Touch Controller Haptics Don't Work in Unity Scene?

[olly.356959]

Hi all,

I'm coding a VR experiment in Unity using the Meta Quest 3. Everything works so far, but I can't for the life of me figure out why my haptic don't work? Here's a snippet of my code just in case I'm missing something obvious: 

using System.Collections;

using UnityEngine;

 

public class ScreenOverlay : MonoBehaviour

{

    public Canvas overlayImage;

    public Haptic1 hapticScript; // Reference to the Haptic1 script

    private float hapticDuration = 0.5f;

 

    private void Start()

    {

        // Ensure the overlay image is initially disabled

        overlayImage.enabled = false;

 

        // Find and get the CartAppearance script

        hapticScript = Object.FindFirstObjectByType<Haptic1>();

    }

 

    private void Update()

    {

        // Detect index button press on the left controller and trigger the flash effect

        if (OVRInput.GetDown(OVRInput.Button.PrimaryIndexTrigger, OVRInput.Controller.LTouch))

        {

            FlashScreen();

 

            StartCoroutine(TriggerHapticFeedback());

        }

    }

 

    private void FlashScreen()

    {

        // Enable the overlay image to simulate the flash effect

        overlayImage.enabled = true;

 

        // Delay for a short duration (e.g., 0.1 seconds)

        StartCoroutine(DisableOverlayAfterDelay(0.1f));

    }

 

    private IEnumerator DisableOverlayAfterDelay(float delay)

    {

        // Wait for the specified delay

        yield return new WaitForSeconds(delay);

 

        // Disable the overlay image after the delay

        overlayImage.enabled = false;

    }

    private IEnumerator TriggerHapticFeedback()

    {

        OVRInput.SetControllerVibration(1, 1, OVRInput.Controller.LTouch);

        yield return new WaitForSeconds(hapticDuration);

        OVRInput.SetControllerVibration(0, 0, OVRInput.Controller.LTouch);

    }

}

I have set up the Meta XR All-in-one SDK in unity and the controller/hand/head tracking is all working fine.
