python - 在pygame中创建一个随机门

Question

我正在尝试在 pygame 中创建一扇随机门。我创建了一个这样的墙结构:

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",
]

图像如下所示:

我想在中心的矩形中创建一扇随机门。一个人被固定在中心的矩形内。所以他必须想方设法走出这扇随机门。

需要一些关于如何创建随机门的想法。欢迎任何建议。也欢迎更好的实现方法。

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)

我会将您的级别更改为表示可以变成随机门的墙壁的内容。我选择“R”来表示有可能是随机门的墙壁。

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，它接受 level，并更改 level 以包含随机“门” -- 它实际上只是用“”替换随机位置。

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

然后，您必须编辑 for 循环以考虑新的“R”:

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，您可以创建多个完全不同的级别，并且仍然将其传递给函数，而无需任何额外的代码。它还使得在视觉上更容易选择可能的随机门位置，我认为这有助于游戏的制作。
