Pygame 错误:视频系统未初始化 [英] Pygame error : video system not initialized

问题描述

import sys,pygame
pygame.init()

size = width , height = 600,400 
screen = pygame.display.set_mode(size)

tux = pygame.image.load("tux.png")

screen.blit(tux,(200,200))
screen.blit(tux,(0,0))
pygame.display.flip()

while 1:
ev = pygame.event.poll() 
if ev.type == pygame.QUIT:
    pygame.quit()

上面的代码显示了这个错误

The above code is showing this error

---------------------------------------------------------------------------

    169             else:
    170                 filename = fname
--> 171             exec compile(scripttext, filename, 'exec') in glob, loc
    172     else:
    173         def execfile(fname, *where):

C:\Users\digi.abhshk\Desktop\tux.py in <module>()
    11 pygame.display.flip()
    12 while 1:
--->13         ev = pygame.event.poll()
    14         if ev.type == pygame.QUIT:
    15             pygame.quit()

error: video system not initialized

我对 pygame 很陌生，这是什么错误以及如何删除它?PS:tux 是我在这个文件中使用的 png 图像

I am very new to pygame , what is this error and how to remove it ? PS: tux is the png image i am using in this file

推荐答案

在调用 pygame.quit() 后，您不会中断 while 循环.

You don't break your while loop after calling pygame.quit().

只要使用

while 1:
    ev = pygame.event.poll() 
    if ev.type == pygame.QUIT:
        break
pygame.quit()

或者类似的东西.否则，您将在循环的下一次迭代中调用 pygame.event.poll() after pygame.quit() ，这将导致你的错误.

or something like that. Otherwise, you'll call pygame.event.poll() after pygame.quit() on the next iteration of the loop, which will lead to your error.
