为什么在基于文字的冒险中选择种族时,我的角色表为什么不能与input()配合使用? python3.x

问题描述 投票:0回答:2

因此,这只是我将要遇到的一长串问题的开始。在这个基于文本的冒险中,我希望最终遇到困惑和多个分支路径,最终可以加入的派系,影响情况道德的选择对话(例如,质量效应或科托尔,但是基于文本的ish)等等。 。,但我觉得早期的设置对于这次学习非常重要。我还希望最终将其转换为PYQT5,并最终将UI托管在我为自己的投资组合建立的网站上。我只是想避免这种情况,以防您在这里经常看到我。下午给我建议,如果您愿意的话(因为我绝对可以使用守护神的帮助!)。

好的,眼前的问题是:

我有一个种族列表可供选择:

races = ['Human', 'Dwarf', 'Elf', 'Dragonborn', 'Tiefling', 'Half-Elf']

我想让玩家“选择比赛”。玩家键入想要玩的游戏后,会问“您确定吗?”|在这里我被困住了|如果播放器说“是”,则程序结束,我可以尝试继续构建此应用程序。如果玩家输入“否”,它不会返回到原始问题,而是允许他们再次回答。

所以,我尝试过的东西被定义为不同的方法:

Character.charRace()
Character.charDict()
Character.charTry()

我认为我的不良代码尝试就我所尝试的而言是不言而喻的。

class Character:

    def charRace():
        raceOptions = ['Human', 'Dwarf', 'Elf', 'Dragonborn', 'Tiefling', 'Half-Elf']

    Character.charRace()
    Character.charDict()
    Character.charTry()

所需结果示例:

>>> f'Choose a race {races}!:
>>> Human
>>> Do you want to play a Human?
>>> (Y    /    N)
>>> N
>>> Continue to browse...
>>> Choose a race: Human, Dwarf, Elf, Dragonborn, Tiefling, Half-Elf
>>> Dwarf
>>> Do want to play a Dwarf?
>>> Y
>>> You have chosen to play a Dwarf!

我尝试了几种不同的方法来获得所需的结果,但是它们似乎没有用。我应该建立一个有限状态机吗?我该怎么做?延长寿命并使代码模块化以便将来更新的最佳方法是什么?

您试图做的是建立一个菜单,用户可以在其中进行选择,并根据需要确认并重试他们的选择。

实现此目的的方法是使用无限while循环。本质上,您只想继续重复相同的选项集,直到用户做出选择或退出为止。

此外,请尽量使您的代码与用户所做的特定选择无关。我们关心他们从列表中选择一个项目;只要我们有必要在某种情况下检索它,我们就不必关心哪个项。在以下代码中,请注意,除了原始列表外,没有明确提及各个种族。

class Character:

有一种非常简单的方法。您需要通过import time导入“时间”模块或者您可以使用最简单的方法,在代码开头添加while True:。 !!不要忘记“:”之后的空格!
