access userdata inside userdata group [SOLVED]

Hi, I am trying to create a script that will reset all the userdata under a userdata group back to their defaults. I am a Python beginner. Any suggestions as to how I would go about this? Any help would be greatly appreciated. Thanks.

So far I have this:

import c4d
for id, bc in op.GetUserDataContainer() :
    try:
        op[id] = bc[c4d.DESC_DEFAULT]
    except TypeError:
         #No or invalid default value.
        pass

c4d.EventAdd()

But this resets all the userdata and I want to reset only the userdata within a specific userdata group.

Hello,

if you just want to reset the userdata of a specific userdata group you have to check if a given userdata parameter is part of that group. You can access DESC_PARENTGROUP to get the ID of the parent group. So your code could look something like this:

  
  for id, bc in op.GetUserDataContainer() :  
  
      if bc[c4d.DESC_PARENTGROUP][-1].id == 2:  
          op[id] = bc[c4d.DESC_DEFAULT]  

Best wishes,
Sebastian

Hi
I test code and simple print to dive in to level

    for id, bc in op.GetUserDataContainer() :  
      print bc[c4d.DESC_PARENTGROUP][-1].id  
      if bc[c4d.DESC_PARENTGROUP][-1].id == 700:  
          op[id] = bc[c4d.DESC_DEFAULT]

i have id in level = 700.

Try such, code works for me

I tried your code and still get the same error message.

If I try this code from the Script Manager, it works and only userdata from group 255 is reset but when it is on a Python tag, it doesn't. Any suggestions?

import c4d

for id, bc in op.GetUserDataContainer() :
    
    if bc[c4d.DESC_PARENTGROUP][-1].id == 255:
        try:
            op[id] = bc[c4d.DESC_DEFAULT]
        except TypeError:

            pass

c4d.EventAdd()

For a Python Tag, "op" is the Tag, not the Object. Use the variable "obj" in all places instead of "op" and add "obj = op.GetObject()" beforehand.

Thanks, Niklas, that totally worked! The last thing I need and can't get to work is the switch. Here is what I have:

import c4d

obj = op.GetObject()
ID_RESET_Iceland = 39
        
def main() :
    
    for id, bc in obj.GetUserDataContainer() :
        
        if bc[c4d.DESC_PARENTGROUP][-1].id == 255:
            
            if obj[c4d.ID_USERDATA, ID_RESET_Iceland]:
                obj[c4d.ID_USERDATA, ID_RESET_Iceland] = False
                
                try:
                    obj[id] = bc[c4d.DESC_DEFAULT]
                except TypeError:
                     #No or invalid default value.
                    pass
    
    c4d.EventAdd()

Try this instead

ID_RESET_Iceland = 39
        
def main() :
    obj = op.GetObject()
    if not obj[c4d.ID_USERDATA, ID_RESET_Iceland]:
        return

Don't use that __name__ == "__main__" part in a Python Tag

It works! You are a genius! Thanks very much for this Niklas. 🙂

One problem, the script keeps looping after I activate the reset button. Is there a way to stop it?

Figured that out. Moved c4d.EventAdd() out of the for loop. But now it resets regardless of whether or not the reset switch is activated.

ID_RESET_Iceland = 39

    obj = op.GetObject()
