Python : pygame.quit() not working on Mac M1?-CodePudding

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.

import pygame
import random 

pygame.init()

class DrawInformation:
    BLACK = 0, 0, 0
    WHITE = 255, 255, 255
    GREEN = 0, 255, 0
    RED = 255, 0, 0
    GREY = 128, 128, 128
    BACKGROUND_COLOR = WHITE

    SIDE_PAD = 100
    TOP_PAD = 150

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

    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


def main():
    run = True
    clock = pygame.time.Clock()

    n = 50
    min_val = 0
    max_val = 100

    lst = generate_starting_list(n, min_val, max_val)
    draw_info = DrawInformation(800, 600, lst)

    while run == True:
        clock.tick(60)

        pygame.display.update()

        for event in pygame.event.get():
            if event == pygame.QUIT:
                run = False

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


if __name__ == "__main__":
     main()

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
