Hi guys.

I am using MakeLinearSplineLinear() in PYTHON, but this function is only implemented since R13. What function should I look in R12?

What I need to make, is in INIT stage I need to set 2 points on spline. Ho should this be done in R12?

Thank you.

Hi Tomas,

you can use the SplineData.SetKnot() method.

Hi Tomas,

Yes, you should instead call SplineData.InsertKnots() and set the tension with SplineData.SetRound().

You're right, my fault.

Thanks guys:), InsertKnot() seems to be working.
But maybe I am missing something else?
I am getting four point on the spline now

self.sizeSpline = c4d.SplineData()
            self.sizeSpline.SetRound(0)
            self.sizeSpline.InsertKnot(0, 1)
            self.sizeSpline.InsertKnot(1, 0)

And it looks nothing as expected:)

Hi Tomas,

I'm sure you wanted to thank Yannick, he told you about the InsertKnot() method.

You probably need to remove the points that are there by default. Use the DeleteAllKnots()
method before inserting your knots.

yeap, sorry about that Yannick:)

WOW - I removed points and now it works. Wo-Hoooo. Thank you everybody.
In case someone will find this topic useful, here's a code

  
spline = c4d.SplineData()   
spline.DeleteKnot(0)     #Delete Knot 0   
spline.DeleteKnot(0)     #Delete Knot 1   
spline.InsertKnot(0, 1) #Set the first knot's position   
spline.InsertKnot(1, 0) #Set the second knot's position   
print "Point Count: ", spline.GetKnotCount()

Hi Tomas,

Instead of using DeleteKnot() two times, you can just use DeleteAllKnots () to flush all knots
from the SplineData (as I suggested above).

Strage, but I get error "AttributeError: 'c4d.SplineData' object has no attribute 'DeleteAllKnots'"
if I use this:

spline = c4d.SplineData()
spline.DeleteAllKnots()

Hi Tomas,

I just tested it in R12 and I get the same error. The R12 documentation must be wrong then.
Alternatively, you can use this function:

def flush_splinedata(spl) :
    count = spl.GetKnotCount()
    for i in xrange(count) :
        spl.DeleteKnot(0)

spl = c4d.SplineData()
flush_splinedata(spl)
