How to move something from point A to point B?

Hello, I’m pretty new at Unity and I’ve made a forest with a basic first person character and I have a light that has a halo on and I wanted to make that in the far far distance moving across the sky like a plane or helicoper.

All I’m trying to figure out is how to have it start moving when the game starts.

I’m sure you probably think I’m trolling because this is the stupidest question ever, but I really need to know

Add this to your light If you have any questions let me know and can I see your game when it is done?

#pragma strict
var moveSpeed : int = 5;
var Way : boolean = true;
var waitTime : int = 5;

function Update () {

if (Way == true){

MoveFoward ();

}

if (Way == false){

MoveBack ();

}

}

function MoveFoward (){

transform.Translate(Vector3.forward * moveSpeed * Time.deltaTime);

yield WaitForSeconds (waitTime);

Way = false;

}

function MoveBack (){

transform.Translate(Vector3.back * moveSpeed * Time.deltaTime);

yield WaitForSeconds (waitTime);

Way = true;

}
