Не работает скрипт на объекте в Unity

это сам код:

using UnityEngine;
public class NewBehaviourScript : MonoBehaviour
{
    public float maxspeed = 10f;
    private bool flipRight = true;
    void Update()
    {
        float move = Input.GetAxis("Horizontal");
        GetComponent<Rigidbody>().velocity = new Vector2(move * maxspeed, GetComponent<Rigidbody2D>().velocity.y);
        if (move > 0 && !flipRight)
        {
            Flip();
        }
        else if (move < 0 && flipRight)
        {
            Flip();
        }
    }

    private void Flip()
    {
        flipRight = !flipRight;
        Vector3 theScale = transform.localScale;
        theScale.x *= -1;
        transform.localScale = theScale;
    }
}
