Where is GUI() called in this script?

Here is a Chat script I adapted from a C# script to JavaScript - and dragged it onto a Game Object. Also add a Network View to the Game Object!

It works!!

However I am new to JavaScript and I just wanted ask a couple of things

1. the function GUI() is called - but from where?
2. is the script ok for a first attempt? are there thing wrong with it?

Any help would be great.




// Proclaim the variables to be used at the start

var ChatHistoryArray;
var MessHist;

// when program starts assign some values to some of the variables
function Start()
{
scrollPosition =Vector2.zero;

natCapable = ConnectionTesterStatus.Undetermined;
}

// this function sets up the two interface windows and calls their respective functions
function OnGUI()
{
ChatWindowPos = GUI.Window (0, Rect(0, 0, 300, 400), ChatWindow, "Chat Window");
ConnWindowPos = GUI.Window(1, Rect(301, 0, 200, 280), ConnWindow, "Network Connection");
}

// RPC tag
@RPC

// this is the function that updates the Chat History array
function SendMess (MessHist : String)
{

// chat window function

// Connection window function
function ConnWindow (windowID : int)
{
GUILayout.Label(natCapable.ToString());

if (GUILayout.Button("Test NAT")) {

GUILayout.Label("PeerType: ");

if (MasterServer.PollHostList().length != 0) {
var hostData: HostData[] = MasterServer.PollHostList();
for (var i:int=0; i
GUILayout.Label("Game name: " + hostData.gameName);
GUILayout.Label("Players: " + hostData.connectedPlayers.ToString() + "/" + hostData.playerLimit.ToString());
if (GUILayout.Button("Connect") ){
Network.useNat = true;
MasterServer.RegisterHost("Name1", "Name2");
Network.Connect(hostData.ip, hostData.port);
}
}

}
}

// Updates the request for this chat prog on the MS
function Update()
{
MasterServer.RequestHostList("Name1");
}
