How to pickup flashlight with "E" key ?

Hello, I’m Lucas and my question is simple… Well, maybe not so simple, if it was, I would not ask it here…

I have a script that make I pick up my flashlight WHEN I walk next/over it, I want it to pick up the flashlight when I press the E key, but I already tried everything that I know.

The code I use to PickUp the flashlight (also the batteries for the flashlight):

using UnityEngine;
using System.Collections;

public class Pickup : MonoBehaviour
{
public enum Item
{
Flashlight,
Battery
}

public Item item;

void OnTriggerEnter()
{
	if(item == Item.Flashlight)
	{
	Flashlight.HeadlightMount.SetActiveRecursively(false);
	Flashlight.HeadlightMount.active = true;
		
		HUD.HasFlashlight = true;
	}
	else
	
		HUD.BatteryCount++;
	
	Destroy(gameObject);
	}
	
	
	
}

I think I need to edit the “OnTriggerEnter” to something with the key, right ?

Change the OnTrigger function like this: (added a simple if statement)

void OnTriggerStay()
{
  if(Input.GetKey(KeyCode.E))  // checks if "E" was pressed on the keyboard
  {
    if(item == Item.Flashlight)
    {
       Flashlight.HeadlightMount.SetActiveRecursively(false);
       Flashlight.HeadlightMount.active = true;
       HUD.HasFlashlight = true;
    }
    else
    {
       HUD.BatteryCount++;
       Destroy(gameObject);
    }
  }
}
