    I'm trying to force the folding of an object with children, in the Object Manager.
    I tried it in COFFEE and it didn't work.
    Now I was trying to do it in Python and it seems that it doesn't work either :-(
    I tried with:

    op.SetBit(BIT_OFOLD)

    and with

    op.SetBit(NBIT_OM1_FOLD)

    But nothing happens. Is it also not possible with Python?

    Have You tried 'GeListNode.ChangeNBit(c4d.NBIT_OM1_FOLD, c4d.NBITCONTROL_SET)' in Python?

    How should I apply it?
    Like this?

    op.ChangeNBit(c4d.NBIT_OM1_FOLD, c4d.NBITCONTROL_SET)

    If it is, it is still not working :-(

    It's necessary to inform the manager about the update with an EventAdd().

    Toggles the fold state:

      
op.ChangeNBit(c4d.NBIT_OM1_FOLD, c4d.NBITCONTROL_TOGGLE)  
op.Message(c4d.MSG_CHANGE)  
c4d.EventAdd()

    Well, what I'm trying to achieve is an object that folds itself as soon as an object is dropped in or outside it.
    For that, I created a Python Generator with the following code:

      
old_childs=0   
  
import c4d   
#Welcome to the world of Python   
  
def main() :   
    global old_childs   
    childs=0   
    current=op.GetDown()   
    if current is None: return   
       
    while current is not None:   
        childs=childs+1   
        current=current.GetNext()   
       
    if childs==old_childs: return   
    old_childs=childs   
    op.ChangeNBit(c4d.NBIT_OM1_FOLD, c4d.NBITCONTROL_SET)   
    op.Message(c4d.MSG_CHANGE)   
    c4d.EventAdd()   
    return c4d.BaseObject(c4d.Onull)

    But it is not working. Could it be because the object is trying to fold itself?

    A bit confusing, but the clear bit folds the object.

    Example for Python generator:

      
import c4d  
#Welcome to the world of Python  
  
  
def main() :  
  op.ChangeNBit(c4d.NBIT_OM1_FOLD, c4d.NBITCONTROL_CLEAR)  
  op.Message(c4d.MSG_CHANGE)  
  c4d.EventAdd()  
   
  return c4d.BaseObject(c4d.Ocube)  
 

    Personally I think it's not a good idea to do and I'm not sure if it's thread safe etc.

    cheers,
    Matthias

    Weird!! I would assume that to fold we would need to SET the bit.
    This is for a Vault object - I would place in it objects that I want to keep but that I currently don't need.
    It will only fold when objects are added or removed from it. But I can still fold/unfold it manually.
    Thank you very much for your help, Matthias.

    This should work in an Python Expression Tag.
    Let me know.
    Should you need to do this via a Command script,
    you would need to store the childcount in the parent object
    itself, using a unique ID from PlugIn Cafe'.

    Cheers

import c4d   
  
childcountmemo = 0   
  
def main() :   
    global childcountmemo   
    obj = op.GetObject()   
    obj[c4d.TPYTHON_RESET] = False # Turn off 'Reset on Frame 0'   
    obj[c4d.TPYTHON_FRAME] = False # and 'Frame Dependent'   
    childcount = len(obj.GetChildren())   
       
    if childcount != childcountmemo and obj.GetNBit(c4d.NBIT_OM1_FOLD) :   
        obj.ChangeNBit(c4d.NBIT_OM1_FOLD,c4d.NBITCONTROL_CLEAR)   
          
    childcountmemo = childcount
