Hi there. That's my first post here:)
Feeling kinda newbee :)))

Any ways, I have a little question. in COFFEE I am trying to use CallCommand(1019951); // Delete Without Children command. Unfortunatly, I cannot find a way to add Undo step to it. Here's a code:

	var deleteme = doc->GetActiveObject();
	deleteme->SetBit(BIT_ACTIVE);
	doc->AddUndo(UNDO_DELETE, deleteme);

	CallCommand(1019951); // Delete Without Children

:((((
Any help to solve this would be sweet:)
Thanks in advance.

Tomas Sinkunas.

CallCommand(...) automatically adds an undo step.

well, in my case it just don't work:)

every step, until this command is called, works with UNDO. But when I add this call command function, I need to press 2 times UNDO button to come back to original state:(

As I said CallCommand() adds automatically an undo step. You can't collect CallCommand() undo steps to undo them all in one go.

I see:( That's sad:(

But maybe there's a different way to make the same action as this CallCommand(1019951); // Delete Without Children does? I mean instead of calling command, I could code some lines to perform this particular action?

Yes, you can. Do the according actions yourself. Copy Children -> Delete Original hierarchy -> ReInsert copied children-> Add Undo.

You find all necessary information on the operations here in the forum and in the docs.

this method you described sounds good, but unfortunately I have no clue how to COPY object:(( For deleting and inserting, I think I can handle, but COPYING - please help.

Please, guys, help.

I have a null object as a parent and a cube as a child of that null. Null object has one position coordinates, cube has different coordinates. I need to move that cube out of that null object but still stay at same position. I mean cubes position should be changed, when it was pulled out the null.

That is why I use this Delete Without Children command, but I cannot set UNDO step here.

Man, I cannot figure this out by myself how to make it works. Please, guys, help me with this little script:(

Here is a COFFEE function that does exactly the same as Delete Without Children but you can insert in your Start/EndUndo calls. Basically it steps through the hierarchy of the selected object and removes the child objects and inserts them in the document's top hierarchy. Then it deletes the original selected object.

  
DeleteWithoutChildren(doc,obj)  
{  
  var child = obj->GetDown();  
  
  while (child)  
  {  
      var orig = child;  
      child = child->GetNext();  
  
      doc->AddUndo(UNDO_OBJECT_DEL,orig);  
      orig->Remove();  
        
      doc->InsertObject(orig,NULL,NULL);  
      doc->AddUndo(UNDO_OBJECT_NEW,orig);  
  }  
  
  doc->AddUndo(UNDO_OBJECT_DEL,obj);  
  obj->Remove();  
}  
  
main(doc,op)  
{  
  doc->StartUndo();  
  DeleteWithoutChildren(doc,doc->GetActiveObject());  
  doc->EndUndo();  
}  

cheers,
Matthias

FYI, there was a little mistake in the code of my last post.

doc- >AddUndo(UNDO_OBJECT_NEW,orig) has to called after inserting the object.

I corrected the code.

cheers,
Matthias
