Functions

  Type Name Description
Public function FKeyHandle

AddKey ( float InTime,
int32 InValue,
FKeyHandle KeyHandle
)

 Add a new key to the curve with the supplied Time and Value.
Public function void Removes the default value for this curve.
Public function void

DeleteKey ( FKeyHandle KeyHandle
)

 Remove the specified key from the curve.
Public function Const int32

Evaluate ( float Time,
int32 InDefaultValue
)

 Evaluates the value of an array of keys at a time
Public function Const FKeyHandle

FindKey ( float KeyTime,
float KeyTimeTolerance
)

  
Public function Const FKeyHandle

FindKeyBeforeOrAt ( float KeyTime
)

 Gets the handle for the last key which is at or before the time requested.
Public function Const int32 Get the default value for the curve
Public function FIntegralKey &

GetKey ( FKeyHandle KeyHandle
)

 Functions for getting keys based on handles
Public function Const FIntegralKey

GetKey ( FKeyHandle KeyHandle
)

 Functions for getting keys based on handles
Public function Const TArray< FIntegralKey >::TConstIterator Const iterator for the keys, so the indices and handles stay valid
Public function Const int32

GetKeyValue ( FKeyHandle KeyHandle
)

 Get the value for the Key with the specified index.
Public function Const bool Gets whether or not the default value should be used for evaluation for time values before the first key.
Public function Const bool Check whether this curve has any data or not
Public function void Tries to reduce the number of keys required for accurate evaluation (zero error threshold)
Public function void

SetDefaultValue ( int32 InDefaultValue
)

 Set the default value for the curve
Public function void

SetKeyValue ( FKeyHandle KeyHandle,
int32 NewValue
)

 Set the value of the key with the specified index.
Public function void

SetUseDefaultValueBeforeFirstKey ( bool InbUseDefaultValueBeforeFirstKey
)

 Sets whether or not the default value should be used for evaluation for time values before the first key.
Public function FKeyHandle

UpdateOrAddKey ( float InTime,
int32 Value,
float KeyTimeTolerance
)

 Finds the key at InTime, and updates its value.

Overridden from FIndexedCurve

  Type Name Description
