Lens Flare Flash Using Intensity

Question

I need it so that my lens flare will flash when a key is pressed, then turns off when pressed again. I have got this script but it says that MissingFieldException: UnityEngine.LensFlare.intensity

 private var on = true;
 var timer =0.2;
  
 function Start () {
     while (true) {
         yield WaitForSeconds(0.08);
         LensFlare.intensity = !LensFlare.intensity;
         
 
     }
 }
 function Update(){
 
 if(Input.GetKeyDown("f2")){
 if(on){
 LensFlare.intensity =0;
 on = false;
 }
 else {
 LensFlare.intensity =1;
 on = true;
 }
 }
 }

The LensFlare is a component, so you have to get access to a specific LensFlare component on a specific object using GetComponent(). You cannot access a LensFlare through the class. In addition there is no 'intensity' variable on a LensFlare. There is a 'brightness' variable. That variable is a float, so you cannot use it the way you are trying to do in line 7. Here is a quick rewrite of your code. Attach it to the game object that has a LensFlare component.

 private var on = true;
 var timer = 0.2;
 var lensFlare : LensFlare;
  
 function Start () {
     lensFlare = GetComponent(LensFlare);
 
     while (true) {
         yield WaitForSeconds(0.08);
         lensFlare.brightness = 0.0;
         on = false;
         yield WaitForSeconds(0.08);
         lensFlare.brightness = 1.0;
         on = true;
     }
 }
 
 function Update() {
  
     if(Input.GetKeyDown("f2")){
         on = !on;
         lensFlare.brightness = (on) ? 1.0 : 0.0;
     }
 }
