情節提要C＃動畫

Question

好吧，我希望房屋圖像從-5°旋轉到5° ，我編寫了以下代碼

        Duration duration2 = new Duration(TimeSpan.FromSeconds(1));

        Storyboard sb2 = new Storyboard();
        sb2.Duration = duration2;

        DoubleAnimation da2 = new DoubleAnimation();
        da2.Duration = duration2;

        sb2.Children.Add(da2);

        RotateTransform rt2 = new RotateTransform();

        Storyboard.SetTarget(da2, rt2);
        Storyboard.SetTargetProperty(da2, new PropertyPath("Angle"));
        da2.From = 5;
        da2.To = -5;

        HouseImg.RenderTransform = rt2;
        HouseImg.RenderTransformOrigin = new Point(0.5, 0.5);

        sb2.RepeatBehavior = RepeatBehavior.Forever;
        sb2.Begin();

但是，當它結束時，它會迅速到達起點（ 5° ），而我想要的也是對其進行動畫處理。 總結一下：我想從5°到-5°以及從-5°到5°設置動畫。

Tnx :)

將AutoReverse屬性設置為true 。

sb2.AutoReverse = true;
