嘿，我正在使用 Libtcod 使用 python 创建一个 roguelike 游戏。我有游戏生成随机房间的代码。它应该制作多个房间，直到一个交叉然后停止制作房间。问题是它总是只创建 1 个房间。这是孔代码：
import libtcodpy as libtcod;
SCREEN_WIDTH = 80;
SCREEN_HEIGHT = 50;
MAP_WIDTH = 80
MAP_HEIGHT = 45
ROOM_MAX_SIZE = 10
ROOM_MIN_SIZE = 6
MAX_ROOMS = 30
LIMIT_FPS = 20;
color_dark_wall = libtcod.Color(0, 0, 100)
color_dark_ground = libtcod.Color(50, 50, 150)
class Tile:
def __init__(self, blocked, block_sight = None):
self.blocked = blocked
if block_sight is None: block_sight = blocked
self.block_sight = block_sight
class Rect:
def __init__(self, x, y , w, h):
self.x1 = x
self.y1 = y
self.x2 = x + w
self.y2 = y + h
def center(self):
center_x = (self.x1 + self.x2) / 2
center_y = (self.y1 + self.y2) / 2
return (center_x, center_y)
def intersect(self, other):
return (self.x1 <= other.x2 and self.x2 >= other.x1 and
self.y1 <= other.y2 and self.y2 >= other.y1)
class Object:
def __init__(self, x, y, char, color):
self.x = x
self.y = y
self.char = char
self.color = color
def move(self, dx, dy):
if not map[self.x + dx][self.y + dy].blocked:
self.x += dx
self.y += dy
def draw(self):
libtcod.console_set_default_foreground(con, self.color)
libtcod.console_put_char(con, self.x, self.y, self.char, libtcod.BKGND_NONE)
def clear(self):
libtcod.console_put_char(con, self.x, self.y, ' ', libtcod.BKGND_NONE)
def create_room(room):
global map
for x in range(room.x1 + 1, room.x2):
for y in range(room.y1 + 1, room.y2):
map[x][y].blocked = False
map[x][y].block_sight = False
def create_h_tunnel(x1, x2, y):
global map
for x in range(min(x1, x2), max(x1, x2) + 1):
map[x][y].blocked = False

def create_v_tunnel(y1, y2, x):

for y in range(min(y1, y2), max(y1, y2) + 1):
map[x][y].blocked = False
map[x][y].block_sight = False
def make_map():
global map
map = [[ Tile(True)
for y in range(MAP_HEIGHT) ]
for x in range(MAP_WIDTH) ]
rooms = []
num_rooms = 0
for r in range(MAX_ROOMS):
w = libtcod.random_get_int(0, ROOM_MIN_SIZE, ROOM_MAX_SIZE)
h = libtcod.random_get_int(0, ROOM_MIN_SIZE, ROOM_MAX_SIZE)
x = libtcod.random_get_int(0, 0, MAP_WIDTH - w - 1)
y = libtcod.random_get_int(0, 0, MAP_HEIGHT - h -1)
new_room = Rect(x, y, w, h)
failed = False
for other_room in rooms:
if new_room.intersect(other_room):
failed = True
break
if not failed:
create_room(new_room)
(new_x, new_y) = new_room.center()
if num_rooms == 0:
player.x = new_x
player.y = new_y
else:
(prev_x, prev_y) = rooms[num_rooms-1].center()
if libtcod.random_get_int(0, 0, 1) == 1:
create_h_tunnel(prev_x, new_x, prev_y)
create_v_tunnel(prev_y, new_y, new_x)
else:
create_v_tunnel(prev_y, new_y, prev_x)
create_h_tunnel(prev_x, new_x, new_y)
rooms.append(new_room)
num_rooms += 1
def render_all():
global color_dark_wall, color_light_wall
global color_dark_ground, color_light_ground
for y in range(MAP_HEIGHT):
for x in range (MAP_WIDTH):
wall = map[x][y].block_sight
if wall:
libtcod.console_set_char_background(con, x, y, color_dark_wall, libtcod.BKGND_SET)
else:
libtcod.console_set_char_background(con, x, y, color_dark_ground, libtcod.BKGND_SET)
for object in objects:
object.draw()
libtcod.console_blit(con, 0, 0, SCREEN_WIDTH, SCREEN_HEIGHT, 0, 0, 0)
def handle_keys():
key = libtcod.console_check_for_keypress()
if key.vk == libtcod.KEY_ENTER and key.lalt:
libtcod.console_set_fullscreen(not libtcod.console_is_fullscreen())
elif key.vk == libtcod.KEY_ESCAPE:
return True #exit game
if libtcod.console_is_key_pressed(libtcod.KEY_UP):
player.move(0, -1)

libtcod.sys_set_fps(LIMIT_FPS);
con = libtcod.console_new(SCREEN_WIDTH, SCREEN_HEIGHT)
player = Object(SCREEN_WIDTH/2, SCREEN_HEIGHT/2, '@', libtcod.green)
npc = Object(SCREEN_WIDTH/2 - 5, SCREEN_HEIGHT/2, '@', libtcod.yellow)
objects = [npc, player]
#makes the map
make_map()
while not libtcod.console_is_window_closed():
render_all()
#libtcod.console_check_for_keypress()
libtcod.console_flush();
for object in objects:
object.clear()
exit = handle_keys()
if exit:
break
这是我怀疑问题所在的 make_map() 函数：
def make_map():
global map
map = [[ Tile(True)
for y in range(MAP_HEIGHT) ]
for x in range(MAP_WIDTH) ]
rooms = []
num_rooms = 0
for r in range(MAX_ROOMS):
w = libtcod.random_get_int(0, ROOM_MIN_SIZE, ROOM_MAX_SIZE)
h = libtcod.random_get_int(0, ROOM_MIN_SIZE, ROOM_MAX_SIZE)
x = libtcod.random_get_int(0, 0, MAP_WIDTH - w - 1)
y = libtcod.random_get_int(0, 0, MAP_HEIGHT - h -1)
new_room = Rect(x, y, w, h)
failed = False
for other_room in rooms:
if new_room.intersect(other_room):
failed = True
break
if not failed:
create_room(new_room)
(new_x, new_y) = new_room.center()
if num_rooms == 0:
player.x = new_x
player.y = new_y
else:
(prev_x, prev_y) = rooms[num_rooms-1].center()
if libtcod.random_get_int(0, 0, 1) == 1:
create_h_tunnel(prev_x, new_x, prev_y)
create_v_tunnel(prev_y, new_y, new_x)
else:
create_v_tunnel(prev_y, new_y, prev_x)
create_h_tunnel(prev_x, new_x, new_y)
rooms.append(new_room)
num_rooms += 1
程序创建房间后，将房间添加到列表中，但它不继续制造房间吗？还是创建的每个房间的大小相同（即使我传递了随机数）并且它创建了第一个房间然后停止？我不明白...
