我是一名新手程序员，我的作业包含while循环。
目前，我正在为一个游戏的战斗系统编程，该游戏有两个阶段需要在彼此之间循环（攻击和防御阶段）。它是作为一种方法创建的，我可以在游戏中多次调用它。我打算如何使代码工作是通过创建一个while循环来继续，直到其中一个actor的生命值达到0.接下来，我在第一个while循环中嵌套while循环以使用符合条件的booleans嵌套循环继续在两者之间切换。但是，在测试代码并尝试其他循环代码的方法之后，它似乎陷入了循环防御阶段并且没有切换回攻击阶段。
我真的很感激反馈并帮助阻止代码执行此操作。忽略＆＃34;使用项目＆＃34;我还没有添加它作为一个选择，所以它现在只是文本。

答案 0 :(得分：1)
defenceStance = true是一项任务，而非比较，因此while(defenceStance = true)始终为真，因为它正在测试分配是否成功。您需要使用==来比较值。但是因为你测试的是真的，你可以说while(defenceStance)，因为bool == true总是会产生bool的值。
