我在python中制作一个文本冒险游戏。我有大多数基本项目设置，如链接位置和保存功能。 （设置保存功能有点困难，所以如果有更好的方法请告诉我）。
现在我想制作物品。具体来说，我希望项目位于一个位置（可能与其他位置相互链接的方式相关联），当玩家与它们交互时（例如，拾取它），他们更新了项目的位置。我希望用户必须输入命令并识别他们需要该项目，并且一旦他们进入某个区域就不会被动地拾取该项目。 （这家商店也是非功能性的，如果你能指点我最好的方法并保持玩家的库存，那将是一件好事。）
我知道这将包括很多东西，比如一个新类，以及一些新的函数，它们明确规定哪些命令可以工作。我已经开了一枪，但很快撞到了墙上。如果你们中的任何人能帮助我，那就太棒了。 （此外，有一种更好/更快的方式来做某事，指出它，我会考虑添加它）。
这是代码：
import pickle
import time
# Constants/Valid Commands
# This is a mess, ignore it unless it causes a problem.
invalidChars = '\"\'()*&^%$#@!~`-=_+{}[]\|:;<,>.?/'
validLogin = 'log in', 'log', 'saved', 'in', 'load', 'logging in', 'load game', 'load'
validNewGame = 'new', 'new game', 'new save'
directions = ['north', 'south', 'east', 'west']
possibleGenders = ['boy', 'girl']
examineCommands = ['examine yourself', 'look at yourself', 'my stats', 'my statistics', 'stats', 'statistics', 'examine statistics', 'examine stats']
invalidExamine = ['examine', 'look at' ]
stop = ['stop', 'exit', 'cancel']

# ACTUALLY WHERE THE PROGRAM STARTS
locations = {'woods': Location("The Woods", "You are surrounded by trees. You realize you are in the woods."),
'lake': Location("The Lake", "You go north and are at the lake. It is very watery."),
'town': Location("The Town", "You go north, and find yourself in town."),
'shop': Location("The Shop", "You go east, and walk into the shop. The shop owner asks what you want")
}
locations['woods'].addLink('north', 'lake')
locations['lake'].addLink('south', 'woods')
locations['lake'].addLink('north', 'town')
locations['town'].addLink('south', 'lake')
locations['town'].addLink('east', 'shop')
locations['shop'].addLink('west', 'town')
start()
至于拾取内容，您可以在播放器类中使用一种方法将该项目附加到播放器的清单列表中。如果您希望项目位于特定位置，则可以在位置处获得可通过检查功能访问的项目列表。
因此，在Class Location:中，您可以添加类位置：
def __init__(self, name, description):
self.name = name
self.description = description
self.linkedLocations = {} # stores linked locations in this dictionary
self.items = items # List of items on location
在Class Player:你可以添加，
Class Player:
def PickUp(self, Location, item):
Location.items.remove(item)
self.inventory.append(item)
您不必以实现Locations的方式实现项目，因为项目不会有任何邻居。
我希望用户必须输入命令并识别他们需要该项目，并且一旦他们进入某个区域就不会被动地拾取该项目。
我想这应该是你的检查功能。除了在某个位置调用的检查函数之外，应该生成该特定位置的项目列表。也许了解一个冒险游戏（你最喜欢的一个）如何通过制作一个较小的版本来工作可能有助于你理解它们之间的抽象交互是如何。我想添加一个具体的例子可以激发对交互的讨论。祝你好运！
