  Hi!
  
  Yes, you can create 9 times the same object in code and then call orxObject_SetPosition() on them, and store the positions in config so as to be able to change them without having to recompile:
  

  config:
  [Common]
  ObjectPositions = (0, 0, 0) # (100, 0, 0) # ...
  
  [MyGraphic]
  Texture = ...
  
  [MyObject]
  Graphic = MyGraphic
  
  code:
  orxConfig_PushSection("Common");
  
  for(orxS32 i = 0; i < orxConfig_GetListCounter("ObjectPositions"); i++)
  {
    orxVECTOR v;
    orxOBJECT *pstObject = orxObject_CreateFromConfig("MyObject");
    orxObject_SetPosition(pstObject, orxConfig_GetVectorList("ObjectPositions", i, &v));
  }
  orxConfig_PopSection();
  

  
  Or you can do it all in config and create only one object:

  config:
  [MyMainObject]
  ChildList = Object1 # Object2 # ...
  
  [ObjectBase]
  Graphic = MyGraphic
  
  [[email protected]]
  Position = (0, 0, 0)
  
  [[email protected]]
  Position = (100, 0, 0)
  ...
  
  in Code:
  
  orxObject_CreateFromConfig("MyParentObject");
  

  
  And if you move this object, all the children will move at the same time.

  Yes, I figured something like this alone, but what if I need to delete one (and only one) of this objects? Specifically after I click on it with mouse (Don't need full code of mouse clicks or so ).

  You have more than one option:
  - store every object manually in code when creating them one by one
  - store every object by listening to the orxOBJECT_EVENT_CREATE event (and only create the parent object)
  - go through all the objects when you need it and find the one you want (orxStructure_GetFirst/GetNext)
  - pick the object with orxObject_Pick() using the mouse position, in your case (the picking function looks only for object that have a greater Z than the position you give)
  
  There might be other ways, but I think those are the most common.

  What a comprehensive response. Picking object by mouse position looks like the best way for me. I'll try it out.
