re order user data

Hi,

Perhaps I am looking at it the wrong way, as I am still coming to grips with how the userdata container works - but I'd like to reorder the userdata on a generator object without removing it and rebuilding it. I can see that GetUserDataContainer() returns a list of containers - that's great - but I can't see a way to pass a new reordered list back to the object's userdata (I can only set or add individual elements, and new items are always added to the end of the stack regardless of ID).

Any tips?

cheers,
Iain

the indices arent working that way you think they do. an example sorting ud by its type:

import c4d
  
ORDER = [ c4d.DTYPE_BOOL, 
          c4d.DTYPE_LONG, 
          c4d.DTYPE_REAL, 
          c4d.DTYPE_VECTOR, 
          c4d.DTYPE_STRING, 
          c4d.CUSTOMDATATYPE_SPLINE ]
  
def main() :
    if op:
        udata = op.GetUserDataContainer()
        nid   = udata[len(udata)-1][0][1].id
        
        # delete existing ud
        for i in xrange(len(udata) + 1) :
            op.RemoveUserData(i)
            
        # we walk over our stored ud looking into the descid . for other ordering types like the name
        # look into c4d.Description - the name would be data[c4d.DESC_NAME] for example.
        res = []
        for dtype in ORDER:
            for descid, data in udata:
                if descid[1].dtype == dtype:
                   nid += 1
                   descid[1].id = nid
                   res.append((descid, data))
        
        # write data back
        for descid, data in res:
            op.SetUserDataContainer(descid, data)
        c4d.EventAdd()
        
if __name__=='__main__':
    main()
