XRDevice.isPresent

描述

成功检测到一台处于正常运行状态的 XR 设备。

This property is obsolete and will be removed in an upcoming release.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;
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;
    }
}
public class CheckXRDisplay : MonoBehaviour
{
    void Awake()
    {
        Debug.Log("Do we have an Active Display? " + ExampleUtil.isPresent().ToString());
    }
}
