Functions

  Type Name Description
Public function Virtual Const FIndexedCurve * Allocates a duplicate of the curve
Protected function Const void Makes sure our handles are all valid and correct.
Protected function Const void

EnsureIndexHasAHandle ( int32 KeyIndex
)

  
Protected function Const const int32 *

FindIndex ( FKeyHandle KeyHandle
)

 Gets the index of a handle .
Public function Const FKeyHandle Gets the key handle for the first key in the curve
Protected function Const int32

GetIndex ( FKeyHandle KeyHandle
)

 Gets the index of a handle.
Public function Const int32

GetIndexSafe ( FKeyHandle KeyHandle
)

 Gets the index of a handle, checks if the key handle is valid first.
Protected function Const FKeyHandle

GetKeyHandle ( int32 KeyIndex
)

 Internal tool to get a handle from an index.
Public function Const TArray< FKeyHandle >::TConstIterator Const iterator for the handles.
Public function Virtual Const float

GetKeyTime ( FKeyHandle KeyHandle
)

 Get the time for the Key with the specified index.
Public function Const FKeyHandle Gets the key handle for the last key in the curve
Public function Const FKeyHandle

GetNextKey ( FKeyHandle KeyHandle
)

 Get the next key given the key handle
Public function Virtual Const int32 Get number of keys in curve.
Public function Const FKeyHandle

GetPreviousKey ( FKeyHandle KeyHandle
)

 Get the previous key given the key handle
Public function Const bool Checks to see if the key handle is valid for this curve.
Public function void

ScaleCurve ( float ScaleOrigin,
float ScaleFactor
)

 Scales all keys about an origin, preserving order
Public function void

ScaleCurve ( float ScaleOrigin,
float ScaleFactor,
const TSet< FKeyHandle >& KeyHandles
)

 Scales all keys about an origin, preserving order
Public function Virtual void

SetKeyTime ( FKeyHandle KeyHandle,
float NewTime
)

 Move a key to a new time. This may change the index of the key, so the new key index is returned.
Public function void

ShiftCurve ( float DeltaTime
)

 Shifts all keys forwards or backwards in time by an even amount, preserving order
Public function void

ShiftCurve ( float DeltaTime,
const TSet< FKeyHandle >& KeyHandles
)

 Shifts all keys forwards or backwards in time by an even amount, preserving order
