delay(50);
        enemy.Margin = new Thickness(x, b + speed, 0, 0);
        b = b + speed;
    }
    Maingrid.Children.Remove(enemy);    
}



private async void ButtonStart_Click(object sender, RoutedEventArgs e)
{
    ButtonStart.Visibility = Visibility.Hidden;
    Random rnd = new Random();
    await Task.Delay(50);
    while (true)
    {
        int random_x = rnd.Next(-550, 550);
        enemyMethod(50, 30, 5, random_x); //width, height, speed, x-position
        await Task.Delay(1000);
    }
}

我知道如何检查它们是否与代码相交，但问题在逻辑上是如何将它拉下来的。

以不同方法相交矩形
