我如何比较多个对象以查看它们之间的属性是否相等？

Question

[我是Python的业余爱好者，我正在尝试创建一个程序来确定我正在开发的游戏的主动性，其中一部分是确保两个角色的打号速度不同。”每个字符都是具有以下类代码的对象：

class Character(object):
        def __init__ (self, name, speed, agility, otick, tick):
                self._name = name
                self._speed = int(speed)
                self._agility = int(agility)
                self._otick = int(otick)
                self._tick = int(tick)

以及以下用于确定“刻度速度”的代码：

if createCharacter._speed == 0: createCharacter.set_otick(-1)
        elif createCharacter._speed == 1: createCharacter.set_otick(30)
        elif createCharacter._speed == 2: createCharacter.set_otick(27)
        elif createCharacter._speed == 3: createCharacter.set_otick(24)
        elif createCharacter._speed == 4: createCharacter.set_otick(21)
        elif 5 <= createCharacter._speed <= 6: createCharacter.set_otick(18)
        elif 7 <= createCharacter._speed <= 9: createCharacter.set_otick(15)
        elif 10 <= createCharacter._speed <= 11: createCharacter.set_otick(14)
        elif 12 <= createCharacter._speed <= 13: createCharacter.set_otick(13)
        elif 14 <= createCharacter._speed <= 15: createCharacter.set_otick(12)
        elif 16 <= createCharacter._speed <= 17: createCharacter.set_otick(11)
        elif 18 <= createCharacter._speed <= 22: createCharacter.set_otick(10)
        elif 23 <= createCharacter._speed <= 28: createCharacter.set_otick(9)
        elif 29 <= createCharacter._speed <= 34: createCharacter.set_otick(8)
        elif 35 <= createCharacter._speed <= 43: createCharacter.set_otick(7)
        elif 44 <= createCharacter._speed <= 61: createCharacter.set_otick(6)
        elif 62 <= createCharacter._speed <= 97: createCharacter.set_otick(5)
        elif 98 <= createCharacter._speed <= 169: createCharacter.set_otick(4)
        elif 170 <= createCharacter._speed <= 225: createCharacter.set_otick(3)
        createCharacter.set_tick(createCharacter._otick)

我想知道如何编写代码，以便在战斗中有三个或更多字符时，一个命令可以检查其中至少两个字符是否具有相同的“滴答”值，以便在执行倒数计时程序时，不会有两个字符同时达到0。

我的目的是在角色创建时进行比较检查，并且当角色的回合结束并且他们的“刻度”返回到其原始值（存储在“ otick”中）时。如果至少两个值相等，则程序将比较两个字符的“敏捷性”属性，以较低者为准，将1个添加到“滴答”中，然后进行另一个比较以确保未创建另一个并列。如果两个敏捷都相等，那么我希望它（本质上）掷骰子（基于所讨论的敏捷），而失败者获得+1。

谢谢您的考虑。

您可以重写Character类的比较方法（lt，le，gt，ge，eq和ne魔术方法）

例如，您可以执行以下操作：

import random

class Character(object):
        def __init__ (self, name, speed, agility, otick, tick):
                self._name = name
                self._speed = int(speed)
                self._agility = int(agility)
                self._otick = int(otick)
                self._tick = int(tick)

        def __gt__(self,other):
            if !isinstance(other,Character):
                 raise Exception("Invalid Comparison")

            if self.agility == other.agility:
                # if they have the same values you can "roll a dice"
                return random.randint(0,100) % 2 == 0

            # Here you can check and compare the values of self and other
            return self.agility > other.agility

现在，如果您与实例进行比较，

player1 = Character()
player2 = Character()

# Now you can compare them using normal operator and apply logic after

if player1 > player2: #if this are the same it will make a random choice
   player1.agility +=1
else:
    player2.agility +=2 # you could add any logic
