if (Input.GetKey (KeyCode.W)) {//相当于position+=    Rig.MovePosition (Rig.position + transform.forward * Time.deltaTime);    }if (Input.GetKey (KeyCode.S)) {    Rig.MovePosition (Rig.position - transform.forward * Time.deltaTime);    }float hor = Input.GetAxis ("Horizontal");//相当于Rotation*=Rig.MoveRotation (Rig.rotation * Quaternion.AngleAxis (hor, Vector3.up));
