script to let player use a rocket launcher

Scripting
1

Hello,

I have a rocket launcher in my scene, and what I want is when the player gets close to it, he can press a button (like ‘E’) to use it.

And when He presses the button, a scope appears.

What exactly should I write in my script?

Thanks.

I already made the script for displaying “Press E to Use” :

    var distance:float;
    var Gui : GameObject;
    var Player : Transform;
    var DetectDistance = 15.0;
    function Update ()
    {
    	distance = Vector3.Distance(Player.position, transform.position);
    	if(distance < DetectDistance)
    	{
    		Show ();
    	}
    	if(distance > DetectDistance)
    	{
    		Hide (); 
    	} 
    }
    function Show ()
    {
    	Gui.active = true;
    }
    function Hide ()
    {
    	Gui.active = false;
    }

So, what is left is a script to show a scope(like Counter strike one) when E is pressed.

What should I write?
