script saying Index was out of range. Must be non-negative and less than the size of collection

[ca_ka_studio]

Hey so for my game this script is for finger movement, for some reason its giving this error : blob:https://photos.onedrive.com/e7947052-0402-48ce-b44b-7fc58bff44f0

public enum HandTypeLeft

    Left
}

public class XRHandL : MonoBehaviour
{
    public HandTypeLeft handType;
    public float thumbMoveSpeed = 0.1f;

    private Animator animator;
    private InputDevice inputDevice;

    private float pose4Value;
    private float pose5Value;
    private float pose6Value;
    public PhotonView view;

    // Start is called before the first frame update
    void Start()
    {
        animator = GetComponent<Animator>();
        inputDevice = GetInputDevice();
    }

    // Update is called once per frame
    void Update()
    {
        if (view.IsMine)
        {
            AnimateHand();
        }
    }

    InputDevice GetInputDevice()
    {
        InputDeviceCharacteristics controllerCharacteristic = InputDeviceCharacteristics.HeldInHand | InputDeviceCharacteristics.Controller;

        if (handType == HandTypeLeft.Left)
        {
            controllerCharacteristic = controllerCharacteristic | InputDeviceCharacteristics.Left;
        }
        else
        {
            controllerCharacteristic = controllerCharacteristic | InputDeviceCharacteristics.Right;
        }

        List<InputDevice> inputDevices = new List<InputDevice>();
        InputDevices.GetDevicesWithCharacteristics(controllerCharacteristic, inputDevices);

        return inputDevices[0];
    }

    void AnimateHand()
    {
        inputDevice.TryGetFeatureValue(CommonUsages.trigger, out pose4Value);
        inputDevice.TryGetFeatureValue(CommonUsages.grip, out pose5Value);

        inputDevice.TryGetFeatureValue(CommonUsages.primaryTouch, out bool primaryTouched);
        inputDevice.TryGetFeatureValue(CommonUsages.secondaryTouch, out bool secondaryTouched);

        if (primaryTouched || secondaryTouched)
        {
            pose6Value += thumbMoveSpeed;
        }
        else
        {
            pose6Value -= thumbMoveSpeed;
        }

        pose6Value = Mathf.Clamp(pose6Value, 0, 1);

        animator.SetFloat("pose4", pose4Value);
        animator.SetFloat("pose5", pose5Value);
        animator.SetFloat("pose6", pose6Value);
    }
}

Here are some notes on IndexOutOfRangeException and ArgumentOutOfRangeException:

http://plbm.com/?p=236

Steps to success:

• find which collection it is and what line of code accesses it <— (critical first step!)
• find out why it has fewer items than you expect
• fix whatever logic is making the indexing value exceed the collection size

Remember also:

• a collection with ZERO elements cannot be indexed at all: it is empty (as Arachnid notes above!)
• you might have more than one instance of this script in your scene/prefab
• the collection may be used in more than one location in the code
• indices start at ZERO (0) and go to the count / length minus 1.

This means with three (3) elements in your collection, they are numbered 0, 1, and 2 only.
