贪吃蛇之physical edition
融合普通贪吃蛇与打砖块，并加入重力场的新玩法
本是我的答辩作业，不得随意盗窃他人劳动成果
/*-----------------------------------------------------------------
2020.4.4: 发现残影是“自己吃自己”的bug，加入结构体在后台map里储存轨迹即可
2020.4.6： 加入45度角斜抛功能，优化墙角里碰撞反弹不了的bug
2020.4.27: 菜单搞定..默认地图绘制中,自定义地图即将加入
目前bug: 1.菜单界面未知的显示少字
2.后期未知原因有及少数蛇身体节点残留

核心公式： 纵向：X = X0 + Vx*t + 1/2*g* mnVX*t*t;
横向：Y = Y0 + Vy*t;
核心思想： 如果选择时间作为移动参考，则每秒会出现点相差太远
这里反过来，以连续为前提，尝试实现：
分别算出 X 增加一个单位长度 应该增加的 Y 的距离 s1
Y 增加一个单位长度 应该增加的 X 的距离 s2
优先选择更短的作为下一次移动的基准。
X Y 的增加都是1
X,Y浮点型，两个方向的位移累加到他两身上，而gotoxy()坐标只能是int ，故每次用old_x,old_y来承接X,Y
因为实体抛物线是连续的，每一段细微的位移理论上是连续的
因此s1 和 s2 理论上只会是0和1以及少数出现2的跳节
s1=0:下降较快 s2=0:抛物线顶端 都不为0：中间
