Well, you can add, in the layer where you are listening to on_key_press a
method
def exit_scene(self):
self.save()
# you have to decide what of the following is better for you:
director.pop() # quit this scene and goes to the one when you called
director.push()
scene = OtherScene(...)
director.replace(scene) # quits the current scene and goes to the
OtherScene instance
scene = OtherScene()
director.push(scene) # suspends the current scene going to to the
OtherScene instance,
# later you can return to the current scene
with director.pop()
def save(self):
# your code to save whatever needs saving
...
Then your on_key_press method should call self.end_scene() when it detects a
return press.
