Hi I m new to unity C# coding i had taken help of Leap Motion tutorial to move the camera in and out according to the hand gesture but it is giving me
ArgumentOutOfRangeException : Argument is out of range.
Parameter name: index

code is below

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

public class ControlMove : MonoBehaviour {

Controller controller;
float HandPalmPitch;
float HandPalmYam;
float HandPalmRoll;
float HandWristRot;

// Use this for initialization
void Start () {

}

// Update is called once per frame
void Update () {
controller = new Controller ();
Frame frame = controller.Frame ();
List<Hand> hands = frame.Hands;
if (frame.Hands.Count > 0) {
Hand fristhand = hands [0];
}

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

HandWristRot = hands [0].WristPosition.Pitch;

Debug.Log ("Pitch :" + HandPalmPitch);
Debug.Log ("Roll :" + HandPalmRoll);
Debug.Log ("Yam :" + HandPalmYam);

//Move Object
//if (HandPalmYam > -2f && HandPalmYam < 3.5f) {
// transform.Translate (new Vector3 (0, 0, 1 * Time.deltaTime));
//} else if (HandPalmYam < -2.2f) {
// transform.Translate (new Vector3 (0, 0, -1 * Time.deltaTime));
//}
}
}

 

Please edit your post and use code tags - https://forum.unity.com/threads/using-code-tags-properly.143875/

The errors will be because the list is empty. You are creating a new instance of Frame and using the Hands list within it. So clearly the list Hands in Frame is also empty.
