How to all GameObjects in array or 2 objects collide with 1 object at the same time

I don’t know how to put this and it’s the middle of the night here and i’m tired lol

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

public class LeverMove : MonoBehaviour
{
    public Animator LeverAnim;
    public DoorScript door;

    public GameObject[] Players;
    void Update()
    {
        Players = GameObject.FindGameObjectsWithTag("Player");
    }

    private void OnTriggerStay2D(Collider2D collision)
    {
        if (Players[0 & 1] && Input.GetKey(KeyCode.Q))
        {
            LeverAnim.SetTrigger("LeverMoves");
            door.DoorOpen();
        }
        else
        {
            return;
        }
         
    }
}

so this is my code and what I wanna achieve is I want the players to all be (or only 2 of them)
be at a single trigger at the same time and whilst that’s happening the player should be able to press a key for the command to execute, anyone know how I can achieve this, Thanks!

You should use OnTriggerEnter and OnTriggerExit, to keep game objects in a list, then compare the lists for similar items. For example:

public GameObject[] Players;
public List<GameObject> PlayersInTrigger;

void OnTriggerEnter2D(Collider2D collision)
{
     PlayersInTrigger.Add(collision.gameObject);
}

void OnTriggerExit2D(Collider2D collision)
{
     PlayersInTrigger.Remove(collision.gameObject);
}

void Update()
{
     foreach (var player in Players)
     {
          if (!PlayersInTrigger.Contains(player))
              return;
     }

     // If code reaches this spot, all the players are in the trigger
}

If your trigger is more simple, like a sphere or box collider, use Physics2D.OverlapCircleAll, (which returns all colliders within a circle trigger of said radius), and check if each player is in that array of colliders. If so, they are in the trigger. Hope that helps @yousifalsewaidi
