Control state machine type, main function is main loop of the game, when the state of running of the game starts setup_states setting function.

event_loop function is responsible for monitoring input (keyboard input and exit button), slef.keys save keyboard input.
done value update function detects the state, call state update function. If it detects the end of the current status, call flip_state function cleanup of the old state, and transition to the next state.
def update(self):
self.current_time = pg.time.get_ticks(http://www.amjmh.com/v/)
