Script not showing variables in Inspector?

Hello everyone, I'm having some issues with a door i'd to have open/close in the latest version of Unity, I have a trigger and I have my door mesh, I'm copying this script online and on the video they have variables for the script, whereas I don't.. Any suggestions? * You'll also to forgive me, this is part of a University assignment and I'm completely new to coding, I'm normally using Unreal engine so I decided to switch it up with Unity


var door : GameObject;
var sound : AudioClip;
var text : GameObject;

function Start () {
door.SetActive(true);
text.SetActive(false);

}

function OnTriggerStay (col : Collider)
{
if(Input.GetKeyDown(KeyCode.E))
{
door.SetActive(false);
AudioSource.PlayClipAtPoint(sound, transform.position);
text.SetActive(false);

}
}

function OnTriggerExit (col : Collider)
{
text.SetActive(false);
}

function OnTriggerEnter (col : Collider)
{
text.SetActive(true);
}

Hey, I can't seem to reply to your comment but that isn't working either I'm afraid, I have 2 weeks to finish this project and right now anything to do with coding is giving me nightmares!

 

yeah i just checked it afterwards, myself coding in c#, and every variable is private at default, in unity/javascript everything is public by default.

only could think of that there's a compile error and therfore it's not displaying, but this you would have seen
