Encapsulates a sinusoidal-velocity transition that has an amplitude that is determined by the initial velocity of the animation variable.

Name	Description
CSinusoidalTransitionFromVelocity::CSinusoidalTransitionFromVelocity	Constructs a transition object.

Public Methods

Name	Description
CSinusoidalTransitionFromVelocity::Create	Calls the transition library to create encapsulated transition COM object. (Overrides CBaseTransition::Create.)

Public Data Members

Name	Description
CSinusoidalTransitionFromVelocity::m_duration	The duration of the transition.
CSinusoidalTransitionFromVelocity::m_period	The period of oscillation of the sinusoidal wave in seconds.

Remarks

The value of the animation variable oscillates around the initial value over the entire duration of a sinusoidal-range transition. The amplitude of the oscillation is determined by the animation variable's velocity when the transition begins. Because all transitions are cleared automatically, it's recommended to allocated them using operator new. The encapsulated IUIAnimationTransition COM object is created by CAnimationController::AnimateGroup, until then it's NULL. Changing member variables after creation of this COM object has no effect.
