如何防止值在循环中重置？

Question

我一直在尝试为我的学校项目设置一个健康系统，但无论 monster_health 处于循环之外，我的朋友和我似乎无法修复，该值一直在重置这个。

代码：

monster_health = 100
while monster_health > 0:
    playeraction = input('Placeholder beast wants to fight you!!\n1) Basic Attack')
    print(monster_health)
    if playeraction == 1:
        monster_health = monster_health-7
        continue
    if monster_health <= 0:
        print('You killed the monster!! Gain nothing, this is a test you barbarian')
        break

输出：

Placeholder beast wants to fight you!!
1) Basic Attack
100 #should print 97 but fails to

Answer 1

替换

    if playeraction == 1:

和

    if playeraction == "1":

或：

    if int(playeraction) == 1:

因为您的输入是字符串格式而不是整数和 1 != "1"。

Answer 2

从你的代码来看，你在更新之前打印了怪物的生命值，所以它第一次是“100”（初始值）。

while monster_health > 0:
  playeraction = input('Placeholder beast wants to fight you!!\n1) Basic Attack')
  print(monster_health) # at this time, it is still 100
