附加函数变量

Question

我正在创建一个RPG游戏，我在其中使用健康和药水的功能。在每次遇到敌人后，玩家都会失去随机的健康状况。如果英雄剩下药水，他们就会获得给定的健康。我正试图保存下次遭遇时的健康和药水量，健康和药水从上次遇到时是相同的。如何为下一轮追加或保存变量???这是我对该功能的代码。

    import random
    health = 20
    potion = 5
    playerdamage = random.randint(0, 7)
    print("\nDuring the fight you took", playerdamage, "damage!")
    health -= playerdamage
    if potion > 0:
        print("You have a health potion to use!")
        health += 5
        potion -= 1
        print("You gained 5 health back and are now at",health,"health!")
        print("you have", potion, "health potion(s) left!")
    else:
        print("You have no health potions left!")
        print("You have", health, "health left\n")

    return health

这是完整代码

这里要考虑两个方面：如何组织代码以及如何组织数据。要反复“遇到敌人”，请使用子程序（即def语句）。要存储数据，您有两种选择：创建播放器类型或将数据存储在全局变量中。如果你可以保证游戏只涉及一个玩家，那么使用全局变量更容易，但是可扩展性更低 走全球路线：

import random
health = 20
potion = 5

def encounterEnemy():
    playerdamage = random.randint(0, 7)
    print("\nDuring the fight you took", playerdamage, "damage!")
    health -= playerdamage
    if potion > 0:
        print("You have a health potion to use!")
        health += 5
        potion -= 1
        print("You gained 5 health back and are now at",health,"health!")
        print("you have", potion, "health potion(s) left!")
    else:
        print("You have no health potions left!")
        print("You have", health, "health left\n")
    return health

然后，每次拨打encounterEnemy时，玩家的生命总数和药水都会相应调整。

创建新数据类型：

import random
class Player:
    def __init__(health, potion):
        self.health = health
        self.potion = potion
    def encounterEnemy():
        playerdamage = random.randint(0, 7)
        print("\nDuring the fight you took", playerdamage, "damage!")
        self.health -= playerdamage
        if self.potion > 0:
            print("You have a health potion to use!")
            self.health += 5
            self.potion -= 1
            print("You gained 5 health back and are now at", self.health, "health!")
            print("you have", self.potion, "health potion(s) left!")
        else:
            print("You have no health potions left!")
            print("You have", self.health, "health left\n")
        return self.health

currPlayer = Player(20, 5)
currPlayer.encounterEnemy()

创建新数据类型也很有用，因为它允许您将与问题相关的所有数据“捆绑”在一起。
