Question How to determine if left or right controller now that ControllerNode is removed

In the previous release I would do something like when an interactable was grabbed from the OnSelect

Code (CSharp):

1. var xrNode = interactor.GetComponent<XrController>().controllerNode;
2. leftOrRight= InputDevices.GetDeviceAtXRNode(xrNode);

Now I know if its the left hand or the right hand that grabbed on object, but that controllerNode has been removed from the controller. Whats the proper way to determine this now?

 

Some extra context.

Old Controller


New Controller

 

Hi there, did you find a solution? I'm struggling with same issue.

Thanks

 

I use the input events system. then I have duplicate mappings for left and for right controllers. see XR Toolkit demo for example.

Then I can take InputActionReference as parameter for my script, and use either action.performed event or action.ReadValue<T>()

This method you can also have both controllers activate the same function but also know which one is the input source.

 

Thanks a lot! I'll try this

 

I have learned that if it's a button action (like Activate or Select which are trigger and grip buttons respectively) action.triggered only gets updated on button push, not release or hold down. you can detect push with action.triggered, detect is down with action.phase == InputActionPhase.Start and up with action.phase != Start (specifically Waiting but note it can also be disabled or something)

 

Ok. I've taken another approach, which feels very very dirty, but does the job. I give left and right hand a tag. This code is triggered on the OnSelectEntered event.

Code (CSharp):

1.         var controller = GetComponent<XRGrabInteractable>();
2.  
3.         if (controller.selectingInteractor.tag.Equals("HandLeft"))
4.         {
5.             isLeftHandHoldingGun = true;
6.          }
7.         else if (controller.selectingInteractor.tag.Equals("HandRight"))
8.         {
9.             isRightHandHoldingGun = true;
10.         }
