资源准备:
资源准备好之后就创建一个Plane，把他放在相机的下面，成为相机的子物体，再创建4个空物体作为锚点
下面就是代码了:

public GameObject RightTop;
public GameObject LeftBottom;
public GameObject RightBottom;

Vector3 LBPos;
Vector3 RBPos;
Vector3 PointPos;//当前点选的位置
float gridWidth = 1; //棋盘网格宽度
float gridHeight = 1; //棋盘网格高度
float minGridDis; //网格宽和高中较小的一个
Vector2[,] chessPos; //存储棋盘上所有可以落子的位置
int[,] chessState; //存储棋盘位置上的落子状态
enum turn { black, white };
turn chessTurn; //落子顺序
public Texture2D white; //白棋子
public Texture2D black; //黑棋子
public Texture2D blackWin; //白子获胜提示图
