    Okay so I've been working on this project for Oculus for a few weeks now and I've been working on the networking aspect of it. Networking works, but I have the problem where the Network Manager HUD wont show up because of the way its set up to display on the screen. I've already started on making my own HUD but I do not know how to set it up to behave exactly like the Network Manager HUD.

    Is the actual script for that out anywhere and if so where can I find it since Unity wont let me access it? Also is there just a way to change how the Manager HUD is displayed on the screen so I don't have to do this? If it was Screen Space Camera it would work perfectly, but its not so now I need to make my own.

    Okay so I can get it to create an Internet Match via only button commands but I get debug errors on my build saying my player id is -1 and it needs to be 0 or 1. When I try to join it just falls on its face.

    Im using the source code though so I don't know why its throwing me these issues since the normal Network Manager HUD works without any of these errors and the only thing I did was add in keycommands.

    Here is the code:
    Code (CSharp):
    1. #if ENABLE_UNET
    2.  
    3. namespace UnityEngine.Networking
    4. {
    5.     [AddComponentMenu("Network/NetworkManagerHUD")]
    6.     [RequireComponent(typeof(NetworkManager))]
    7.     [System.ComponentModel.EditorBrowsable(System.ComponentModel.EditorBrowsableState.Never)]
    8.     public class NetworkManagerHUD_Custom : MonoBehaviour
    9.     {
    10.         public NetworkManager manager;
    11.         [SerializeField] public bool showGUI = true;
    12.         [SerializeField] public int offsetX;
    13.         [SerializeField] public int offsetY;
    14.  
    15.         // Runtime variable
    16.         bool showServer = false;
    17.  
    18.         void Awake()
    19.         {
    20.             manager = GetComponent<NetworkManager>();
    21.         }
    22.  
    23.         void Update()
    24.         {
    25.             if (!showGUI)
    26.                 return;
    27.  
    28.             if (!NetworkClient.active && !NetworkServer.active && manager.matchMaker == null)
    29.             {
    30.                 if (Input.GetKeyDown(KeyCode.S))
    31.                 {
    32.                     manager.StartServer();
    33.                 }
    34.                 if (Input.GetKeyDown(KeyCode.H))
    35.                 {
    36.                     manager.StartHost();

    43.                 {
    44.                     manager.StartMatchMaker();
    45.                 }
    46.  
    47.                 /*if (Input.GetKeyDown(KeyCode.J))
    48.                 {
    49.                     manager.matchName = match.name;
    50.                     manager.matchSize = (uint)match.currentSize;
