function Awake() {

if (havemaster == true){ if (FindObjectOfType(ConnectGuiMasterServer)) this.enabled = false; } }

function OnGUI () { GUILayout.Space(10);

GUILayout.BeginHorizontal(); GUILayout.Space(10); if (Network.peerType == NetworkPeerType.Disconnected) { GUILayout.BeginVertical(); if (GUILayout.Button ("Connect")) { Network.useNat = useNAT; Network.Connect(remoteIP, remotePort); } if (GUILayout.Button ("Start Server")) { Network.useNat = useNAT; Network.InitializeServer(32, listenPort); // Notify our objects that the level and the network is ready for (var go in FindObjectsOfType(GameObject)) go.SendMessage("OnNetworkLoadedLevel", SendMessageOptions.DontRequireReceiver); } GUILayout.EndVertical(); remoteIP = GUILayout.TextField(remoteIP, GUILayout.MinWidth(100)); remotePort = parseInt(GUILayout.TextField(remotePort.ToString())); } else { if (GUILayout.Button ("Disconnect")) { Network.Disconnect(200); } }

GUILayout.FlexibleSpace(); GUILayout.EndHorizontal();

}

function OnConnectedToServer() { // Notify our objects that the level and the network is ready for (var go in FindObjectsOfType(GameObject)) go.SendMessage("OnNetworkLoadedLevel", SendMessageOptions.DontRequireReceiver);
}

function OnDisconnectedFromServer () { if (this.enabled != false) Application.LoadLevel(Application.loadedLevel); else FindObjectOfType(NetworkLevelLoad).OnDisconnectedFromServer(); }_________
