Help with VR gaze system

Hello,

I started to make a simple VR gaze system from scratch, using Unity ARFoundation. First thing was to draw a line from my point of view to "infinity", like a pointer. I have this script running on my AR Session Origin at Update:

Code (CSharp):

1.            
2.             myLine.SetPosition(0, transform.position);
3.             myLine.SetPosition(1, transform.position+(transform.forward*1000));
4.  

This works on editor, I have a line, and I can turn and move my session origin (my "head" with camera), it follows up.

But, when I use it on mobile... the line keeps still, doesnt turn and move with the device.

What´s wrong?

 

Oh well... nevermind. I solve it. I needed a reference to the arCameraManager, it holds the head-tracking information.

Code (CSharp):

1.  
2.     myLine.SetPosition(0, arCameraManager.transform.position);
3.     myLine.SetPosition(1, arCameraManager.transform.position+arCameraManager.transform.forward*100));
4.
