hey at all, i need some help (once more)

i want a plane with a crosshair texture to be displayed when the enemy object is hitten by a raycast from the player ( if foundhit = true) it basically works but not continiously while its being hitten. it’s displayed for a short moment, then it disappears, then it is displayed again for a short moment (and so on) while the ray hits the enemy. seems it’s because of the update funct. certainly i tried to set it to : while(foundhit = true) and certainly unity stucked.
how to achiefe that it is displayed while! the ray hits ?
thx previously

here’s the code:
using UnityEngine;
using System.Collections;

public class Crosshair : MonoBehaviour {
	public Transform raytrf;
	public float raycastDist = 1000.0f;
	public string tagCheck = "Enemy";
	public bool foundHit;
	public bool checkAllTags = true;
	RaycastHit crosshair_hit;
	//private Renderer rend;
	public GameObject thisplane;

	// Use this for initialization
	void Start () 
	{
		//rend = GetComponent<Renderer> ();
		//rend.enabled = false;
	}
	
	// Update is called once per frame
	void Update () 
	{
		//bool foundHit = false;
		RaycastHit crosshair_hit = new RaycastHit();
		foundHit = Physics.Raycast(transform.position, transform.forward, out crosshair_hit, raycastDist);
		//Vector3 forward = raytrf.TransformDirection(Vector3.forward.normalized) * 1000;
		//Debug.DrawRay(raytrf.position,forward, Color.red);

		if (foundHit && checkAllTags && crosshair_hit.transform.tag != tagCheck)
		{
			foundHit = false;
			//rend.enabled = false;
		}
		if (!foundHit) 
		{
			thisplane.layer = LayerMask.NameToLayer ("Invisible");
			//rend.enabled = false;
			//Debug.Log("false");
		} 
		else 
		{
			if(foundHit) 
			{
				thisplane.layer = LayerMask.NameToLayer ("Default");
				//rend.enabled = true;
				//Debug.Log("hit");
			}
		}

	}

How about saving a reference to the hit object. In the raycast check, check the object reference for null. if it is, it’s the first time you raycasted something, save that. if it is not null, check if your raycast still the same. enable crosshair on first encounter and disable on first other encounter (different object or nothing hit)
