備註

時間軸代表時間區段。A timeline represents a segment of time. 它提供的屬性可讓您指定時間片段長度、應開始的時間、重複次數、時間在該片段中的播放速度等等。It provides properties that enable you to specify the length of that segment, when it should start, how many times it will repeat, how fast time progresses in that segment, and more.

從時間軸類別繼承的類別提供額外功能,例如,動畫和媒體播放。Classes that inherit from the timeline class provide additional functionality, such as animation and media playback. 以下是一些不同類型的特定可用時間軸範例。The following are examples of some of the different types of specialized timelines available.

  • 動畫:AnimationTimeline是產生輸出值的時間軸類型。Animations: An AnimationTimeline is a type of timeline that produces output values. 當您將動畫與屬性產生關聯時, 動畫會在其播放時更新屬性的值, 藉此以動畫顯示。When you associate an animation with a property, the animation updates the property's value as it plays, thereby "animating" it. 如需動畫的簡介, 請參閱動畫總覽For an introduction to animations, see Animation Overview. 如需套用動畫之不同方式的詳細資訊, 請參閱屬性動畫技術總覽For information about the different ways to apply animations, see the Property Animation Techniques Overview.

  • MediaTimelines:MediaTimeline是一種可控制媒體檔案播放的時間軸。MediaTimelines: A MediaTimeline is a type of timeline that controls the playback of a media file.

  • ParallelTimelines:ParallelTimeline是一種時間軸類型, 可將其他時程表分組。ParallelTimelines: A ParallelTimeline is a type of timeline that groups other timelines.

  • 分鏡腳本:是特殊類型的ParallelTimeline , 可為其包含的時間軸提供物件和屬性目標資訊。 StoryboardStoryboards: A Storyboard is a special type of ParallelTimeline that provides object and property targeting information for the timelines it contains. 如需Storyboard物件的詳細資訊, 請參閱分鏡腳本總覽For more information about Storyboard objects, see the Storyboards Overview.

如需使用時間軸的詳細資訊, 請參閱動畫總覽For more information about using timelines, see the Animation Overview. 如需時間軸計時功能的簡介, 請參閱計時行為總覽For an introduction to the timing features of timelines, see the Timing Behaviors Overview.

資料系結和動畫時間軸Data Binding and Animating Timelines

大部分的時間軸屬性可以是資料系結或動畫;不過, 由於計時系統的運作方式, 資料系結或動畫時間軸的行為不像其他資料系結或動畫物件。Most timeline properties can be data bound or animated; however, because of the way the timing system works, data bound or animated timelines do not behave like other data bound or animated objects. 若要瞭解其行為, 它有助於瞭解啟動時程表的意義。To understand their behavior, it helps to understand what it means to activate a timeline.

套用時間軸時, 會製作時程表和其子時間軸的複本。When a timeline is applied, copies are made of the timeline and its child timelines. 這些複本會凍結 (設為唯讀), 並Clock從它們建立物件。These copies are frozen (made read-only) and Clock objects are created from them. 這就是執行以動畫顯示目標屬性之實際工作的時鐘。It's these clocks that do the actual work of animating the targeted properties. 如果時間軸是資料系結或動畫, 則在建立時鐘時, 會建立其目前值的快照集。If a timeline was data bound or animated, a snapshot of its current values was made when its clock was created. 雖然原始時程表可能會繼續變更, 但其時鐘並不會。Even though the original timeline might continue to change, its clock does not.

若要讓時程表反映資料系結或動畫變更, 必須重新產生其時鐘。For a timeline to reflect data binding or animation changes, its clock must be regenerated. 時鐘不會自動產生。Clocks are not regenerated for you automatically. 以下是幾種可套用時間軸變更的方式︰The following are several ways to apply timeline changes:

  • 如果時間軸為或屬於, 您Storyboard可以BeginStoryboard使用或Begin方法來重新套用其分鏡腳本, 使其反映變更。If the timeline is or belongs to a Storyboard, you can make it reflect changes by reapplying its storyboard using a BeginStoryboard or the Begin method. 這也會一併重新啟動動畫。This has the side effect of also restarting the animation. 在程式碼中, 您可以Seek使用方法, 將分鏡腳本推進回到先前的位置。In code, you can use the Seek method to advance the storyboard back to its previous position.

  • 如果您使用BeginAnimation方法將動畫直接套用至屬性, 請再次BeginAnimation呼叫方法, 並將已修改的動畫傳遞給它。If you applied an animation directly to a property using the BeginAnimation method, call the BeginAnimation method again and pass it the animation that's been modified.

  • 如果您直接在時鐘層級運作,請建立並套用一組新的時鐘,並使用它們來取代前一組產生的時鐘。If you are working directly at the clock level, create and apply a new set of clocks and use them to replace the previous set of generated clocks.

如需資料系結動畫的範例, 請參閱主要曲線動畫範例For an example of a data bound animation, see the Key Spline Animation Sample .

使用時間表做為計時器Using a Timeline as a Timer

時間軸的時鐘只會在有相關聯的事件處理常式或與屬性相關聯的 (如果AnimationClock是物件) 時才會進行。A timeline's clock will only progress when there's an event handler associated with it or (in the case of an AnimationClock object) it is associated with a property. 基於這個理由 (和其他人), 不建議您使用Timeline做為計時器。For this reason (and others), it's not recommended that you use a Timeline as a timer.
