Hello I have this script for moving object on single click

using System;
using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class Pohyb : MonoBehaviour{

    private GameObject aktivny;
    private bool pohybuje_sa;
    private float sila, rychlost, krok;
    private float x, y, z;
    private float lavo, pravo, vpred, vzad;
    private Vector3 pozicia;
    private Vector3 doLava, doPrava, doPredu, doZadu;
    private Vector3 kurzor;

    void Start()
    {
        krok = 2.0f;
        sila = krok * 4;
        rychlost = sila * Time.deltaTime;
    }

    void Update()
    {
        RaycastHit hit;
        kurzor = Input.mousePosition;
        Ray ray = Camera.main.ScreenPointToRay(kurzor);

        if (Physics.Raycast(ray, out hit))
        {
            //Debug.Log("HITTING ALL");
            if (hit.collider.tag == "Movable")
            {
                //Debug.Log("HITTING TAGGED");
                if (Input.GetButtonDown("Fire1"))
                {
                    //Debug.Log("CLICKING TAGGED");

                    aktivny = hit.transform.gameObject;
                    pohybuje_sa = true;

                    x = aktivny.transform.position.x;
                    y = aktivny.transform.position.y;
                    z = aktivny.transform.position.z;

                    pozicia = new Vector3(x, y, z);

                    lavo = x + krok;
                    pravo = x - krok;
                    vpred = z - krok;
                    vzad = z + krok;

                    doLava = new Vector3(lavo, y, z);
                    doPrava = new Vector3(pravo, y, z);
                    doPredu = new Vector3(x, y, vpred);
                    doZadu = new Vector3(x, y, vzad);
                }
            }
        }

        if (pohybuje_sa)
        {
            if (Input.GetKeyDown(KeyCode.A))
            {
                //Debug.Log("going left");
                StartCoroutine(move(doLava));
            }
            else if (Input.GetKeyDown(KeyCode.D))
            {
                //Debug.Log("going right");
                StartCoroutine(move(doPrava));
            }
            else if (Input.GetKeyDown(KeyCode.W))
            {
                //Debug.Log("going forward");
                StartCoroutine(move(doPredu));
            }
            else if (Input.GetKeyDown(KeyCode.S))
            {
                //Debug.Log("going back");
                StartCoroutine(move(doZadu));
            }
        }
    }

    IEnumerator move(Vector3 ciel)
    {
        while(true)
        {
            float distance = Vector3.Distance(pozicia, ciel);

            if (distance > 0.0f)
            {
                //Debug.Log("Object moving from " + position + " to " + target);
                pozicia = Vector3.MoveTowards(aktivny.transform.position, ciel, rychlost);
                aktivny.transform.position = pozicia;

                x = aktivny.transform.position.x;
                y = aktivny.transform.position.y;
                z = aktivny.transform.position.z;

                pozicia = new Vector3(x, y, z);

                lavo = x + krok;
                pravo = x - krok;
                vpred = z - krok;
                vzad = z + krok;

                doLava = new Vector3(lavo, y, z);
                doPrava = new Vector3(pravo, y, z);
                doPredu = new Vector3(x, y, vpred);
                doZadu = new Vector3(x, y, vzad);

                pohybuje_sa = false;
                yield return null;
            }
            else
            {
                pohybuje_sa = true;
                break;
            }
        }
    }
}

And it’s working fine but the object gets stuck in wall collider if I move it through wall.
How to fix it ?

Is it because of Vector3.MoveTowards ?
And if yes what is good alternative ?

If you need it to stop when it hits a wall, you need to use physics. Add a rigidbody and collider to your object, and instead of using MoveTowards, set the velocity to (target - position).normalized * speed. (You may want to disable gravity, freeze rotation, and tweak other properties of the rigidbody as well).
