How to solve tge 'An object references is required for the non-static field, method, or poroperty' with the GvrBasePointer.LineEndPoint?

I'm new at Unity (and VR) and I'm making a VR game with the GoogleCardboard API and I'm trying to that when the user gaze an object, it can be attach to the GvrReticle so that can move it at will. I found a way to do it by GvrBasePointer.LineEndPoint, but when it compiles it appears the CS0120 error. Here's the code :

using System.Collections; using System.Collections.Generic; using UnityEngine; using UnityEngine.EventSystems;

public class cambio : MonoBehaviour {

 float distance = 10;

 public Rigidbody rb;

 public Vector3 teleportPoint;
 // Use t$$anonymous$$s for initialization
 void Start () {
     rb = GetComponent<Rigidbody>();
 }
 
 // Update is called once per frame
 void Update () {
     
 }

 public void cambiaColor()
 {
     gameObject.GetComponent<Renderer>().material.color = Color.yellow;
     
 }
 public void regreso()
 {
     gameObject.GetComponent<Renderer>().material.color = Color.red;
     
 }
 public void mover()
 {
         rb.GetComponent<Renderer>().material.color = Color.green;
     Vector3 LineEndPoint = new Vector3(GvrBasePointer.LineEndPoint.x, GvrBasePointer.LineEndPoint.y, distance);
     Vector3 objPosition = Camera.main.ScreenToWorldPoint(LineEndPoint);
     transform.position = objPosition;
         //transform.position = new Vector3(transform.position.x+5, transform.position.y, transform.position.z);
 }

}

I would like a way to solve t$$anonymous$$s problem or even another way to ac$$anonymous$$ve what I want to do.
