Properties

Name	Description

Count	Return the number of knots.
IsReadOnly	Returns true if this Spline is read-only, false if it is mutable.

Methods

Name	Description
Add(BezierKnot)	Adds a knot to the spline.
Add(BezierKnot, TangentMode)	Adds a knot to the spline.
Add(BezierKnot, TangentMode, float)	Adds a knot to the spline.
Clear()	Remove all knots from the spline.
Contains(BezierKnot)	Return true if a knot is present in the spline.
Copy(Spline)	Copy the values from `copyFrom` to this spline.
CopyTo(BezierKnot[], int)	Copies the contents of the knot list to an array starting at an index.
EnforceTangentModeNoNotify(int)	Ensure that a BezierKnot has the correct tangent and rotation values to match it's TangentMode and tension. This can be necessary if knot data is modified outside of the Spline class (ex, manually setting the Knots array without taking care to also set the tangent modes).
EnforceTangentModeNoNotify(SplineRange)	Ensure that a BezierKnot has the correct tangent and rotation values to match it's TangentMode and tension. This can be necessary if knot data is modified outside of the Spline class (ex, manually setting the Knots array without taking care to also set the tangent modes).
