  i wish it were that easy...

  see my_sprite.py 

...
    def on_animation_end (self):

        # we're already running when initialised so we
        # have to shut it off until we restart it again
        # but we only have to do this once as from then on
        # each animation will check the global flag to see
        # if it should run
#        print ("AF AC ", self.animation_foo, self.animation_count)
        self.animation_foo = False
        self.animation_count += 1
        if ((self.animation_initial_turn_it_off == True) and
            (self.animation_running == True)):
            print ("initial shut down animation AR True")
            pyglet.clock.unschedule(self._animate)
            self.animation_initial_turn_if_off = False
            ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

            self.animation_running = False
            pprint.pprint(MySprite.__mro__)
            pprint.pprint(MySprite.on_animation_end)
        elif ((self.animation_initial_turn_it_off == True) and
            (self.animation_running == False)):
            # we shouldn't get here, but just in case
            # just turn it off again...
#            print ("initial shut down animation AR False")
            self.animation_initial_turn_if_off = False
