基于文本的游戏中库存和房间系统的困难

Question

我是一个相当新的程序员，几年来一直在苦苦挣扎，因为我曾短暂接触过几种语言。我试图最终牢牢掌握 Python，为此我目前的项目是设计一个简单的基于文本的游戏，例如“Zork”。

我已经成功地为每个房间使用函数制作了一个非常简单的版本，但是这根本无法推广。在我解释我目前做得不好的地方之前，我将链接代码。现在你可以看到，这是一种非常低效的房间建造方式，因为它需要大量的代码，除了这个确切的游戏，我不能用它来做任何事情。

首先我创建了一个列表用作玩家库存

    inventory = []


def addToInventory(item):
    inventory.append(item)

这是我用来制造武器的类，也是我的麻烦开始的地方。该类工作正常，我什至可以成功地将它的实例添加到我的库存列表中。

class Weapon:

    def __init__(self, name, damage, speed, weight):
        self.name = name
        self.damage = damage 
        self.speed = speed
        self.weight = weight

sword = Weapon("Sword", 7, 5, 5)
knife = Weapon("Knife", 5, 7, 3)
stick = Weapon("Stick", 2, 3, 3)

这是我尝试设计的用于创建房间的类。它尚未实施。现在我面临的问题是无法将 Weapon 类的实例添加到 Roominv 的参数中。例如，我不能使用武器类的剑实例作为房间内容的参数，它告诉我剑是未定义的。

Entrance = Room("You are at an entrance", "N", "Search the ground", sword)

现在我对这个项目的目标真的是学习，所以我不想要任何代码，但我是否走在正确的道路上？如何将武器类的某些实例与某些房间联系起来？我应该改用字典来建造房间吗？如果我应该使用字典，我必须为每个房间创建一个单独的字典还是嵌套字典？

我已经搜索了很多这些问题的答案，因为我确信有人问过类似的问题，但我似乎无法找到一个直接的答案。

class Room:

def __init__(self, description, exits, actions, Roominv): #Runs every time a new room is created
    self.description = description
    self.exits = exits
    self.actions = actions
    self.Roominv = Roominv

我将首先添加更多结构，将房间的定义与 IO/动作评估分开。

在维护状态方面，一种可能性（以introSword 为例）是修改操作中包含的Room，从而更改未来可用的操作。

您必须更改 Python 3 的 input 和 output 定义。希望这些是唯一需要的更改。

import traceback as tb

try:
  input = raw_input

  def output(*args):
    print ''.join(map(str,args))

  inventory = []

  class Weapon:
    def __init__(self, name, damage, speed, weight):
      self.name = name
      self.damage = damage 
      self.speed = speed
      self.weight = weight

    def __repr__(self):
      return self.name

  sword = Weapon("Sword", 7, 5, 5)
  knife = Weapon("Knife", 5, 7, 3)
  stick = Weapon("Stick", 2, 3, 3)

  class Room:
    def __init__(self,description,exits,actions,others=[]):
      self.description = description
      self.exits = exits
      self.actions = actions
      self.others = others

    def render(self):
      output(self.description)

      if self.actions:
        output('You can:')
        for id,name,_ in self.actions:
          output(id,'. ',name)

      choice = input('>>> ').upper()

      for id,_,action in self.actions:
        if choice == id.upper():
          action(self)
          break
      else:
        for id,action in self.others:
          if choice == id.upper():
            action(self)
            break
        else:
          output('I can\'t understand that command')
          self.render()

  quit = False

  while not quit:
    def introstrtBegin(room):
      intro.render()

    introstrt = Room(
