How they are used:

pygame.init() Initializes all Pygame modules

pygame.quit() Shuts down Pygame properly

pygame.display.set_mode() Creates the game window with specified dimensions

pygame.display.set_caption() Sets the window title

pygame.display.flip() Updates the entire display

pygame.time.get_ticks() Gets current time in milliseconds

pygame.time.set_timer() Creates a timer event

pygame.sprite.Sprite Base class for game objects

pygame.sprite.Group() Container to hold and manage multiple sprites

pygame.Surface Object for representing images

pygame.Rect Rectangle object for positions and collisions

pygame.mask.from_surface() Creates collision mask from surface

pygame.font.Font() Creates font object for text rendering

pygame.transform.rotate() Rotates surfaces

pygame.transform.scale() Resizes surfaces

pygame.event.get() Gets all pending events

pygame.QUIT Event type when window is closed

pygame.KEYDOWN Event type when key is pressed
