一、游戏解读

1、初始值

• 一个回合制游戏，每个角色都有hp和power，hp代表血量，power代表攻击力，hp的初始值为100，power的初始值为200

2、定义一个fight方法：

• final_hp = hp-enemy_power
• enemy_final_hp = enemy_hp-power
• 两个hp进行对比，血量剩余多的人获胜

class Game:
    hp = 1000
    power = 200

    def fight(self, enemy_power, enemy_hp):
        final_hp = self.hp - enemy_power
        enemy_final_hp = enemy_hp - self.power
        if final_hp > enemy_final_hp:
            print('我赢了')
        elif final_hp < enemy_final_hp:
            print('我输了')
        else:
            print('平局')

game = Game()
game.fight(1000, 200)

二、代码优化——继承

1、将角色的hp、和power通过传参传入

2、第二个角色，他叫后裔，后裔继承了角色的hp和power。并多了护甲属性

3、houyi_hp = hp+defense - enemy_power

class Game:
    def __init__(self, hp, power):
        self.hp = hp
        self.power = power

    def fight(self, enemy_power, enemy_hp):
        final_hp = self.hp - enemy_power
        enemy_final_hp = enemy_hp - self.power
        if final_hp > enemy_final_hp:
            print('我赢了')
        elif final_hp < enemy_final_hp:
            print('我输了')
        else:
            print('平局')


# 继承Game类
class HouYi(Game):
    # 如果在子类中重新定义了__init__，那么父类的__init__将会被覆盖
    def __init__(self):
        super().__init__(1000, 200)
        self.defense = 100
        
    def houyi_fight(self, enemy_hp, enemy_power):

        final_hp = self.hp+self.defense-enemy_power
        enemy_final_hp = enemy_hp-self.power
        if final_hp > enemy_final_hp:
            print('我赢了')
        elif final_hp < enemy_final_hp:
            print('敌人赢了')
        else:
            print('平局')


hp = 1000
power = 200
houyi = HouYi()
houyi.houyi_fight(hp,power)
# game = Game(hp, power)
# game.fight(1000, 200)
