Pygameでプレイヤーの消失を修正し、スペースバーを使用して弾丸射撃を実装する方法は?

<code class="python">bullets = []

while True:

    # Event handling
    for event in pygame.event.get():
        pass

    if event.type == pygame.KEYDOWN:
        if event.key == pygame.K_SPACE:
            bullets.append(Bullet(p.x+p.width//2, p.y))
        if event.key == pygame.K_LEFT:
            p.move_left()
        if event.key == pygame.K_RIGHT:
            p.move_right()

    # Update objects
    keys = pygame.key.get_pressed()
    if keys[pygame.K_LEFT]:
        p.move_left()
    if keys[pygame.K_RIGHT]:
        p.move_right()
    for b in bullets:
        b.update()
        if b.y <= 0:
            bullets.remove(b)

    # Clear display
    d.fill((98, 98, 98))

    # Draw scene
    for b in bullets:
        b.draw()
    p.draw()

    # Update display
    win.update()</code>
