我正在尝试通过制作基于 2D 平铺的平台游戏来学习 Python 和 Pygame。现在我被困在“基于瓷砖”的部分。这是我的代码：

import pygame, sys
from pygame.locals import *

#Just defining some variables
windowWidth = 640
windowHeight = 480
mapWidth = windowWidth // 32
mapHeight = windowHeight // 32
tilesize = 32
speed = [1, 1] #Array/List declaration
black = (0,0,0) #Tuple declaration

#intended to create a 2d list of subsurfaces    
def create_map():
    floor = pygame.image.load("rect_gray0.png")
    map = []
    for x in range(mapWidth):
        line = []
        map.append(line)
        for y in range(mapHeight):
            line.append(floor.subsurface((0,0,tilesize,tilesize)))

    return map


if __name__ == '__main__':

    pygame.init()
    print("Initializing")

    screen = pygame.display.set_mode((windowWidth, windowHeight))
    map = create_map()

    while 1:
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                sys.exit()

        screen.fill(black)

        for x in range(mapWidth):
            for y in range(mapHeight):
                #for each subsurface in the map, blit it to the screen.
                tile = map[x][y]
                screen.blit(tile, (x*tilesize, y*tilesize))

        screen.display.flip()

当我运行代码时，它给了我这个错误：

Traceback (most recent call last):
  File "C:\Users\dementeddr\workspace\TheWaterIsRising\src\default\RisingMain.py", line 59, in <module>
    screen.display.flip() 
AttributeError: 'pygame.Surface' object has no attribute 'display'

我用谷歌搜索了很多其他属性错误，但没有关于“显示”属性的信息。我究竟做错了什么？

错误消息告诉你你需要知道的一切：

Traceback (most recent call last):
  File "C:\Users\dementeddr\workspace\TheWaterIsRising\src\default\RisingMain.py", line 59, in <module>
    screen.display.flip()

以上部分显示了发生问题的确切代码行screen.display.flip()

AttributeError: 'pygame.Surface' object has no attribute 'display'

screen是 type pygame.Surface，它没有display属性，所以出了点问题。查看诸如http://www.pygame.org/docs/tut/intro/intro.html之类的教程表明您应该调用pygame.display.flip()。尝试替换该行，看看它是否运行。

祝你好运 ：）
