如何在循环中从 randint 获得新结果? [英] How can I get new results from randint while in a loop?

问题描述

到目前为止我的代码:

from random import randint

Dice1 = randint(1,6)
Dice2 = randint(1,6)
Dice3 = randint(1,6)

DiceRoll2 = Dice1 + Dice2
DiceRoll3 = Dice1 + Dice2 + Dice3

class Item(object):
    def __init__(self, name, value, desc):
        self.name = name
        self.value = value
        self.desc = desc

sword = Item("Sword", 2, "A regular sword.")

class Monster(object):
    def __init__(self, name, health, attack):
        self.name = name
        self.health = health
        self.attack = attack

monster = Monster("Monster", 50, DiceRoll2)

Damage = DiceRoll3 + sword.value
NewHealth = monster.health - Damage

print("You see a monster!")

while True:
    action = input("? ").lower().split()

    if action[0] == "attack":
        print("You swing your", sword.name, "for", Damage, "damage!")
        print("The", monster.name, "is now at", NewHealth, "HP!")

    elif action[0] == "exit":
        break

意思是每次输入attack"都会得到DiceRoll3的随机结果(1到6的三个随机数，即3次)，加上剑的值，然后从怪物的起始生命值中减去该值.这一切顺利，直到我第二次输入攻击"，这会导致相同的伤害和相同的健康降低，而不是使用新值.我该如何正确执行此操作?

The intension is that with every time you enter "attack" you get a random result of DiceRoll3 (three random numbers from 1 to 6, that three times), add the value of the sword and substract that from the monster's starting health. This goes well until I enter "attack" a second time, which results in the same damage and the same reduced health being printed instead of using a new value. How can I properly do this?

推荐答案

把你的掷骰子放到一个单独的函数中，并在你的循环中计算 Damage 和 NewHealth.(另外，更新你怪物的健康.:))

Put your dice-rolling into a separate function and calculate Damage and NewHealth inside your loop. (Also, update your Monster's health. :))

from random import randint

def dice_roll(times):
  sum = 0
  for i in range(times):
    sum += randint(1, 6)
  return sum

class Item(object):
  def __init__(self, name, value, desc):
    self.name = name
    self.value = value
    self.desc = desc

sword = Item("Sword", 2, "A regular sword.")

class Monster(object):
  def __init__(self, name, health, attack):
    self.name = name
    self.health = health
    self.attack = attack

monster = Monster("Monster", 50, dice_roll(2))

print("You see a monster!")

while True:
  action = input("? ").lower().split()

  if action[0] == "attack":
    Damage = dice_roll(3) + sword.value
    NewHealth = max(0, monster.health - Damage)   #prevent a negative health value
    monster.health = NewHealth                    #save the new health value
    print("You swing your", sword.name, "for", Damage, "damage!")
    print("The", monster.name, "is now at", NewHealth, "HP!")

  elif action[0] == "exit":
    break

  if monster.health < 1:
    print("You win!")
    break
