備註

AnimationTimeline是一Timeline種物件類型, 會根據其計時進度產生輸出值。An AnimationTimeline is a type of Timeline object that generates output values based on its timing progress. 所有的動畫類型都會AnimationTimeline繼承自。All animation types inherit from AnimationTimeline.

無法凍結的功能: 因為它繼承自Freezable類別AnimationTimeline , 所以類別會提供幾個特殊功能AnimationTimeline : 物件可以宣告為, 在多個物件之間共用, 使其成為唯讀以改善效能、複製並使其成為安全線程。Freezable Features: Because it inherits from the Freezable class, the AnimationTimeline class provides several special features: AnimationTimeline objects can be declared as , shared among multiple objects, made read-only to improve performance, cloned, and made thread-safe. 如需Freezable物件所提供之不同功能的詳細資訊, 請參閱可凍結物件的總覽For more information about the different features provided by Freezable objects, see the Freezable Objects Overview.

給繼承者的注意事項

若要建立自訂動畫, 請覆寫或執行下列成員:To create a custom animation, override or implement the following members:

  • CreateInstanceCore() - If your new class is concrete, you must override CreateInstanceCore() to return a new instance of your class.

  • GetCurrentValue(Object, Object, AnimationClock)-覆寫這個方法, 以傳回您的動畫目前的值。
  • GetCurrentValue(Object, Object, AnimationClock) - Override this method to return the current value of your animation.
  • 它接受三個參數: 預設的原始值、預設的目的地值和AnimationClockIt takes three parameters: a default origin value, a default destination value, and an AnimationClock. AnimationClock使用來取得動畫的目前時間或進度。Use the AnimationClock to obtain the current time or progress for the animation. 您可以選擇是否要使用預設的來源和目的值。You can choose whether to use the default origin and destination values.
  • IsDestinationDefault-覆寫這個屬性, 以指出您的動畫是否使用GetCurrentValue(Object, Object, AnimationClock)方法所指定的預設目的地值。
  • IsDestinationDefault - Override this property to indicate whether your animation uses the default destination value specified by the GetCurrentValue(Object, Object, AnimationClock) method.

  • TargetPropertyType-覆寫這個屬性, 以Type指出動畫所產生的輸出。
  • TargetPropertyType - Override this property to indicate the Type of output your animation produces.
  • 如果類別不使用相依性屬性來儲存其資料或需要在建立之後額外進行初始化,您可能需要覆寫其他方法。如需詳細資訊,請參閱 Freezable 物件概觀If the class does not use dependency properties to store its data or it requires extra initialization after creation, you might need to override additional methods; see the Freezable Objects Overview for more information.
