Roman 718deb06d1 任务：实现基本玩法 
1.策划数学模型
2.搬迁工具类如单例模式模板
3.创建玩家类，用于接受和发出指令、记录玩家信息等
4.创建马类，用来接受信息、物理计算、控制马的碰撞等模拟等
5.实装数学模型，实现马脚的控制
6.探索物理实现方式，给控制点加上碰撞体和刚体，似乎可行
--NG，分离的刚体无法作为整体传递力，脚的反作用力传不到身体上
7.把操控分组，左摇杆控制后两条腿、右摇杆控制前两条腿
8.探索物理的实现方式，尝试仅在主物体上挂载仅一个刚体，探索碰撞体组的使用方式/
（（1.给马添加四个碰撞体代表马足
（（2.每帧刷新碰撞体的偏移，使其对准真实马蹄位置，所以需要找准offset和世界空间下位置的对应关系
（（3.如何让马前进？目前发现无法使用真实物理的反作用力，只能根据输入或其他信息算出这个反作用力
（（（1.最终应该通过原速度 + 计算出输入速度，不能使用力，因为使用力涉及的参数极多，很难修改
（（（2.应该通过马足真实位置计算输入速度，不能使用控制点位置
（（（3.每只足应该记住自己上一帧的位置，并每帧更新
（（4.本帧位置减上帧位置 = 运动速度，一个二维向量
（（5.并非一直有效，当本帧马足位置低于圆心 + 调整值时，才有效，否则该足贡献的速度为0.同时，需要有输入才有效，若无输入，同样贡献速度为0
（（6.NG，主要在判断速度是否有效上出了问题，试试每帧给足和地面测距，小于阈值的才给过，然后才加速度
（（7.GoodJob！通过上述方法和其他细微调整，已经使得马可以行走，并且得到不错的效果。但是肯定还有问题，需要后期更进一步调整

目前马能够受到控制，并且可以走动。同样支持键盘游玩，但是体验极差
