Run animation click/touch to move problem

Hey i have obtained a script that allows a gameObject/player towards a touch point, which works fine without animations. However, when I try to implement animations into it, it does not run towards the clicked position. Instead, my player just run in linear direction and continues running without stop. I'm currently using the default ethan script and animations by Unity So yh here's the script

 using UnityEngine;
 using System.Collections;
 using UnityStandardAssets.CrossPlatformInput;
 
  public class TouchMove : MonoBehaviour
 {
    
     static Animator _animator;
     
     //flag to check if the user has tapped / clicked. 
     //Set to true on click. Reset to false on reaching destination
     private bool flag = false;
     //destination point
     private Vector3 endPoint;
     //alter this to change the speed of the movement of player / gameobject
     public float duration = 50.0f;
     //vertical position of the gameobject
     private float yAxis;
 
     void Start()
     {
         //save the y axis value of gameobject
         yAxis = gameObject.transform.position.y;
 
         _animator = gameObject.GetComponent<Animator>();
 
     }
 
     
 
     // Update is called once per frame
     void Update()
     {
 
         //check if the screen is touched / clicked   
         if ((Input.touchCount > 0 && Input.GetTouch(0).phase == TouchPhase.Began) || (Input.GetMouseButtonDown(0)))
         {
             //declare a variable of RaycastHit struct
             RaycastHit hit;
             //Create a Ray on the tapped / clicked position
             Ray ray;
             //for unity editor
 #if UNITY_EDITOR
             ray = Camera.main.ScreenPointToRay(Input.mousePosition);
             //for touch device
 #elif (UNITY_ANDROID || UNITY_IPHONE || UNITY_WP8)
    ray = Camera.main.ScreenPointToRay(Input.GetTouch(0).position);
 #endif
 
             //Check if the ray hits any collider
             if (Physics.Raycast(ray, out hit))
             {
                 //set a flag to indicate to move the gameobject
                 flag = true;
                 //save the click / tap position
                 endPoint = hit.point;
                 //as we do not want to change the y axis value based on touch position, reset it to original y axis value
                 endPoint.y = yAxis;
                 Debug.Log(endPoint);
             }
 
         }
         //check if the flag for movement is true and the current gameobject position is not same as the clicked / tapped position
         if (flag && !Mathf.Approximately(gameObject.transform.position.magnitude, endPoint.magnitude))
         { //&& !(V3Equal(transform.position, endPoint))){
           //move the gameobject to the desired position
 
            
             gameObject.transform.position = Vector3.MoveTowards(gameObject.transform.position, endPoint, 1 / (duration * (Vector3.Distance(gameObject.transform.position, endPoint))));
             _animator.SetBool("isRun", true);
 
             if (gameObject.transform.position == endPoint)
             {
                 _animator.SetBool("isRun", false);
             }
         }
         //set the movement indicator flag to false if the endPoint and current gameobject position are equal
         else if (flag && Mathf.Approximately(gameObject.transform.position.magnitude, endPoint.magnitude))
         {
             flag = false;
             Debug.Log("I am here");
         }
 
     }
 }
