Unity屏蔽Oculus陀螺仪

1、打开Unity,PlayerSetting设置虚拟现实技术支持，勾选Oculus。

2、连接Oculus头盔，并打开Oculus应用，设置允许未知来源（unknown sources）使用

3、导入OculusUtilities插件，然后Unity中会多两个文件夹，分别为OVR和Plugins。

4、在OVR中找到Scenes文件夹，打开Cubes场景

5、创建FakeTracking脚本，代码如下：

using UnityEngine;

using System.Collections;

public class FakeTracking : MonoBehaviour {

    public OVRPose centerEyePose = OVRPose.identity;

    public OVRPose leftEyePose = OVRPose.identity;

    public OVRPose rightEyePose = OVRPose.identity;

    public OVRPose leftHandPose = OVRPose.identity;

    public OVRPose rightHandPose = OVRPose.identity;

    public OVRPose trackerPose = OVRPose.identity;

    void Awake()

    {

        OVRCameraRig rig = GameObject.FindObjectOfType<OVRCameraRig>();

        if (rig != null)

            rig.UpdatedAnchors += OnUpdatedAnchors;

    }

    void OnUpdatedAnchors(OVRCameraRig rig)

    {

        if (!enabled)

            return;

        //This doesn't work because VR camera poses are read-only.  

        //rig.centerEyeAnchor.FromOVRPose(OVRPose.identity);  

        //Instead, invert out the current pose and multiply in the desired pose.  

        OVRPose pose = rig.centerEyeAnchor.ToOVRPose(true).Inverse();

        pose = centerEyePose * pose;  rig.trackingSpace.FromOVRPose(pose, true);

        //OVRPose referenceFrame = pose.Inverse();  

        //The rest of the nodes are updated by OVRCameraRig, not Unity, so they're easy.  

        //forums.oculus.com/vip/discussion/comment/446956/  

        rig.leftEyeAnchor.FromOVRPose(leftEyePose);

        rig.rightEyeAnchor.FromOVRPose(rightEyePose);

        rig.leftHandAnchor.FromOVRPose(leftHandPose);

        rig.rightHandAnchor.FromOVRPose(rightHandPose);

        rig.trackerAnchor.FromOVRPose(trackerPose);

    }

} 

6、将FakeTracking脚本挂载到与OVRManager脚本同一个物体下

7、佩戴Oculus头盔，运行项目，此时场景画面将不会随着Oculus旋转而旋转，如果会发现Oculus显示的画面会有点抖动，这个官方暂时还无法解决。
