Creating an Inventory in Unity 3D - adapting from Oculus to HTC - unity3d

Question

I am trying to make a simple inventory in Unity 3D for virtual environment. I am using StemVR plugin, because I have HTC Vive. I was following this tutorial, made for Oculus (https://www.youtube.com/watch?v=gAz_SeDUQBk&t=310s) and now I have to adapt the code for HTC Vive, but I don't know how.
In the slot script I have a problem with this part of the script, where it should release an item after releasing a trigger:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
using Valve.VR;
public class Slot : MonoBehaviour
{
public GameObject ItemInSlot;
public Image slotImage;
void Start()
{
slotImage = GetComponentInChildren<Image>();
originalColor = slotImage.color;
}
private void OnTriggerStay(Collider other)
{
if (ItemInSlot != null) return;
GameObject obj = other.gameObject;
if (!IsItem(obj)) return;
if (OVRInput.GetUp(OVRInput.Button.SecondaryHandTrigger))
{
InsertItem(obj);
}
}
bool IsItem(GameObject obj)
{
return obj.GetComponent<Item>();
}
void InsertItem(GameObject obj)
{
obj.GetComponent<Rigidbody>().isKinematic = true;
obj.transform.SetParent(gameObject.transform, true);
obj.transform.localPosition = Vector3.zero;
obj.transform.localEulerAngles = obj.GetComponent<Item>().slotRotation;
obj.GetComponent<Item>().inSlot = true;
obj.GetComponent<Item>().currentSlot = this;
ItemInSlot = obj;
}
}
And in Inventory script I have a problem with adapting this part:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
using Valve.VR;
public class InventoryVR : MonoBehaviour
{
public GameObject Inventory;
public GameObject Anchor;
bool UIActive;
private void Start()
{
Inventory.SetActive(false);
UIActive = false;
}
private void Update()
{
if (OVRInput.GetDown(OVRInput.Button.Four))
{
UIActive = !UIActive;
Inventory.SetActive(UIActive);
}
}
}
What functions can I use to make this applicable for HTC Vive?
