2D Character Movement (with RigidBody2D)

// This script enables simple, horizontal 2D character movement with a RigidBody2D.
// Ensure you have added a RigidBody2D component in the Inspector and have set its Body Type to Dynamic.
// GetAxisRaw makes the movement snappy, so the player instantly stops. If you want smoother movement, use GetAxis instead.

public class PlayerMovement : MonoBehaviour
{
    [SerializeField] float speed = 4f;

    float movement;

    void Start()
    {
        rb = GetComponent<Rigidbody2D>();
    }

    void Update()
    {
        movement = Input.GetAxisRaw("Horizontal") * speed; //GetAxis is smoother; GetAxisRaw is snappier    
    }

    {
        rb.MovePosition(rb.position + new Vector2(movement * Time.deltaTime, 0f));
