python - 文字冒险游戏 (Python) 中的项目类

Question

我正在用python制作一个文本冒险游戏。我有大部分基本项目设置，例如链接位置和保存功能。（我在设置保存功能时遇到了一点困难，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，我希望该项目位于某个位置（可能以与其他位置相互链接相同的方式链接到它），并且当玩家与它们交互时（例如拾取它），他们更新了该项目的位置。我希望用户必须输入命令并认识到他们需要该物品，并且一旦他们进入一个区域就不会被动地拾取该物品。（商店也没有功能，如果你能指点我怎么做最好+维护玩家的库存）

我知道这将包括很多东西，例如一个新类，以及一些专门规定哪些命令可以工作的新函数。我朝它开了一枪，但很快就撞到了墙上。如果你们中的任何人可以帮助我，那就太棒了。（另外，有更好/更快的方法来做某事，指出来，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']

至于捡东西，您可以在播放器类中有一个方法，将物品附加到播放器的库存列表中。如果您希望该项目位于特定位置，则可以在该位置提供一个可用项目列表，该列表可通过检查功能访问。

因此，Class Location:您可以在其中添加类位置：

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)

您不必像实施 Locations 那样实施项目，因为项目不会有任何邻居。

我希望用户必须输入命令并认识到他们需要该物品，并且一旦他们进入一个区域就不会被动地拾取该物品。

我猜这应该在你的检查函数中。除了在某个位置调用的检查函数应该产生该特定位置的项目列表。也许通过制作一个较小的版本来了解冒险游戏（您最喜欢的游戏之一）的工作原理可能会帮助您了解它们之间的抽象交互是如何的。我想添加一个具体的例子可以引发关于交互的讨论。祝你游戏好运！！
