Re: pygame window not working

Click to Expand / Collapse Quote originally posted by ohblahitsme ...

Are you guys putting the code into the interactive python interpreter or are you creating a separate .py file. When I started my first pygame project, I tried putting it in the interpreter and got an Not Responding window. Of course I just started python and pygame so what do I know .

Why not try to run it from IDEs like Drpython, or Wing 101 and tell us the progress

I don't remember the full syntax, nor if it is actually what you are looking for but try
Python Syntax (Toggle Plain Text)
pygame.display.flip()
pygame.display.flip()

If I've understood correctly, flip() is specifically for double-buffered surfaces ... or more specifically, for changing buffers on surfaces for which you're taking advantage of SDL double buffering in the first place.

I've since found another tutorial that enlightened me re: the Not Responding window. It turns out the reason the window is 'not responding' is because our code is literally not responding to its event queue. Mouse clicks, mouse moves, key presses, and in fact lots of other random crud too, all pile up in the Windows Message Queue, and when Windows detects that a program isn't processing its messages (and thereby removing them from the queue - kind of like not reading your mail and letting it pile up in the mailbox), then Windows marks that window "Not Responding".

Python Syntax (Toggle Plain Text)
pygame.event.get()
# returns a list of events. I haven't read ahead enough to know how to
# deal with them individually, i.e. look for typed letters
# (as opposed to scanning the keyboard contstantly, hoping you don't miss one...)
# ... but I have determined that calling this function:
#     - clears the message queue
#     - makes the game window's 'Not Responding' tag go away
#     - allows all the drawn changes to show up
pygame.event.get()
# returns a list of events. I haven't read ahead enough to know how to
# deal with them individually, i.e. look for typed letters
# (as opposed to scanning the keyboard contstantly, hoping you don't miss one...)

Are you guys putting the code into the interactive python interpreter or are you creating a separate .py file. When I started my first pygame project, I tried putting it in the interpreter and got an Not Responding window. Of course I just started python and pygame so what do I know .

For a program run from a file, even if it doesn't do any event processing, the window's lifetime will be so short that it probably won't have a chance for any unprocessed events to pile up. So that way a program that is incorrect in that it does not check for events will still appear to work. I suspect that the reason I could see my circle drawn onscreen just before the window went away was that part of pygame.quit()'s job is to throw away any remaining events in the queue, and when that happens the drawing updates can go through as the last things to happen before the window dies.

Re: pygame window not werking

Try this from the interpreter (after creating a window)

Python Syntax (Toggle Plain Text)
while True:
 print pygame.event.wait()
while True:
 print pygame.event.wait()

to see all the events a window typically recieves.

i have discovered that if you add pygame.display.flip()...

Python Syntax (Toggle Plain Text)
import sys, pygame
from pygame.locals import *
 
pygame.init()
screen = pygame.display.set_mode((640,480))
pygame.display.flip()
import sys, pygame
from pygame.locals import *

pygame.init()
screen = pygame.display.set_mode((640,480))
pygame.display.flip()

the display will show the screen black like its supposed to , !but it will still will say not responding.if you add a while loop to the end it will work 100%%

Python Syntax (Toggle Plain Text)
 
import pygame,sys
from pygame.locals import*
 
screen = pygame.display.set_mode((640,480))
pygame.display.flip()
 
while 1:
    for event in pygame.event.get():
        if event.type==QUIT:
            pygame.quit()
            sys.exit()
import pygame,sys
from pygame.locals import*

screen = pygame.display.set_mode((640,480))
pygame.display.flip()

while 1:
    for event in pygame.event.get():
        if event.type==QUIT:
            pygame.quit()
            sys.exit()
