// 获取Player变量指定的对象的三围坐标
Vector3 player_postion = Player.transform.position;
// 获取X,Y,Z值
float x = player_postion.x;
float y = player_postion.y;
float z = player_postion.z;
// 设置应用了当前函数的GameObject的坐标
// 1.直接赋值
this.GetComponent<Transform>().position = player_postion;
// 2.在某GameObject的基础上加
this.GetComponent<Transform>().position = new Vector3(player_postion.x, player_postion.y + 7.79F, player_postion.z - 15);
//或者是
this.GetComponent<Transform>().position = player_postion + new Vector3(0, 7.79F, -15);
