Question

我是一般的编码新手，我选择python作为我的第一语言学习，因为有些朋友说这很简单有趣。我决定制作一个基于文本的小游戏，除了一个问题，我的演示进展顺利。我无法对健康进行调整，经过大量的测试和搜索，我仍然无法弄清楚如何使这项工作。

def combat():
    global playerhealthpoints
    playerhealthpoints = 100
    def cavecombat():
        combatroundinput = raw_input("The round has begun. Do you Block, Dodge, or Run?").lower()
        if combatroundinput == "block":
            enemyattackroll = random.randrange(1,10)
            if enemyattackroll < 5:
                print "Enemy has missed their attack this round."
                cavecombat()
            elif enemyattackroll >= 5:
                enemydamageroll = random.randrange(1,10) / 2
                playerhealthpoints = playerhealthpoints - enemydamageroll
                print "You have taken %s damage." %enemydamageroll
                print "You have %s health remaining." %playerhealthpoints
                cavecombat()
        elif combatroundinput == "dodge":
            enemyattackroll = random.randrange(1,10) / 2
            if enemyattackroll < 5:
                print "Enemy has missed their attack this round."
                cavecombat()
            elif enemyattackroll >= 5:
                enemydamageroll = random.randrange(1,10)
                playerhealthpoints = playerhealthpoints - enemydamageroll
                print "You have taken %s damage." %enemydamageroll
                print "You have %s health remaining." %playerhealthpoints
                cavecombat()
        elif combatroundinput == "run":
            playerrunroll = random.randrange(1,10)
            enemyattackroll = random.randrange(1,10) * 2
            if enemyattackroll < 5 and playerrunroll <5:
                print "Enemy has missed their attack this round."
                print "You have failed to run from this encounter."
                cavecombat()
            elif enemyattackroll >= 5 and playerrunroll >= 5:
                enemydamageroll = random.randrange(1,10)
                playerhealthpoints = playerhealthpoints - enemydamageroll
                print "You have taken %s damage." %enemydamageroll
                print "You have %s health remaining." %playerhealthpoints
                print "You have succeeded in escaping the enemy."

            elif enemyattackroll < 5 and playerrunroll >= 5:
                print "Enemy has missed their attack this round."
                print "You have succeeded in escaping the enemy."

            elif enemyattackroll >= 5 and playerrunroll < 5:
                 enemydamageroll = random.randrange(1,10)
                 playerhealthpoints = playerhealthpoints - enemydamageroll
                 print "You have taken %s damage." %enemydamageroll
                 print "You have %s health remaining." %playerhealthpoints
                 print "You have failed to run from this encounter."
                 cavecombat()
        else:
            print "Learn to type, you suck."
            cavecombat()
    cavecombat()
combat()

这是我最近一次尝试让健康得到坚持，任何建议都值得赞赏。

您需要return健康。我是python的新手，所以最好检查一下。函数内部的IMO函数很奇怪。尝试将该函数分开，并使用return保留该值。

只是为了说明我的意思。

以下return pl值：

def cavecombat():
    combatroundinput = input("The round has begun. Do you Block, Dodge, or Run?").lower()
    if combatroundinput == "block":
        enemyattackroll = random.randint(1, 10)
        if enemyattackroll < 5:
            print("Enemy has missed their attack this round.")
            pl = 0
            return pl
        elif enemyattackroll >= 5:
            enemydamageroll = random.randint(1, 10) / 2
            pl = enemydamageroll
            print("You have taken %s damage." % enemydamageroll)
            return pl

现在可以完成以下工作：

damage = cavecombat（）

它将执行该函数，然后将pl的值置于损坏状态。

所以如果从上面打印说“你已经受到3次伤害。损害的价值是3。

如何修改全局变量的值，并使全局变量保留该新值？
