返回动态计算

Question

我确信这是我能忽略的最容易的错误。曾经有过类似的问题，但不记得我是如何为了上帝的爱解决的。。。你知道吗

import random

enemy_hp = 100
player_hp = 100
enemy_hit = random.randint(1, 10)
enemy_meteor = 8
enemy_heal = 3
player_hit = random.randint(1,10)
player_fireball = 5
player_heal = 7

def eHit(enemy_hit):
    player_hp = 100-enemy_hit
    print (player_hp)

eHit(enemy_hit)

好吧，我编辑了它和它的工作意图，但即使有教程，我挣扎着与其他东西。你知道吗

How do i save the new value after the calulation so it doesnt always start at 100?

Answer 1

因为你已经编辑了原来的问题，现在你正在问

How do i save the new value after the calulation so it doesnt always start at 100?

你需要return这个新值并赋值给player_hp变量，然后移动enemy_hit的随机性，所以在调用eHit()之前它实际上需要一个新值，就像这样

import random

enemy_hp = 100
player_hp = 100
enemy_meteor = 8
enemy_heal = 3
player_hit = random.randint(1,10)
player_fireball = 5
player_heal = 7

def eHit(enemy_hit, player_hp):
    player_hp = player_hp - enemy_hit
    return player_hp

while player_hp > 0:
    enemy_hit = random.randint(1, 10)
    player_hp = eHit(enemy_hit, player_hp)
    print (player_hp)

为了测试，我在里面放了一个while player_hp > 0

考虑到这一点，我会再做一次稍微不同的操作，下面的代码让您可以自己尝试：

import random


player_hp = 100

def random_hit(start = 1, stop = 10):
    return random.randint(start, stop)

def enemy_hit(player_hp):
    return player_hp - random_hit()

while player_hp > 0:
    player_hp = enemy_hit(player_hp)
    print (player_hp)

现在您可以使用默认值调用random_hit()，或者使用更改的参数来调用像random_hit(20, 30)这样的“较大”点击，您也可以从其他函数调用random_hit()，无需双重赋值。你知道吗

你可以更进一步，因为命中就是命中，不管谁命中谁，所以没有双重功能，比如：

import random


player_hp = 100
enemy_hp = 100

def hit(hp, start = 1, stop = 10):
    return hp - random.randint(start, stop)

while player_hp > 0:  ## while loop only for testing purposes
    # for a enemy hitting a player with normal force, call this:
    player_hp = hit(player_hp)
    print (player_hp)

while enemy_hp > 0:  ## while loop only for testing purposes
    # for a player hitting an enemy with extra force, call this:
    enemy_hp = hit(enemy_hp, 10, 20)
    print (enemy_hp)

Answer 2

print(eHit)是错误的；eHit是函数而不是变量。你应该把它叫做print(eHit(somthing))

仅根据开始时变量声明的名称，我猜您的意思是print(eHit(enemy_hit))

然后会遇到这样的问题：player_hp是一个局部变量，在赋值之前使用，所以现在需要更改eHit()

def eHit(enemy_hit, player_hp):
    player_hp -= enemy_hit
    return player_hp - enemy_hit

你的打印声明现在

print(eHit(enemy_hit, player_hp))

您定义的其他函数也是如此。你知道吗
