I've been doing this tutorial:
http://www.unitytutorials.com/video/290/muzzle-flash--raycasting--bullet-explosion1

and when I finished it worked fine. Now all of a sudden it wont work, can anyone tell me what's wrong with these scripts:

Code:

var muzzleFlash :GameObject;
var values:Array;
var angle :int;
var bullet :Rigidbody;
var speed :int;

function Start ()
{
values = new Array();
values.length = 6;
values[0] = 220;
values[1] = 400;
values[2] = 100;
values[3] = 340;
values[4] = 72;
values[5] = 612;

for(var value :int in values)
{
   angle = value;
}
}
function Update ()
{
if (Input.GetButtonDown("Fire1"))
{
   transform.Rotate(0,0,angle);
   var instantiatedFlash = Instantiate(muzzleFlash, this.transform.position, this.transform.rotation);
   var instantiatedBullet = Instantiate(bullet, this.transform.position, this.transform.rotation);
   instantiatedBullet.velocity = transform.TransformDirection(Vector3.forward * speed);
   instantiatedFlash.transform.Rotate(-90,0,0);
   Destroy(instantiatedFlash, .03);
}
}

and this one:

Code:

var explosion:Transform;
var point :Vector3;
var explosionRotation :Quaternion;

function Update()
{
var hit :RaycastHit;
var fwd : transform.TransformDirection(Vector3.forward);
if (Physics.Raycast(this.transform.position,fwd,hit,1))
{
   point = hit.point;
   explosionRotation = Quaternion.FromToRotation(Vector3.up, hit.normal);
   Explode();
}
}
function Explode()
{
Destroy(this.gameObject);
var instanExplosion = Instantiate(explosion, point, explosionRotation);
}

This error message always comes up when I try to play the second script, in the editor:

Quote:

Assets/Explosion.js(8,47): UCE0001: ';' expected. Insert a semicolon at the end.

I just can't seem to fix it; and now that the whole thing has stopped working, I have no idea.

When I try to fire nothing happens, nothing instantiates. I suspect it may be something to do with it not recognising the button press.

Thanks

Hello,

I *think* your error is on that line but the wording is throwing you off:

Code:

var fwd : transform.TransformDirection(Vector3.forward);

The : in JS says "this is of type" but you're actually creating an object there. I think what you want is:

Code:

var fwd = transform.TransformDirection(Vector3.forward);
