Python 基于文本的 RPG 中的保存/加载系统

Question

我试图在我的 Python RPG 中获得一个保存/加载系统，但只能部分弄清楚如何完成这项工作。我已经看到关于这个主题的其他问题，但没有一个真正适合我正在做的事情。

class Player:
    def __init__(self, name):
        self.name = name
        self.base_defe = 0
        self.weap = "Rusty Sword"
        self.wbow = "None"
        self.armH = "Worn Helmet"
        self.armB = "Worn Shirt"
        self.armA = "Worn Gloves"
        self.armL = "Worn Pants"
        self.armF = "Worn Boots"
        self.gold = 1000
        self.orichalcum = 0 
        self.base_stre = 1
        self.base_magi = 1
        self.base_rang = 1
        self.maxmana = 100
        self.mana = self.maxmana
        self.level = 1
        self.exp = 0
        self.maxexp = 100
        self.expdiff = 50
        self.pots = 0
        self.arrows = 0
        self.q1c = False
        self.q2c = False
        self.q3c = False
        self.q1 = False
        self.q2 = False
        self.q3 = False
        self.QuestActive = False
        self.qtitle = "None"
        self.maxhealth = 100 + self.defe
        self.health = self.maxhealth
        self.inventory = ["Rusty Sword", 
                          "Worn Shirt", 
                          "Worn Pants", 
                          "Worn Boots",
                          "Worn Helmet",
                          "Worn Gloves"]
        self.spells = []

我还有一个名为 PlayerIG 的变量来表示玩家，但它是在一个函数中设置的，所以当我尝试加载游戏时，我不断收到类似 PlayerIG 未定义的消息。我尝试使用 pickle 创建一个保存/加载系统并将所有内容都放入字典中。保存它可以正常工作，但加载它肯定不行，因为每当我尝试全部加载时，变量都会被重置。我不知道如何使它正常工作，但我们将不胜感激。

给我最大问题的部分是：

def name():
    os.system('clear')
    PlayerIG = Player(raw_input("What is your name?"))
    print ("Prints story")

原因是 PlayerIG 是为了代表玩家，但每当我尝试加载保存文件时：

def load():
    os.system('clear')
    with open('savefile', 'rb') as f:
        data = pickle.load(f)
    print "Loaded last save state..."
    option = raw_input(" ")
    #data is equal to PlayerIG

它给了我错误，例如 PlayerIG 不存在，或者每当我在函数之外设置 PlayerIG 时，它会将 PlayerIG 设置为默认统计数据，并且它会加载游戏，将所有玩家统计数据设置为默认值，而不是加载他们保存的统计数据.

我只需要对你的类定义进行一次更正：self.maxhealth = 100 + self.defe 应该是 self.maxhealth = 100 + self.base_defe（我想这就是你的意思）。

这是一个在 OS X 上的 python 3.4.2 中运行并且似乎运行良好的测试：

import pickle

class Player:
    def __init__(self, name):
        self.name = name
        self.base_defe = 0
        self.weap = "Rusty Sword"
        self.wbow = "None"
        self.armH = "Worn Helmet"
        self.armB = "Worn Shirt"
        self.armA = "Worn Gloves"
        self.armL = "Worn Pants"
        self.armF = "Worn Boots"
        self.gold = 1000
        self.orichalcum = 0 
        self.base_stre = 1
        self.base_magi = 1
        self.base_rang = 1
        self.maxmana = 100
        self.mana = self.maxmana
        self.level = 1
        self.exp = 0
        self.maxexp = 100
        self.expdiff = 50
        self.pots = 0
        self.arrows = 0
        self.q1c = False
        self.q2c = False
        self.q3c = False
        self.q1 = False
        self.q2 = False
        self.q3 = False
        self.QuestActive = False
        self.qtitle = "None"
        self.maxhealth = 100 + self.base_defe
        self.health = self.maxhealth
        self.inventory = ["Rusty Sword", 
                          "Worn Shirt", 
                          "Worn Pants", 
                          "Worn Boots",
                          "Worn Helmet",
                          "Worn Gloves"]
        self.spells = []

p = Player('Fred')
p.exp = 100
p.gold = 5000

with open('fred.player', 'wb') as f:
    pickle.dump(p, f)

with open('fred.player', 'rb') as f:
    p2 = pickle.load(f)

print('Loaded player "%s" with %d exp and %d gold.' % (p2.name, p2.exp, p2.gold))
