Unity GoogleVR（二）—— 动态切换VR/2D模式

1、下载最新版GoogleVR For Unity后，导入新建的Unity工程。
2、根据上篇文章中所讲的操作步骤对PlayerSetting进行设置(第6步往后)
3、对Assets/GoogleVR/Demos/Scenes/HelloVR场景进行打包发布

4、动态开启/关闭VR模式
新建脚本VRMode.cs将其挂载到场景中任意对象上

using UnityEngine;
using UnityEngine.XR;

public class VRMode : MonoBehaviour
{
    
    
    public Camera vrCamera;

    //当前是否在VR模式下
    public static bool VrMode => XRSettings.enabled;

    private void Reset()
    {
    
    
        vrCamera = Camera.main;
    }

    // Start is called before the first frame update
    void Start()
    {
    
    
        SwitchToVR();
    }

    private void Update()
    {
    
    
#if UNITY_EDITOR
#else
        //在2D模式下，需要自己控制摄像机的旋转
        if (!VrMode)
        {
    
    
            Quaternion headQuaternion = UnityEngine.XR.InputTracking.GetLocalRotation(UnityEngine.XR.XRNode.Head);
            vrCamera.transform.rotation = Quaternion.Slerp(transform.rotation, headQuaternion, 10);
        }
#endif
    }

    /// <summary>
    /// 进入VR画面
    /// 进入VR画面
    /// </summary>
    public static void SwitchToVR()
    {
    
    
        XRSettings.enabled = true;
    }

    /// <summary>
    /// 进入2D画面
    /// </summary>
    public static void SwitchTo2D()
    {
    
    
        XRSettings.enabled = false;
    }

    void OnGUI()
    {
    
    
        int width = 200;
        int height = 50;
        int left = Screen.width / 2 - width / 2;
        int top = Screen.height - height - 10;

        string text = VrMode ? "To 2D" : "To VR";

        if (GUI.Button(new Rect(left, top, width, height), text))
        {
    
    
#if UNITY_EDITOR
#else
            if (VrMode == true)
            {
    
    
                SwitchTo2D();
            }
            else
            {
    
    
                SwitchToVR();
            }
#endif
        }
    }
}

5、运行时点击此处切换VR/2D模式


6、在Unity编辑器运行时，并不会分屏显示。Ctrl + 鼠标移动模拟Roll，Alt + 鼠标移动模拟Yaw/Pitch，Shift+鼠标中键为Recenter功能
