Question

我正在使用python开发游戏，一旦发生攻击功能，我就无法弄清楚如何消除健康。我可以运行该程序，并且攻击功能可以正常工作，它显示1到50之间的随机整数，但实际上并没有从castlehealth = 100

中夺走生命值。

在print("You attacked for " + str(self.attack))下，我将下一行留空，因为我不知道要输入什么，我尝试了许多不同的操作，只是无法从castlehealth那里夺走攻击力

这是我的代码：

import os
import time
from random import randint

class GameActions:
    def __init__(self):
        castlehealth = 100
        self.castlehealth = castlehealth
    def health(self):
        print("Castle health is: " + str(self.castlehealth))
        print()
    def attack(self):
        attack = randint(0, 50)
        self.attack = attack
        print("You attacked for " + str(self.attack))

def game():
    while True:
        game_actions = GameActions()
        print("What do you want to do?")
        print()
        print("attack, view hp")
        ans = input()
        if ans == "hp":
            game_actions.health()
        if ans == "attack":
            game_actions.attack()

Answer 1

您需要以下内容：

self.castlehealth -= attack

Answer 2

尝试类似self.castlehealth -= attack的操作。我还为您解决了一些潜在的缩进问题。

您的完整代码示例可能看起来像这样：

import os
import time
from random import randint

class GameActions:
    def __init__(self):
        castlehealth = 100
        self.castlehealth = castlehealth
    def health(self):
        print("Castle health is: " + str(self.castlehealth))
        print()
    def attack(self):
        attack = randint(0, 50)
        self.attack = attack
        print("You attacked for " + str(self.attack))
        self.castlehealth -= attack

def game():
    while True:
        game_actions = GameActions()
        print("What do you want to do?")
        print()
        print("attack, view hp")
        ans = input()
        if ans == "hp":
           game_actions.health()
        if ans == "attack":
           game_actions.attack()

说明：self.castlehealth是GameActions类的实例变量。函数GameActions.attack()创建一个新的attack变量作为随机整数，然后从self.castlehealth类的实例变量GameActions中减去该值。现在self.castlehealth将是更新后的值。考虑还应跟踪数据结构中的各种攻击和由此带来的健康状况，因为每次您拥有新的attack self.castlehealth和self.attack都会更改值，并且您将无法访问以前的值值。

上课时如何带走健康点？
