Pygame error: display surface quit: Why?
提问by Devo
Can anyone tell me why my app quits with:
谁能告诉我为什么我的应用程序退出：
pygame error: display Surface quit.
pygame 错误：显示 Surface 退出。
回答by Maciej Mi?sik
I had similar problem and discovered that Surface objects don't like to be deepcopied. When I used copy.deepcopy() on such object and then accessed the copy, I got that strange error message (without calling pygame.quit()). Maybe you experience similar behavior?
我遇到了类似的问题，发现 Surface 对象不喜欢被深度复制。当我在这样的对象上使用 copy.deepcopy() 然后访问副本时，我收到了那个奇怪的错误消息（没有调用 pygame.quit()）。也许你遇到过类似的行为？

I had a similar problem in a very simple piece of code:
我在一段非常简单的代码中遇到了类似的问题：
import sys, pygame
pygame.init()
size = width, height = 640, 480
speed = [2, 2]
black = 0, 0, 0
screen = pygame.display.set_mode(size)
ball = pygame.image.load("Golfball.png")
ballrect = ball.get_rect()
while 1:
event = pygame.event.poll()
if event.type == pygame.QUIT:
pygame.quit()
ballrect = ballrect.move(speed)
if ballrect.left < 0 or ballrect.right > width:
speed[0] = -speed[0]
if ballrect.top < 0 or ballrect.bottom > height:
speed[1] = -speed[1]
screen.fill(black)
screen.blit(ball, ballrect)
pygame.display.flip()
pygame.time.delay(5)
Error message was:
错误信息是：
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "bounce.py", line 22, in <module>
screen.fill(black)
pygame.error: display Surface quit
So I put
所以我把
import pdb
at the top after
在顶部之后
pygame.init()
and used
并使用
pdb.set_trace()
afterthe line with
在行之后
pygame.quit()
Now I ran the program, clicked to close the window and was actually a bit surprised to see that I fell into the debugger (after all, I expected the quit to completely take me out immediately). So I concluded that the quitdoesn't actually stop everything at that point. Looked like the program was continuing beyond the quit, was reaching
现在我运行程序，点击关闭窗口，看到我掉进调试器实际上有点惊讶（毕竟我预计退出会立即将我完全带出）。所以我得出结论，退出实际上并没有在那时停止一切。看起来程序在退出之后还在继续，正在到达
screen.fill(black)
and this was causing the problem. So I added
这导致了问题。所以我加了
break
after the
之后
pygame.quit()
and all works happily now.
现在一切都很愉快。
[ Added later: It occurs to me now that
[后来补充：我现在想到的是
pygame.quit()
is quitting the module, and not the program that is running, so you need the breakto get out of this simple program. ]
正在退出模块，而不是正在运行的程序，因此您需要休息一下才能退出这个简单的程序。]
Just for the record, this means the good version is
只是为了记录，这意味着好的版本是
import sys, pygame
pygame.init()
size = width, height = 640, 480
speed = [2, 2]
black = 0, 0, 0
screen = pygame.display.set_mode(size)
ball = pygame.image.load("Golfball.png")
ballrect = ball.get_rect()
while 1:
event = pygame.event.poll()
if event.type == pygame.QUIT:
pygame.quit()
break
ballrect = ballrect.move(speed)
if ballrect.left < 0 or ballrect.right > width:
speed[0] = -speed[0]
if ballrect.top < 0 or ballrect.bottom > height:
speed[1] = -speed[1]
screen.fill(black)
screen.blit(ball, ballrect)
pygame.display.flip()
pygame.time.delay(5)

import pygame, sys
running = True
while running:
for event in pygame.event.get():
if event.type == pygame.QUIT:
pygame.quit() # quit the screen
running = False
sys.exit()
call sys.exit() after pygame.quit() to stop the program so you can not change the surface after you have quit pygame and not get the error
在 pygame.quit() 之后调用 sys.exit() 以停止程序，因此在退出 pygame 后您无法更改表面并且不会收到错误

I had this problem too, but got it from another origin.
我也有这个问题，但它是从另一个来源得到的。
I had a class defined like this:
我有一个这样定义的类：
class PauseMenu(pygame.Surface)
i got the error when forgetting to initialize the pygame.Surface and trying to blit it, making pygame.screen crash and gave me this error.
我在忘记初始化 pygame.Surface 并尝试对其进行 blit 时遇到错误，导致 pygame.screen 崩溃并给了我这个错误。
so i just added this obviously
所以我只是明显地添加了这个
pygame.Surface.__init__(self, (width, height))

pygame.error: display Surface quit 这意味着什么？，我无法修复
This means a call was made to pygame.display.quit() or pygame.quit(). If you try to do anything to the display surface after quit you will get this error.
这意味着调用了 pygame.display.quit() 或 pygame.quit()。如果您在退出后尝试对显示表面执行任何操作，您将收到此错误。

I too had this problem, and similar to Maciej Mi?sik's answer mine had to do with copy.deepcopy()-ing an image.
我也有这个问题，类似于 Maciej Mi?sik 的回答，我的回答与 copy.deepcopy() 图像有关。
I had:
我有：
import copy,pygame,sys
from pygame.locals import *
EMPTY_IMG= pygame.image.load('C:super/fancy/file/path/transparent.png')
held_image=copy.deepcopy(EMPTY_IMG)
my_rect=held_image.get_rect()
my_rect.center = (50,50)
screen.blit(held_image,my_rect)
And I got the same error.
我得到了同样的错误。
I simply changed the copy.deepcopy(EMPTY_IMG) to just EMPTY_IMG.
我只是将 copy.deepcopy(EMPTY_IMG) 更改为 EMPTY_IMG。
import copy,pygame,sys
from pygame.locals import *
EMPTY_IMG= pygame.image.load('C:super/fancy/file/path/transparent.png')
held_image=EMPTY_IMG
my_rect=held_image.get_rect()
my_rect.center = (50,50)
screen.blit(held_image,my_rect)
Then it all worked fine.
然后一切正常。

Replace if event.type == pygame.quit():by if event.type == pygame.QUIT:
替换if event.type == pygame.quit():为if event.type == pygame.QUIT:
回答by Pasquale Palombo
Make sure if you write pygame.QUIT:and not pygame.quit():I know it sounds weird, but I had the same problem.
确保你写pygame.QUIT:而不是pygame.quit():我知道这听起来很奇怪，但我有同样的问题。
