改编思路：
1、添加ball_ctr_flg标签，检查此标签确保每一时刻只有一个小球接受控制
2、改编小球碰撞后运动规则：小球碰撞后将两个小球的速度交换，而不是原路返回。因为要交换速度，所以需要获得两个碰撞球的速度，故碰撞检测使用的是小甲鱼给出的第一种方法。
3、在定义球类时，我把速度属性直接定义到球里
目前发现存在的问题：
1、游戏结束后，只有loser_sound，而laugh_sound并不执行
2、每次游戏控制2个球入洞后，再也无法通过鼠标移动来控制球，不知道哪里的问题
3、在碰撞过程中，自认为理论上不应该存在两个小球堆一起抖啊抖分不开的情况，但实际还是有
4、开始在写控制球的移动按键部分时，直接用each.speed[0] += 1等方式，但报错了，提示':tuple' does object not support item assignment，看这意思是把each.speed看成元组了，但我明明用的列表形式啊，不懂~
以上问题有点多，如有大神肯费心知道一二，不胜感激！
