How can I move a Kinematic Rigidbody2d along the x-axis?

Hey guys I’ve been searching for a while and couldn’t find a solution specifically for my needs. I’m working on a school project where my only current need is to make an object move horizontally through the x-axis, which is easy enough, but I cannot figure out how to make it work through the default values set in Unity, such as using the arrow keys and then setting A and D for the alternate negative-X and positive-X movements.

Here is my current code:

using UnityEngine;
using System.Collections;

public class PlayerController : MonoBehaviour
{
    public float speed = 5f;

    private Rigidbody2D rb2d;

    void Start()
    {
        rb2d = GetComponent<Rigidbody2D>();
    }
    void Update()
    {
        if (Input.GetKey(KeyCode.A))
        {
            transform.position += Vector3.left * speed * Time.deltaTime;
        }

        if (Input.GetKey(KeyCode. D))
        {
            transform.position += Vector3.right * speed * Time.deltaTime;
        }
    }
}

I tried using a code snippet I found from a tutorial on the Unity website but it was for using force and I couldn’t modify it for my needs. Unfortunately, I cannot use physics on my player object because it’s a kinematic rigidbody2d.

Could anyone provide insight on this?

You can use velocity to move horizontally or vertically.
rb2d.velocity = new Vector2(x,y);
// where x is the velocity in the x direction and y is the velocity in the y direction
