Script to animation and movement of 2d player

Question

Hi ! I new to game development and I found a tutorial for a script for movement of 2d player, I copied it, my animation works but my player doesn't move, I try to fix it. So this is the original script :

using UnityEngine; using System.Collections;

public class Playermovement : MonoBehaviour {

 Rigidbody2D rbody;
 Animator anim;

 // Use this for initialization
 void Start () {

     rbody = GetComponent<Rigidbody2D> ();
     anim = GetComponent<Animator> ();

}

 // Update is called once per frame
 void Update () {

     Vector2 movement_vector = new Vector2(Input.GetAxisRaw("Horizontal"), Input.GetAxisRaw("Vertical"));

     if (movement_vector != Vector2.zero) {
         anim.SetBool ("iswalking", true);
         anim.SetFloat ("Input_x", movement_vector.x);
         anim.SetFloat ("Input_y", movement_vector.y);
     }
     else {
         anim.SetBool ("iswalking", false);
         }
     rbody.MovePosition (rbody.position + movement_vector * Time.deltaTime);
     }
 }

This is the link to the tutorial : https://www.youtube.com/watch?v=XZDjkQ8wEd0&list=PL_4rJ_acBNMH3SExL3yIOzaqj5IP5CJLC∈dex=4

and I try to fix it with replace void Update by void FixedUpdate as explained comments

Finally, watching other script and trying, I fix my script. I thank you for trying to help me. So this is the new script with correction for those who have the same problem:

 using UnityEngine;
 using System.Collections;
 
 public class Playermovement : MonoBehaviour {
 
     public float speed = 18;
     Rigidbody2D rbody;
     Animator anim;
 
     // Use this for initialization
     void Start () {
 
         rbody = GetComponent<Rigidbody2D> ();
         anim = GetComponent<Animator> ();
 
     
     }
 
     void FixedUpdate () {
 
         Vector2 movement_vector = new Vector2(Input.GetAxisRaw("Horizontal"), Input.GetAxisRaw("Vertical"))*speed* Time.fixedDeltaTime;
 
         if (movement_vector != Vector2.zero) {
             anim.SetBool ("iswalking", true);
             anim.SetFloat ("Input_x", movement_vector.x);
             anim.SetFloat ("Input_y", movement_vector.y);
         }
         else {
             anim.SetBool ("iswalking", false);
         }
         rbody.MovePosition (rbody.position + movement_vector);
         }
     }
