Hi, I’m getting this error: “NullReferenceException: Object reference not set to an instance of an object” on line 15 in my script, but I can’t see what’s the problem with the code. I’m trying to check if the var is true or false and change their values when pressing the letter L.

var myCheck : boolean = true;

function Update () {

	
	 if(myCheck == true){
	 	
	 	var myLight : Light  = gameObject.Find("light_test").GetComponent(Light);
	 		myLight.color = Color.green;
	 	
	}
	else
    {

	 		myLight.color = Color.red;

	}
	
	if(Input.GetKeyUp(KeyCode.L) && myCheck == true){
		myCheck = false;
	
	}
	else if(Input.GetKeyUp(KeyCode.L) && myCheck == false){
		myCheck = true;
	
	}

}

var myLight:GameObject;

drag your light on top of the new slot after saving the script

Thanks for the answers, but I found a way to make it work (maybe it’s not the best way), here’s the code: `#pragma strict

var myCheck : boolean = true;
var trueColor : Color = Color.green;
var falseColor : Color = Color.red;

function Update () {

 if(myCheck == true){
 	
 	var myLight : Light  = gameObject.Find("alvo_luz_certo").GetComponent(Light);
 		myLight.color = trueColor;
 	
}
else if (myCheck == false){

	gameObject.Find("alvo_luz_certo").GetComponent(Light).color = falseColor;

}

if(Input.GetKeyUp(KeyCode.L) && myCheck == true){
	myCheck = false;

}
else if(Input.GetKeyUp(KeyCode.L) && myCheck == false){
	myCheck = true;

}

}`
