Question

我正在Silverlight中开发简单的捕获应用程序（在Blend 4中）。你知道如何简单地解决掉落物体从顶部到底部的物体碰撞到白色矩形吗？图片 - http://img94.imageshack.us/img94/8200/svlk.jpg

当前代码：

public partial class MainPage : UserControl
{ 
    int skore=0;

    public MainPage()
    {
        InitializeComponent();
        chytac.Visibility=Visibility.Collapsed;
    }

    private void UserControl_KeyDown(object sender, System.Windows.Input.KeyEventArgs e)
    {
        String k=e.Key.ToString();
        klavesa.Content=k;
        if(e.Key.ToString().Equals("Left")){
            double x=Canvas.GetLeft(chytac);
            x=x-20;
            if(x>0){
                Canvas.SetLeft(chytac,x);
            }   

        }
        if(e.Key.ToString().Equals("Right")){
            double x=Canvas.GetLeft(chytac);
            x=x+20;
            if(x<650){
                Canvas.SetLeft(chytac,x);
            }   

        }
    }

    private void start_Click(object sender, System.Windows.RoutedEventArgs e)
    {
        chytac.Visibility=Visibility.Visible;
        start.Visibility=Visibility.Collapsed;
    }

    private void random_Click(object sender, System.Windows.RoutedEventArgs e)
    {
        Random random = new Random();
        //pocitadlo++;
        //score.Content=pocitadlo.ToString();
        telefon novy = new telefon();
        LayoutRoot.Children.Add(novy);
        Canvas.SetTop(novy, 0);
        Canvas.SetLeft(novy, random.Next(0,650));
        Canvas.SetZIndex(novy, -50);

        bomba bomba=new bomba();
        LayoutRoot.Children.Add(bomba);
        Canvas.SetTop(bomba, 0);
        Canvas.SetLeft(bomba, random.Next(0,650));
        Canvas.SetZIndex(bomba, -50);
    }
}

如果您可以将对象表示为矩形（或矩形集），则只需检查矩形是否与白色矩形重叠。复杂的形状可能需要更高级的算法。有许多精灵库可用，例如Silversprite
