applying animations on a top-down 2d game

i've recently started to learn coding alongside this project to make a top-down rpg,and i am having some trouble assigning my walking and idling animations to my character. first off i have used the following code to make the movement so i can make the movement grid based and disable diagonals and disable moving to a collider

 using System.Collections;
 using UnityEngine;
 
 class Movementt : MonoBehaviour {
     public float moveSpeed = 3f;
     public float runSpeed = 6f;
 
     private float gridSize = 1f;
     private bool allowDiagonals = false;
     private bool correctDiagonalSpeed = true;
     private Vector2 input;
     private bool isMoving = false;
     private Vector2 startPosition;
     private Vector2 endPosition;
     private float t;
     private float factor;
 
 
     public void Start ()
     {
 
         }
 
 
 
 
     public void FixedUpdate() {
         if (!isMoving) {
             input = new Vector2(Input.GetAxis("Horizontal"), Input.GetAxis("Vertical"));
             if (!allowDiagonals) {
                 if (Mathf.Abs(input.x) > Mathf.Abs(input.y)) {
                     input.y = 0;
                 } else {
                     input.x = 0;
                 }
             }
 
             
             if (input != Vector2.zero) {
                 StartCoroutine(move(transform));
             }
         }
     }
     
     public IEnumerator move(Transform transform) {
         isMoving = true;
 
         t = 0;
         
 
             
         
         if(allowDiagonals && correctDiagonalSpeed && input.x != 0 && input.y != 0) {
             factor = 0.7071f;
         } else {
             factor = 1f;
         }
         startPosition = rigidbody2D.transform.position;
         endPosition = new Vector2 (startPosition.x + System.Math.Sign (input.x) * gridSize,
                                    startPosition.y + System.Math.Sign (input.y) * gridSize);
         RaycastHit2D right = Physics2D.Raycast (startPosition, Vector2.right, 1f);
         RaycastHit2D left = Physics2D.Raycast (startPosition, -Vector2.right, 1f);
         RaycastHit2D up = Physics2D.Raycast (startPosition, Vector2.up, 1f);
         RaycastHit2D down = Physics2D.Raycast (startPosition, -Vector2.up, 1f);
 
 
         if (right.collider != null && endPosition.x > startPosition.x) {
                         endPosition = startPosition;
         }
         if (left.collider != null && endPosition.x < startPosition.x) {
             endPosition = startPosition;
         }
         if (up.collider != null && endPosition.y > startPosition.y) {
             endPosition = startPosition;
         }
         if (down.collider != null && endPosition.y < startPosition.y) {
             endPosition = startPosition;
         }
 
 
 
 
 
         while (t < 1f)
         {
                 if (Input.GetKey (KeyCode.LeftShift)) {
             t += Time.deltaTime * (runSpeed / gridSize) * factor;
                         }
         else {
                 t += Time.deltaTime * (moveSpeed/gridSize) * factor;
             }
             transform.position = Vector2.Lerp(startPosition, endPosition, t);
             yield return null;
         }
         
         isMoving = false;
         yield return 0;
     }
 
 }

but since my characters is 2 units long and i want it to raycast from the feet i added the character as a child entity with y=1,and added the following code to try and animate it

 using UnityEngine;
 using System.Collections;
 
 public class playeranimation : MonoBehaviour {
     Animator anim;
     private Vector2 input;
     // Use this for initialization
     private float compareX;
     private float compareY;
     void Start () {
         anim = GetComponent<Animator> ();
     }
     
     // Update is called once per frame
     void fixedUpdate () {
         input = new Vector2(Input.GetAxis("Horizontal"), Input.GetAxis("Vertical"));
         if (Mathf.Abs (input.x) > Mathf.Abs (input.y)) {
                         input.y = 0;
                 } else {
                         input.x = 0;
                 }
         compareX = input.x;
         compareY = input.y;
         if (compareX > 0) {
                         if (Input.GetKey (KeyCode.LeftShift)) {
                                 anim.SetFloat ("MoveDirection", 2);
                         } else {
                                 anim.SetFloat ("MoveDirection", 1);
                         }
 
                         anim.SetFloat ("IdleDirection", 2f);
                 }
         if (compareX < 0) {
             if (Input.GetKey (KeyCode.LeftShift)) {
                 anim.SetFloat ("MoveDirection", -2);
             } else {
                 anim.SetFloat ("MoveDirection", -1);
             }
             
             anim.SetFloat ("IdleDirection", 3f);
         }
         if (compareY > 0) {
             if (Input.GetKey (KeyCode.LeftShift)) {
                 anim.SetFloat ("MoveDirection", 4);
             } else {
                 anim.SetFloat ("MoveDirection", 3);
             }
             
             anim.SetFloat ("IdleDirection", 0f);
         }
         if (compareY < 0) {
             if (Input.GetKey (KeyCode.LeftShift)) {
                 anim.SetFloat ("MoveDirection", -4);
             } else {
                 anim.SetFloat ("MoveDirection", -3);
             }
             
             anim.SetFloat ("IdleDirection", 1f);
         }
         if (input == Vector2.zero) {
                         anim.SetFloat ("Movedirection", 0);
                 }
 
 
 
 
 
 
     }
 }

and although i set these values to the animations none play whatsoever
