I have a game in which everything is controlled by gravity(). So after a while the device decides that nothing happens and the screen goes blank. Is there a way to avoid this? (without changing device auto-locking time settings)
Yes, you can add console.set_idle_timer_disabled(True) to your setup method to turn off auto-locking when your game starts.
You should also add a stop method to your scene (if you haven't already), and go back to the normal behavior there:
class MyScene (Scene):
# ...
def stop(self):
# Note: This will be called automatically when the scene is closed.
console.set_idle_timer_disabled(False)
