Own defined userdata ID

    Hi everybody,

    I have just a quick question:
    Is it possible via python script, or directly in C4D, to create a user data with an own defined ID?
    Normally C4D automatically gives the ID's, but I whant to choose the ID myself!
    So how can I achieve this? python? coffee? c4d itself?

    Thank you once for the effort!

    greetings,
    Christopher

    PS.: Sorry for my bad english, I am still lerarning this language^^

    hi,

    thanks for the fast answer, but I already found this page. And with this documentation it is only possible to create new userdata with their type, name and container. But the ID will still be set automaticly!
    But I for example whant to create a userdata with the type "text" and the name "insert your name" with the ID 51.

    So how can I set an ID by myself?

    greetings,
    Christopher

    hey^^

    at first I whantet to thank you for your post and your reply.
    but I see that my language is tied really too short!

    so now here a little more detail for my problem:
    I found this function

    Originally posted by xxxxxxxx

    called SetUserDataContainer().

    two days ago in the python sdk, downloadable at the maxon website.

    Because I am new to python, I tried this little skript:

    bc = c4d.GetCustomDatatypeDefault(c4d.DTYPE_LONG)
      bc[c4d.DESC_NAME] = "Test"
      print c4d.DTYPE_SUBCONTAINER
      newId = c4d.DescID(c4d.DescLevel(100, c4d.DTYPE_SUBCONTAINER, 0),c4d.DescLevel(0))
      print newId
      print type(newId)
      obj.SetUserDataContainer(newId, bc)
      c4d.EventAdd()

    But I can't figure out, what my mistake is!
    the documentary is very short and so I can't read something about it! I am really sorry for stealing your time with this "simple problem" like it is one for you, I guess!

    greetings,
    Christopher

    .. so why didn't you tell us earlier that you did already have a try? And what is your actual problem? I'm not at home, so
    without a description of why the code you have shown does not work, I can only guess or not give you a direct answer.

    yea, you are right about that. And I am really sorry about my inefficient question. I was very stressed the last few days and was not capable of finding the time for a good
    problem description.

    But I really thank you guys for helping me. Now it is working really fine and I had also the time to read throw the documentation. And with the code, littledevil posted, it was really easy to understand how the container works.

    Only one last thing is not clear to me, also after the things I learned!
    Creating a container for one userdata is clear to me now.
    Also how to create a userdata group:

    bc = c4d.GetCustomDatatypeDefault(c4d.DTYPE_GROUP)
    

    but how can I now put some userdata into this gorup, and some not?
    I can only put all in that one group, or none.
    But sometimes I have 3 different groups and maybe one of them also has a sub group.

    So would you be so nice and post a little "mini" skript in order to show me how to do that with an example?
    That would be really nice of you!

    greetings,
    Christopher

    PS.: Sorry again for last time and thanks again!

    ah, never mind, I searched in the posts of "littledevil" and found an old one where he listed all functions with there meaning.
    So I hope, I can solve the problem myself. I am not quite sure, but I will try my best ;)
    thank you again for all your help and maybe 'til the future^^

    greetings,
    Christopher
