Name	Description
CSmoothStopTransition::CSmoothStopTransition	Constructs a smooth-stop transition and initializes its maximum duration and final value.

Public Methods

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

Public Data Members

Name	Description
CSmoothStopTransition::m_dblFinalValue	The value of the animation variable at the end of the transition.
CSmoothStopTransition::m_maximumDuration	The maximum duration of the transition.

Remarks

A smooth-stop transition slows down as it approaches a given final value, and reaches it with a velocity of zero. The duration of the transition is determined by the initial velocity, the difference between the initial and final values, and the specified maximum duration. If there is no solution consisting of a single parabolic arc, this method creates a cubic transition. 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.
