Question

当我尝试运行游戏时，代码会尝试为错误的精灵运行一个方法。我认为该行＆＃34; player.handle_keys（）＆＃34;问题是，当我运行它时，它说它无法找到＆＃34; handle_keys（）＆＃34;流星＆＃34;的方法类。我没有一条线来运行＆＃34; meteor.handle_keys（）＆＃34;因为这个类不应该有这个方法。

以下是代码：

你在for循环中覆盖了玩家

# Check the list of collisions.
for player in blocks_hit_list:
    score +=1
    print(score)

将其更改为其他内容并且一切都会很好

# Check the list of collisions.
for something_else in blocks_hit_list:
    score +=1
    print(score)
