Helicopter script error

I’m making a Unity helicopter using this tutorial

http://www.gotow.net/andrew/wordpress/?page_id=99

and I have a good script going:

    var main_Rotor_GameObject  : GameObject;
var tail_Rotor_GameObject  : GameObject;
var max_Rotor_Force  : float = 22241.1081;
var max_Rotor_Velocity  : float = 7200;
static var         rotor_Velocity  : float = 0.0;
private var  rotor_Rotation  : float = 0.0; 
var  max_tail_Rotor_Force  : float = 15000.0; 
var max_Tail_Rotor_Velocity  : float = 2200.0; 
private var  tail_Rotor_Velocity  : float = 0.0; 
private var  tail_Rotor_Rotation  : float = 0.0;
var  forward_Rotor_Torque_Multiplier  : float = 0.5;
var  sideways_Rotor_Torque_Multiplier : float = 0.5;
static var          main_Rotor_Active : boolean = true;
static var          tail_Rotor_Active : boolean = true;

function FixedUpdate () {
var torqueValue : Vector3;
var controlTorque : Vector3 = Vector3( 
Input.GetAxis( "Vertical" ) * forward_Rotor_Torque_Multiplier, 
1.0,
-Input.GetAxis( "Horizontal2" ) * sideways_Rotor_Torque_Multiplier
);
if ( main_Rotor_Active == true ) {
torqueValue += (controlTorque * max_Rotor_Force * rotor_Velocity);
rigidbody.AddRelativeForce( Vector3.up * max_Rotor_Force * rotor_Velocity );
}
if ( Vector3.Angle( Vector3.up, transform.up ) < 80 ) {
transform.rotation = Quaternion.Slerp( transform.rotation,
Quaternion.Euler( 0, transform.rotation.eulerAngles.y, 0 ),
Time.deltaTime * rotor_Velocity * 2 );
}
if ( tail_Rotor_Active == true ) {
torqueValue -= (Vector3.up * max_tail_Rotor_Force * tail_Rotor_Velocity);
}
rigidbody.AddRelativeTorque( torqueValue );
function Update () {
}
if ( main_Rotor_Active == true ) {
main_Rotor_GameObject.transform.rotation = transform.rotation * 
Quaternion.Euler( 0, 
rotor_Rotation,
0
);
}
if ( tail_Rotor_Active == true ) {
tail_Rotor_GameObject.transform.rotation = transform.rotation * 
Quaternion.Euler( tail_Rotor_Rotation,
0,
0
);
}
rotor_Rotation += max_Rotor_Velocity * rotor_Velocity * Time.deltaTime;
tail_Rotor_Rotation += max_Tail_Rotor_Velocity * rotor_Velocity * Time.deltaTime;
var hover_Rotor_Velocity = (rigidbody.mass * Mathf.Abs( Physics.gravity.y )
/ max_Rotor_Force);
var hover_Tail_Rotor_Velocity = (max_Rotor_Force * rotor_Velocity) 
/ max_tail_Rotor_Force;
if ( Input.GetAxis( "Vertical2" ) != 0.0 ) {
rotor_Velocity += Input.GetAxis( "Vertical2" ) * 0.001;
}else{
rotor_Velocity = Mathf.Lerp( rotor_Velocity, 
hover_Rotor_Velocity, 
Time.deltaTime * Time.deltaTime * 5
);
}
tail_Rotor_Velocity = hover_Tail_Rotor_Velocity - Input.GetAxis( "Horizontal" );
if ( rotor_Velocity > 1.0 ) {
rotor_Velocity = 1.0;
}else if ( rotor_Velocity < 0.0 ) {
rotor_Velocity = 0.0;
}
}

And the error console says “Assets/Scripts/Helicopter_Script.js(3,24): BCE0044: unexpected char: 0xFB02.”
I really dont know what that means so any help would be great thanks

Heh, 0xFB02 is a special character for a ligature of “fl”. And indeed, if you try to select just the “f” of “float” in line 3, you see you can’t select it without also selecting the “l”.

To answer your question, just delete the word “float” in line 3, and type it again.

EDIT: woops, all other "float"s have the same problem. Don’t copy the code out of the .pdf, just download the project.
