在pygame中创建一个随机门

Question

我正在尝试在pygame中创建一个随机门。我有一个这样的墙结构：

level = [
"WWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWW",
"W                                       W",
"W                                       W",
"W                                       W",
"W              WWWWWWWWW                W",
"               W       W                 ",
"W              W       W                W",
"W              W       W                W",
"W              W       W                W",
"W              WWWWWWWWW                W",
"                                         ",
"W                                       W",
"W                                       W",
"W                                       W",
"W                                       W",
"W                                       W",
"W                                       W",
"W                                       W",
"WWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWW",
]

图片如下所示：

我想在中心的矩形中创建一个随机门。一个人被固定在中心的矩形内。所以他必须试着走出随机门。

需要一些关于如何创建随机门的想法。任何建议都是受欢迎的。更好的实施方法也很受欢迎。

代码：

class Wall(object):

    def __init__(self, pos):
        walls.append(self)
        self.rect = pygame.Rect(pos[0], pos[1], 16, 16)

level = [
"WWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWW",
"W                                       W",
"W                                       W",
"W                                       W",
"W              WWWWWWWWW                W",
"               W       W                 ",
"W              W       W                W",
"W              W       W                W",
"W              W       W                W",
"W              WWWWWWWWW                W",
"                                         ",
"W                                       W",
"W                                       W",
"W                                       W",
"W                                       W",
"W                                       W",
"W                                       W",
"W                                       W",
"WWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWW",
]

x = y = 0
for row in level:
    for col in row:
        if col == "W":
            Wall((x, y))
        x += 16
    y += 16
    x = 0
for wall in walls:
        pygame.draw.rect(screen, (255, 255, 255), wall.rect)

我会将你的level更改为可以成为随机门的墙壁。我选择了＆＃34; R＆＃34;表示有可能成为随机门的墙壁。

level = [
"WWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWW",
"W                                       W",
"W                                       W",
"W                                       W",
"W              WRRRRRRRW                W",
"               R       R                 ",
"W              R       R                W",
"W              R       R                W",
"W              R       R                W",
"W              WRRRRRRRW                W",
"                                         ",
"W                                       W",
"W                                       W",
"W                                       W",
"W                                       W",
"W                                       W",
"W                                       W",
"W                                       W",
"WWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWW",
]

我还创建了一个名为RandomDoorCreator的函数，该函数接受level，并更改level以包含一个随机的＆＃34;门＆＃34; - 它实际上只是用＆＃39;替换随机位置。 ＆＃39;

import random
def RandomDoorCreator(level):
    locationsfordoor = []
    xpos = ypos = 0
    for element in level:
        ypos=0
        for letter in element:
            if letter == 'R':
                locationsfordoor.append([xpos,ypos]) #If it's a possible door location, add it to the list of possibilities
            ypos+=1
        xpos+=1
    doorlocation = random.choice(locationsfordoor) #Pick a random location from our list of locations
    newrow = list(level[doorlocation[0]]) #Create a list of strings for the row that we want to replace
    newrow[doorlocation[1]] = ' ' #Replace the correct value in the row with ' '
    del(level[doorlocation[0]]) #Delete the old row from the level
    level.insert(doorlocation[0],''.join(newrow)) #Add the new row to the level

之后，您必须编辑for循环以考虑新的＆＃34; R＆＃34; s：

RandomDoorCreator(level) #Create a random door BEFORE we create walls
x = y = 0
for row in level:
    for col in row:
        if col == "W" or col == "R": #Only row changed -- we just want to account for our new R values
            Wall((x, y))
        x += 16
    y += 16
    x = 0
for wall in walls:
        pygame.draw.rect(screen, (255, 255, 255), wall.rect)

我喜欢这种方法的原因是你可以创建完全不同的多个级别，并且仍然将它传递给函数而不需要任何额外的代码。它还使您可以在视觉上轻松选择可能的随机门位置，我认为这可以帮助制作游戏。
