而不是递归调用

game\u state.main\u game2（）

则需要设置

game\u state.state==“main\u game2”

：

text_y=text.get_rect（）.height
如果启动
main_game2
中的代码，则该代码似乎与
main_game2
中的代码相同，只是
main_game2
添加了炸弹。这是正确的吗？是的，因为这个想法是在每个关卡后逐渐增加更难的机制，而不是改变游戏状态。您将其作为函数调用，但在任何时候都不会更改“self.state='main_game'，因此它总是设置为该值。因此，状态管理器总是将其视为“主游戏”，这使得它现在变得更有意义，但我不确定当我试图使其触发时，我将如何为selfstate切换到下一个游戏状态创造条件，特别是当游戏结束/玩家在工具更新中达到获胜所需的分数时获胜，检查分数并将游戏状态更改为main_game2。之后我应该做什么？
