如何在不獲得 2 個不同數字的情況下從敵人 HP 中減去 Randint 在 while 循環中生成的數量？

Question

如果您運行代碼，您應該會看到打印例如“14”，但它會從敵人的 HP 中收回其他東西。

計算每個“法術”的攻擊傷害：

from random import randint
import time


class Player(object):
    def __init__(self, health):
        self.health = health

    @staticmethod
    def use_heal():
        return randint(9, 21)

    @staticmethod
    def attack_slice():
        return randint(5, 29)

    @staticmethod
    def attack_bash():
        return randint(11, 18)

class Enemy(object):
    def __init__(self, health):
        self.health = health

    @staticmethod
    def enemy_attack():
        return randint(9, 19)

用於設置 HP：

player = Player(100)
enemy = Enemy(100)

作為“游戲”的循環：

while True:
    print(f"Your hp: {player.health}\nEnemy hp: {enemy.health}\n")
    print("(1) Bash _ (2) Slice _ (3) Heal")
    attack_choice = int(input(">>"))
    
    if attack_choice == 1:
        print(f"You hit for {Player.attack_bash()}")
        enemy.health -= Player.attack_bash()
    
    elif attack_choice == 2:
        print(f"You hit for {Player.attack_slice()}")
        enemy.health -= Player.attack_slice()
    
    elif attack_choice == 3:
        print(f"You heal for {Player.use_heal()}")
        player.health += Player.use_heal()

Answer 1

當它調用 Player.attack_* 時，它會返回一個隨機值來打印，然后第二次調用它來實際傷害敵人，因此它可能是一個不同的值。 它應該做的是調用一次，將其存儲在一個變量中並使用該變量

while True:
    print(f"Your hp: {player.health}\nEnemy hp: {enemy.health}\n")
    print("(1) Bash _ (2) Slice _ (3) Heal")
    attack_choice = int(input(">>"))
    
    if attack_choice == 1:
        damage = Player.attack_bash()
        print(f"You hit for {damage}")
        enemy.health -= damage
    
    elif attack_choice == 2:
        damage = Player.attack_slice()
        print(f"You hit for {damage}")
        enemy.health -= damage
    
    elif attack_choice == 3:
        damage = Player.use_heal()
        print(f"You heal for {damage}")
        player.health += damage

問題是您要為每種情況生成兩個隨機數：一個是打印的，另一個是減去/添加的。

...
print(f"You hit for {Player.attack_bash()}") # Generates a random number
enemy.health -= Player.attack_bash() # Generates another random number
...

您需要使用一個臨時變量，以便您可以兩次使用相同的值：

...
damage = Player.attack_bash()
print(f"You hit for {damage}")
enemy.health -= damage
...
