PyGame Window Creation
Creating the Main Window
With main_display = pygame.display.set_mode((WIDTH, HEIGHT)), we summon the primary canvas of our adventure, setting it to the dimensions we've previously etched into our constants, WIDTH and HEIGHT. This magic incantation, courtesy of pygame.display.set_mode, breathes life into our game window, preparing a stage for the epic tales to unfold.
Setting the Stage with Background
By invoking bg = pygame.transform.scale(pygame.image.load('space.png'), (WIDTH, HEIGHT)), we delve into the art of scenery. This spell fetches an image from the depths of our files, space.png, transforming it to fit the grand scale of our window. The result is bg, a surface mirroring the dimensions of our game window, ready to serve as the backdrop for our saga.
Positioning the Horizon with bg_x1 and bg_x2
With bg_x1 = 0, we anchor our background to the game's left edge, setting the stage for our story's beginning. Meanwhile, bg_x2 = bg.get_width() casts a second instance of our background just off the right edge, preparing for a seamless scroll. This technique lays the groundwork for an eternal canvas, where one scene fluidly gives way to the next.
Note
There is also get_height() method on par with get_width().
Animating the Scene with bg_move
Through bg_move = 1, we dictate the rhythm of our background's journey across the screen, a single pixel per frame, breathing motion into our static universe. This subtle shift creates an illusion of movement, propelling our game into a realm of dynamism, perfect for space odysseys or high-speed chases.
As the narrative progresses, bg_x1, bg_x2, and bg_move become the conductors of our background's endless scroll, infusing our game with the essence of motion and bringing the illusion of life to our digital cosmos.
Tarefa
- Define the main game window: use
main_display =pygame.display.set_mode((WIDTH, HEIGHT))to create the main window for the game with the predefined WIDTH and HEIGHT dimensions; - Load and scale the background image: with
bg =pygame.transform.scale(pygame.image.load('space.png'), (WIDTH, HEIGHT)), load the 'space.png' image, scaling it to fit the game window; - Initialize background positions: set
bg_x1 = 0to start the background at the left edge of the window, and usebg_x2 = bg.get_width()to position a second background image right after the first, preparing for a continuous scrolling effect; - Set background movement speed: assign
bg_move = 1to control how fast the background images move across the screen, creating the illusion of motion in the game.
