Help with Unity + Leap hand tracking for custom gestures

[lb_net]

Hello,
i am new to unity and development. I want to create a game, where people can interact with a gameobject. For the interaction i created and defined some gestures. For all gestures except clapping, only one hand is required.
The code is working fine and there are no mistakes.But if I want to check all gesture both hands needed to be tracked. So i am not able to execute for example the TurnRadioOnGesture with only one hand. If i am switching the hands[1] to hands[0] the tracking for the ClapGesture is not working anymore - but the other one hand gestures.

I assume the access for the lefthand with hands[1] is not right but I can´t figure out a better way

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using Leap;
using Leap.Unity;

public class ControllMove : MonoBehaviour
{

    Controller controller;
    float HandPalmPitch;
    float HandPalmYaw;
    float HandPalmRoll;
    float HandWristRot;
    float HandDirectionPitch;
    float pinch;
    float HandPalmDirectionRoll;
    float LeftHand;
    float RightHand;
    float DistanceBetweenHands;
    Vector VectorHandPosRight;
    Vector VectorHandPosLeft;

    void Start()
    {

    }

    void Update()
    {
        controller = new Controller();
        Frame frame = controller.Frame();
        List<Hand> hands = frame.Hands;

            if (frame.Hands.Count > 0 )
            {
            Hand firstHand = hands[0];
            Hand secondHand = hands[1];
            }

        HandPalmPitch = hands[0].PalmNormal.Pitch;
        HandPalmRoll = hands[0].PalmNormal.Roll;
        HandPalmYaw = hands[0].PalmNormal.Yaw;

        VectorHandPosRight = hands[0].PalmPosition; //position right hand
        VectorHandPosLeft = hands[1].PalmPosition; // position left hand

        DistanceBetweenHands = VectorHandPosLeft.DistanceTo(VectorHandPosRight); //distance position between hands as float

        RightHand = hands[0].PalmNormal.Roll; //clap right hand
        LeftHand = hands[1].PalmNormal.Roll; // clap left hand

        HandPalmDirectionRoll = hands[0].Direction.Roll; //stroke

        pinch = hands[0].PinchStrength; //turn radio on


        //Debug.Log("RightHand: " + RightHand);

Curious if you have a solution for swiping from left to right? Your swipe seems to work great if I do right to left. But basically I would like to be able to handle both directions.

Thanks!
