Hi,

I'm testing the SplineHelper class functions. But for some reason GetSegmentCount() always returns the value of one. Even though my spline has multiple segments.
Any idea what I'm doing wrong here?:

  
import c4d  
from c4d import gui  
  
def main() :  
  
 sh = c4d.utils.SplineHelp()  
 sh.InitSpline(op, rail=None, target_rail=True, use_deformed_points=True, force_update=True, use_global_space=True)  
 segCount = sh.GetSegmentCount()#Counts the total number of segments  
 segLength = sh.GetSegmentLength(0)#Gets the length of the first segment   
 totalLenght = sh.GetSplineLength()#Gets the length of the entire spline  
    
 print segCount  
 print segLength  
 print totalLenght   
  
if __name__=='__main__':  
  main()

It returns '2' here which is the correct value.
This is the spline I've tested:

Doh!

I guess I got confused about how these classes decide what a "segment" is.
After looking through my Coffee notes. I realized that what I was trying to do required using the SplineLengthData class.
Not the SplineHelp class.

Like this:

  
import c4d  
from c4d import gui  
  
def main() :  
  length = c4d.utils.SplineLengthData(op[0])#Creates a new instance of the SplineLengthData class  
  length.Init(op,0)# Initializes the spline object(op) and the first spline segment  
  print(length.GetLength())# The Spline's Length  
  print(length.GetSegmentLength(0,1))#The first segment's length  
  length.Free()#free up the memory used by the new SplineClass instance  
  
if __name__=='__main__':  
  main()
