Question

我正在尝试使用python制作类似于飞盘鸟的游戏，并使用超声波传感器作为控制器（它们都连接到树莓派）。如果距离<10，则小鸟向下移动，距离> 10的小鸟向上移动。我不太确定如何将距离与鸟的运动联系起来。

我尝试查找各种py游戏命令，但到目前为止我没有任何运气。

这是我到目前为止的代码。

pygame.init()

GPIO.setmode(GPIO.BCM)

GPIO.setup(TRIG, GPIO.OUT)
GPIO.setup(ECHO, GPIO.IN)

def get_distance():                      
    GPIO.output(TRIG, True)
    time.sleep(0.00001)
    GPIO.output(TRIG, False)

    while GPIO.input(ECHO) == False:
        start = time.time()

    while GPIO.input(ECHO) == True:
        end = time.time()

    sig_time = end-start            

    distance = sig_time / 0.000058 

    print ('Distance: {} cm'.format(distance))
    return distance


#   distance = get_distance()  ### stuck here

我希望能够使用超声波传感器作为控制器来移动鸟类。随时提供指向在线资源的链接，这些链接可以为我提供帮助，我想了解更多信息。

如何使用超声波传感器上下移动精灵？
