Functions

RotationCurveKey

GetKeyAtIndex ( int index )

Returns a copy of a key at a given index.
Array

GetKeyIndicesAtTime ( float time )

Returns the index of the last and first key of a period of time.
Array

GetKeys ( )

Returns a copy of all the keys in the RotationCurve as a Lua array of RotationCurveKey.
CoordinateFrame

GetValueAtTime ( float time )

Samples the RotationCurve at a given time and returns the corresponding rotation. Empty RotationCurves are interpreted as zero.
Array

InsertKey ( RotationCurveKey key )

Adds the key passed as argument to this curve. If a key at the same time is found it will be replaced.
int

RemoveKeyAtIndex ( int startingIndex , int count )

Removes a given number of Keys starting from a given index. Returns the number of keys that were removed.
int

SetKeys ( Array keys )

Resets this curve keys using the RotationCurveKey array passed as argument.
