​
Setup

XRGrabInteractable on the handle + ValveInteraction + optional ReferenceableComponent for ValveStep.

​
Role

Projects hand motion onto a plane, drives handle rotation, exposes angle subscriptions and limits (see serialized fields and public API in source).

​
Code

Inspector UnityEvent hooks are the usual integration path. From code, the same events are exposed as fields on ValveInteraction: 
using MolcaSDK.VR.Interactions;
using UnityEngine;

public class ValveAudio : MonoBehaviour
{
    [SerializeField] private ValveInteraction valve;

    private void OnEnable()
    {
        valve.onRotationChanged.AddListener(OnAngle);
        valve.onFullRotation.AddListener(OnFullTurn);
    }

    private void OnDisable()
    {
        valve.onRotationChanged.RemoveListener(OnAngle);
        valve.onFullRotation.RemoveListener(OnFullTurn);
    }

    private void OnAngle(float degrees) { }
    private void OnFullTurn() { }
}

​
Troubleshooting

  • Handle does not rotate — Check valveHandle, rotationAxis, lock state, and that XRGrabInteractable fires select events on this rig.
  • Target angle never reached — ValveStep uses SubscribeToAngle against accumulated rotation; align targetAngle with min/max clamp and startAngle.
  • Jitter or axis wrong — Toggle useInteractableTransform vs explicit handle; verify axis is in handle local space.
