python - 循环使用两个计数器

Question

我一直在家里使用 Python 制作一个基于文本的游戏，但在创建玩家和敌人之间的一小部分战斗时遇到了麻烦。战斗应该包括两次随机掷骰；一份给玩家，一份给外星人。如果外星人掷得比玩家高，则应该将+1添加到alien_wins计数器中，如果玩家获胜，则应该将+1添加到player_wins计数器中。

我想要发生的是，当player_wins计数器达到3时，循环将停止并产生一条消息，当alien_wins达到3时，也会发生同样的情况，但我在实现这一点时遇到了麻烦。任何帮助将不胜感激，谢谢!

import random
from Tkinter import *

def Fight():

    player_wins = 0
    alien_wins = 0

    while player_wins <= 3:

        player_roll = random.randint(0, 10)
        alien_roll = random.randint(0, 7)

        if player_roll > alien_roll:
            contents.set("You manage to fire a shot of your laser pistol and the alien backs off.")
            player_wins += 1
            return

        elif alien_roll > player_roll:
            contents.set("The alien reaches out and strikes you with its claws.")
            alien_wins += 1
            return

        elif alien_roll == player_roll:
            contents.set("You both grapple eachother and eventually back off.")        
            return

            if player_wins == 3:
                contents.set("You manage to overcome the alien. It leaps from wall to wall and crawls into the vents.")
                win = True
                break
            elif alien_wins == 3:
                contents.set("You lose the fight to the alien. Game Over!")
                break

base = Tk()

contents = StringVar()
display = Message(base, textvariable = contents, relief=RAISED)
display.pack()

enterbutton = Button(base, text = 'Try Again', command = Fight).pack()

base.mainloop()

当任一条件(点<= 3)为真时，您想继续战斗(循环)。您需要向 while 循环添加另一个条件。

您只想在战斗结束后从函数返回，因此删除所有这些返回并在战斗结束后添加循环之外的返回。另外，您只想在战斗结束后创建消息。

def Fight():

    player_wins = 0
    alien_wins = 0

    while player_wins <= 3 and alien_wins <= 3:

        player_roll = random.randint(0, 10)
        alien_roll = random.randint(0, 7)

        if player_roll > alien_roll:
            contents.set("You manage to fire a shot of your laser pistol and the alien backs off.")
            player_wins += 1

        elif alien_roll > player_roll:
            contents.set("The alien reaches out and strikes you with its claws.")
            alien_wins += 1

        elif alien_roll == player_roll:
            contents.set("You both grapple eachother and eventually back off.")        

    if player_wins == 3:
        contents.set("You manage to overcome the alien. It leaps from wall to wall and crawls into the vents.")
        win = True
    elif alien_wins == 3:
        contents.set("You lose the fight to the alien. Game Over!")
    return
