How to get all child objects back to its start position.

[Fifax]

Hi everyone!

I am developing AR app using Unity 2019.1.0f.2 and Vuforia SDK and I came across annoying problem.

I need to reset position of my main object (model of an camera) to its starting position. So I wrote simple functions to do that:

PositionReset.cs

private static PositionReset instance;

    public static PositionReset Instance
    {
        get { return instance ?? (instance = GameObject.FindObjectOfType(typeof(PositionReset)) as PositionReset); }
        
    }

    /// <summary>
    /// main 3D object instance
    /// </summary>
    public GameObject mainObject;

    /// <summary>
    /// hold original position of all objects
    /// </summary>
    private Dictionary<string,Vector3> startPosition = new Dictionary<string, Vector3>();


    public void Awake()
    {
        if (instance == null)
            instance = this;
    }

    // Start is called before the first frame update
    void Start()
    {

    }

    // Update is called once per frame
    void Update()
    {
        
    }

    public void ResetPosition()
    {
        mainObject = GameObject.Find("193.0-0 Ognioszczelna Kamera Cyfrowa typu OKA-1_C 1");

        foreach (Transform transform in mainObject.GetComponentsInChildren<Transform>())
        {

            Vector3 localPosition;
            if (startPosition.TryGetValue(transform.name, out localPosition))
            {
                Debug.Log("RESET: Name: " + transform.name + " Local position: " + localPosition);

                transform.position = localPosition;
                //transform.position.Set(localPosition.x,localPosition.y,localPosition.z);
            }

        }
}


public void GetStartPosition()
    {
        //startPosition 

        //Transform[] childTransform = GetComponentsInChildren<Transform>();
        mainObject = GameObject.Find("193.0-0 Ognioszczelna Kamera Cyfrowa typu OKA-1_C 1");

        if (startPosition.Count < 1)
        {
            foreach (Transform transform in mainObject.GetComponentsInChildren<Transform>())
            {
                Debug.Log("ADD, Name: " + transform.name + " Local position: " + transform.localPosition);
                startPosition.Add(transform.name, transform.position);


            }
        }
}

I use function GetStartPosition() on imagetarget detection in another class, and then with button click from UI want to reset position with function ResetPosition(). What I get in the end is that all objects end up in random places. What am I missing? How does Unity take the position of those objects? in my opinion they should come back to starting point that I grabbed with GetStartPosition().

Here are some screenshots from scene view. Starting point(which should be end point) and actual messed result.

I would appreciate any help.
Thanks,
Simon
