@i_mazlov This is very useful as it helps avoid manually inputting hard-coded index values! Thank you, and have a great day!

Hello all, I need to dynamically obtain the number of Targets in a Constraint tag. I couldn't find a 'Constraint tag' class, and the BaseTag class offers very limited functionality. I had to try retrieving the information from the container. Fortunately, the container contains the data I need. However, I'm curious if there's a more elegant solution beyond using the container?

import c4d

def getTargetCount(tag) -> int:
   tagData    = tag.GetDataInstance()
   count      = 0
   startIndex = 10002

   while True:
       if tagData.GetData(startIndex) is None:
           break
       count      += 1
       startIndex += 10

   return count

def main():
   tag = doc.GetSelection()[0]
   print(getTargetCount(tag))
   

if __name__ == '__main__':
   main()

@i_mazlov Thank you

Hello all, I would like to know if C4D can hide an object's native attributes (e.g., hiding the Object tab of a spline object). This would help avoid unnecessary attributes when selecting the corresponding controllers while animating, thus improving efficiency. In the following code, I found that SetParameter doesn't work. I can only hide custom user data attributes

import c4d

def main():
   obj = op
   description = obj.GetDescription(c4d.DESCFLAGS_DESC_NONE)
   doc.StartUndo()

   for bc, paramId, groupId in description:

       if bc[c4d.DESC_NAME] == 'Object Properties':
           doc.AddUndo(c4d.UNDOTYPE_CHANGE, obj)
           print(bc[c4d.DESC_HIDE])                    #  return None
           bc[c4d.DESC_HIDE] = False

           obj.SetParameter(groupId, bc, c4d.DESCFLAGS_SET_NONE)
         # obj.SetUserDataContainer(groupId, bc)      # hide userData attr
           obj.Message(c4d.MSG_CHANGE)

   doc.EndUndo()
   c4d.EventAdd()

if __name__ == '__main__':
   main()
