Unity 3d转2d再转3d

我是用daydream平台测试的，目前别的平台还没有测试

大概思路是playerSettings 中设置勾选Virtual Reality Supported 后选着对应的平台这里选的是Daydream 



然后在转换平台时用下面的方法加载到对应的平台，

UnityEngine.XR.XRSettings.LoadDeviceByName("None")

UnityEngine.XR.XRSettings.LoadDeviceByName("daydream");

并设置UnityEngine.XR.XRSettings.enabled = true;就可以切换到vr模式了

在同一个场景中增加两个MainCamera，



下面把脚本附上

using System.Collections;

using System.Collections.Generic;

using UnityEngine;

using UnityEngine.EventSystems;

using UnityEngine.XR;

public class Manger3dTo2d : MonoBehaviour

{

    private bool is3d = true;

    public GameObject canvas;

    public GameObject mainCamare;

    public GameObject camare;

    //public GameObject evenSystem;

    public TextMesh tm;

    //public GameObject hand;
// Use this for initialization
void Start ()
{
    tm.text = XRSettings.loadedDeviceName;
    Debug.Log(XRSettings.loadedDeviceName + "333");
    is3d = true;
canvas.SetActive(false);
    camare.SetActive(false);
}

// Update is called once per frame
void Update () {

        if ((GvrControllerInput.AppButtonUp || Input.GetKeyUp(KeyCode.A)) && is3d)
    {
        canvas.SetActive(true);
        is3d = false;

            
        //UnityEngine.XR.XRSettings.enabled = false;
        XRSettings.LoadDeviceByName("None");

            Debug.Log(XRSettings.loadedDeviceName);
        tm.text = XRSettings.loadedDeviceName;
        //evenSystem.GetComponent<GvrPointerInputModule>().enabled = false;
        //evenSystem.GetComponent<StandaloneInputModule>().enabled = true;

            mainCamare.SetActive(false);

            camare.SetActive(true);

            //hand.SetActive(false);
    }

        if (GvrControllerInput.ClickButtonDown || Input.GetKeyUp(KeyCode.B))

        {

            To3d();

        }
}

    public void To3d()

    {        

        StartCoroutine(VrOn());    

    }

    IEnumerator VrOn()

    {

        XRSettings.LoadDeviceByName("daydream");

        Debug.Log
4000
(XRSettings.loadedDeviceName + "1111");

#if UNITY_EDITOR

#endif

#if UNITY_ANDROID

        yield return new WaitUntil(() => XRSettings.loadedDeviceName == "daydream");//到这一步pc不能测试了

#endif

        Debug.Log(XRSettings.loadedDeviceName + "222");

        yield return null;

        XRSettings.enabled = true;

        Debug.Log(XRSettings.loadedDeviceName);

        tm.text = XRSettings.loadedDeviceName;

        canvas.SetActive(false);

        is3d = true;

        mainCamare.SetActive(true);

        camare.SetActive(false);

        //hand.SetActive(true);

        //evenSystem.GetComponent<GvrPointerInputModule>().enabled = true;

        //evenSystem.GetComponent<StandaloneInputModule>().enabled = false;

    }

    public void ButtonClick()

    {

        Debug.Log("这是2d场景");

    }

}
