Gaze Pointers & Drop Down Boxes

When I use a Drop Down box the Gaze Pointer disappears as it hovers over the items, is this a known issue?

    I think I've tracked it down to the OVRInputModule.GetGazePointerData

    OVRRaycaster ovrRaycaster = raycast.module as OVRRaycaster;
     
    overRaycaster is Null, I wonder if this has anything to do with the fact the DropList doesn't exist until it is dropped down?

    OK, worked it out, the DropdownList GameObject that is created when the list is dropped down contains its own Canvas... I'll see if I can add the OVRRaycaster Component when it is instantiated...

    I may continue to look for a better way, but for now my dropdown menus are working in VR when I add this to the UI script:






        // HACK for selecting dropdowns in vr

        private void Update() {

            if (XRSettings.isDeviceActive) {

                var found = gameObject.GetComponentsInChildren<GraphicRaycaster>();

                foreach (var gr in found) {

                    var ovr = gr.GetComponent<OVRRaycaster>();

                    if (ovr == null) {

                        gr.enabled = false;

                        ovr = gr.gameObject.AddComponent<OVRRaycaster>();

                        ovr.sortOrder = 20;

                    }

                }

            }

        }      

    Basically, the idea is to look for GraphicRaycaster components (which are on the dropdown canvases) and replace with OVRRaycaster.

    What you can do is add this script to your Template inside your Dropdown 
    using System.Collections;
    using System.Collections.Generic;
    using UnityEngine;
    using UnityEngine.UI;

    public class CanvasVRModifier : MonoBehaviour
    {
        public GameObject pointer;
        private void Awake()
        {
            GraphicRaycaster gr = GetComponent<GraphicRaycaster>();
            OVRRaycaster OVRrc = null;
            if (gr != null)
            {
                gr.enabled = false;
                OVRrc = gameObject.AddComponent<OVRRaycaster>();
                OVRrc.pointer = pointer;
                OVRrc.blockingObjects = OVRRaycaster.BlockingObjects.All;
            }
        }
    }
