PyObjectPlus
============

.. class:: PyObjectPlus

   PyObjectPlus base class of most other types in the Game Engine.

   .. attribute:: invalid

      Test if the object has been freed by the game engine and is no longer valid.

      Normally this is not a problem but when storing game engine data in the GameLogic module,
      KX_Scenes or other KX_GameObjects its possible to hold a reference to invalid data.
      Calling an attribute or method on an invalid object will raise a SystemError.

      The invalid attribute allows testing for this case without exception handling.

      :type: boolean
