I have made a python program that uses Pygame. For some reason, I can't close the window when pressing the red cross. I tried using Command+Q but it doesn't work as well. I have to quit idle (my python interpreter) to close the window. Is there any other way to make the window close by pressing the red 'x' at the top right-hand corner?
My code:
import pygame
import sys
from pygame.locals import *
pygame.init()
screen = pygame.display.set_mode((800,800))
while 1:
pygame.display.update()
for event in pygame.event.get():
if event.type == QUIT:
pygame.quit()
sys.exit()
A pygame window can be closed properly if you use a different python interpreter. Try using pycharm, you can close pygame windows using pycharm.
You should just force quit the window or run another program to close the window. When you run a different program, the window should close.
Try this:
import pygame, sys
from pygame.locals import *
pygame.init()
screen = pygame.display.set_mode((800,800))
while True:
pygame.display.update()
for event in pygame.event.get():
if event.type == pygame.QUIT:
pygame.quit()
sys.exit()

I just spent a fair amount of time finding a 64-bit installation of pygame to use with python 3.3, (here) and now am trying to make a window. However, although the window opens up fine it does not close when it hit the x button. In fact, I have to close IDLE to close the window. I am running a 64 bit version of Win 7. Here is my code:
import pygame
import time
(width, height) = (300, 200)
screen = pygame.display.set_mode((width, height))
pygame.display.flip()
pygame.display.set_caption("Hello World")
running = True
while running:
for event in pygame.event.get():
if event.type == pygame.QUIT:
running = False
When I append
time.sleep(5)
pygame.quit()
It still doesn't close. My only guess would be that pygame.quit might go inside one of the loops, but even if that were resolved I would greatly prefer being able to close the window when I want to.
Most pygame tutorials seem to suggest exiting by calling pygame.quit() and then sys.exit(). I have personally run into problems (was on a unix system though) where this still did not close the window properly. The solution was to add pygame.display.quit() specifically before pygame.quit(). That should not be necessary as far as I can tell, and I'm afraid I don't know why that solved the issue but it did.
if you want to make pygame close when window button x is pressed, put the code like this:
from sys import exit
while True:
for event in pygame.event.get():
if event.type == pygame.QUIT:
pygame.quit()
exit()
We put exit() after pygame.quit(), because pygame.quit() makes the system exit and exit() closes that window.
Not sure but try this Because you code runs fine on my system after I add pygame.quit() at the end
import pygame
import time
(width, height) = (300, 200)
screen = pygame.display.set_mode((width, height))
pygame.display.flip()
pygame.display.set_caption("Hello World")
running = True
try:
while running:
for event in pygame.event.get():
if event.type == pygame.QUIT:
running = False
pygame.quit()
except SystemExit:
pygame.quit()
Its perhaps because as Idle is made on Tkinter and thus Tkinter and Pygame main loop do not have a mutual understanding.
Your code will run very well on command prompt though.
This was the final code that worked for me on OSX whilst keeping the kernel alive on Jupyter. EDIT - it does still crash the kernel sometimes :-(
running = True
while running:
for event in pygame.event.get():
if event.type == pygame.QUIT:
running = False
pygame.display.quit()
pygame.quit()
exit()
Also needed to downgrade ipython to get rid of some magic alias warning messages using:
conda install ipython=7.2.0
apparently that issue is due to be fixed in ipython 7.6.0
Suffered the same issues on Python 3.7.4 while running it from in IDE (Spyder 3.3.6). In my case the pygame.quit() would not completely close the program.
Nonetheless, adding quit() or exit() did the trick for me!
Add this at the top:
import sys
Add this where you need to quit:
if event.type == pygame.QUIT:
pygame.quit()
sys.exit()
try using the following command:
sys.exit(0)
notice: You will need to import the sys library in order to use it.
The IDE interferes with how pygame runs the code. Try to run it from the commandline or the terminal. The problem should disappear.
To answer the original question: You must call pygame.quit() after breaking the main loop. One elegant solution goes as follows:
def run():
pygame.init()
while True:
# ...
for event in pygame.event.get():
# Handle other events
if event.type == pygame.QUIT:
return pygame.quit()
I just want to know the difference between .quit and .QUIT in pygame. I've tested both but I continue to not understand how they work.
QUIT is the enumerator constant for an event type (see event module). The quit event occurs when the pygame window is closed:
for event in pygame.event.get():
if event.type == pygame.QUIT:
# [...]
quit() is a function which uninitialize all pygame modules. This function should be called at the end of the applicaiition:
# initialize all imported pygame modules
pygame.init()
# application loop
while True:
# [...]
# uninitialize all pygame modules
pygame.quit()
The .QUIT in pygame is used to check if you pressed the cross button on the window which is a pygame event. If you have to quit a window you should press the cross button most of the times.
Here is a example of an image for with the cross button on a window
So when you press the cross arrow button on the window it quits the window so when you press the cross button on a pygame window it is stored in a event named pygame.QUIT.
pygame.quit() uninstializez all of pygame's modules i am not sure but after you say nthe line pygame.quit() you wont be able to use most of or all pygame function
I have a simple Pygame program:
#!/usr/bin/env python
import pygame
from pygame.locals import *
pygame.init()
win = pygame.display.set_mode((400,400))
pygame.display.set_caption("My first game")
But every time I try to run it, I get this:
pygame 2.0.0 (SDL 2.0.12, python 3.8.3)
Hello from the pygame community. https://www.pygame.org/contribute.html
And then nothing happens.
Why I can't run this program?
Your application works well. However, you haven't implemented an application loop:
import pygame
from pygame.locals import *
pygame.init()
win = pygame.display.set_mode((400,400))
pygame.display.set_caption("My first game")
clock = pygame.time.Clock()
run = True
while run:
# handle events
for event in pygame.event.get():
if event.type == pygame.QUIT:
run = False
# update game objects
# [...]
# clear display
win.fill((0, 0, 0))
# draw game objects
# [...]
# update display
pygame.display.flip()
# limit frames per second
clock.tick(60)
pygame.quit()
The typical PyGame application loop has to:
handle the events by calling either pygame.event.pump() or pygame.event.get().
update the game states and positions of objects dependent on the input events and time (respectively frames)
clear the entire display or draw the background
draw the entire scene (blit all the objects)
update the display by calling either pygame.display.update() or pygame.display.flip()
limit frames per second to limit CPU usage with pygame.time.Clock.tick

This is interesting. Computer read your program line by line[python]. When all the line are interpreted, the program closed. To solve this problem you need to add a while loop to make sure the program will continue until you close the program.
import pygame,sys
from pygame.locals import *
pygame.init()
pygame.display.set_caption("My first game")
win = pygame.display.set_mode((400,400))
#game loop keeps the game running until you exit the game.
game_running=True
while game_running:
for event in pygame.event.get():
if event.type==QUIT:
pygame.quit()
sys.exit()
win.fill((0, 250, 154)) #Fill the pygame window with specific color. You can use hex or rgb color
pygame.display.update() #Refresh the pygame window

update the game states and positions of objects dependent on the input events and time (respectively frames)
clear the entire display or draw the background

I'm slowly trying to get to know pygame and write my first game in it and honestly, I didn't expect problems so early. So far I've only set a display, that is supposed to be there indefinitely (I just wanted to try it out):
import pygame
pygame.init()
(width, height) = (1000, 700)
screen = pygame.display.set_mode((width, height))
while True:
pygame.display.flip()
But when the window appears it says it's "not responding". I tried deleting the loop so that display would just blink once and vanish, because programm would die immiedately after it's created, but I get the same "not responding" window. I'm using pygame 1.9.2 and python 3.5. I wonder if the trouble may be because of anaconda - the window is opened as subcart for anaconda by default.
Edit: So far I discovered that when I open it not from spyder, but just click on a file it works just fine. Is there any way to make it work by simple run and compile while in spyder or it's just how it's supposed to work?
Add this to your loop. For me the only time it isnt responding is when I click the X and this could be to do with the fact that pygame doesn't know what to do when that happens.
import sys
for evt in pygame.event.get():
if evt.type == pygame.QUIT:
pygame.quit()
sys.exit()
#Try This
import pygame
(width, height) = (1000, 700)
screen=pygame.display.set_mode((width, height))
pygame.display.update()
while True:
for event in pygame.event.get():``
if event.type == pygame.QUIT:
pygame.quit()
quit()
