Question

我一直试图让我的迷宫游戏背景成为我在电脑上的照片，这样我就可以让游戏看起来更好看。你可以看到我的班级的背景，但我卡住了，我不知道该怎么办，任何人都可以帮助它会很棒。

首先，我不确定你为什么要将背景变成精灵或类，这似乎是一种不必要的实现。

可以使用pygame.image.load（）加载背景并将其存储为表面并进行blitted，以便于显示。

一个简短的例子：

import pygame as py
py.init()

WINDOW_WIDTH = 640
WINDOW_HEIGHT = 360

screen = py.display.set_mode((WINDOW_WIDTH,WINDOW_HEIGHT))

background = py.image.load("image.png") ## Load the image file
background = py.transform.scale(background,(WINDOW_WIDTH,WINDOW_HEIGHT)) ## Make it the same size as the screen

clock = py.time.Clock()

done = False
while not done:
    for event in py.event.get():
        if event.type == py.QUIT:
            done = True
    screen.blit(background,(0,0)) ## Blit the background onto the screen first
    ## All other display stuff goes here
    py.display.flip()
    clock.tick(60)

py.quit()

如果您需要基于精灵和/或类的方法来显示背景，请询问，希望这会有所帮助。
