除了游戏性之外
我们也要考虑记录自己的成绩噢

既然创建了游戏，那就要有分数吧。所以来创建一个计分板，首先创建3个变量用来记录数据，然后来设定计分板的长和高、位置、颜色，sb_height是scoreboard的简写（原谅码趣君的懒惰），而计分板的具体宽度数值将在主程序中编写。同时将这三个数据独立出来，作为不同的元素绘制在画布上，方便分别修改它的位置，颜色，大小。
既然有了计分板，那除了设定计分板长度之外，我们还要给每个Marchboss定义一下分数，并添加到计分板中，再通过scoreboard.blitme()绘制计分板。同时记得要加Marchboss和MarchCaptain 的极限Y坐标稍作更改，加上计分板的y坐标，保证MarchCaptain的出现位置正确并减少程序的工作量。
