[PyGame] drawing images onto pygame window

[nilamo]

self.stars is a SpriteGroup that you draw each frame. It looks like the only place you add items to that sprite group is in StarrySky.create_grid()... but I don't see anywhere where that function gets called. Should that be included in the __init__ method?

Something like:

    def __init__(self):
        """Initialise the game and create game resources."""
        pygame.init() # initialise the background settings 
        # which the game needs to work properly
        self.settings = Settings()
 
        self.screen = pygame.display.set_mode((0,0), pygame.FULLSCREEN)
        # tells pygame to figure out a window size to fill the screen
        self.settings.screen_width = self.screen.get_rect().width
        self.settings.screen_height = self.screen.get_rect().height
        # updates the screen settings after fullscreen has been created
        pygame.display.set_caption("Starry Sky")
 
        self.star = Star(self)
        self.stars = pygame.sprite.Group()
        self.create_grid()
