我正在制作类似太空入侵者的游戏。我已经完成了第一个第一级，有4行10个外星人。我想添加另一个级别，其中有4行17个外星人使其变得困难并缩短时间限制。我已经创建了一个单独的模块名称'LEVEL2'，这是我在第一级完成后尝试导入和运行的。有人可以帮我解决这个问题。
提前致谢

答案 0 :(得分：0)
将第1级中的所有内容除类定义外，并将其放入具有合理名称的函数中，例如“init”和“playGame”。让他们成为一个名为“Level”的班级的成员。
注意Level 1和Level 2中哪些方面有所不同。将这些参数不同的参数添加到Level的__init__成员中，并使用它们初始化一些将由其{{1}重用的局部变量会员。
现在确保playGame和init函数适用于这两个级别。
重写每个级别的所有代码是没有意义的。这样，您可以拥有任意数量的级别。
