Pygame screen freezes when I close it

Question

The code loads up a pygame screen window, but when I click the X to close it, it becomes unresponsive. I\'m running on a 64-bit system, using a 32-bit python and 32-bit pygame.<

Answer 1

I'd recommend the following code. First, it includes Clock so your program doesn't eat the CPU doing nothing but polling for events. Second, it calls pygame.quit() which prevents the program from freezing when running under IDLE on windows.

# Sample Python/Pygame Programs

import pygame

# Define some colors
black    = (   0,   0,   0)
white    = ( 255, 255, 255)
green    = (   0, 255,   0)
red      = ( 255,   0,   0)

pygame.init()

# Set the height and width of the screen
size=[700,500]
screen=pygame.display.set_mode(size)

pygame.display.set_caption("My Game")

#Loop until the user clicks the close button.
done=False

# Used to manage how fast the screen updates
clock=pygame.time.Clock()

# -------- Main Program Loop -----------
while done==False:
    for event in pygame.event.get(): # User did something
        if event.type == pygame.QUIT: # If user clicked close
            done=True # Flag that we are done so we exit this loop

    # Set the screen background
    screen.fill(black)

    # Limit to 20 frames per second
    clock.tick(20)

    # Go ahead and update the screen with what we've drawn.
    pygame.display.flip()

# Be IDLE friendly. If you forget this line, the program will 'hang'
# on exit.
pygame.quit ()
