Obsolete This is obsolete, and should no longer be used. Instead, find the active XRDisplaySubsystem and check that the running property is true (for details, see XRDevice.isPresent documentation). public static bool isPresent;

Description

Successfully detected a XR device in working order.

This property is obsolete and will be removed in an upcoming release.

Instead, find the active XRDisplaySubsystem and check to see if it is running. The example illustrates this process.

using System.Collections.Generic;
using UnityEngine;
using UnityEngine.XR;
internal static class ExampleUtil
{
    public static bool isPresent()
    {
        var xrDisplaySubsystems = new List<XRDisplaySubsystem>();
        SubsystemManager.GetInstances<XRDisplaySubsystem>(xrDisplaySubsystems);
        foreach (var xrDisplay in xrDisplaySubsystems)
        {
            if (xrDisplay.running)
            {
                return true;
            }
        }
        return false;
    }
