【问题描述】：
我在 pygame 上做游戏，我遇到了一个问题，我正试图找出我面临的问题。我不知道解决方案。我收到以下错误消息：
我收到以下错误消息：
shark = enemy(-389,410,170,71,-389, 1360)
TypeError: enemy() takes no arguments
有谁知道错误在哪里？

我收到另一个错误：

有谁知道错误在哪里？
【问题讨论】：
-
请重新格式化您的问题以将代码编写为实际代码。使用界面顶部的括号。
-
错误提示
shark未定义。在您包含的代码中，我看不到您这样做的任何地方。我看到了fish = player(...)，但我在任何地方都没有看到shark = ...。也不是 Shark1、Shark2 或 Shark3，尽管您在redrawwindow()中使用它们。 -
我把敌人的所有代码都放好了，大家可以看到
