PyGame - How to get an image in the center of the screen

Question

# MENU
def gameMenu():
intro = True
while(intro == True):
    win.fill((0,0,0))
    iPATH = f\"{PATH}/assets/textures/titleScreen/buttons\"
    win.blit(pygame.image.loa         


        

Answer 1

First of all, by convention, you should name your screen Surface simply screen.

Then, you're loading the image files over and over again in the while loop. Just load it once.

It's also good to (almost) always use convert after loading an image so the Surface will have the same pixel format as the screen.

Finally, in pygame, you should use the Rect class for (almost) everything related to drawing/positioning.

Here you can see how easy it is to center something using the Rect class. I also reordered your loop to follow the classic input/update/draw convention and removed the second image for brevity:

def gameMenu():

    iPATH = f"{PATH}/assets/textures/titleScreen/buttons"
    logo = pygame.image.load(os.path.join(f"{iPATH}/Logo.png")).convert()

    logo_rect = logo.get_rect(center = screen.get_rect().center)

    while True:

        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                return

        keys = pygame.key.get_pressed()
        if keys[selectButton]:
            print("clicked z")
            break
        elif keys[backButton]:
            print("clicked x")

        screen.fill((0,0,0))
        screen.blit(logo, logo_rect)
        pygame.display.update()
