Changing scene room duplicates XR Origin

When I change room and scene it seems to keep my XR Origin Rig, so everytime I change room/scene it creates a new one. I have seen some people just remove their XR origin rigs of the scene they are going to. However I have different Rigs for each scene, so I need to leave the XR rigs in the scene. So I'm thinking I need to destroy some before I connect to a new room?
Here is my code:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using Normal.Realtime;
using UnityEngine.SceneManagement;
using UnityEngine.XR.Interaction.Toolkit;

public class NormalSceneLoader : MonoBehaviour
{
[SerializeField] private Realtime realtime;
[SerializeField] private string roomName;
[SerializeField] private int sceneIndex;

private XRGrabInteractable grabInteractable;

private bool isLoading;

void Start()
{
grabInteractable = GetComponent<XRGrabInteractable>();
grabInteractable.selectEntered.AddListener(OnSelectEntered);
}
void OnSelectEntered(SelectEnterEventArgs args)
{
LoadScene();
}

public void LoadScene()
{
if (isLoading) return;
isLoading = true;
realtime.Disconnect();
realtime = null;

SceneManager.LoadScene(sceneIndex);

realtime = FindObjectOfType<Realtime>();
realtime.Connect(roomName);

isLoading = false;
}
}

Hi @xulipa. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base.

----------------------
It seems like you're experiencing an issue where a new XR Origin Rig is created every time you change rooms or scenes. This could be due to the fact that your XR Origin Rigs are not being properly cleaned up when you switch scenes.

In your current code, you're disconnecting from the room and setting to

null

null

before loading a new scene. However, you're not explicitly destroying the XR Origin Rig. This could be why you're seeing duplicates.

One way to handle this is to destroy the XR Origin Rig before you load a new scene. You can do this by finding the XR Origin Rig in your scene and calling on it. However, you mentioned that you have different Rigs for each scene, so you need to be careful to only destroy the Rig that's currently in use.

Here's an example of how you might modify your method to destroy the current XR Origin Rig:

This code finds the in your scene, which should be a component on your XR Origin Rig, and destroys its associated game object. This should effectively remove the current XR Origin Rig from your scene.

Please note that this is a general solution and might need to be adapted based on your specific project setup. Also, remember to be careful when destroying objects, as it can lead to unexpected behavior if not handled correctly.

the only reason that your xrorigin isn't being destoryed on scene change is that DontDestroyOnLoad was called on it at some point, just do a search for that code in your IDE and remove it.

So that's some native Unity system code I would be looking for?

Mechabit•8/14/24, 3:53 PM

it's nothing in normcore doing it for sure

xulipaOP•8/14/24, 3:53 PM

Because in this video I see that they are removing their XR Origin from the scene. Which I cannot because I'm using a different XR Origin for every scene: https://www.youtube.com/watch?v=AGMKZcL_CuI

nothing wrong with have a different xr origin in each scene

@Normcore Assistant can you change the script into Additive Scene/Room loading instead

kapa.ai•8/14/24, 5:03 PM

Let me check the knowledge base for you. One moment!

kapa.ai•8/14/24, 5:04 PM

Sure, you can modify your script to use additive scene loading. This can be done using with . This will load the scene asynchronously in the background, without unloading the current scene.

Here's how you might modify your method to use additive scene loading:

In this code, is a callback method that's called when the scene has finished loading. This is where you find the component in the new scene and connect to the new room.

Please note that when using additive scene loading, you'll end up with multiple scenes loaded at the same time. If you want to unload the previous scene after the new one has loaded, you can do so using .

Also, remember that when using additive scene loading, each scene will have its own set of game objects, and these are not automatically cleaned up when you load a new scene. You'll need to manage this yourself, for example by destroying any game objects that you don't need anymore.
