    I try to set User Data by python

    longUD = c4d.GetCustomDataTypeDefault(c4d.DTYPE_LONG)
        longUD[c4d.DESC_NAME] = "Long"
        add13 = obj.AddUserData(longUD)

    is it possible to set the type of long or the min and max values ?

    and is it possible to get this values by code ?

    thanks

    hey ferdinand,

    thanks for that - it was really helpful

    now I stuck on the problem to get the value back - i like to readout the userdata and translate them for a gui - i get all max and min and name but how can I get the Value so I need the ID -

    hope you understand my problem and may can help me - thanks

    for id, bc in op.GetUserDataContainer() :

    you are using GetUserDataContainer wrong. It returns a list of the user data
    containers and obviously not a specific container as you do not pass an id.
    so it returns a list of BaseContainer for which each stands for a user data
    element.

    for id, bc in op.GetUserDataContainer() :
        if isinstance(bc, c4d.BaseContainer) :
            for id, data in bc:
                print id, data

    Just as a side-note: GetUserDataContainer() garuantees to return a list of (DescID, BaseContainer),
    so you don't need the isinstance(bc, c4d.BaseContainer) part. :) Instead, you might want to check
    for a specific user-data ID.

    for id_, bc in op.GetUserDataContainer() :
        rid = id_[id_.GetDepth() - 1].id
        if rid == SOME_USERDATA_ID:
            print bc[c4d.DESC_NAME]

    Niklas and Ferdinand,

    thanks for the detailed replies, 
    Im a bit confused - the Id i get back is a Integer - but with that i dont get any data or value

    Hi connor,

    Probably because the attribute is not a custom data type..? Have you tried using __getitem__() ?

    Lol, sorry I messed up that bc is the item description container, not the host's container.
    So, what are you actually trying to do? Do you want to obtainthe parameter-name, min/max, etc. or
    do you want to get the actual parameters value?

    for id_, bc in op.GetUserDataContainer() :
        print bc[c4d.DESC_NAME]
        print op[id_] # Same as     op[c4d.ID_USERDATA, id_[id_.GetDepth() - 1]]

    hey niklas,

    both of them i need actual values and mast of the descriptions like max or min to rebuild the interface in a gui

    you are aware that there are no dynamic descriptions in python and rebuilding a userdata
    description container with a dialog resource can also become quite tricky, as dialog resources
    and descriptions are not the same, although both are resource based.

    First the solution to your request.
    Here is some code that will change the Min attribute on a Real type UD entry:

    import c4d  
    def main() :  
        
      obj = doc.GetFirstObject()      #The object hosting the UD    
      ud = obj.GetUserDataContainer() #The master UD container  
        
      for i, bc in ud:  
          level = i[1].id             #Get the ID# for each UD entry  
            
          if level == 1:              #If we find the first UD entry  
              bc[5]=  0.2             #Set the Min value to 20% in memory only!!!  
              obj.SetUserDataContainer(i, bc) #Set the container changes from memory  
        
      c4d.EventAdd()  
         
    if __name__=='__main__':  
      main()
    

    How did I come up with this code?
    I had to learn about how the UD system works. It's a rather convoluted system of a master base container. With sub containers. Which hold values consisting of Reals, Longs, Vectors, and Tuples.
    Then I mapped it out and made a note for myself to use as a reference guide on how to get at a specific UD attribute.

    This is one of several notes I've written to myself about How the UD system works.
    And how to get at the specific built-in attributes inside of them:

    #This is how to get at the options in a specific UD entry  
    #The options are different depending on what kind of UD item it is  
    #These options are descriptions found under "cid DESC_Items" in the sdk (lib_description.h)  
      
    import c4d  
    def main() :  
        
      obj = doc.GetFirstObject()      #The object hosting the UD    
      ud = obj.GetUserDataContainer() #The master UD container  
        
      first = ud[0]                   #The first UD entry (by it's stack position...not it's ID#)  
      
      #first is now a variable that holds a tuple of two base containers  
      #first[0] holds the level ID#, and two DescLevel objects  
      #first[1] holds the various options for the UD entry. Changed by accessing their descriptions  
      
      #Here is an example of accessing those options:  
      
      container = first[1]            #The second tuple container of the UD entry. Which holds most of the attributes  
        
      for i in container:  
          print i                     #Prints the container ID#s, values  
      
      
      #Examples of what some of these options are for the default UD type entry:  
      
      level    = first[0][1].id          #The level ID#  
      Lname    = first[1][1]             #The long name  
      Sname    = first[1][2]             #The short name  
      three    = first[1][3]             # 3 for certain UD types  
      minValue = first[1][5]             #Min value  
      maxValue = first[1][6]             #Max value   
      step     = first[1][9]             #Step Value  
      anim     = first[1][10]            #Animatable option  
      meters   = first[1][12]            #units type  
      tupleData =first[1][13]            # (700, 5, 0)  
      interface =first[1][21]            #interface type (float=19,  
                                                      #float slider=1000489,  
                                                      #float slider noedit = 200000006,  
                                                      #lat/lon = 1011148)  
      
      minslider =first[1][27]            #The min slider value (if enabled)  
      
    if __name__=='__main__':  
      main()
    

    I hope that help demystify UD a little bit.
    IMHO. The UD system is rather convoluted. Which I why I wrote myself lots of helper notes & guides like this one about it.

    You lost me on that one.
    UserData is created inside the UserData tab.

    If you're you asking me if we can create more than one User Data tab. And name them with our own custom names. My answer is I don't know. I've never tried it.
    But that's a good question.
