Overview

Creates an action, based on a cardinal sline path.

Note: CCPointArray stores a series of CGPoint objects encoded as NSValue in a NSMutableArray.

Creating a Spline Action

+ actionWithDuration:points:tension:

Creates a cardinal spline action, based on control points and tension. A tension of 0, will return a curve following the straight lines in the point array. Increase value of tension to smooth out the curve.

Parameters

duration

Action duration.
points

Points to use for spline.
tension
