Keep Score

Lesson 13 of 40 in Coddy's Make Games with Pygame course.

Text in pygame is a picture of the words. A pygame.font.Font turns a string into a surface, and you draw that surface with screen.blit.

font = pygame.font.Font(None, 32)

text = font.render(f"Score: {score}", True, (240, 240, 240))
screen.blit(text, (10, 10))

Font(None, 32) is pygame's built-in font, 32 pixels high. Make it once, before the loop. render(text, True, color) draws the words; True smooths their edges. blit(surface, (x, y)) copies the picture onto the screen with its top left corner at (x, y).

Render the text inside the loop, after the fill. The score changes, and a picture made once keeps showing the old number.

Challenge

Easy

Before the loop, make font = pygame.font.Font(None, 32) and score = 0.
Add 1 to score when the basket catches a block.
After drawing the block, render f"Score: {score}" in (240, 240, 240) and blit it at (10, 10).

Try it yourself

import random
import pygame

pygame.init()
screen = pygame.display.set_mode((480, 360))
pygame.display.set_caption("Catch the Blocks")
clock = pygame.time.Clock()

basket = pygame.Rect(200, 330, 80, 16)
block = pygame.Rect(220, 0, 20, 20)

running = True
while running:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False

    keys = pygame.key.get_pressed()
    if keys[pygame.K_LEFT]:
        basket.x -= 8
    if keys[pygame.K_RIGHT]:
        basket.x += 8
    basket.clamp_ip(screen.get_rect())

    block.y += 3
    if block.top > 360:
        block.y = -20
        block.x = random.randint(0, 460)
    if block.colliderect(basket):
        block.y = -20
        block.x = random.randint(0, 460)

    screen.fill((30, 30, 46))
    pygame.draw.rect(screen, (80, 160, 255), basket)
    pygame.draw.rect(screen, (235, 80, 80), block)
    pygame.display.flip()
    clock.tick(60)

pygame.quit()
