CParabolicTransitionFromAcceleration Class

Encapsulates a parabolic-acceleration transition.

Syntax

class CParabolicTransitionFromAcceleration : public CBaseTransition;

Members

Public Constructors

Name	Description
CParabolicTransitionFromAcceleration::CParabolicTransitionFromAcceleration	Constructs a parabolic-acceleration transition and initializes it with specified parameters.

Public Methods

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

Public Data Members

Name	Description
CParabolicTransitionFromAcceleration::m_dblAcceleration	The acceleration of the animation variable during the transition.
CParabolicTransitionFromAcceleration::m_dblFinalValue	The value of the animation variable at the end of the transition.
CParabolicTransitionFromAcceleration::m_dblFinalVelocity	The velocity of the animation variable at the end of the transition.

Remarks

During a parabolic-acceleration transition, the value of the animation variable changes from the initial value to the final value ending at a specified velocity. You can control how quickly the variable reaches the final value by specifying the rate of acceleration. 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.

CParabolicTransitionFromAcceleration::CParabolicTransitionFromAcceleration

Constructs a parabolic-acceleration transition and initializes it with specified parameters.

CParabolicTransitionFromAcceleration(
    DOUBLE dblFinalValue,
    DOUBLE dblFinalVelocity,
    DOUBLE dblAcceleration);

Parameters

dblFinalValue
The value of the animation variable at the end of the transition.

dblFinalVelocity
The velocity of the animation variable at the end of the transition.

dblAcceleration
The acceleration of the animation variable during the transition.

CParabolicTransitionFromAcceleration::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.

CParabolicTransitionFromAcceleration::m_dblAcceleration

The acceleration of the animation variable during the transition.

DOUBLE m_dblAcceleration;

CParabolicTransitionFromAcceleration::m_dblFinalValue

The value of the animation variable at the end of the transition.

DOUBLE m_dblFinalValue;

CParabolicTransitionFromAcceleration::m_dblFinalVelocity

The velocity of the animation variable at the end of the transition.

DOUBLE m_dblFinalVelocity;
