So I am doing a simple thing, and have been following a tutorial on youtube. I have the ability to move the banshee (I used an image from Halo for my ship) using WASD, but I have to repetitively tap keys, whereas I want to be able to move it by holding down the keys. Here's the code;

Returns True if the pygame.displaypygame module to control the display window and screen module is. OPENGL flag, Pygame automatically handles setting. Pygame.display.quit Uninitialize the display module quit - None This will shut down the entire display module. Super bounce out free. This means any active displays will be closed. This will also be handled automatically when the program exits. 3.6: The QUIT Event and pygame.quit Function, 05, DISPLAYSURF = pygame.display.setmode(( 400, 300 )) Normally it doesn't really matter since Python closes it when the program exits Could someone help me out with closing a pygame window? I'm following along with a book I'm reading and one of the examples involves the module pygame. I'm new to programming, python and pygame. This is some code I wrote to draw random colored rectangles on an 800 x 600 canvas. It does what I expected it to do but becomes unresponsive if I click anywhere on the window. I am on a 64 bit windows 7 system running 32 bit python 2.7 with the appropriate pygame 1.9.1.

I have tried many different methods of doing this (On here and elsewhere), to little avail. Is there anything I can do here that doesn't need to rewrite a large section of code?

Thanks.

Why does the update method in Tkinter cause the window to freeze?

update() just processes events once. mainloop() (as the name implies) is a loop that continuously processes events. In your code you call root.update() only once, that's why your program becomes unresponsive or terminates. Put the call to root.update() in a while loop, and it will work as expected: while True:...

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:

When I append

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.

Could someone help me out with closing a pygame window?, QUIT: pygame.display.quit(), sys.exit() score += 1 #Check for arrow key presses, For now I just want to know what the code would be to close the window using​ The class method on_execute calls first the on_init method where pygame is intialized and the display mode is set, then the event loop is executed where pygame events are process and the current frame is rendered. Only if an pygame.QUIT event is catched the event loop is exited and the pygame.quit() is called to cleanup the pygame environment. Then also the applications ends.

if you want to make pygame close when window button x is pressed, put the code like this:

We put exit() after pygame.quit(), because pygame.quit() makes the system exit and exit() closes that window.

PyGame does not close when I press the close button, pygame.display.set_caption( 'Alien Invasion' ). # Set the I have to close the IDLE shell itself in order to close the window. I'm not sure why the We will: Create a Pygame window Stop the window from immediately disappearing Close the window in response to a quit event Change the title and background colour of the window

Not sure but try this Because you code runs fine on my system after I add pygame.quit() at the end

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.

Creating a Pygame window, Closing the window. We want our window to persist until the user chooses to closes it. To achieve this, we monitor user inputs (known as ' Most pygame tutorials seem to suggest exiting by calling pygame.quit () and then sys.exit ().

FrequentlyAskedQuestions, In IDLE why does the Pygame window not close correctly?¶. This is caused and if you also want to close the window on exceptions you might solve it like this​:. Pygame can only have a single display active at any time. Creating a new one with pygame.display.set_mode() will close the previous display. If precise control is needed over the pixel format or display resolutions, use the functions pygame.display.mode_ok(), pygame.display.list_modes(), and pygame.display.Info() to query information about the display.

Pygame Window Closing Automatically Start

Comments

• Try running the code from command prompt and see if the problem persist
• Have you looked at the relevant question on the pygame FAQ?
• what pygame version are you using?
• @Alfgaar To be honest, I don't remember. It was a while ago :)
• pygame.init() initializes all pygame modules (display, mixer, font, etc.) and pygame.quit() does the contrary, closes all modules. one can initalize a module per turn, if you want to use only display you do pygame.display.init(), no real need to call pygame.init... but, according to what you said, pygame.quit is faillling on closing the display module....
• Thank the lord, finally an answer that works! Been looking everywhere for an answer that wasn't just restating the pygame docs method. Personally this got rid of the window that was otherwise frozen, but the process still hung on pygame.quit(). I initialized only the display using @Alfgaar's method, and then removed pygame.quit() altogether to finally close it all the way.
• The except SystemExit works, but it still closes IDLE. Also, when I open command prompt it returns the error 'pygame.error:video system not initialized.' Any idea how to solve this? And by the way, thanks for the help.
• Well I cant figure out why is it closing the IDLE (not in my case). Also mind that it may be the problem that you are replacing your code pygame.QUIT with pygame.quit(). pygame.quit() is a function that closes pygame (python still running) While pygame.QUIT just checks if pygame is running or not.
• I put pygame.quit() function after the while loop to make sure that pygame is not running after the while loop. do not use it while checking ( if-else statements).
