How to get access to hand object in 4.1.5?

[JohnTitor]

Hi all,

I'm new to working with Leap motion and have to work with Unity 5.4.1 for a project, where only the core 4.1.5 is the recent compatible version. When I want to interact with an object (pick-up the object), I want to parent the object to a hand (probably the brush hand that is holding the object) and de-parent whenever I release the object.

I'm currently struggling to get a reference to the hand object. I tried to following from an old post: https://community.leapmotion.com/t/orion-get-hand-gameobject-by-hand-id/4873. I currently put a getter in LeapHandController to access the dictionary, after that I don't know what to do with the HandProxy (can't seem to get the HandModel). My current script attached on an empty gameobject:

public class CustomDebugHand : MonoBehaviour {

    LeapProvider provider;
    public LeapHandController controller;
    public HandProxy handProxy;
    public List<Leap.Hand> hands = new List<Leap.Hand>();

    // Use this for initialization
    void Start () {
        provider = FindObjectOfType<LeapProvider>() as LeapProvider;
        controller = FindObjectOfType<LeapHandController>() as LeapHandController;
    }
	
	// Update is called once per frame
	void Update () {
        Frame frame = provider.CurrentFrame;
        hands = frame.Hands;

        for (int i = 0; i < hands.Count; i++)
        {
            Leap.Hand hand = hands[i];
            handProxy = (HandProxy)controller.GetGraphicsReps(hands[0].Id);
            // ?
        }
    }
}

If anyone has a better approach or can tell me what which step I have to take. Please let me know, thanks!

Edit: If anyone is wondering how I made the get function that I made in LeapHandController:

public HandRepresentation GetGraphicsReps(int key)
    {
        HandRepresentation result = null;

        if (graphicsReps.ContainsKey(key))
        {
            result = graphicsReps[key];
        }
        return result;
    }
