so i've changed the window color to a white color, unfortunately its not updating, it also returns an error

code:

import pygame

WIDTH, HEIGHT = 900, 500
WIN = pygame.display.set_mode((WIDTH,HEIGHT))
pygame.display = pygame.display.set_caption('PyGame Test')
WHITE = (255,255,255)
def main():
  run = True
  while run:
      for event in pygame.event.get():
          if event.type == pygame.QUIT:
              run = False

      WIN.fill(WHITE)
      pygame.display.update()
      
  pygame.quit()

if __name__ == '__main__':
  main()

what am i doing wrong?

CodePudding user response：

I believe you need to initialize the display module. Try pygame.init()

http://www.pygame.org/docs/ref/display.html#pygame.display.init

CodePudding user response：

In order to set the caption of the window, you need to type pygame.display.set_caption("Caption"). In your code, I see that you typed pygame.display = pygame.display.set_caption('PyGame Test'), which results in an AttributeError because pygame.display.set_caption() returns None, meaning you set pygame.display to None. So if you replace that line with pygame.display.set_caption('PyGame Test'), it will work.

Full code:

import pygame

WIDTH, HEIGHT = 900, 500

WIN = pygame.display.set_mode((WIDTH, HEIGHT))
pygame.display.set_caption('PyGame Test')
WHITE = (255, 255, 255)


def main():
    run = True
    while run:
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                run = False

        WIN.fill(WHITE)
        pygame.display.update()

    pygame.quit()


if __name__ == '__main__':
    main()
