Functions

	Name	Description
FKeyHandle	AddKey ( float InTime, int32 InValue, FKeyHandle KeyHandle )	Add a new key to the curve with the supplied Time and Value.
void	ClearDefaultValue()	Removes the default value for this curve.
void	DeleteKey ( FKeyHandle KeyHandle )	Remove the specified key from the curve.
int32	Evaluate ( float Time, int32 InDefaultValue )	Evaluates the value of an array of keys at a time
FKeyHandle	FindKey ( float KeyTime, float KeyTimeTolerance )
FKeyHandle	FindKeyBeforeOrAt ( float KeyTime )	Gets the handle for the last key which is at or before the time requested.
int32	GetDefaultValue()	Get the default value for the curve
FIntegralKey...	GetKey ( FKeyHandle KeyHandle )	Functions for getting keys based on handles
FIntegralKey	GetKey ( FKeyHandle KeyHandle )	Functions for getting keys based on handles
TArray< FInt...	GetKeyIterator()	Const iterator for the keys, so the indices and handles stay valid
int32	GetKeyValue ( FKeyHandle KeyHandle )	Get the value for the Key with the specified index.
bool	GetUseDefaultValueBeforeFirstKey()	Gets whether or not the default value should be used for evaluation for time values before the first key.
bool	HasAnyData()	Check whether this curve has any data or not
void	RemoveRedundantKeys()	Tries to reduce the number of keys required for accurate evaluation (zero error threshold)
void	SetDefaultValue ( int32 InDefaultValue )	Set the default value for the curve
void	SetKeyValue ( FKeyHandle KeyHandle, int32 NewValue )	Set the value of the key with the specified index.
void	SetUseDefaultValueBeforeFirstKey ( bool InbUseDefaultValueBeforeFirstK... )	Sets whether or not the default value should be used for evaluation for time values before the first key.
FKeyHandle	UpdateOrAddKey ( float InTime, int32 Value, float KeyTimeTolerance )	Finds the key at InTime, and updates its value.

Overridden from FIndexedCurve

	Name	Description
FIndexedCurv...	Duplicate()	Allocates a duplicate of the curve
float	GetKeyTime ( FKeyHandle KeyHandle )	Get the time for the Key with the specified index.
int32	GetNumKeys()	Get number of keys in curve.
void	SetKeyTime ( FKeyHandle KeyHandle, float NewTime )	Move a key to a new time.
