Hi to everyone,

I'm trying to write a simple script that converts ringselections in points by melting the selected points.
In order to get an automatism I only select the first point, and python get the next neighbors by calling SendModelingCommand(c4d.MCOMMAND_SELECTGROW...).

Works how suggested up to this point.

Now the problem: because I need to keep the sourcepoint of every new ringselection I've tried to deselect the first point so I can melt the remaining points.

But I can't get this working. Either the whole selection disappears or nothing happens.
I've tried to get the BaseSelection.DeselectFrom(x) function working for me, but no success.

Here the code I'm using:

> def meltNextRing(doc,scriptParent) :
>     source = scriptParent[c4d.ID_USERDATA,2]            #the object to work on
>     doc.SetSelection(source,c4d.SELECTION_NEW)
>
>     sourcePoint = source.GetPointS()                    #get first point
>
>     settings = c4d.BaseContainer()
>     v = utils.SendModelingCommand(c4d.MCOMMAND_SELECTGROW,[source],c4d.MODELINGCOMMANDMODE_POINTSELECTION,settings,doc)
>     scriptParent.Message(c4d.MSG_UPDATE)
>
>     newSelection = source.GetPointS()
>     newSelection.DeselectFrom(sourcePoint)

Any suggestions?

Best regards,

After searching a few days I've found the answer in a post of NiklasR.

Here a little code-snippet in order to complete this thread and give anybody reading this the answer:

  
import c4d  
from c4d import documents, BaseSelect  
  
  
def main() :  
  doc = documents.GetActiveDocument()  
  obj = doc.SearchObject("Landschaft")                     #find the object of interest  
  
  selection = obj.GetPointS()                              #read all selected points in a BaseSelect  
  selectedPoints = []                                      #create an empty array  
  
  for i in xrange(obj.GetPointCount()) :                    #iteration over every point in the object  
      if selection.IsSelected(i) :                          #check if the actual point is recorded as selected in the BaseSelect  
          selectedPoints.append(obj.GetPoint(i))           #if the point is selected store it in the array  
    
  print selectedPoints                                     #print all selected points to the console

cheers,
