Animator Override Controller for NPC/ Overriding sprite animations

Hi!

I am currently working on a 2d rpg game. I have created a 'player' who can move about a space using the keyboard arrows (using gamesplusjames tutorial). The player's sprite has a walk animation that works. I used a player movement script and created an animator that uses blend trees for idle and walk animations.

Here's the script for player movement:

 using UnityEngine;
 using System.Collections;
 
 public class PlayerController : MonoBehaviour {
 
     public float moveSpeed;
 
     private Animator anim;
     private bool playerMoving;
     public Vector2 lastMove;
     private Rigidbody2D myRigidBody;
 
     private static bool playerExists;
 
     public bool canMove;
     // Use this for initialization
     void Start () {
         anim = GetComponent<Animator>();
         myRigidBody = GetComponent<Rigidbody2D>();
 
         if (!playerExists)
         {
             playerExists = true;
             DontDestroyOnLoad(transform.gameObject);
 
         } else
         {
             Destroy(gameObject);
         }
         canMove = true;
     }
     
     // Update is called once per frame
     void Update () {
         playerMoving = false;
         if (!canMove)
         {
             myRigidBody.velocity = Vector2.zero;
             return;
         }
         if (Input.GetAxisRaw("Horizontal") > 0.5f || Input.GetAxisRaw("Horizontal") < -0.5f)
         {
             //transform.Translate(new Vector3 ( Input.GetAxisRaw("Horizontal") * moveSpeed * Time.deltaTime, 0f, 0f ));
             myRigidBody.velocity = new Vector2(Input.GetAxisRaw("Horizontal") * moveSpeed, myRigidBody.velocity.y);
             playerMoving = true;
             lastMove = new Vector2(Input.GetAxisRaw("Horizontal"), 0f);
         }
         if (Input.GetAxisRaw("Vertical") > 0.5f || Input.GetAxisRaw("Vertical") < -0.5f)
         {
             //transform.Translate(new Vector3(0f, Input.GetAxisRaw("Vertical") * moveSpeed * Time.deltaTime,  0f));
             myRigidBody.velocity = new Vector2(myRigidBody.velocity.x, Input.GetAxisRaw("Vertical")* moveSpeed );
 
             playerMoving = true;
             lastMove = new Vector2(0f, Input.GetAxisRaw("Vertical"));
         }
         if(Input.GetAxisRaw("Horizontal") < 0.5f && Input.GetAxisRaw("Horizontal") > -0.5f)
         {
             myRigidBody.velocity = new Vector2(0f, myRigidBody.velocity.y);
         }
         if (Input.GetAxisRaw("Vertical") < 0.5f && Input.GetAxisRaw("Vertical") > -0.5f)
         {
             myRigidBody.velocity = new Vector2(myRigidBody.velocity.x, 0f);
         }
         anim.SetFloat("MoveX", Input.GetAxisRaw("Horizontal"));
         anim.SetFloat("MoveY", Input.GetAxisRaw("Vertical"));
         anim.SetBool("PlayerMoving", playerMoving);
         anim.SetFloat("LastMoveX", lastMove.x);
         anim.SetFloat("LastMoveY", lastMove.y);
         GetComponent<SpriteRenderer>().sortingOrder = Mathf.RoundToInt(transform.position.y * 100f) * -1;
     }
 }
 

Here is the script for npc movement:

 using UnityEngine;
 using System.Collections;
 
 public class StudentMovement : MonoBehaviour {
 
     public float moveSpeed;
     private Vector2 minWalkPoint;
     private Vector2 maxWalkPoint;
 
     private Rigidbody2D myRigidBody;
 
     public bool isWalking;
 
     public float walkTime;
     private float walkCounter;
     public float waitTime;
     private float waitCounter;
 
 
     private int WalkDirection;
 
     public Collider2D walkZone;
     private bool hasWalkZone;
 
     public bool cantMove;
     private DialogueManager theDM;
 
     private Animator anim;
     public Vector2 lastMove;
 
     // Use this for initialization
     void Start () {
         anim = GetComponent<Animator>();
         myRigidBody = GetComponent<Rigidbody2D>();
         theDM = FindObjectOfType<DialogueManager>();
 
         waitCounter = waitTime;
         walkCounter = walkTime;
 
         ChooseDirection();
         if (walkZone != null)
         {
             minWalkPoint = walkZone.bounds.min;
             maxWalkPoint = walkZone.bounds.max;
             hasWalkZone = true;
         }
         cantMove = true;
     }
     
     // Update is called once per frame
     void Update () {
         if (!theDM.dialogActive)
         {
             cantMove = true;
         }
         if (!cantMove)
         {
             myRigidBody.velocity = Vector2.zero;
             return;
         }
         if (isWalking)
         {
             walkCounter -= Time.deltaTime;
             if(walkCounter < 0)
             {
                 isWalking = false;
                 waitCounter = waitTime;
             }
 
             switch (WalkDirection)
             {
                 case 0:
                     
                     //moving the sprite in the aforementioned direction
                     myRigidBody.velocity = new Vector2(0, moveSpeed);
 
                     anim.SetFloat("MoveX", 1);
                     anim.SetFloat("MoveY", 0);
                     if (hasWalkZone && transform.position.y > maxWalkPoint.y)
                     {
                         isWalking = false;
                         waitCounter = waitTime;
                     }
                     break;
                 case 1:
                    
                     anim.SetFloat("MoveX", 0);
                     anim.SetFloat("MoveY", 1);
                     myRigidBody.velocity = new Vector2(moveSpeed, 0);
                     if (hasWalkZone && transform.position.x > maxWalkPoint.x)
                     {
                         isWalking = false;
                         waitCounter = waitTime;
                     }
                     break;
                 case 2:
                     myRigidBody.velocity = new Vector2(0, -moveSpeed);
                     anim.SetFloat("MoveX", -1);
                     anim.SetFloat("MoveY", 0);
                     if (hasWalkZone && transform.position.y < minWalkPoint.y)
                     {
                         isWalking = false;
                         waitCounter = waitTime;
                     }
                     break;
                 case 3:
                     myRigidBody.velocity = new Vector2(-moveSpeed, 0);
                     anim.SetFloat("MoveX", 0);
                     anim.SetFloat("MoveY", -1);
                     if (hasWalkZone && transform.position.x < minWalkPoint.x)
                     {
                         isWalking = false;
                         waitCounter = waitTime;
                     }
                     break;
             }
             
         }
         else
         {
             waitCounter -= Time.deltaTime;
             myRigidBody.velocity = Vector2.zero;
             if(waitCounter < 0)
             {
                 ChooseDirection();
             }
 
         }
         GetComponent<SpriteRenderer>().sortingOrder = Mathf.RoundToInt(transform.position.y * 100f) * -1;
     }
     public void ChooseDirection()
     {
         WalkDirection = Random.Range(0, 4);
         isWalking = true;
         walkCounter = walkTime;
     }
 }
 

Now to the issue, I made an npc that can randomly move around but there are no animations connected to this movement. I thought I could create an animator override controller for all future npcs and base it off of the animator for player movement. I was able to enter the npc related animations in the overrider and connect the animator to my npc but I still do not see any animations.

If someone could assist me or point me in the right direction it would be greatly appreciated.
