Как добавить управление 2D персонажем в прыжке на Unity. Вот скрипт(скажу сразу код не мой) на движения персонажа

public class PlayerControl : MonoBehaviour {
    public float maxSpeed = 10f;
    private bool isFacingRight = true;
    private Animator anim;
    
    private bool isGrounded = false;
    public Transform groundCheck;
    private float groundRadius = 0.2f;
    public LayerMask whatIsGround;

    private void Start()
    {
        anim = GetComponent<Animator>();
    }
    
    private void FixedUpdate()
    {
        isGrounded = Physics2D.OverlapCircle(groundCheck.position, groundRadius, whatIsGround); 
    anim.SetBool ("Ground", isGrounded);
    anim.SetFloat ("vSpeed", rigidbody2D.velocity.y);
    
    if (!isGrounded)
            return;
    
    float move = Input.GetAxisRaw("Horizontal");
        anim.SetFloat("Speed", Mathf.Abs(move));
        GetComponent<Rigidbody2D>().velocity = new Vector2(move * maxSpeed, GetComponent<Rigidbody2D>().velocity.y);
        if(move > 0 && !isFacingRight)
            Flip();
        else if (move < 0 && isFacingRight)
            Flip();
    }

    private void Update()
    {
        if (isGrounded && Input.GetKeyDown (KeyCode.W)) 
        {
            anim.SetBool("Ground", false);
            rigidbody2D.AddForce(new Vector2(0, 600));              
        }
    }


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