i have a script that allows a player to jump but only three times and then they can no longer jump but i want to be able to reset this number back to three if they hit a certain block but everything i’ve tried doesn’t work, anyone have any ideas?

jump script:

using UnityEngine;
using System.Collections;

[RequireComponent(typeof(Rigidbody))]
public class PlayerController : MonoBehaviour
{
public Vector3 jump;
public float jumpForce = 12.0f;
public int JumpsUsed = 0;
public int JumpsAll = 3;
public GameObject sfxSource;

public bool isGrounded;
Rigidbody rb;
void Start()
{
    rb = GetComponent<Rigidbody>();
    jump = new Vector3(0.0f, 12.0f, 0.0f);
    sfxSource = GameObject.Find("SFXsource");
}

void OnCollisionStay()
{
    isGrounded = true;
}

void Update()
{
    if (Input.GetKeyDown(KeyCode.UpArrow) && isGrounded && JumpsUsed < 3)
    {
        JumpsUsed ++;

        rb.AddForce(jump * jumpForce, ForceMode.Impulse);
        isGrounded = false;
        sfxSource.GetComponent<soundManager>().PlayJumpSound();
    }

    if (Input.GetKeyDown(KeyCode.UpArrow) && isGrounded && JumpsUsed > 3)
    {
        return;
    }
}

}

Try something like this

void OnCollisionEnter(Collision collision)
    {
        if(collision.gameObject.tag == BLOCKTAG)
        {
            JumpsUsed = 3;
        }
    }
