    Hey all,

    I'm having a weird issue. I'm trying to make a custom selection in a specific order, but when using the call doc.SetActiveObject(o, c4d.SELECTION_ADD), it doesn't add properly..

    For an example, make 4 objects in your document named "1", "2", "3", and "4". Now run this script.

    def main() :
        
        for index, name in enumerate([2,1,4,3]) : # Random order for testing
            obj = doc.SearchObject(str(name))
            if index == 0:
                doc.SetActiveObject(obj, c4d.SELECTION_NEW) # new selection for the first object
                continue
            doc.SetActiveObject(obj, c4d.SELECTION_ADD)
            
        c4d.EventAdd()

    newSelection = doc.GetActiveObjects(c4d.GETACTIVEOBJECTFLAGS_SELECTIONORDER)
        print [o.GetName() for o in newSelection] # print new selection. It's wrong

    if __name__=='__main__':
        main()

    It's just a random order, and not the order I want. Any ideas?

    Hello,

    objects are typically selected in the Object Manager. The Object Manager does take care that certain internal caches are updated when the object selection is changed.

    You can force the update of these caches by calling GetActiveObject() while you change the selection:

      
for index, name in enumerate([4,1,3,2]) : # Random order for testing  
     obj = doc.SearchObject(str(name))  
       
      doc.GetActiveObject()     
        
      if index == 0:  
              doc.SetSelection(obj, c4d.SELECTION_NEW) # new selection for the first object  
              continue  
      doc.SetSelection(obj, c4d.SELECTION_ADD)

    Best wishes,
    Sebastian

    Hello

    I think the question is not completely answered -

    your code work but it will not hold the right order of the selection.

    this will select the objects from 1-4 but when you call - doc.GetActiveObjects(c4d.GETACTIVEOBJECTFLAGS_SELECTIONORDER) the order will not  be 1-4

    Add 4 Null Objects in a document and run

    import c4d
from c4d import gui
#Welcome to the world of Python
  
  
def main() :
    mylist = doc.GetObjects()
    i=0
    print "-save-"
    for node in mylist:
        print node.GetName()
        if i == 0:
            doc.SetActiveObject(node, mode=c4d.SELECTION_NEW)
        else:
            doc.SetActiveObject(node, mode=c4d.SELECTION_ADD)
        i +=1
    c4d.EventAdd()
    
    print "-get-"
    
    getlist = doc.GetActiveObjects(c4d.GETACTIVEOBJECTFLAGS_SELECTIONORDER)
    for node in getlist:
        print node.GetName()
  
if __name__=='__main__':
    main()

    result is 
    -save-
    4
    3
    2
    1
    -get-
    2
    4
    3
    1

    Hello,

    as I said and showed in my post above, you have to call GetActiveObject() inside your selection loop.

    Best wishes,
