When using InstantPreview GvrVRHelpers.GetHeadRotation(); doesnt work anymore.

[whizzkid]

Summary:
When InstantPreview is working (i.e. connected to your phone) then GvrVRHelpers.GetHeadRotation(); doesnt return the correct angle anymore.

Found using:

• Google VR SDK version: 1.120.0
• Unity version: 2017.3.1p3
• Phone manufacturer, model, and O/S version: Samsung galaxy s6
• Viewer manufacturer & model:

Steps to reproduce the issue:

1. turn on Instant Preview
2. run your scene, and have it connect to a phone
3. try to access GvrVRHelpers.GetHeadRotation();

Workarounds:
use Camera.main.transform.rotation; instead.

Thanks for reporting; we'll take a look!

Also, when you use the GyroController https://developers.google.com/vr/develop/unity/guides/magic-window GetHeadRotation doesn't work properly because the GyroController just changes the camera's rotation.. so you'll manually have to workaround that again.

It would be cool if you could actually SetHeadRotation for situations like this.

Hi, we've addressed the first problem, and it should be live with our next release on 5/28. If you want to make a local change on your end before that, it was an issue with branching in the GetHeadRotation's editor code. We've added the following lines inside the #if UNITY_EDITOR statement:

if (InstantPreview.Instance.IsCurrentlyConnected != null) {
return Camera.main.transform.localRotation;
} else {
//prior behavior
}

Regarding the second problem, we'll take a look at detecting the GyroController behavior and getting rotation accordingly.

Accommodating a SetHeadRotation method would be useful, but would require a larger refactor to work well. We'll look into it and let you know what we decide!

This is now fixed in the latest release.
