Question

我正在python中创建战舰游戏，玩家可以在一台10x10板上随机放置船只的计算机上玩游戏。船只的安置工作正常，但船只偶尔会重叠。无论我做什么，它都不会停止与船只重叠。

这是代码： EDITED

ships = {'A': 5, 'B': 4, 'C': 3, 'S': 3, 'D': 2}
comp_board = []
for i in range(10):
comp_board.append([])
  for j in range(10):
   comp_board[i].append('.')

def print_computer_board(comp_board):
 for i in comp_board:
   print(' '.join(i))

def comp_place_ships(comp_board, ships):
  for key, value in ships.items():
    ship_not_placed = True
    while ship_not_placed:
     ori = random.randint(0,1)


    if ori == 0:
      x = random.randint(0,9-value)
      y = random.randint(0,9)
      placement = comp_board[x][y]
      if placement == '.':
        for ship in range(value):
          comp_board[x][y] = key
          comp_board[x+ship][y] = key
          ship_not_placed = False

    elif ori == 1:
      x = random.randint(0,9)
      y = random.randint(0,9-value)
      placement = comp_board[x][y]
      if placement == '.':
        for ship in range(value):
          comp_board[x][y] = key
          comp_board[x][y+ship] = key 
          ship_not_placed = False

    elif ori != 0 or 1 and placement != '.':
      print('Invalid choice, please try again.')
comp_place_ships(comp_board, ships)
print_computer_board(comp_board)

我尝试使用placement = comp_board [x + ship] [y]和placement_hort = comp_board [x] [y + ship]而不是placement = comp_board [x] [y]来检查展示位置是否有效，但是我收到一个错误：本地变量＆＃34; ship＆＃34;在转让前引用。

有人知道如何解决这个问题吗？我已经尝试了很长一段时间创建这个游戏，无论我做什么，我都会遇到一个又一个问题。

正如JeffUK所提到的，您似乎正在检查新船的末端是否与现有船相交，但没有检查中间部分是否相交。

因此，您需要编写两个循环：一个用于检查交叉点，另一个用于在网格上写出新的正方形。

any_intersections = False
if ori == 0:
  x = random.randint(0,9-value)
  y = random.randint(0,9)
  for z in range(y, y+value):
    if comp_board[x][z] != '.': any_intersections = True
  if not any_intersections:
    for ship in range(value):
      comp_board[x][y] = key
      comp_board[x+ship][y] = key

.... (ori = 1 is similar. I'll leave it as an exercise.)

if not any_intersections: print("Random allocation failed.")
return any_intersections

具有放置船只的功能似乎也更加灵活，例如

def place_ship(comp_board, ship_size):
  ori = random.randint(0,1)
  if ori == 0:
    x = random.randint(0,9-value)
    y = random.randint(0,9) #note: we could set a constant board_size = 10 and then range from 0 to board_size - 1 and board_size - 1 - value
    for z in range(y, y+value):
      if comp_board[x][z] != '.': return False
    for z in range(y, y+value): comp_board[x][z] = key
    return True

然后，可以按以下方式运行更通用的place_ships函数。我添加了一些错误检查，这是您不需要的，但是如果您想调整电路板的尺寸，也许会很有趣：

def place_ships(ship_list):
  for ship in ship_list:
    count = 0
    while not place_ship(comp_board, ship.size()):
      count += 1
      if count = 100:
        print("Bailing. Failed 100 times to place ship.")
        exit()
