有一些真正的頭部劃傷在這裏,因爲我似乎無法想象爲什麼我得到的動畫目標沒有指定的錯誤。我創建了一個靜態類,用於展示出許多小火災「刻錄」的故事板。然後,我會根據用戶的需求創建儘可能多的火災,併爲其分配一個新的故事板,全部在Csharp中。然後,我開始故事板,但正如我所說,我不斷收到這個錯誤,我不明白爲什麼。這是故事板創建類,當我嘗試調用它時。動畫目標未指定問題 - Silverlight故事板

而且這裏是我把它分配給每個火圖像:

fireStoryboard.Begin();
任何幫助將不勝感激。我是否錯過在某處設置目標?我真的不知道在哪裏:(。
我現在得到一個新的錯誤,指出「無法解析指定對象上的TargetProperty(UIElement.RenderTransform)。(CompositeTransform.ScaleY)」。我認爲scaleY將可能與圖像? – Christian
