我对python很新，我无法弄清楚什么是错的。我试图让子弹出现并移动，但它不会那样做，它会被卡在玩家身上。我的代码有点混乱，但现在是：

很抱歉，但很难帮助您解决这个问题，因为代码有点麻烦。我不能自己尝试也不改变它，特别是因为你加载了计算机上的许多图像。尽量使其更易于管理，以便我们更容易查明问题。您可以按照以下步骤操作：
至于试图回答你的问题。在你的代码中没有任何地方存在一颗子弹...你的意思是球吗？在那种情况下，你会做一些我不太了解的特殊事情。
document.array = array我认为你打算做for ball in ballGroup:
Ball = ball(screen, 64,64).update()
，因为知道你在每个游戏循环的64,64位创造新球。这可能是问题所在。另外，将变量命名为小写，将命名为大写。如果您希望其他人能够轻松阅读和理解您的代码，那么遵循这些约定非常重要。
