CSinusoidalTransitionFromRange Class

Encapsulates a sinusoidal-range transition that has a given range of oscillation.

Syntax

class CSinusoidalTransitionFromRange : public CBaseTransition;

Public Constructors

Name	Description
CSinusoidalTransitionFromRange::CSinusoidalTransitionFromRange	Constructs a transition object.

Public Methods

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

Public Data Members

Name	Description
CSinusoidalTransitionFromRange::m_dblMaximumValue	The value of the animation variable at a peak of the sinusoidal wave.
CSinusoidalTransitionFromRange::m_dblMinimumValue	The value of the animation variable at a trough of the sinusoidal wave.
CSinusoidalTransitionFromRange::m_duration	The duration of the transition.
CSinusoidalTransitionFromRange::m_period	The period of oscillation of the sinusoidal wave in seconds.
CSinusoidalTransitionFromRange::m_slope	The slope at the start of the transition.

Remarks

The value of the animation variable fluctuates between the specified minimum and maximum values over the entire duration of a sinusoidal-range transition. The slope parameter is used to disambiguate between the two possible sine waves specified by the other parameters. 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.

CSinusoidalTransitionFromRange::Create

Calls the transition library to create encapsulated transition COM object.

virtual BOOL Create(
    IUIAnimationTransitionLibrary* pLibrary,
    IUIAnimationTransitionFactory* \*not used*\);

Parameters

pLibrary
A pointer to transition library, which is responsible for creation of standard transitions.

Return Value

TRUE if transition is created successfully; otherwise FALSE.

CSinusoidalTransitionFromRange::CSinusoidalTransitionFromRange

Constructs a transition object.
