我無法用字典解決的pythonIndexError-有解無憂

我有一個簡單的問題，為此我需要一雙新的眼睛。我有一本適合我的世界的字典：

world = {}

以及一個基于二維陣列填充該字典中房間的函式：

def makeRoomsForLevel():

  counter = 1

  for r in range(len(rooms)):
    for c in range(len(rooms)):
      if rooms[c][r] == 1:
        world[f"room{counter}"] = Room(
          f"room{counter}",
          "",
          {},
          False,
          None,
          False,
          None,
          False,
          None,
          True,
          (r, c)
        )
        counter  = 1

還有另一個我正在努力尋找房間出口的功能：

def findExits():
  counter = 1;

  for x in range(len(world)):
    if rooms[world[f"room{counter}"]].coords[0]   1 == 1:
      pass

我在填寫 if 陳述句之前嘗試運行它，它給了我這個錯誤：

IndexError: only integers, slices (':'), ellipsis ('...'), numpy.newaxis ('None') and integer or boolean arrays are valid indicies

我有點知道這意味著什么，但它事先沒有給我帶來任何問題。這是房間等級：

class Room():
  def __init__(self, name, description, exits, hasWeapon, weapon, hasItem, item, hasEnemy, enemy, isFirstVisit, coords):
    self.name = name
    self.description = description
    self.exits = exits
    self.hasWeapon = hasWeapon
    self.weapon = weapon
    self.hasItem = hasItem
    self.item = item
    self.hasEnemy = hasEnemy
    self.enemy = enemy
    self.isFirstVisit = isFirstVisit
    self.coords = coords

這是“房間”的含義：

rooms = np.zeros((11, 11))

這是完整的生成代碼：

rooms = np.zeros((11, 11))
maxRooms = 7
possibleNextRoom = []
world = {}

def startLevel():
  for r in range(len(rooms[0])):
    for c in range(len(rooms[1])):
      rooms[r][c] = 0

  possibleNextRoom.clear()

  halfHeight = int(len(rooms[1]) / 2)
  halfWidth = int(len(rooms[0]) / 2)
  rooms[halfWidth][halfHeight] = 1

def resetLevel():
  for r in range(len(rooms[0])):
    for c in range(len(rooms[1])):
      rooms[r][c] = 0
  
  possibleNextRoom.clear()

def countRooms():

  roomCount = 0

  for r in range(len(rooms)):
    for c in range(len(rooms)):
      if rooms[r][c] == 1:
        roomCount  = 1

  return roomCount

def findPossibleRooms():

  for r in range(len(rooms) - 1):
    for c in range(len(rooms) - 1):
      if rooms[r][c] == 1:
        if rooms[r][c 1] != 1:
          possibleNextRoom.append((r, c 1))
        if rooms[r][c-1] != 1:
          possibleNextRoom.append((r, c-1))
        if rooms[r-1][c] != 1:
          possibleNextRoom.append((r-1, c))
        if rooms[r 1][c] != 1:
          possibleNextRoom.append((r 1, c))

def addRoom():
  x = random.randrange(0, len(possibleNextRoom))

  rooms[possibleNextRoom[x][0]][possibleNextRoom[x][1]] = 1
  possibleNextRoom.pop(x)

def generateLevel():

  global x, possibleNextRoom

  startLevel()

  while countRooms() < maxRooms:
    countRooms()
    findPossibleRooms()
    addRoom()

def makeRoomsForLevel():

  counter = 1

  for r in range(len(rooms)):
    for c in range(len(rooms)):
      if rooms[c][r] == 1:
        world[f"room{counter}"] = Room(
          f"room{counter}",
          "",
          {},
          False,
          None,
          False,
          None,
          False,
          None,
          True,
          (r, c)
        )
        counter  = 1

def findExits():
  counter = 1;

  for x in range(len(world)):
    if rooms[world[f"room{counter}"].coords[0]]   1 == 1:
      pass

def fillRooms():
  counter = 1

  for x in range(len(world)):
    x = random.randrange(1, 2)

    if x == 1:
      world[f"room{counter}"].hasItem = True

    x = random.randrange(1, 10)

    if x == 1:
      world[f"room{counter}"].hasWeapon = True

    x = random.randrange(1, 4)

    if x == 1:
      world[f"room{counter}"].hasEnemy = True

    counter  = 1

這是整個代碼：

uj5u.com熱心網友回復：

IIUC，你需要這樣的東西：

#find the name of the room given the coordinates
def findRoom(x, y):
    for i in range(len(world)):
        if world[f"room{i 1}"].coords == (x, y):
            return f"room{i 1}"
    return None

def findExits():
    for i in range(len(world)):
        x, y = world[f"room{i 1}"].coords
        exits = dict()
        
        #east
        if rooms[x, y 1] == 1:
            exits["E"] = findRoom(x, y 1)
        
        #south
        if rooms[x 1, y] == 1:
            exits["S"] = findRoom(x 1, y)
        
        #west
        if rooms[x, y-1] == 1:
            exits["W"] = findRoom(x, y-1)
        
        #north
        if rooms[x-1, y] == 1:
            exits["N"] = findRoom(x-1, y)
            
        world[f"room{i 1}"].exits = exits

運行上述后，退出room1看起來像：

>>> world["room1"].exits
{'E': 'room2', 'S': 'room4'}

您可以使用上述結構，根據需要更改鍵和值。
