Python - 布尔测试，而循环永远不会结束

Question

您好我正在尝试编程一个覆盆子pi Sense帽子，使用accelorometer在Matrix周围移动一个像素。想法是到红色区域获胜。然而，如果它击中绿色黄色或蓝色，游戏将以亏损告终。当它找到其中一种颜色时，可以将布尔变量e（game_over）更改为True，从而打破循环以停止游戏。

问题是当它读取颜色被点击时它将变量game_over更改为True，但是当它返回到while循环时它会变回False。我已经使用print语句对此进行了测试，看看会发生什么。

    elif maze[y][x] == g:
        sense.set_pixels(false)
        game_over = True
        sleep(1)
        sense.show_message('Vous avez perdu', scroll_speed=0.08)


while game_over == False:
    pitch = sense.get_orientation()['pitch']
    roll = sense.get_orientation()['roll']
    x,y = move_marble(pitch,roll,x,y)
    check_win(x,y)
    maze[y][x] = w
    sense.set_pixels(sum(maze,[]))
    sleep(0.1)
    maze[y][x] = e
sense.clear()

我确定它很小，我似乎无法找到它。
