This class represents an easing function that creates an animated bouncing effect.

Methods

Method	Description
IXRBounceEase::GetBounces	Retrieves the number of bounces.
IXRBounceEase::GetBounciness	Retrieves a value that specifies how elastic the bounce animation is.
IXRBounceEase::SetBounces	Sets the number of bounces.
IXRBounceEase::SetBounciness	Sets a value that specifies how elastic the bounce animation is. Low values of this property result in bounces with little loss of height between bounces (more bouncy) while high values result in dampened bounces (less bouncy). A value of 1 results in bounces that are almost the same height as the full animation.

Thread Safety

Members of this class are thread safe if you previously called IXRApplication::CreateHostFromXaml and supplied it with an XRWindowCreateParams structure that has AllowsMultipleThreadAccess set to true.

Remarks

You can control when the animation bounces by passing one of the XREasingMode enumerated values to the inherited IXREasingFunctionBase::SetEasingMode method. The following graph demonstrates the different values of the easing mode, where f(t) represents the animation progress and t represents time.

You can specify how many bounces occur using the IXRBounceEase::SetBounces method and specify how elastic the bounces are using the IXRBounceEase::SetBounciness method.

When you create a class instance, use an IXRBounceEasePtr smart pointer instead of a raw interface pointer. For more information, see XRPtr<Interface>.

You can apply this easing function to an animation in Microsoft Silverlight 3 XAML. For information about the differences between XAML in Silverlight for Windows Embedded and Silverlight 3, see Differences Between Microsoft Silverlight 3 and Silverlight for Windows Embedded. For more information about how to define this element in the source XAML for your application, see the BounceEase Class on MSDN.

There are several other easing functions besides IXRBounceEase, which you can explore using the following sample:
