Functions

	Name	Description
FKeyHandle	AddKey ( float InTime, float InValue, const bool bUnwindRotation, FKeyHandle KeyHandle )	Add a new key to the curve with the supplied Time and Value. Returns the handle of the new key.
void	BakeCurve ( float SampleRate, float FirstKeyTime, float LastKeyTime )
void	BakeCurve ( float SampleRate )	Bake curve given the sample rate
void	ClearDefaultValue()	Removes the default value for this curve.
void	CycleTime ( float MinTime, float MaxTime, float& InTime, int& CycleCount )
void	DeleteKey ( FKeyHandle KeyHandle )	Remove the specified key from the curve.
float	Eval ( float InTime, float InDefaultValue )	Evaluate this curve at the specified time
FKeyHandle	FindKey ( float KeyTime, float KeyTimeTolerance )	Finds a key a the specified time
float	GetDefaultValue()	Get the default value for the curve
int32	GetKeyIndex ( float KeyTime, float KeyTimeTolerance )
ERichCurveIn...	GetKeyInterpMode ( FKeyHandle KeyHandle )
TPair< float...	GetKeyTimeValuePair ( FKeyHandle KeyHandle )	Returns a pair for the specified key
float	GetKeyValue ( FKeyHandle KeyHandle )	Returns the value of the specified key
void	GetTimeRange ( float& MinTime, float& MaxTime )	Get range of input time values.
void	GetValueRange ( float& MinValue, float& MaxValue )	Get range of output values.
bool	HasAnyData()	Check whether this curve has any data or not
bool	KeyExistsAtTime ( float KeyTime, float KeyTimeTolerance )	True if a key exists already, false otherwise
void	ReadjustTimeRange ( float NewMinTimeRange, float NewMaxTimeRange, bool bInsert, float OldStartTime, float OldEndTime )	Resize curve length to the [MinTimeRange, MaxTimeRange]
void	RemapTimeValue ( float& InTime, float& CycleValueOffset )	Remap InTime based on pre and post infinity extrapolation values
void	RemoveRedundantKeys ( float Tolerance )	Remove redundant keys, comparing against Tolerance
void	RemoveRedundantKeys ( float Tolerance, float FirstKeyTime, float LastKeyTime )
void	Reset()	Clear all keys.
void	SetDefaultValue ( float InDefaultValue )	Set the default value of the curve
void	SetKeyInterpMode ( FKeyHandle KeyHandle, ERichCurveInterpMode NewInterpMode )
void	SetKeyValue ( FKeyHandle KeyHandle, float NewValue, bool bAutoSetTangents )	Set the value of the specified key
FKeyHandle	UpdateOrAddKey ( float InTime, float InValue, const bool bUnwindRotation, float KeyTimeTolerance )	Finds the key at InTime, and updates its value.
