Hi connor,
Probably because the attribute is not a custom data type..? Have you tried using __getitem__() ?
print bc[rig]

i try :
for id_, bc in op.GetUserDataContainer() : rig = id_[id_.GetDepth() - 1].id #print bc.GetCustomDataType(rig) print bc.__getitem__(rig) print bc[rig] print "name:" print bc[c4d.DESC_NAME] print "unit:" print bc[c4d.DESC_UNIT]
ig get for both None
Name and Unit are correct
i try to grap user data to and merge it to a gui interface

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.-ScottA

hey thanks for the many replies - i try to use DESC_PARENTGROUP to create own groups in the userdata - without success - has one of you a idea or an example how create own userdata groups
Many Thanks

Yeah. I have an example of using UD groups.
This script creates a python tag on the selected object. And then adds a UD group to it. Then it adds a couple of things into that group.
import c4d def main() : obj = doc.GetActiveObject() pyTag = c4d.BaseTag(1022749) #Create a python tag to host the User Data #The top most parent group rootGroup = c4d.GetCustomDatatypeDefault(c4d.DTYPE_GROUP) rootGroup[c4d.DESC_NAME] = "Root" rootGroup[c4d.DESC_TITLEBAR] = False rootGroup[c4d.DESC_LAYOUTGROUP] = True rootGroup[c4d.DESC_COLUMNS] = 3 pyTag.AddUserData(rootGroup) #A group that's a child of the root group childGroup = c4d.GetCustomDatatypeDefault(c4d.DTYPE_GROUP) childGroup[c4d.DESC_NAME] = "childGroup" childGroup[c4d.DESC_TITLEBAR] = False childGroup[c4d.DESC_PARENTGROUP] = pyTag.GetUserDataContainer()[0][0] pyTag.AddUserData(childGroup) #A string type UD entry for this group childGrp_Item1 = c4d.GetCustomDatatypeDefault(c4d.DTYPE_STRING) childGrp_Item1[c4d.DESC_NAME] = "Item1" childGrp_Item1[c4d.DESC_PARENTGROUP] = pyTag.GetUserDataContainer()[1][0] pyTag[pyTag.AddUserData(childGrp_Item1)] ="Hello World" #A Real type UD entry for this group childGrp_Item2 = c4d.GetCustomDatatypeDefault(c4d.DTYPE_REAL) childGrp_Item2[c4d.DESC_NAME] = "Item2" childGrp_Item2[c4d.DESC_PARENTGROUP] = pyTag.GetUserDataContainer()[1][0] pyTag[pyTag.AddUserData(childGrp_Item2)] = 55.6 obj.InsertTag(pyTag) c4d.EventAdd() if __name__=='__main__': main()

thanks scottA , is it possible to get out of the default user data group to create tab-items
Thanks

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.-ScottA
