4 direction animation unity 2d

I’m doing a 2d game where the character walks in four directions but I do not know how to make him change the sprite depending on which direction he goes (sorry if it’s not well written I do not speak English)

this is the player script

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

public class Player : MonoBehaviour {

private Animator anim;
public Transform player;

public float speed;

// Use this for initialization
void Start () {
    anim = player.GetComponent<Animator>();
}

// Update is called once per frame
void Update () {
    Move();
}

void Move()
{
    if (Input.GetAxis("Horizontal") > 0)
    {
        transform.Translate(Vector2.right * speed * Time.deltaTime);
    }
    if (Input.GetAxis("Horizontal") < 0)
    {
        transform.Translate(Vector2.left * speed * Time.deltaTime);
    }
    if (Input.GetAxis("Vertical") > 0)
    {
        transform.Translate(Vector2.up * speed * Time.deltaTime);

    }
    if (Input.GetAxis("Vertical") < 0)
    {
        transform.Translate(Vector2.down * speed * Time.deltaTime);

    }
}

}

You need to change the rotation of the transform based on his movement, something like this:


 if (Input.GetAxis("Horizontal") > 0)
     {
         transform.Translate(Vector2.right * speed * Time.deltaTime);
         transform.rotation = Quaternion.Euler(0, 0, 90f);
     }

Animator.SetBool(“GoingUp”, true); // When he is going up
Animator.SetBool(“GoingDown”, true); // When he is going down, etc.
