更新一个整数的值（我想）

Question

我是python新手。目前我正在和一个朋友编写一个游戏。我们目前正在研制一种作战系统，唯一的问题是我们不知道一旦造成伤害，如何更新敌人的健康状况。代码如下

enemy1_health = 150

broadsword_attack = 20
rusty_knife = 10.5 

attacks = ["broadsword swing " +  str(broadsword_attack), "rusty knife jab " + str(rusty_knife) ]



while enemy1_health > 0: 
  while player_health > 0:
    enemy1_health = 150
    print(attacks)
    attackchoice = input("Choose an attack: ")
    if attackchoice == ("broadsword swing"):
      print (int(enemy1_health - 20))
    if attackchoice == ("rusty knife jab"):
      print (int(enemy1_health - 10.5))
  print("you died")
  quit()   
print("you cleared the level")```

Answer 1

你需要在打印声明之外更改敌人的生命值。 做：

 if attackchoice == ("rusty knife jab"):
    enemy1_health = enemy1_health - 10.5
    print(enemy1_health)

你也可以对其他攻击做同样的处理

您还可以在while循环中定义敌人的生命值。您需要在循环之外定义它

Answer 2

您需要使用以下语句更改打印语句之外的敌人生命值：

enemy1_health = enemy1_health - 20

或者像这样，做同样的事情：

enemy1_health -= 20

您还可以在每次循环循环时重置enemy1_运行状况，然后将其移除

你没有定义玩家的健康，定义它

你的循环会一直持续到你死

因此，您的代码应该更像这样：

enemy1_health = 150
broadsword_attack = 20
rusty_knife = 10.5
player_health = 100

attacks = ["broadsword swing " + str(broadsword_attack), "rusty knife jab " + str(rusty_knife)]

while enemy1_health > 0:
    print(attacks)
    attackchoice = input("Choose an attack: ")
    if attackchoice == ("broadsword swing"):
        enemy1_health -= 20
    if attackchoice == ("rusty knife jab"):
        enemy1_health -= 10.5
    print(enemy1_health)
    if player_health <= 0:
        print("you died")
        quit()
print("you cleared the level")

这仍然需要相当多的调整，如果是这样的话，这将是一个完整的工作游戏（基本上，如果你发送大刀攻击，你会赢，因为它们会造成更大的伤害）：

enemy1_health = 150
enemy1_attack = 10
player_health = 100
broadsword_attack = 20
rusty_knife = 10.5

attacks = ["broadsword swing " + str(broadsword_attack), "rusty knife jab " + str(rusty_knife)]

while enemy1_health > 0:
    print(attacks)
    attackchoice = input("Choose an attack: ")
    if attackchoice == ("broadsword swing"):
        enemy1_health -= broadsword_attack
    if attackchoice == ("rusty knife jab"):
        enemy1_health -= rusty_knife
    print(f'A hit! The enemy has {enemy1_health} health left.')
    if enemy1_health > 0:
        player_health -= enemy1_attack
        print(f'The enemy attacks and leaves you with {player_health} health.')
    if player_health <= 0:
        print("you died")
        quit()
print("you cleared the level")

Answer 3

必须在while循环上方定义健康状况，如下所示：

broadsword_attack = 20
rusty_knife = 10.5
attacks = ["broadsword swing " +  str(broadsword_attack), "rusty knife jab " + str(rusty_knife) ]
enemy1_health = 150


while enemy1_health > 0: 
  while player_health > 0: 
    print(attacks)
    attackchoice = input("Choose an attack: ")
    if attackchoice == ("broadsword swing"):
      enemy1_health -=20
      print (int(enemy1_health))
    if attackchoice == ("rusty knife jab"):
      enemy1_health -=10.5
      print (int(enemy1_health))
  print("you died")
  quit()   
print("you cleared the level")

避免在循环的每次迭代中将运行状况重新定义为150。并将这些值分配给health，而不仅仅是打印它。这意味着无论你做什么，敌人都不会失去健康。 此外，还有另一个问题，因为你从来没有减少球员的健康，这将导致一个无限循环
