Hi,
I want to active a “sand” after few seconds, just to respawn it.
I know it’s a lot easier to do by making second script but I can’t ,because there will be more those GameObjects in scene.
Thanks in advance.

Here is my script:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;


[RequireComponent(typeof(Collider2D))]
public class Sand : MonoBehaviour
{


    Collider2D Collider;
    public GameObject sand;
    public float Time;
    public GameObject dust;




    void Start()
    {

        dust.SetActive(false);
        sand.SetActive(true);
        Collider = GetComponent<Collider2D>();
        Collider.enabled = true;
    }


    void OnTriggerEnter2D(Collider2D colider)
    {

        if (colider.gameObject.tag == "Player")
        {
            StartCoroutine("TimeIsTicking");
            ++ScoreMenager.HScore;
            Debug.Log("HighScore" + ScoreMenager.HScore);
            Collider.enabled = false;

        }
        
    }
    IEnumerator TimeIsTicking()
    {
        yield return new WaitForSeconds(Time);     
        dust.SetActive(true);
        yield return new WaitForSeconds(0.6f);
        sand.SetActive(false);
        dust.SetActive(false);

    }

Try to disable all componentes inside the object except the script and then enable them again
