Import Google VR and Assets

Open Sample Scene • Camera • Reticle

@joaolaq@joaolaq

Input?

• GvrEventSystem

@joaolaq@joaolaq

Let’s build and run!

@joaolaq@joaolaq

And on S8 It Crash :)

Could not recreate VR window because GfxDevice is in an invalid state (device lost)

@joaolaq@joaolaq

Solution:

Put Daydream Support before Cardboard ;)

@joaolaq@joaolaq

• DayDream! We can use the same SDK See the controller!

@joaolaq@joaolaq

Input • GvrControllerPointer

@joaolaq@joaolaq

void Update() {

  // Example: get controller's current orientation:  Quaternion ori = GvrController.Orientation;

  // If you want a vector that points in the direction of the controller  // you can just multiply this quat by Vector3.forward:  Vector3 vector = ori * Vector3.forward;

  // ...or you can just change the rotation of some entity on your scene  // (e.g. the player's arm) to match the controller's orientation  playerArmObject.transform.localRotation = ori;

  // Example: check if touchpad was just touched  if (GvrController.TouchDown) {    // Do something.    // TouchDown is true for 1 frame after touchpad is touched.  }

  // Example: check if app button was just released.  if (GvrController.AppButtonUp) {    // Do something.    // AppButtonUp is true for 1 frame after touchpad is touched.  }

  // Example: check the position of the user's finger on the touchpad  if (GvrController.IsTouching) {    Vector2 touchPos = GvrController.TouchPos;    // Do something.  }}

GvrController API

• Controller

@joaolaq@joaolaq

// old way // if (Input.GetMouseButton(0)) // the finger has touched the HMD trackpad. // { // Vector2 touchPosition = Input.mousePosition; // ProcessClickAtPosition(touchPosition); // }

// new way // The Gear VR Controller has a clickable trackpad, so we can differentiate between // the finger simply touching the pad and actively depressing it.

// is player using a controller? if (OVRInput.GetActiveController() == OVRInput.Controller.LTrackedRemote || OVRInput.GetActiveController() == OVRInput.Controller.RTrackedRemote) { // yes, are they touching the touchpad? if (OVRInput.Get(OVRInput.Touch.PrimaryTouchpad)) { // yes, let's require an actual click rather than just a touch. if (OVRInput.Get(OVRInput.Button.PrimaryTouchpad)) { // button is depressed, handle the touch. Vector2 touchPosition = OVRInput.Get(OVRInput.Axis2D.PrimaryTouchpad); ProcessControllerClickAtPosition(touchPosition); } } } else if (OVRInput.Get(OVRInput.Touch.PrimaryTouchpad)) // finger on HMD pad? { // not using controller, same behavior as before. Vector2 touchPosition = OVRInput.Get(OVRInput.Axis2D.PrimaryTouchpad); ProcessHMDClickAtPosition(touchPosition); }
