範例

以下範例將 BounceEase 的緩和函數應用於 DoubleAnimation 以創造彈跳效果。

<StackPanel x:Name="LayoutRoot" >
    <StackPanel.Resources>
        <Storyboard x:Name="myStoryboard">
            <DoubleAnimation From="1" To="6" Duration="00:00:3" 
                Storyboard.TargetName="rectScaleTransform" 
                Storyboard.TargetProperty="ScaleY">
                <DoubleAnimation.EasingFunction>
                    <BounceEase Bounces="2" EasingMode="EaseOut" 
                                Bounciness="2" />
                </DoubleAnimation.EasingFunction>
            </DoubleAnimation>
        </Storyboard>
    </StackPanel.Resources>

    <Rectangle PointerPressed="Pointer_Clicked" 
     Fill="Blue" Width="200" Height="30">
        <Rectangle.RenderTransform>
            <ScaleTransform x:Name="rectScaleTransform" />
        </Rectangle.RenderTransform>
    </Rectangle>

</StackPanel>

// When the user clicks the rectangle, the animation
// begins. 
private void Pointer_Clicked(object sender, PointerRoutedEventArgs e)
{
    myStoryboard.Begin();
}

備註

BounceEase 有兩個控制特性：彈性與反彈，影響函數的行為。

ElasticEase 是一個類似的鬆動函式，非常適合動畫中的物理模擬。 和 BounceEase 的差別在於 ElasticEase 可以超出 From/To 範圍。 另一種概念化這兩個鬆動函數的方式是， ElasticEase 是用來動畫撥弦的動作，而 BounceEase 則是用來顯示球在線條或平面上的彈跳。

易解函數可以套用到FromTo/By動畫的/EasingFunction屬性，或用於關鍵影格動畫Ease變體的關鍵影格類型的EasingFunction屬性。 更多資訊請參見 關鍵影格動畫與輕鬆功能動畫。
