障礙物構建（三區域，基於第九節修改）

// 區域 1

        rect = new Rectangle();
        rect.Fill = new SolidColorBrush(Colors.GreenYellow);
        rect.Opacity = 0.3;
        rect.Stroke = new SolidColorBrush(Colors.Gray);
        rect.Width = GridSize;
        rect.Height = GridSize;
        Carrier.Children.Add(rect);
        Canvas.SetLeft(rect, x * GridSize);
        Canvas.SetTop(rect, y * GridSize);
    }
