How to create Networking in Unity?
Hello everyone.
I am currently trying to build a prototype for a game a I am making and I am trying to get the Networking up and running but I am struggling to do so. I was hoping someone could help me. The thing I am struggling to do right now is connect to a Master Server. I have tried using Unity's, however I cannot connect to it. Then I tried downloading their Master Server code and trying it on my own computer, and I still cannot connect. I have looked up a lot of different tutorials and still have not found the answer. If anyone can help, it would be greatly appreciated. Also, I would like to try and get a basic prototype without using an plugins such as Photon. I will look into those later. Here is the code I have so far:
public class NetworkingScript : MonoBehaviour
{
public int ButtonWidthOffset;
public int ButtonHeightOffset;
public int WindowHorizontalOffset = 0;
public float WindowWidthModifier = 0.2f;
public int WindowVerticalOffset = 0;
public float WindowHeightModifier = 0.2f;
private string TestStatus = "Testing network connection capabilities.";
private string TestMessage = "Test in progress";
private string ShouldEnableNatMessage = "";
bool DoneTesting = false;
bool ProbingPublicIP = false;
int ServerPort = 9999;
ConnectionTesterStatus ConnectionTestResult = ConnectionTesterStatus.Undetermined;
bool UseNat = false;
private string ServerName = "", MaxPlayers = "0", PortNumber = "10101";
private Rect windowRect = new Rect(0, 0, 400, 400);
private List<HostData> hostData = new List<HostData>();
// Use this for initialization
void Awake ()
{
// MasterServer.ipAddress = my IP address
}
void OnGUI()
{
if(Network.peerType == NetworkPeerType.Disconnected)
{
GUILayout.Label("Server Name");
ServerName = GUILayout.TextField(ServerName);
GUILayout.Label("Port Number");
PortNumber = GUILayout.TextField(PortNumber);
GUILayout.Label("Max Player");
MaxPlayers = GUILayout.TextField(MaxPlayers);
if(GUI.Button(new Rect(Screen.width * 0.25f + ButtonWidthOffset, Screen.height * 0.4f + ButtonHeightOffset, 100f, 50f), "Create Game"))
{
try
{
Debug.Log("Server has been initiated");
InitializeServer(MaxPlayers, PortNumber, !Network.HavePublicAddress());
}
catch(Exception)
{
Debug.Log("Please type in numbers for port and max players");
}
}
if(GUI.Button(new Rect(Screen.width * 0.75f + ButtonWidthOffset, Screen.height * 0.8f + ButtonHeightOffset, 100f, 50), "Quit \"Game\""))
{
Application.Quit();
}
GUILayout.Window(0, new Rect(Screen.width / 2 + WindowHorizontalOffset, WindowVerticalOffset, Screen.width * WindowWidthModifier, Screen.height * WindowHeightModifier), WindowFunction, "Servers");
// GUILayout.Label("Current Status: " + TestStatus);
// GUILayout.Label("Test result : " + TestMessage);
// GUILayout.Label(ShouldEnableNatMessage);
// if (!DoneTesting)
// TestConnection();
}
}
