Unity Steam VR如何引用当前持有的对象？

using UnityEngine;
using Valve.VR;

public class MyController : MonoBehaviour
{
    private SteamVR_TrackedObject trackedObj;
    private SteamVR_Controller.Device device;

    void Awake()
    {
        trackedObj = GetComponent<SteamVR_TrackedObject>();
    }

    void Update()
    {
        device = SteamVR_Controller.Input((int)trackedObj.index);
        if (device.GetPressDown(SteamVR_Controller.ButtonMask.Trigger))
        {
            GameObject heldObject = device.GetPressDown(SteamVR_Controller.ButtonMask.Trigger);
            // 在这里处理当前持有的对象
        }
    }
}

using UnityEngine;
using Valve.VR.InteractionSystem;

public class MyHand : MonoBehaviour
{
    private Hand hand;

    void Awake()
    {
        hand = GetComponent<Hand>();
    }

    void Update()
    {
        if (hand.GetStandardInteractionButtonDown())
        {
            GameObject heldObject = hand.currentAttachedObject;
            // 在这里处理当前持有的对象
        }
    }
}
