#main game loop
while True:

这是我一直在研究的战斗模拟器的代码。它首先导入我制作的一个模块，该模块由一个名为“dice”的类组成，我用它来随机生成数字。接下来是定义等级，属性包括hp，maxhp，装甲等级，“击中装甲等级0”，突击调整和先攻调整，以及允许您攻击怪物的攻击，退出战斗的逃跑和治疗的方法这会给你的角色更多的生命值。程序继续定义生成 goblin 的 spawn_goblin() 函数（这在循环的第一次迭代中工作得很好）。然后进入非常简单的战斗部分；它所做的只是检查谁先走，然后让你攻击、逃跑或治愈自己。请忽略“治愈”和“逃离” 方法，这些工作得很好。当我攻击妖精时会出现问题。它没有杀死妖精并生成另一个妖精，而是创建了一个无限循环，上面写着“恭喜你杀死妖精”

解决方案

while (goblin.hp <= 0):
           print("congratulations you killed the goblin")

我认为您的这部分代码是错误的。while应该是，if因为您只想检查地精是否已经死亡，并运行一些代码一次。一旦妖精的生命值小于或等于0，该print语句将永远循环，因为表达式goblin.hp <= 0将始终返回True。

编辑：现在我认为您的代码错误的地方是：

while attack_flee_heal != 'attack' or 'flee' or 'heal':
               if attack_flee_heal == 'attack':
                   MrHezy.attack(goblin1)
               elif attack_flee_heal == 'heal':
                   MrHezy.heal(MrHezy)
                    ...

我认为您错过了break第一个if（此外，在这里使用 an 而不是 aif attack_flee_heal == 'attack' 更合适，因为正如我上面提到的，您只想检查一次.ifwhile
