Question

我是pygame的新手，并开始编写我的第一个游戏，当我试图碰撞球和积木时，我有一个问题，它就是这个。

 Traceback (most recent call last):
   File "C:\Users\Robert Hartley\Documents\Python\PYGAME32BIT\Ball Game.py",      line 152, in <module>
deadblocks = pygame.sprite.spritecollide(ball, block_group, True)
   File "C:\Users\Robert Hartley\AppData\Local\Programs\Python\Python35-32\lib\site-packages\pygame\sprite.py", line 1514, in spritecollide
for s in group.sprites():
 AttributeError: 'Block' object has no attribute 'sprites'

我不知道我做错了什么，我已经看到了其他人，并且已经调用了super（）。 init （），但我已经完成了那么，任何帮助都会很乐意接受，谢谢，

这里是我的完整代码 - 它可能没有任何好处所以任何帮助或提示也很好：D

导致错误是因为您覆盖此行中的block_group变量：

for block_group in deadblocks:
    ball.bounce()

pygame.sprite.spritecollide返回一个精灵列表，所以如果它包含精灵并且你循环它，名称block_group将被绑定到一个精灵对象，它不再引用一个组对象。这意味着下次你调用pygame.sprite.spritecollide(ball, block_group, True)时游戏会崩溃，因为第二个参数必须是一个组而不是一个精灵。

更改for循环中的名称以解决问题。

错误AttributeError：'Block'对象没有属性'sprites' - PYGAME
