六、对战游戏

class Riven:
    camp='Noxus'
    def __init__(self,name,
                 aggressivity=54,
                 life_value=414,
                 money=1001,
                 armor=3):
        self.name=name
        self.aggressivity=aggressivity
        self.life_value=life_value
        self.money=money
        self.armor=armor

    def attack(self,enemy):
        damage_value=self.aggressivity-enemy.armor
        enemy.life_value-=damage_value

class Garen:
    camp='Demacia'
    def __init__(self,name,
                 aggressivity=58,
                 life_value=455,
                 money=100,
                 armor=10):
        self.name = name
        self.aggressivity = aggressivity
        self.life_value = life_value
        self.money = money
        self.armor = armor
    def attack(self,enemy):
        damage_value=self.aggressivity-enemy.armor
        enemy.life_value-=damage_value

class BlackCleaver:
    def __init__(self,price=475,aggrev=9,life_value=100):
        self.price=price
        self.aggrev=aggrev
        self.life_value=life_value

    def update(self,obj):
        obj.money-=self.price  #减钱
        obj.aggressivity+=self.aggrev  #加攻击
        obj.life_value+=self.life_value  #加生命值

    def fire(self,obj): #这是该装备的主动技能，喷火，烧死对方
        obj.life_value-=1000  #假设火烧的攻击力是1000

r1=Riven('草丛伦')
g1=Garen('盖文')
b1=BlackCleaver()

print(r1.aggressivity,r1.life_value,r1.money)  #r1的攻击力，生命值，钱

if r1.money>b1.price:
    r1.b1=b1
    b1.update(r1)

print(r1.aggressivity,r1.life_value,r1.money) #r1的攻击力，生命值，钱

print(g1.life_value)
r1.attack(g1)  #普通攻击
print(g1.life_value)
r1.b1.fire(g1)  #用装备攻击
print(g1.life_value)  #g1的生命值小于0就死了
