health decrease only once and stop player movement

Questions & Answers
1

i am trying to create a script that only triggers -1hp once when I enter the collider before the level restarts using timer but whenever I enter the collider twice before the level restarts I keep losing hp.

I tried using a Boolean and it didn’t work. I also tried setting the player movement speed to zero from my movement script so that he/she would stop, that didn’t work either.

any help is greatly appreciated. thank you

// this is my code below thanks

using System.Collections;

using System.Collections.Generic;

using UnityEngine;

using UnityEngine.SceneManagement;

public class death : MonoBehaviour

{

public bool one = false;

public static int health1 = 5;

public GameObject player2;

public bool healthchecker;

// Start is called before the first frame update
void Start()
{
    player2 = gameObject.transform.parent.gameObject;
    healthchecker = true;
}

// Update is called once per frame
void Update()
{

    health1 = PlayerPrefs.GetInt("Playerr");
}

private void OnTriggerEnter2D(Collider2D collision)
{

    if (collision.tag == "Player" && one == false && healthchecker == true)
    {
        healthchecker = false;
        StartCoroutine(dea());

        IEnumerator dea()
        {
            one = true;

            GameControlScript.health -= 1;

            yield return new WaitForSeconds(1);
            {

                SceneManager.LoadScene("level2.1");
            }
        }

     

    }
    else
    {
        healthchecker = true;
    }
}

}

Yeah sorry I realized that it keeps the healthchecker true whenever I enter the collider so that Boolean is basically useless…yes I am using rigidbody physics sorry I am new so I am really bad at coding thanks for the reply
