Server Side IP and Port Setting Example

Hi Guys,

New to Unity and I've currently written the below c# script to handle getting the input of an IP and Port on the command line and then starting my host only server using this details.

I'm sharing both for re-use and to ask for feedback on if this is a good way to do this or weather there is a cleaner/different way?

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using UnityEngine.Networking;
5. using UnityEngine.UI;
6.  
7. public class ServerCode : NetworkBehaviour {
8.  
9.     string[] args = System.Environment.GetCommandLineArgs();
10.     string serverPort = "7777";
11.     string serverIP = "127.0.0.1";
12.  
13.     // Use this for initialization
14.     void Start()
15.     {
16.         for (int i = 0; i < args.Length; i++)
17.         {
18.             if (args[i] == "-port")
19.             {
20.                 serverPort = args[i + 1];
21.             }
22.             if (args[i] == "-ip")
23.             {
24.                 serverIP = args[i + 1];
25.             }
26.         }
27.          
28.         if (System.Array.IndexOf (args, "-server") >= 0) {
29.  
30.             NetworkManager.singleton.networkPort = int.Parse(serverPort);
31.             NetworkManager.singleton.serverBindAddress = serverIP;
32.             NetworkManager.singleton.serverBindToIP = true;
33.             NetworkManager.singleton.StartServer ();
34.         } else {
35.             //Debug.Log("You didn't start a server this time!");
36.             //Application.Quit ();
37.         }
38.          
39.     }
40.      
41. }

Currently the way I launch this is:

Code (Boo):

1. GameProject.exe -batchmode -nographics -server -ip 192.168.0.2 -port 1234

 

If it's works and it's good enough - then it's ok.

One thing though - don't use == comparison for strings, use .Equals instead;
Also, hard coded values can be put into consts, or statics in a separate file, but that's just my preferences.
