python - 创建具有相同属性的方法

Question

我正在为我的游戏开发人员创建代码。需要创建 5 个敌人和普通玩家实例的类。我已经得到它，所以它创建了其中一个的 5 个实例，但返回 <__main__.Player object at 0x020E3410>和另一个一样。他们都有相同的属性。我的代码:

class Player(object):
    def __init__(self, nm, am, wp, ht, tp, ide):
        self.name = nm
        self.ammo = am
        self.weapon = wp
        self.health = ht
        self.type = tp
        self.id = ide

class Enemy(object):
    def __init__(self, nm, am, wp, ht, tp, ide):
        self.name = nm
        self.ammo = am
        self.weapon = wp
        self.health = ht
        self.type = tp
        self.id = ide

    def __str__(self):
        values = "Hi my name is " + self.name + "\n" + "Ammo: " + str(self.ammo) + "\n" + "Weapon: " + self.weapon + "\n" + "Health: " + str(self.health) + "\n" + "I am a: " + self.type + "\n" + "ID #: " + str(self.id)
        return values

    def __str__(self):
        values1 = "Hi my name is " + self.name + "\n" + "Ammo: " + str(self.ammo) + "\n" + "Weapon: " + self.weapon + "\n" + "Health: " + str(self.health) + "\n" + "I am a: " + self.type + "\n" + "ID #: " + str(self.id)
        return values1

def main():
    Enemies = 0
    Players = 0
    while Players < 5:
        play1 = (Player("Joe", 5, "Machine gun", 22, "Hero", Players))
        print (play1)
        Players = Players + 1
        break
    while Enemies < 5:
        ene1 = (Enemy("Julian", 100, "Rocket Launcher", 1337, "Enemy", Enemies))
        print (ene1)
        Enemies = Enemies + 1

main()

您的 Enemy 类有两个 __str__ 方法，但您的 Player 类没有:

class Player(object):
    def __init__(self, nm, am, wp, ht, tp, ide):
        self.name = nm
        self.ammo = am
        self.weapon = wp
        self.health = ht
        self.type = tp
        self.id = ide

class Enemy(object):
    def __init__(self, nm, am, wp, ht, tp, ide):
        self.name = nm
        self.ammo = am
        self.weapon = wp
        self.health = ht
        self.type = tp
        self.id = ide

    def __str__(self):
        values = "Hi my name is " + self.name + "\n" + "Ammo: " + str(self.ammo) + "\n" + "Weapon: " + self.weapon + "\n" + "Health: " + str(self.health) + "\n" + "I am a: " + self.type + "\n" + "ID #: " + str(self.id)
        return values

    def __str__(self):
        values1 = "Hi my name is " + self.name + "\n" + "Ammo: " + str(self.ammo) + "\n" + "Weapon: " + self.weapon + "\n" + "Health: " + str(self.health) + "\n" + "I am a: " + self.type + "\n" + "ID #: " + str(self.id)
        return values1

您可能想要:

class Player(object):
    def __init__(self, nm, am, wp, ht, tp, ide):
        self.name = nm
        self.ammo = am
        self.weapon = wp
        self.health = ht
        self.type = tp
        self.id = ide

    def __str__(self):
        values1 = "Hi my name is " + self.name + "\n" + "Ammo: " + str(self.ammo) + "\n" + "Weapon: " + self.weapon + "\n" + "Health: " + str(self.health) + "\n" + "I am a: " + self.type + "\n" + "ID #: " + str(self.id)
        return values1

class Enemy(object):
    def __init__(self, nm, am, wp, ht, tp, ide):
        self.name = nm
        self.ammo = am
        self.weapon = wp
        self.health = ht
        self.type = tp
        self.id = ide

    def __str__(self):
        values = "Hi my name is " + self.name + "\n" + "Ammo: " + str(self.ammo) + "\n" + "Weapon: " + self.weapon + "\n" + "Health: " + str(self.health) + "\n" + "I am a: " + self.type + "\n" + "ID #: " + str(self.id)
        return values

顺便说一句，为了最大限度地减少重复代码，您可以创建一个基类，例如:

class BasePlayer(object):
    def __init__(self, nm, am, wp, ht, tp, ide):
        self.name = nm
        self.ammo = am
        self.weapon = wp
        self.health = ht
        self.type = tp
        self.id = ide

    def __str__(self):
        values = "Hi my name is " + self.name + "\n" + "Ammo: " + str(self.ammo) + "\n" + "Weapon: " + self.weapon + "\n" + "Health: " + str(self.health) + "\n" + "I am a: " + self.type + "\n" + "ID #: " + str(self.id)
        return values

然后使用继承创建Enemy和Player:

class Enemy(BasePlayer):
    # enemy related stuff

class Player(BasePlayer):
    # goody related stuff
