我正在制作b-ship游戏。我试图让用户点击ai，然后是用户，然后是ai等。我该如何管理？

修改 我添加了错误检查，但它似乎在无限循环中运行。有什么问题？
答案 0 :(得分：1)
您需要将应用程序拆分为两个循环;你把它们组合在一起，这是你混乱的根源。
第一个循环用于设置玩家的船只。这是一个无限循环，直到所有船只都正确放置。
使用计数器启动循环，这是最大数量的船只。
这是一个如何运作的想法
user_ships = [] # this will store the ship's coordinates
total_ships = 2 # How many ships a user can have
while len(user_ships) < total_ships:
coordinates = input('Please enter your ship coordinates: ')
if check_if_coordinates_are_valid(coordinates):
if check_if_spot_is_free(coordinates):
user_ships.append(coordinates)
else:
print('Sorry, that spot is already taken by your ship')
else:
print('Sorry, those are not valid coordinates')
接下来，让计算机随机放置自己的船只;和它一样的想法 用户的循环，而不是打印出任何错误消息，只是通过随机选择，直到找到合适的坐标：
computer_ships = []
while len(computer_ships) < total_ships:
coordinates = random.choice(grid)
if check_if_spot_is_free(coordinates):
computer_ships.append(coordinates)
一旦您收集了两个用户的船只 - 将它们存储在字典中以便日后访问：
game_board = {} # an empty dictionary
game_board['player'] = user_ships
game_board['computer'] = computer_ships
现在你拥有了所有的船只，你可以开始你的游戏循环。这个循环的条件是用户没有沉没对方的舰队。
您将在这里使用的方法很少。第一个是检查目标是否击中了对手的船只：
def check_if_ship_hit(target, user, game_board):
ships = game_board[user]
if target not in ships:
return False, game_board
else:
game_board[user][target] = None # Sunk!
return True, game_board
return False, game_board
第二个将检查用户是否丢失：
def user_lost(user, game_board):
ships = game_board[user]
# If the user has all Nones in his
# board, he loses
return sum(1 for i in ships if not i) == len(ships)
一旦我们拥有了这些，现在我们可以开始游戏了：
player_wins = False
computer_wins = False
while player_wins != True or computer_wins != True:
# First, its the player's turn:
target = input('Player, enter a coordinate for the enemy ship: ')
result, game_board = check_if_ship_hit(target, user='computer', game_board)
if result:
print('You scored a hit!')
else:
print('You miss!')
player_wins = user_lost('computer', game_board)
# Now, the computer's turn
target = random.choice(grid)
print('Computer selected a target!')
result, game_board = check_if_ship_hit(target, user='player', game_board)
if result:
print('You are hit!')
else:
print('Computer misses!')
computer_wins = user_lost('player', game_board)
