Python while True loop not iterate over when 运行我的游戏

Question

我一直在研究这款奇幻战斗游戏，它按预期工作，尽管在最后开始游戏的 while True 循环没有迭代。我尝试使用 continue 但没有成功。我已经包含了一个流程图来直观地显示游戏的逻辑。我没有收到任何错误，应该是无限的循环只是在最后停止而不是重新开始。我可以让它迭代直到到达 break 之一吗？

# Player
wizard = "Wizard"
elf = "Elf"

# Player health
wizard_hp = 70
elf_hp = 100

# Dragon health and damage force

Answer 1

您的主要问题是您将 break 语句放在 print 语句之前，这意味着 while 循环在到达打印语句之前停止。

例如：

    # If dragon health is negative or null - game over
    elif dragon_hp <= 0:
        break #Break should not be here
        print(f'The Dragon lost the battle!')
    # If player health is negative - game over
    elif my_hp <= 0:
        break #Break should not be here
        print(f'The {character} lost the battle!')

相反，尝试：

    # If dragon health is negative or null - game over
    elif dragon_hp <= 0:
        print(f'The Dragon lost the battle!')
        break
    # If player health is negative - game over
    elif my_hp <= 0:
        print(f'The {character} lost the battle!')
        break

另外，一个提示：你应该为你的角色使用类，因为它更容易管理类。它将角色和它们的变量保持在一起，因此您在创建新角色时不必经常创建超过 1 个变量。

您的角色示例：

class character:
    def __init__(self,name,damg=0,hp=0):
        self.damage=damg
        self.hp=hp
        self.name=name

然后您将创建一个新角色，例如：

wizard=character("Wizard",150,70)

调用每个属性，如：

wizard.hp
# returns 70
wizard.name
# returns "Wizard"
wizard.damage
# returns 150

如果你保留这样的字符，这意味着你可以运行更有效的代码，例如我会把新的 character 对象放在一个列表中，然后进行攻击for 循环遍历角色列表并打印出他们造成的伤害、他们的生命值和他们的名字。例如

character_list=[wizard,elf,human] #some imaginary list
for x in character_list:
    print(f"{x.name} attacked the dragon!")
    print(f"{x.damage} was dealt.")
    print(f"{x.name} has {x.hp} left")

此外，您可以照常编辑这些内容。例如，从上面获取我们的向导：

# oh no! some event caused your wizard to lose health!
wizard.hp-=10
# returns 60 when called again

我希望这是一个令人满意的解释。
