python中的類和字典的問題

Question

我正在嘗試將舊的游戲引擎轉換為使用類而不是僅詞典的較新版本。

我的目標是從兩個不同的類中添加相似的鍵值，以修改播放器的統計信息。

class player:
    def __init__(self, name, level, xp, nextlvlxp, stats, inventory):
        self.name = ''
        self.level = 1
        self.xp = 0
        self.nextlvlxp = 25
        self.stats = {
            'str': [],
            'dex': [],
            'con': [],
            'int': [],
            'wis': [],
            'cha': [],
            'modstr': [],
            'moddex': [],
            'modcon': [],
            'modint': [],
            'modwis': [],
            'modcha': []
        }
        self.combat_stats = {
            'totalhp': [],
            'currenthp':[],
            'totalmp': [],
            'currentmp': [],
            'baseatk': [],
            'attack': [],
            'speed': [],
            'perception':[]

        }
        self.noncombat_stats = {
            'evasion': [],
        }
        self.inventory = {}


class Item():
    def __init__(self, name, description, stats, value):
        self.name = name
        self.description = description
        self.stats = {}
        self.value = value
class Weapon(Item):
    def __init__(self, name, description, stats, value):
        self.stats = stats
        super().__init__(name, description, value)

    def __str__(self):
        return "{}\n=====\n{}\nValue: {}\nStats: {}".format(self.name, self.description, self.value, self.stats)

class Sword(Weapon):
    def __init__(self):
        super().__init__(name="Sword",
                         description="A common shortsword",
                         stats = {
                             'str': 2,
                             'dex': 1
                         },
                         value = 10)

示例：項目“ sword”“ str” +播放器“ str” =播放器“ modstr”

我希望能夠將這些值以及dex的下一個值相加，我希望以非重復的方式進行。 我不太確定從哪里開始，我今天才剛剛學會如何編寫類。 有什么方法可以瀏覽字典並將具有相同鍵的值相加？

這基本上就是您要執行的操作，但是由於您的默認屬性為空列表，因此我不確定您的情況。

a = {1: 2, 3: 4, 5: 6}
b = {1: 8, 3: 2, 7: 8}

for key in a:
    if key in b:
        a[key] += b[key]

例如：

class Pool:
    def __init__(self, value):
        self.value = value
        self.max_value = value

class Stats:
    def __init__(self, strength=0, dexterity=0, constitution=0, intelligence=0, wisdom=0, charisma=0):
        self.strength = strength
        self.dexterity = dexterity
        self.constitution = constitution
        self.intelligence = intelligence
        self.wisdom = wisdom
        self.charisma = charisma

    def __add__(self, stats):
        return Stats(
            self.strength + stats.strength,
            self.dexterity + stats.dexterity,
            self.constitution + stats.constitution,
            self.intelligence + stats.intelligence,
            self.wisdom + stats.wisdom,
            self.charisma + stats.charisma
        )

    def copy(self):
        return Stats(
            self.strength,
            self.dexterity,
            self.constitution,
            self.intelligence,
            self.wisdom,
            self.charisma
        )

    def __repr__(self):
        return str(vars(self))

class Equipment:
    def __init__(self):
        self.weapon = Weapon('None', 'None', 0, Stats())
        self.chest = Weapon('None', 'None', 0, Stats())
        self.hands = Weapon('None', 'None', 0, Stats())
        self.head = Weapon('None', 'None', 0, Stats())
        self.legs = Weapon('None', 'None', 0, Stats())

    def __repr__(self):
        return str(vars(self))

class Player:
    def __init__(self, name, next_xp, stats, inventory):
        self.xp = 0
        self.name = name
        self.stats = stats
        self.next_xp = next_xp
        self.inventory = inventory
        self.equipment = Equipment()

    def get_stats(self):
        stats = self.stats.copy()
        elist = vars(self.equipment)
        for v in elist:
            stats += elist[v].stats

        return stats

class Item:
    def __init__(self, name, description, value):
        self.name = name
        self.description = description
        self.value = value

class Weapon(Item):
    def __init__(self, name, description, value, stats):
        Item.__init__(self, name, description, value)
        self.stats = stats

    def __repr__(self):
        return str(vars(self))

def main():
    weapons = {}
    weapons['sword'] = Weapon('sword', 'common sword', 10, Stats(2, 1))
    weapons['intelligence sword'] = Weapon('intelligence sword', 'sword of intelligence', 10, Stats(2, 1, intelligence=1))

    player = Player('Me', 25, Stats(5, 4, 6, 3, 3, 4), {})
    print(player.get_stats())
    player.equipment.weapon = weapons['sword']
    print(player.get_stats())
    player.equipment.weapon = weapons['intelligence sword']
    print(player.get_stats())

main()
