在移动过程中就会中断发射子弹。怎么让elif语句匹配完一条后继续匹配下面的语句？

elif event.type == pygame.KEYDOWN:
   if status == 1:
       KEY_down = event.key
       if event.key == pygame.K_w or event.key == pygame.K_UP:
           our_plan.move_up()
       elif event.key == pygame.K_s or event.key == pygame.K_DOWN:
           our_plan.move_down()
       elif event.key == pygame.K_a or event.key == pygame.K_LEFT:
           our_plan.move_left()
       elif event.key == pygame.K_d or event.key == pygame.K_RIGHT:
           our_plan.move_right()
       elif event.key == pygame.K_SPACE:
           # 发射子弹
           our_plan.shoot()
