我写了个pygame程序
```python

MAX_BULLETS=3 #子弹
SPACESHIP_WIDTH=55 # 飞船宽
SPACESHIP_HEIGHT=40 # 飞船高
BORDER=pygame.Rect(WIDTH//2,0,10,HEIGHT) # 中间线大小
BLAKE=(0,0,0) # 颜色
RED=(255,0,0)
YELLOW=(255,100,0) # 使黄色更显眼

draw_window(red,yellow,red_bullets,yellow_bullets)
pygame.quit() # 退出游戏
但音效和背景音乐总是有矛盾
移动飞船，背景音乐就会重新播放
发射子弹，背景音乐也会重新播放
求帮助
