How to move my rigid body in the direction my model is facing.

Hello, Im new to Unity, iv been looking around for solutions and nothing seems to work. Sorry for the messy code, some of the solutions' variables i tried may be left still there.

I am trying to get my character to rotate using the horizontal axis inputs. So essentially W and S move my character forward and backwards while A and D would rotate the character to turn it slowly.

My character rotates but when i try to move forward, it is still stuck on the Z axis.

using UnityEngine; using System.Collections;

public class player : MonoBehaviour {

 public Animator anim;
 public Rigidbody rbody;
 public Transform unitychan;

 private float inputH;
 private float inputV;
 private bool run;
 private float turnspeed = 10;
 private Vector3 curLoc;
 private Vector3 prevLoc;
 private Vector3 newpos;


 // Use this for initialization
 void Start () {
     anim = GetComponent<Animator> ();
     rbody = GetComponent<Rigidbody> ();
     unitychan = GetComponent<Transform> ();
     run = false;
 }
 
 // Update is called once per frame
 void Update () {
 
     if (Input.GetKeyDown ("1")) {
         anim.Play("WAIT01",-1,0f);
     }
     if (Input.GetKeyDown ("2")) {
         anim.Play("WAIT02",-1,0f);
     }
     if (Input.GetKeyDown ("3")) {
         anim.Play("WAIT03",-1,0f);
     }
     if (Input.GetKeyDown ("4")) {
         anim.Play("WAIT04",-1,0f);
     }
     if (Input.GetMouseButtonDown (0)) {
         int n = Random.Range (0,2);
         if(n==0){
         anim.Play ("DAMAGED00",-1,0f);
         }
         else{
             anim.Play ("DAMAGED01",-1,0f);
         }
     }

     if (Input.GetKey (KeyCode.Space)) {
         anim.SetBool ("jump", true);
     } 
     else {
         anim.SetBool ("jump",false);
     }

     inputV = Input.GetAxis ("Vertical");
     inputH = Input.GetAxis ("Horizontal");
     //inputH = Input.GetAxis ("Horizontal");

     anim.SetFloat ("inputH", inputH);
     anim.SetFloat ("inputV", inputV);
     anim.SetBool ("run", run);

     float moveX = inputH * 20f * Time.deltaTime;

     float moveZ = inputV * 50f * Time.deltaTime;
     unitychan.Rotate (0, inputH * 100 * Time.deltaTime, 0);

     if (moveZ <= 0f) {
         moveX = 0f;
     } else if (run) {
         moveX*=3f;
         moveZ*=3f;
     }
     if (Input.GetKey (KeyCode.LeftShift) && moveZ!= 0) {
         run = true;
     }
     else {
         run = false;
     }      
 
     //rbody.velocity = new Vector3 (0f, 0f, moveZ) + transform.forward*moveZ;
     if (moveZ == 0f) {
         anim.SetBool ("stop", true);
     }
     else {
         anim.SetBool("stop",false);
     }
 }

}
