Thanks,
Hm.
I can use GetVirtualObjects() and I now get a visible object.
If I create a BaseObject like Ocube it is recognized by ie a Cloner.
How ever if a create a Osplineobject or SplineObject (and set
it's points where I want them) I also get a visible object, -but-
it is not seen as a spline by a Cloner or an AlignToSpline Tag.
It -is- recognized by a SweepNurb.
Running MakeEditable or CurrentStateToObject I do get the correct
spline in return.

ok, so looking at the Py_DoubleCircle example it does not
use GetVirtualObjects() but GetContour() instead.
And it is seen by Cloner etc.
But what is it in that example that makes that happen?

When I use my "functional" spline code I don't get any errors
but no spline is generated. Doing MakeEditable I get
a Null Object in return.

What is it in GetContour that is important?
My plugin is based on the Py example and all I do
is create a simple spline with no settings at all,
no Draw, Handles or anything.

Oh, the reason why I'm trying the Object Plugin way
is that the setup is running using the Python Generator Object
and it has the same issue that a returned spline is not seen
by Cloners, AlignToSpline etc.

is it?
put in PyGenerator and make editable

  
import c4d  
#Welcome to the world of Python  
  
def main() :  
  spl = c4d.SplineObject(2,0)  
  spl.SetPoint(0,c4d.Vector(0.0))  
  spl.SetPoint(1,c4d.Vector(0.0,1000.0,0.0,))  
  spl.Message(c4d.MSG_UPDATE)  
  return spl

Hi Ilya.
I need to have the PyGenerator seen as a spline by a Cloner etc.
-without- making it editable the same way as a cube generated
in the PyGenerator is seen by a Cloner.

The PyDoubleCircle example manage that and I can't figure out why.

In C++. We need to use the " virtual SplineObject* GetContour() " method. As part of the class.
If it's left out. The spline does not even draw.
This does not seem to be the case in python.

Per the C++ SDK. GetContour() is used for generating splines.
AFAIK. It's not needed to generate other types of objects.

This is just a wild guess.
But it looks like the way the python version is ported from C++ is allowing us to generate splines in python without using GetContour(). Which might be a bad practice.
My guess is that this is not the "proper" way to build a spline generator. And will cause things like the Align-to-Spline tag not to work with it.

This is just a wild guess based on my experience with it in C++.

Hello Lennart
I try to put spl-pygen object, clonner draw it normally, without returning of base object(make editable) as described.

At more complex code, pyGen was failed at drawing of object if it is in clonner/or mo-object.

Also try Nux95's DrawApi helpers, thanks a'lot to Niklas!
Niklas, can you make sample with DrawLines if it-s possible, i some ago apply at sample project...but lost it....

Maybe I need to be even more clear

Make a PyGenerator generating a spline.
ie return c4d.BaseObject(c4d.Osplinecircle)

Then put the PyGenerator in a Cloner as Object source
does not allow me to clone stuff on the PyGenerator
as the Cloner does not see the PyGenerator as a spline.

Put the PyDoubleCircle in the Cloner instead as Object source
and I can clone.

The issue really comes down to that I can't see what in
the PyDoubleCircle example that makes it work.
(Other than it's using GetContour() )

seems it's not possible, if only add optionally new functions as presenting of PyGen like splineObj...like checkbox with GetContour dependecy

Update. I've actually got it working (as a plugin), stripping down the
PyDoubleCircle example bit by bit..
I'll post the barebone working code this week with a new question
as it became a new issue how handle updating it.
My guess it's about GetCache(), Get/SetDirty(), all new
territory for me.

Thanks till later!

That's a good twist, adding the Cloner link via the script, nice.
Don't need to do the CSTO either really.

You're right! Thanks a'lot.

I played with M.Zabiegly's pointcloud's sample(big thanks to his xpresso tutorials), trying to get cache from procedural objects(Lennart, i make same 3d fashion sample as you did) and try to apply same CSTO.

For CSTO and additional py-snippets i want to say Thanks to Sebastien, Niklas, Scott...

Not really I'm afraid.
But I've come a long way linking Cloners, MoSplines etc
from within the plugin as per the example you show earlier.
This way basically any virtual object within the generator
can be picked.

Hi Jack. That's what I did. But the issue turned out to be the cache.
As it only refresh itself internally and not from changes of external input.
I started another thread about that but it's not totally solved other than the workarounds mentioned there (link from within the script/code)
