RotationCurve
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.
Summary
Properties
Number of rotation keys in this curve.
Methods
Returns a copy of a key at a given index.
Returns the index of the last and first key of a period of time.
Returns a copy of all the keys in the rotation curve as a Luau array of RotationCurveKeys.
Samples the rotation curve at a given time and returns the corresponding rotation as a CFrame.
Adds the key passed as an argument to this curve. If a key at the same time is found, it will be replaced.
Removes a given number of keys starting from a given index.
Resets this curve's keys using the RotationCurveKey array passed as an argument.
Properties
Methods
GetKeyAtIndex
Returns a copy of a key at a given index.
Parameters
Returns
GetKeyIndicesAtTime
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).
Parameters
Returns
GetKeys
Returns a copy of all the keys in the rotation curve as a Luau array of RotationCurveKeys.
Returns
Array of RotationCurveKeys.
GetValueAtTime
Samples the rotation curve at a given time and returns the corresponding rotation as a CFrame. Empty rotation curves are evaluated as CFrame.identity.
Parameters
Time at which to sample the curve.
Returns
Value of the curve at the requested time.
InsertKey
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.
Parameters
RotationCurveKey to insert.
Returns
(see description) .
RemoveKeyAtIndex
Removes a given number (count) of keys starting from the startingIndex index and returns the number of keys that were removed.
Parameters
Starting index from which to remove keys.
Number of keys to remove.
Returns
Number of keys removed.
SetKeys
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.
Parameters
Array of RotationCurveKeys.
Returns
Number of keys inserted.
