gameobject.setactive not working for me

Hello. I'm new to unity and I'm trying to hide health bar when pause menu is open and show it again when pause menu is closed. Health bar is hiding when i open pause menu but it isn't showing up when i close pause menu. Thanks.

using System.Collections;

using System.Collections.Generic;

using UnityEngine;

using UnityEngine.UI;

public class HealthBar : MonoBehaviour

{

    public Slider slider;

    public Gradient gradient;

    public Image fill;

    public GameObject pause;

    public void SetMaxHealth(int health)

    {

        slider.maxValue = health;

        slider.value = health;

        fill.color = gradient.Evaluate(1f);

    }

    public void SetHealth(int health)

    {

        slider.value = health;

        fill.color = gradient.Evaluate(slider.normalizedValue);

    }

    public void Update()

    {

        if (pausemenu2.GameIsPaused)

        {

            gameObject.SetActive(false);

        }

        else

        {

            gameObject.SetActive(true);

        }

    }

}

 

It might be because you disable the object having this script.... When it's disabled, also this script is disabled.

 

Is there anything I can do or is there other way to hide this object

 

GetComponent(MeshRenderer).enabled = false;
(If you are trying to hide an object without disabling it completely).
