I need help with player animation.

alright so i am really new with coding and using unity, but i got a player movement script. the problem is that i dont know how to make animations when going left right up down and idle. im making a 2d topdown btw. here is the movement script i have:

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

public class NewController : MonoBehaviour { public float MoveSpeed = 5f; public Transform movePoint; public LayerMask StopMovement;

 void Start()
 {
     
     movePoint.parent = null;
 }

 // Update is called once per frame
 void Update()
 {
     transform.position = Vector3.MoveTowards(transform.position, movePoint.position, MoveSpeed * Time.deltaTime);
     
     if (Vector3.Distance(transform.position, movePoint.position) <= 0.05f)
     {



         if (Input.GetAxisRaw("Horizontal") > 0.5f || Input.GetAxisRaw("Horizontal") < -0.5f)
         {
             if (!Physics2D.OverlapCircle(movePoint.position + new Vector3(Input.GetAxisRaw("Horizontal"), 0f, 0f), 0.2f, StopMovement))
             {
                 
                 movePoint.position += new Vector3(Input.GetAxisRaw("Horizontal"), 0f, 0f);
                
             }
         }

         else if (Input.GetAxisRaw("Vertical") > 0.5f || Input.GetAxisRaw("Vertical") < -0.5f)
         {
             if (!Physics2D.OverlapCircle(movePoint.position + new Vector3(0f, Input.GetAxisRaw("Vertical"), 0f), 0.2f, StopMovement))
             {
                 
                 movePoint.position += new Vector3(0f, Input.GetAxisRaw("Vertical"), 0f);
             }
         }
         
     }
    
 }

}

Any help would be gladly appriciated!
