示例

以下示例将 BounceEase 缓动函数应用于 DoubleAnimation 以创建弹跳效果。

<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();
}

注解

BounceEase 有两个控制属性 Bounciness 和 Bounces ，这两个属性会影响函数的行为。

ElasticEase 是类似的缓动函数，适用于动画中的物理模拟。 与 BounceEase 的区别在于 ElasticEase 可以超出 “从/到 ”范围。 概念化这两个缓动函数的另一种方法是 ElasticEase 是可用于对字符串的拔出进行动画处理，而 BounceEase 是可用于显示球对线条或平面的弹跳。

缓动函数可以应用于 From/To/By 动画的 EasingFunction 属性，或应用于用于关键帧动画缓动变体的关键帧类型的 EasingFunction 属性。 有关详细信息，请参阅 关键帧动画和缓动函数动画。
