我需要第158行中TypeError: '<' not supported between instances of 'int' and 'tuple'错误的帮助

该程序基本上是pygame中的一个游戏,您可以在该游戏中对着您的物体射击(这几乎无关紧要,但是如果有人希望能够理解这些变量,我认为它可以提供帮助)。

问题位于主循环中。我究竟做错了什么?

while run:
    last = pygame.time.get_ticks()
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            run = False
        elif event.type == my_event_id:
            x = random.randrange(screen_width - 64 * 2)
            index = random.choice(number)
            asteroids_on_screen.append(Enemy((x, rock.y), rock.width, rock.height))

    for a in asteroids_on_screen:
        if 0 < a.y < 500: # right here is the error
            a.y -= a.vel
        else:
            asteroids_on_screen.pop(asteroids_on_screen.index(a))

最佳答案

Enemy初始值设定项:def __init__(self, y, width, height)
您通过了:Enemy((x, rock.y), rock.width, rock.height))
因此,您的enemy.y实际上是(x, rock.y)的元组。当然,您不能将它与int进行比较。

下次,打印出您正在比较的内容,这样的错误将很明显。
