我認爲類可以簡化您很多時間，並且代碼變得更有條理。我正在創建一個類，以便用代碼爲對象設置動畫。我創建的類使您可以使用主要動畫。如果我想動畫基於該類的對象，我會做：無法在背後的代碼上同時動畫兩個動畫
// Instantiate an object from animatinos class
MyStoryboards.Animations a = new MyStoryboards.Animations(this);
// add animations to storybaord
a.addAnimation(brdBorder, MyStoryboards.Animations.animProperty.TranslateX, 150, TimeSpan.FromSeconds(4));
a.addAnimation(brdBorder, MyStoryboards.Animations.animProperty.Rotate, 150, TimeSpan.FromSeconds(4));
a.addAnimation(brdBorder, MyStoryboards.Animations.animProperty.Opacity, 0, TimeSpan.FromSeconds(4),1,TimeSpan.FromSeconds(1), a.getBackEase());
// start animations
a.beginAnimation();
// delete all animations
a.removeAllAnimations();
，我當我執行該對象旋轉，它的不透明度動畫播放至。但它的翻譯沒有動畫。如果我擺脫：
a.addAnimation(brdBorder, MyStoryboards.Animations.animProperty.Rotate, 150, TimeSpan.FromSeconds(4));
那麼對象brdBorder將轉化allong x軸和它的不透明度也會被動畫。我剛剛完成這個課程的學習，我似乎無法弄清楚什麼時候我能夠同時動畫幾個東西，什麼時候我也無法動畫。大多數情況下，我可以製作兩個或兩個以上的動畫。
讓我來提供這個類的代碼，我認爲通過一些修改它可以非常有幫助。它的功能在於可以爲多個屬性設置動畫效果，但它在功能上並非功能強大，有時候您可能想同時爲兩件事物製作動畫。無論如何是這裏的代碼：

我認爲這個類可以節省大量的時間，是非常有用的。試一試。或者，也許我必須在單獨的線程中運行這些方法，以便同時對幾件事物進行動畫處理？
