Why when changing some object position it's taking time like 3-5 seconds to change the object position ?

    private List<Material> materials = new List<Material>();
    private bool alreadyFading = false;

    // Start is called before the first frame update
    void Start()
    {
        foreach (Transform _transform in transform)
        {
            if (_transform.GetComponent<Renderer>() != null &&
                _transform.GetComponent<Renderer>().material.shader != null &&
                _transform.GetComponent<Renderer>().material.shader.name == "Custom/Teleport")
            {
                materials.Add(_transform.GetComponent<Renderer>().material);
            }
        }
    }

    private void OnTriggerEnter(Collider other)
    {
        if (other.tag == "Teleporter")
        {
            StartCoroutine(WaitBeforeGo(3));
        }
    }

    IEnumerator WaitBeforeGo(int TimeToWait)
    {
        yield return new WaitForSeconds(TimeToWait);

        if (!alreadyFading) StartCoroutine(Teleport(-3, 3, 5f, materials));
    }

    IEnumerator Teleport(float from, float to, float duration, List<Material> materials)
    {
        alreadyFading = true;

        for (int i = 0; i < materials.Count; i++)
        {
            var timePassed = 0f;
            while (timePassed < duration)
            {
                timePassed += Time.deltaTime;

                var factor = timePassed / duration;
                var value = Mathf.Lerp(from, to, factor);

                materials*.SetFloat("_DissolveAmount", value);*

yield return null;
}

materials*.SetFloat("DissolveAmount", to);
_}*

transform.position = teleporters[1].transform.position;
alreadyFading = false;
}
}

The problem is that it’s getting to the line :
transform.position = teleporters[1].transform.position;
but only after 3-5 seconds after the Teleporter Coroutine has finished.
and the change position should be part of the teleporting. so first in the while loop it’s making the teleporting effect and then change the object position to the next teleporter but when the Coroutine finished it’s taking more 3-5 seconds to the object to change position.
I can’t figure out why it’s not changing position at the time the Coroutine has finished ?

You do the “dissolve” to each material in series = each takes the 5 seconds… did you mean to do the “dissolve” in parallel? I mean like changing the placement of the for and while loops. At he moment if you have 2 materials it will take 10 seconds to teleport (+ the 3 seconds from the WaitBeforeGo)
