如何添加一个分数文本列表，该列表每次单击Cookie精灵时加1？ （蟒蛇）

Question

Game code deals with classes Cookie and Shop. How do I make it so that I have a text box which says {Cookie Number} Cookies? Is there a command that says if event.click then cookie +1?

Inside of the game_loop is a simple text box that just says "some cookie number, with the word cookies at the end. I think I would have to create a list but I am not sure how to do that. Would I use {} ? Also, thank you to everyone for your help.

Answer 1

In the event loop, check if the user presses a mousebutton, then see if the cookie.rect collides with the event.pos (or use pg.mouse.get_pos() ), and if they collide, increment a score variable:

elif event.type == pg.MOUSEBUTTONDOWN:
    # Use the collidepoint method of this `pygame.Rect`.
    if cookie.rect.collidepoint(event.pos):
        score += 1
        print(score)

To blit the text onto the screen, you need to put the score into a string with the help of the .format method: '{} Cookies'.format(score) . Then pass it to my_font.render and blit the returned surface.

text_surface = my_font.render('{} Cookies'.format(score), True, BROWN)
screen.blit(text_surface, (30, 30))

Also, you shouldn't create and fill the all_sprites group inside of the while loop. Here's the updated game_loop function:

def game_loop():
    pg.init()

    my_font = pg.font.SysFont("Comic Sans MS", 30)
    cookie = Cookie()
    shop = Shop()
    all_sprites = pg.sprite.Group()
    all_sprites.add(cookie, shop)
    score = 0

    running = True
    while running:
        for event in pg.event.get():
            if event.type == pg.QUIT:
                running = False
            elif event.type == pg.MOUSEBUTTONDOWN:
                if cookie.rect.collidepoint(event.pos):
                    score += 1
                    print(score)

        all_sprites.update()

        screen.fill(BGCOLOR)
        all_sprites.draw(screen)
        screen.blit(text_surface, (175, 100))
        text_surface = my_font.render('{} Cookies'.format(score), True, BROWN)
        screen.blit(text_surface, (30, 30))
        pg.display.flip()

        CLOCK.tick(FPS)

    pg.quit()
    sys.exit()  # import sys at the top of the file.
