problem with scripting movement

Questions & Answers

Hey, so I’ve followed a guide by code monkey where he shows how to script jumping and movement.
All the jumping part is ok (although I had to change it a little to work, I don’t know why) but there is a problem with moving, it doesn’t do that at all.
using System;
using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class Payer : MonoBehaviour
{

Rigidbody2D rigid2d;
public Func<BoxCollider2D> bCollider2D;
float jumpVelocity = 50f;
public BoxCollider2D bCollider2d;
public RaycastHit2D raycastHit2d;
public LayerMask platformsLayerMask;
float moveSpeed = 40f;

public void Start()
{
    rigid2d = transform.GetComponent<Rigidbody2D>();
    bCollider2D = transform.GetComponent<BoxCollider2D>;

}

private void Update()
{
    if (isGrounded() && Input.GetKeyDown(KeyCode.Space))
    {

        rigid2d.velocity = Vector2.up * jumpVelocity;
    }
}
private bool isGrounded()
{
    RaycastHit2D raycastHit2d = Physics2D.BoxCast(bCollider2d.bounds.center, bCollider2d.bounds.size, 0f, Vector2.down, .1f, platformsLayerMask);
    Debug.Log(raycastHit2d.collider);
    return raycastHit2d.collider != null;
}

private void HandleMovement()
{
    
    if (Input.GetKeyDown(KeyCode.A))
    {
        rigid2d.velocity = new Vector2(-moveSpeed, rigid2d.velocity.y);

    } else
    {
        if (Input.GetKeyDown(KeyCode.D))
        {
            rigid2d.velocity = new Vector2(+moveSpeed, rigid2d.velocity.y);

        } else
        {//no keys pressed
            rigid2d.velocity = new Vector2(0, rigid2d.velocity.y);
        }
    }
}

}

Does anybody know what to do?

here is a link to yt channel if necessary, about 9:30 minute.

Edit: I forgot to add. Yes, my player is called Payer. I just thought it would be funny

You need to call the HandleMovement() method inside the Update () function. Otherwise the movement code is never called.
