Lives

Lesson 14 of 40 in Coddy's Make Games with Pygame course.

A miss should cost something. Give the player 3 lives and take one away each time a block falls past the bottom. You already have the place in the code where that happens: the block.top > 360 branch.

if block.top > 360:
    block.y = -20
    block.x = random.randint(0, 460)
    lives -= 1

Show the lives the way you show the score: render f"Lives: {lives}" every frame and blit it in the top right corner, at (370, 10).

Challenge

Easy

Before the loop, set lives = 3.
Take one away when a block falls past the bottom.
Render f"Lives: {lives}" in (240, 240, 240) and blit it at (370, 10).

Try it yourself

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)
        score += 1

    screen.fill((30, 30, 46))
    pygame.draw.rect(screen, (80, 160, 255), basket)
    pygame.draw.rect(screen, (235, 80, 80), block)
    score_text = font.render(f"Score: {score}", True, (240, 240, 240))
    screen.blit(score_text, (10, 10))
    pygame.display.flip()
    clock.tick(60)
