This class represents an animation that animates the value of an IXRDependencyObject along a set of key frames over a specified duration.

Methods

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

IXRObjectAnimationUsingKeyFrames stores a collection of IXRObjectKeyFrame objects that together define the key frames for the animation. The IXRObjectAnimationUsingKeyFrames::GetKeyFrames method retrieves the collection of target values for the key-frame animation. Each IXRObjectKeyFrame defines a segment of the animation with its own target object instance and key time. When the animation runs, it progresses from one key value to the next at the specified times.

IXRObjectKeyFrame is an intermediate base class for IXRDiscreteObjectKeyFrame. The IXRObjectAnimationUsingKeyFrames object, which swaps object values according to a specified timeline, can be used only with discrete interpolation. Other kinds of interpolation are not available to apply to objects.

You can use the methods inherited from the base class IXRTimeline to define the timeline for this animation.

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

You can also define an object animation that uses key frame in Microsoft Silverlight 3 XAML. For information about the differences between XAML in XAML for Windows Embedded and Silverlight 3, see Differences Between Microsoft Silverlight 3 and XAML for Windows Embedded. For more information about how to define this element in the source XAML for your application, see the ObjectAnimationUsingKeyFrames Class on MSDN.
