IMPORT_C	TAlfTimedPoint	(	TReal32	aX,
			TReal32	aY
		)

Constructor that sets default values.

Parameters

TReal32 aX
TReal32 aY

TAlfTimedPoint(TReal32, TReal32, TInt)

IMPORT_C	TAlfTimedPoint	(	TReal32	aXTarget,
			TReal32	aYTarget,
			TInt	aTransitionTime
		)

Constructor. Enables target value setting.

Parameters

Member Functions Documentation

IntTarget()

IMPORT_C TPoint

IntTarget

(

)

const

Returns the target value of the point rounded to nearest integer values. Note that the TAlfTimedPoint values are floating-point.

Target() For returning the floating-point values.

IntValueNow()

IMPORT_C TPoint

IntValueNow

(

)

const

Returns the current interpolatad value of the point rounded to nearest integer values. Note that the TAlfTimedPoint values are floating-point.

ValueNow() For returning the floating-point current value.

SetMappingFunctionIdentifier(TInt)

IMPORT_C void

SetMappingFunctionIdentifier

(

TInt

aIdentifier

)

Sets identifier of a mapping function that affects the timed value for both components of the point.

Parameters

TInt aIdentifier

Identifier of a function that will map the current value to required number space.

SetStyle(TAlfInterpolationStyle)

IMPORT_C void

SetStyle

(

TAlfInterpolationStyle

aStyle

)

Sets the interpolation style of both components of the point.

Parameters

TAlfInterpolationStyle aStyle

Timed value interpolation style.

SetTarget(const TAlfRealPoint &, TInt)

IMPORT_C void	SetTarget	(	const TAlfRealPoint &	aPoint,
			TInt	aTransitionTime = 0
		)

Sets the target for the timed point.

Parameters

const TAlfRealPoint & aPoint	Target point.
TInt aTransitionTime = 0	Duration for reaching the target.

SetTarget(TReal32, TInt)

IMPORT_C void	SetTarget	(	TReal32	aValue,
			TInt	aTransitionTime = 0
		)

Sets the target value of both components of the timed point.

Parameters

TReal32 aValue	New target value.
TInt aTransitionTime = 0	Duration for reaching the target.

SetTargetWithSpeed(const TAlfRealPoint &, TReal32)

IMPORT_C void	SetTargetWithSpeed	(	const TAlfRealPoint &	aPoint,
			TReal32	aUnitsPerSecond
		)

Sets the target value for the timed point, with a transition that is done using a specific speed.

Parameters

const TAlfRealPoint & aPoint	Target point.
TReal32 aUnitsPerSecond	Units per second during the transition.

SetTargetWithSpeed(TReal32, TReal32)

IMPORT_C void	SetTargetWithSpeed	(	TReal32	aValue,
			TReal32	aUnitsPerSecond
		)

Sets the target value of both components of the timed point.

Parameters

TReal32 aValue	New target value.
TReal32 aUnitsPerSecond	Speed of change.

Target()

TAlfRealPoint

Target

(

)

const [inline]

TimeToTargetinMilliSeconds()

TAlfRealPoint

TimeToTargetinMilliSeconds

(

)

const [inline]

Returns the transition time value of the point.

ValueNow()

TAlfRealPoint

ValueNow

(

)

const [inline]

Returns the current value of the point.
