This class defines an animation segment that uses discrete values to animate from the color value of the previous key frame to its own value in a sudden manner.

Syntax

class IXRDiscreteColorKeyFrame : public IXRColorKeyFrame

Methods

This class defines no new methods. Its methods are inherited from IXRColorKeyFrame.

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

This class animates a color value along a set of key frames using an IXRColorKeyFrameCollection that belongs to an IXRColorAnimationUsingKeyFrames object.

A key frame defines a segment of the IXRColorAnimationUsingKeyFrames object it belongs to. Each key frame has a target color value and a key-time. The key-time specifies the time at which the target value of the key frame is reached. A key frame animates from the target value of the previous key frame to its own target value. It starts when the previous key frame ends, and it ends when its own key-time is reached.

Discrete key frames like IXRDiscreteColorKeyFrame do not interpolate between values, instead jumping suddenly to the new target value when the key-time of the key frame is reached.

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