My character is flipping but not moving?

using UnityEngine; using System.Collections;

public class playerController : MonoBehaviour {

 private Animator playerAnim;
 private Rigidbody2D playerBody;


 public float maxSpeed;
 bool grounded;
 bool isFacingRight;

 // Use this for initialization
 void Start () {
     grounded = true;
     playerBody = GetComponent<Rigidbody2D> ();
     playerAnim = GetComponent<Animator>();
 }

 // Update is called once per frame
 void Update () {
     
     float moveInp = Input.GetAxis("Horizontal");
     playerBody.velocity = new Vector2 (moveInp * maxSpeed, playerBody.velocity.y);

         if (moveInp > 0) {
             gameObject.transform.rotation = Quaternion.Euler (new Vector3 (0, 0, 0));
             isFacingRight = true;
         } else if (moveInp < 0) {
             gameObject.transform.rotation = Quaternion.Euler (new Vector3 (0, 180, 0));
             isFacingRight = false;    
         }


 }
