Description

This class holds a sorted list of RotationCurveKeys that represent a sequence of rotations. The shape of the interpolation curve between two keys is determined by the RotationCurveKey.Interpolation type.

GetKeyAtIndex

Parameters (1)
indexint
Returns (1)
RotationCurveKey

Returns a copy of a key at a given index.

GetKeyIndicesAtTime

Parameters (1)
timefloat
Returns (1)
Array

The first item in the returned array is the index of the last key with time less than or equal to time (or the lesser of either 1 or the curve length if no key was found). The second item in the returned array is the index of the first key with time greater than or equal to time (or the curve length if no key was found satisfying the inequality).

GetKeys

Parameters (0)
No parameters.
Returns (1)
Array

Returns a copy of all the keys in the rotation curve as a Lua array of RotationCurveKeys.

GetValueAtTime

Parameters (1)
timefloat
Returns (1)
CoordinateFrame?

Samples the rotation curve at a given time and returns the corresponding rotation as a CFrame. Empty rotation curves are evaluated as CFrame.identity.

Thread safetyUnsafe

InsertKey

Parameters (1)
keyRotationCurveKey
Returns (1)
Array

Adds the key passed as an argument to this curve. If a key at the same time is found, it will be replaced. In the returned array, the first value is true if a key was added or false if a previous key was replaced; the second value is the index at which the marker was added.

Length

TypeDefault
int0

Number of rotation keys in this curve.

This property is not replicated. Its interface does not cross the network boundary.
This property is read-only. Its value can be read, but it cannot be modified.

RemoveKeyAtIndex

Parameters (2)Default
startingIndexint
countint1
Returns (1)
int

Removes a given number (count) of keys starting from the startingIndex index and returns the number of keys that were removed.

Thread safetyUnsafe

SetKeys

Parameters (1)
keysArray
Returns (1)
int

Resets this curve's keys using the RotationCurveKey array passed as an argument. Keys in the keys array are sorted in ascending time order before insertion, and keys at duplicated times are removed in a stable manner.

Returns the number of keys actually inserted. Keys previously stored in this curve are removed before the keys passed as arguments are added.
