Help with turn based Movement in a grid

Hello everyone, I’m new and I need some advice on how to implement the grid system movement using the mouse, a bit like in the series of Heroes of Might and Magic. I created the battlefield using this script that generates tiles:
Grid.js

public var tilePrefab: GameObject;
public var numberOfTiles: int = 10;
public var tilesPerRow: int = 4;
public var distanceBetweenTiles: float = 1.0;

 
function Start()
{
    CreateTiles();
}
 
function CreateTiles()
{
    var xOffset: float = 0.0;
    var zOffset: float = 0.0;
 
    for(var tilesCreated: int = 0; tilesCreated < numberOfTiles; tilesCreated += 1)
    {
        xOffset += distanceBetweenTiles;
         
        if(tilesCreated % tilesPerRow == 0)
        {
            zOffset += distanceBetweenTiles;
            xOffset = 0;
        }
     
        Instantiate(tilePrefab, Vector3(transform.position.x + xOffset, transform.position.y, transform.position.z + zOffset), transform.rotation);
    }
}

Then I created a script to give to an object, called Target, which basically allows you to move it into the “grid” using the mouse.
Target.cs

using UnityEngine;
using System.Collections;

public class Target : MonoBehaviour
{

	public bool selected = false;
	public float floorOffset = 1; 
	public float speed = 5;
	public float stopDistanceOffset = 0.5f;
	
	private Vector3 moveToDest = Vector3.zero;
	private bool selectedByClick = false;
	
	private void Update ()
	{
	
//		if (renderer.isVisible && Input.GetMouseButton(0))
//		{
//			if (!selectedByClick)
//			{
//				Vector3 camPos = Camera.mainCamera.WorldToScreenPoint(transform.position);
//				//camPos.y = Mouse.InvertMouseY(camPos.y);
//				//selected = Mouse.selection.Contains(camPos);
//			}
			
//			if (selected)
				renderer.material.color = Color.red;
//			else
				renderer.material.color = Color.white;
//		}
		
		if (selected && Input.GetMouseButtonDown(1))
		{
			Vector3 destination = Mouse.GetDestination();
			
			if (destination != Vector3.zero)
			{
				//gameObject.GetComponent<NavMeshAgent>().SetDestination(destination);
				
				moveToDest = destination;
				moveToDest.y += floorOffset;
			}
			
		}
		if (selected && Input.GetMouseButtonDown(0))
		{
			selected = false;

			
		}

		UpdateMove();
	}
	
	private void UpdateMove()
	{
		if (moveToDest != Vector3.zero && transform.position != moveToDest)
		{
			Vector3 direction = (moveToDest - transform.position).normalized;
			direction.y = 0;
			transform.rigidbody.velocity = direction * speed;
			
			if (Vector3.Distance(transform.position, moveToDest) < stopDistanceOffset)
				moveToDest = Vector3.zero;
		}
		else
			transform.rigidbody.velocity = Vector3.zero;
			
	}

	private void OnMouseDown()
	{
		selectedByClick = true;
		selected = true;
	}
	
	private void OnMouseUp()
	{
		if (selectedByClick)
			selected = true;
		
		selectedByClick = false;
	}

	
}

The only thing is that the movement appears to be “free”, not connected to the grid.

How can I do so that it is connected to the grid? So that the object moves per block ??

Thanks and sorry for my bad English
I hope I was clear enough

Hello! No, I gave up and bought the TBTK asset by SongGameDev! ;D
