In this context, to shoot bullets using the spacebar, we recommend adopting a more efficient approach by utilizing lists to manage bullet positions. This involves creating a list (bullet_list) that stores the bullet's initial positions recorded as [start_x, start_y] coordinates. When the bullet is fired, this list is then appended with the current position of the firing object (i.e., player or enemy).
To handle bullet movement and rendering, we employ nested loops. The outer loop iterates through each bullet in the list, while the inner loop handles the movement and drawing of individual bullets. If any bullet exits the screen, it is subsequently removed from the list.
Here's an improved code snippet that incorporates these methods:
<code class="python">bullet_list = [] while run == True: # Handle events for event in pygame.event.get(): if event.type == pygame.QUIT: run = False elif event.type == pygame.KEYDOWN and event.key == pygame.K_SPACE: bullet_list.append([start_x, start_y]) # Update bullet positions for bullet_pos in bullet_list[:]: bullet_pos[0] += move_bullet_x bullet_pos[1] += move_bullet_y if not screen.get_rect().colliderect(bullet_image.get_rect(center = bullet_pos): bullet_list.remove(bullet_pos) # Draw remaining bullets for bullet_pos in bullet_list: screen.blit(bullet_image, bullet_image.get_rect(center = bullet_pos))</code>
Additionally, remember to use Pygame's key_get_pressed() function to monitor key states and adjust player movement accordingly. By implementing these techniques, you can achieve smoother and more efficient bullet firing within your game.
