Pygameで弾の同時発射を防ぐことはできますか?

<code class="python">if len(bullets) < 5:  # Max bullets on screen
    # Fire a bullet with the appropriate facing

<code class="python"># Get the current time in milliseconds
current_time = pygame.time.get_ticks()

# Check if the current time exceeds the next bullet threshold
if current_time > next_bullet_threshold:

    # Set the next bullet threshold to a time in the future (e.g., 500 milliseconds later)
    next_bullet_threshold = current_time + bullet_delay

    # Fire a bullet with the appropriate facing and other logic
