有什么不对？ TypeError：__init __（）需要3个参数（给出2个）

Question

有人可以帮我找出错误吗？我不知道我做错了什么。

只有当我进入main.py并尝试运行游戏时才会出现此错误。

Answer 1

的这个错误告诉你到底是怎么回事。 Player类在实例化时会期待两个参数（以及自动传递的“self”）：x和y。但是你只是用display_height/2来实例化它，这只是一个参数。

您不应该发布所有不相关的代码，而应该查看回溯事件，告诉您哪一行发生了错误，如果您无法弄清楚发生了什么，您应该只发布相关内容部分。

Answer 2

在球员类的构造函数，它需要3个参数明确，一个是自己和另外两个，但在初始化类的对象，您需要提供参数y太

你只提供一个参数
