Cardboard

8. @joaolaq@joaolaq
Unity
https://unity3d.com/

9. @joaolaq@joaolaq
Cardboard/Daydream Native support
in
Unity (5.6+)

10. @joaolaq@joaolaq
Download Unity 5.6+
Suggest Brand New 2017.1.1 but beware the bugs

11. @joaolaq@joaolaq
Download GoogleVR
https://github.com/googlevr/gvr-unity-sdk/releases

12. @joaolaq@joaolaq
Import Google VR and Assets

13. @joaolaq@joaolaq
Open Sample Scene
• Camera
• Reticle

14. @joaolaq@joaolaq
Input?
• GvrEventSystem

15. @joaolaq@joaolaq
Let’s build and run!

16. @joaolaq@joaolaq
And on S8 It Crash :)
Could not recreate VR window because GfxDevice is in an invalid state (device lost)

17. @joaolaq@joaolaq
Solution:
Put Daydream Support before Cardboard ;)

18. @joaolaq@joaolaq
• DayDream! We can use the same SDK
See the controller!

19. @joaolaq@joaolaq
Input
• GvrControllerPointer

20. @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

25. @joaolaq@joaolaq
• Camera = OVRCameraRig

26. @joaolaq@joaolaq
• Controller

27. @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);
}
