I am stuck on this for 2 days now, can anyone help me please. I am making a grid base dungeon explore game. The issue is when the player go to the next floor ( trigger next scene) and come back, all the enemies and items reappear in the scene. I was able to get my player stats working by using a static class, but I can’t do that for the enemy or pickup because some of them share the same script. What I tried so far is to store each gameobject in the hierarchy into a list to get their name, then assign a bool list to get the current status. So right now I am able to get all the game object that tag with the enemy on the console, and it does output a debug message that tells if the enemy should be destroy on the next load. I tried to set active(false) of the list or destroy the gameobejct in the list, both don’t work. What should I do next?
Below is what my game looks like and script.

using UnityEngine;

using System.Collections;

using System.Collections.Generic;

public class destroyonload : MonoBehaviour
{
// Start is called before the first frame update
public static destroyonload instance;

public static List<GameObject> mylist = new List<GameObject>();
List<GameObject> list1= new List<GameObject>();
public static List<bool> boollist = new List<bool>();
public static List<GameObject> itemlist;

void Awake()
{
    DontDestroyOnLoad(this);

    if(instance == null)
    {
        instance = this;
    }

     else
    {
      //Duplicate GameManager created every time the scene is loaded
      
      Destroy(gameObject);
    }       
    
    foreach (GameObject obj in Object.FindObjectsOfType(typeof(GameObject)))
        {     
            //obj.CompareTag("canbepickup")||
            if(obj.CompareTag("enemy")){
                Debug.Log(obj.name);
                list1.Add(obj);
                    if(Enemy.shoulddestroy == false){
                    Debug.Log("First time encounter" + obj);
                    boollist.Add(false);
                }

                else{
                    Debug.Log("the hit object should be destory" + obj);
                    boollist.Add(true);
                }
                //array2.AddRange(list1,boollist);
            }
        }

    itemlist.AddRange(list1);
}

void Start()
{
    if(itemlist!= null)
    {
        foreach(GameObject list in mylist){
            Debug.Log("attempt to destory list" + list);

            if(list.activeInHierarchy){
            list.SetActive(false);
            Debug.Log("attempt to set active false");
            }

            Debug.Log("done destory");
        }
        
        int i = 0;
        while(itemlist*!= null){*

int j =0;
for(j=i;j<itemlist.Count;j++)
{
if(boollist[j] ==true){
Destroy(itemlist*);*
}
}
i=i+1;
}

}

}
}
Enemy Script:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class Enemy : Character
{
public static bool shoulddestroy= false;
public int damageStrength;
void OnTriggerEnter2D(Collider2D other)
{
if (other.gameObject.CompareTag(“Player”)){
shoulddestroy = true;
print(“you should destory on next load”+ other.gameObject);
}

}
void OnTriggerExit2D(Collider2D other)
{
if (other.gameObject.CompareTag(“Player”)){

print(“im out”+ other.gameObject);
}

}

Do you mean you want to remove all item after reload scene? You can save your progress to save all progress. Fore example if you want to destroy and after reload the scene you do not want to see that item there then you need to save the progress.
