Although I am fairly new to python, I have some experience with programming as a whole. I was watching a Tech With Tim tutorial on a python visualizer and everything was going well until I attempted to quit the window! for some reason, pygame.quit() does not work, even if I put sys.exit() or pygame.display.quit() after/before it. if someone has experienced this before, some help would be greatly appreciated as this is a big roadblock.

pygame.init()

BLACK = 0, 0, 0
WHITE = 255, 255, 255

TOP_PAD = 150
def __init__(self, width, height, lst):
self.width = width

self.window = pygame.display.set_mode((width, height))
pygame.display.set_caption("Sorting Algorithm Visualization")
self.set_list(lst)
def set_list(self, lst):
self.list = lst
self.min_val = min(lst)
self.max_val = max(lst)
self.block_width = round((self.width - self.SIDE_PAD) / len(lst))
self.block_height = round((self.height - self.TOP_PAD) / (self.max_val - self.min_val))
self.start_x = self.SIDE_PAD // 2
def generate_starting_list(n, min_val, max_val):
lst = []
for _ in range(n):
val = random.randint(min_val, max_val)
lst.append(val)
return lst

while run == True:
clock.tick(60)
pygame.display.update()
for event in pygame.event.get():
if event == pygame.QUIT:

pygame.display.quit()
pygame.quit()

CodePudding user response:
Your event check is incorrect because you're comparing an Event
object to pygame.QUIT
, which is an int
, so the comparison always fails and you'd never be able to quit the game.
You need to compare event.type == pygame.QUIT
like so:
while run == True:
clock.tick(60)
pygame.display.update()
for event in pygame.event.get():
# changed from 'event' to 'event.type'
if event.type == pygame.QUIT:
run = False
