当玩家的回合数= 6时程序退出。蟒蛇战列舰游戏

Question

我正在用python制作一个2人战舰游戏。我已经让每个'游戏'总共有6回合（每个玩家3回合），之后会出现一条消息，说'转数已经结束'。

一旦发生这种情况，他们将被要求再次玩。如果他们回答'是'或'是'，游戏应该重新加载。但事实并非如此。板加载但程序退出。我相信问题在于我的play_again（）函数，但我不太确定它是什么。

我想让玩家可以玩他们想玩的游戏，直到他们决定回答“否”或“n”。我如何去实现这个？

from random import randint 


game_board = [] 

player_one = { 
    "name": "Player 1", 
    "wins": 0, 
} 

player_two = { 
    "name": "Player 2", 
    "wins": 0, 
} 

colors = {"reset":"\033[00m", 
      "red":"\033[91m", 
      "blue":"\033[94m", 
      "cyan":"\033[96m" 
       }

Answer 1

这也为我工作，当我在你的play_again添加了调用到main（）函数：

# Allows new game to start 
def play_again(): 

    positive = ["yes", "y"] 
    negative = ["no", "n"] 

    global ship_points 

    while True: 
     answer = input("Play again? [Y(es)/N(o)]: ").lower().strip() 
     if answer in positive: 
      ship_points = load_game(game_board) 
      main() 
      break 

     elif answer in negative: 
      print("Thanks for playing!") 
      exit() 

Answer 2

尝试修改main有：

turns = 0 
while turns < 6: 
    # Process turn... 
    if turns == 5: 
     # Show endgame board 
     if play_again(): 
      turns = -1 
    turns += 1 

而且具有play_again上积极投入['y', 'yes']和False否则返回True。

问题是您的play_again()呼叫在收到“Y”作为答案时，会加载该电路板，但只是返回。哪里？那么，到它被称为的地方 - for循环main()。不幸的是，这是for循环的最后一次迭代，所以循环结束，程序退出。

你应该已经把另一个循环周围的for循环：

while True: 
    for turns in range(6): 
     ...
