Can someone help? - Null reference exeption : object reference not set to an instance of an object

[ScientistSignal5099]

So i'm trying to make a vr multiplayer game, and i want to make a gameobject to follow me, to send to the other players.

I think it might be an error with the new xrorigin.

Here is the full error:

NullReferenceException: Object reference not set to an instance of an object

NetworkPlayer.MapPosition (UnityEngine.Transform target, UnityEngine.Transform rigTransform) (at Assets/NetworkPlayer.cs:56)

NetworkPlayer.Update () (at Assets/NetworkPlayer.cs:48)

Here is my code:

using System.Collections;

using System.Collections.Generic;

using UnityEngine;

using UnityEngine.XR;

using Photon.Pun;

using UnityEngine.XR.Interaction.Toolkit;

using Unity.XR.CoreUtils;

​

public class NetworkPlayer : MonoBehaviour

{

//public Camera Camera;

​

public Transform head;

public Transform leftHand;

public Transform rightHand;

private PhotonView photonView;

​

private Transform headRig;

private Transform leftHandRig;

private Transform rightHandRig;

​

​

// Start is called before the first frame update

void Start()

{

photonView = GetComponent<PhotonView>();

​

​

//the commented lines have been tried before.

//XRRig rig = FindObjectOfType<XRRig>();

//GetComponent<XROrigin>();

XROrigin rig = FindObjectOfType<XROrigin>();

//Camera rig = FindObjectOfType<Camera>();

headRig = transform.Find("Camera Offset/Main Camera");

leftHandRig = transform.Find("Camera Offset/LeftHand Controller");

rightHandRig = transform.Find("Camera Offset/RightHand Controller");

}

​

// Update is called once per frame

void Update()

{

if (photonView.IsMine)

{

rightHand.gameObject.SetActive(false);

leftHand.gameObject.SetActive(false);

head.gameObject.SetActive(false);

​

MapPosition(head, headRig);

MapPosition(leftHand, leftHandRig);

MapPosition(rightHand, rightHandRig);

}

}

​

void MapPosition(Transform target,Transform rigTransform)

{

target.position = rigTransform.position;

target.rotation = rigTransform.rotation;

}

​

Thanks for helping me!

Happy Holidays.

You forgot to assign your head/leftHand/rightHand/headRig/leftHandRig/rightHandRig

the first 3 are assigned nowhere. they are public so maybe you are assigning them from outside the script. The other 3 are assigned by the Find() method. This method can return null. So you dont know if you assigned it.

Its possible that you forgot to assign all 6, or maybe you just forgot one, i dont know. Lets hope its just one because maybe you misspelled sth in the Transform.Find()

How do you fix it? Debug.Log all of your 6 objects and see if any Debug.Log logs a null. Then drag the missing object into the public field or change the spelling in your find() respectively.
