Python数字不会随机化

Question

我一直在做一个格斗游戏，但伤害不会随机化。你知道吗

from random import randint
import time
#playerHealth = 20 
#trollHealth = 10
#dragonHealth = 15
#playerDamage = randint(0,5)
#trollDamage = randint(0,4)
#dragonDamage = randint(0,7)
#slay = True
#######Variables.

#print("""Random fight""")




def fight(enemy):

    playerH = 20 
    trollH = 10
    dragonH = 15
    playerD = randint(0,5)
    trollD = randint(0,4)
    dragonD = randint(0,7)
    slay = True

    if enemy == "troll":
        enemyH = trollH
        enemyD = trollD
    elif enemy == "dragon":
        enemyH = dragonH
        enemyD = dragonD
    else:
        print("Invalid")

    print"You are fighting a ", enemy
    while slay:
        print"Your health:",playerH
        print"Enemy health:",enemyH
        time.sleep(1)

#Enemy still attacks after death(test for death after each attack. Function?
#Damage doesn't vary
#Speed too fast at parts

在函数中，我希望它保持随机伤害，所以我为每个角色设置一个randint。但是，比如说我想和一条龙战斗，战斗就开始了，如果玩家先造成4点伤害，龙先造成2点伤害，那么在整个战斗中他们只会造成4点和2点伤害。为什么？我该怎么修？你知道吗

提前谢谢你能给我的任何帮助。你知道吗

Answer 1

你可以用这一行选择伤害金额：

 playerD = randint(0,5)

然后在之后的几行进入循环：

 while slay:

之后你再也不会造成伤害，所以它永远不会改变。你知道吗

基本上，你在开始玩之前先掷骰子，然后把它放在桌子上，每次你想要一个新的数字时都会瞥一眼。在游戏过程中，你需要把它捡起来再掷一次，也就是说，在循环中选择一个新的随机数。你知道吗

我有点想起this xkcd comic。你知道吗

Answer 2

在以下函数中指定randint值：

def fight(enemy):
    playerH = 20 
    trollH = 10
    dragonH = 15
    playerD = randint(0,5)
    trollD = randint(0,4)
    dragonD = randint(0,7)

import random
rand_value=   random.randint(0,10)

for i in range(5):
    print rand_value
2
2
2
2
2


for i in range(5):
    print random.randint(0,5)
2
1
3
2
5

然后输入while slay loop，这样循环中的值就不会改变。 您需要在循环中设置randint值。你知道吗
