我是一个菜鸟程序员，在我的包含 while 循环的分配中遇到问题。
目前，我正在编写一款游戏的战斗系统，该游戏有两个需要相互循环的阶段（攻击和防御阶段）。它是作为一种方法创建的，我将能够在游戏中多次调用它。我原本打算让代码工作的方式是创建一个 while 循环，该循环将一直持续到演员的一个生命值达到 0。接下来，我在第一个 while 循环中嵌套了 while 循环，以使用满足嵌套循环条件的布尔值继续在两者之间切换。然而，在测试代码并尝试其他循环代码的方法后，它似乎卡在循环防御阶段而不是切换回攻击阶段。
我非常感谢反馈并帮助防止代码这样做。也忽略“使用项目”位代码，我还没有添加它作为选择，所以它现在只是文本。

defenceStance = true是赋值，而不是比较，因此while(defenceStance = true)将始终为真，因为它正在测试赋值是否成功。您需要使用==来比较值。但是由于您正在测试 true，因此您可以说while(defenceStance)因为 bool == true 将始终仅导致 bool 的值。
