Python & Pygame: Impossible de sortir de l'état de pause

Question

Je suis nouveau sur Python et Pygame et j'ai programmé un petit jeu et essayé d'implémenter un menu pause. Alors que je peux accéder au menu pause, je ne peux pas m'en sortir. J'ai suivi un tutoriel par sentdex et j'ai un peu changé le code à mon goût. Je travaille avec Python-Idle mais je ne reçois aucun message d'erreur non plus alors je n'ai aucune idée de ce que je fais de mal.

black = (0,0,0)

starfighter_width = 160 

highscore = 0 

paused = False 

gameDisplay = pygame.display.set_mode((display_width,display_height)) 
pygame.display.set_caption('A bit Racey') 
clock = pygame.time.Clock()

asteroidImg = pygame.image.load('asteroid.png')

    if score > d['score']: 
     d['score'] = score 

    d.close()

Vous devez remplacer type avec key ici: if event.type == pygame.K_ESCAPE:.

Vous n'avez pas non plus besoin de la variable globale paused, restez simplement dans la fonction pause jusqu'à ce que l'utilisateur appuie sur Echap puis simplement return depuis la fonction.

import sys 
import pygame 


pygame.init() 

display = pygame.display.set_mode((800, 600)) 
clock = pygame.time.Clock() 


def pause(): 
    while True: 
     for event in pygame.event.get(): 
      if event.type == pygame.QUIT: 
       pygame.quit() 
       sys.exit() 
      elif event.type == pygame.KEYDOWN: 
       if event.key == pygame.K_ESCAPE: 
        return 

     pygame.draw.rect(display, (250, 0, 0), display.get_rect(), 3) 
     pygame.display.update() 
     clock.tick(60) 


def game_loop(): 
    x = 0 
    gameExit = False 

    while not gameExit: 
     for event in pygame.event.get(): 
      if event.type == pygame.QUIT: 
       gameExit = True 
      elif event.type == pygame.KEYDOWN: 
       if event.key == pygame.K_ESCAPE: 
        pause() 

     x += 1 
     display.fill((30, 30, 30)) 
     pygame.draw.rect(display, (0, 200, 250), (x, 200, 20, 20)) 

     pygame.display.update() 
     clock.tick(60) 


game_loop() 
pygame.quit()
