Cocos2D

Inheritance: System.Object

Methods

CCCardinalSplineAt(CCPoint, CCPoint, CCPoint, CCPoint, float, float)

Cocos2D.CCPoint CCCardinalSplineAt(CCPoint, CCPoint, CCPoint, CCPoint, float, float)(Cocos2D.CCPoint p0, Cocos2D.CCPoint p1, Cocos2D.CCPoint p2, Cocos2D.CCPoint p3, System.Single tension, System.Single t)

See http://en.wikipedia.org/wiki/Cubic_Hermite_spline#Cardinal_spline

Parameters:

p0 (Cocos2D.CCPoint) - Control point 1

p1 (Cocos2D.CCPoint) - Control point 2

p2 (Cocos2D.CCPoint) - Control point 3

p3 (Cocos2D.CCPoint) - Control point 4

tension (System.Single) - The parameter c is a tension parameter that must be in the interval (0,1). In some sense, this can be interpreted as the "length" of the tangent. c=1 will yield all zero tangents, and c=0 yields a Catmull�Rom spline.

t (System.Single) - Time along the spline

Returns:

Cocos2D.CCPoint - The point along the spline for the given time (t)
