Get XR controller from PointerEventData? (Tooltip system)

[R1PFake]

Hello,
I have a ToolTip system which works with the IPointerEnterHandler and IPointerExitHandler interfaces.

The events pass the PointerEventData class. Is there any way to use this information to detect which XR controller (left or right) caused the pointer event, so that I can show the tooltip in the correct hand?

I found the answer in a different thread:

While hovering over UI, how do I get the controller being used?

The Quest has 2 controllers, which both are being used to interact with the UI. The Haptics events on the XRRayInteractor do not trigger. All of the XRBaseInteractable don't fire events when they're attached on UI components. I guess the Event system is not written to fire off those events on UI. Only on physical objects. So what I am trying to do is whenever I hover over UI that is interactable, I want the controller to give off a short little vibration. Like the Quest does when you're navi…

    public void OnPointerEnter(PointerEventData eventData)
    {
        if (eventData is TrackedDeviceEventData trackedDeviceEventData)
        {
            if (trackedDeviceEventData.interactor is XRBaseControllerInteractor xrInteractor)
            {
                // Your code, for example haptic or compare the interactor to left / right
                xrInteractor.SendHapticImpulse(0.25f, 0.25f);
            }
        }
    }
