Hi!
How can I create a list, which shows me the opened gameservers in lan like in cs?
I don't need any code, I only want to know how it should be done...
Thanks for your answers!

You would need to have a server to hold a list of all of the opened gameservers and every time a gameserver is opened, the program would have to send it's information to the central server.

This information could include IP Address, Game Server Name, number of players, and ping

That wouldn't work, as you can't use a hardcoded IP if the software must work on any LAN (you don't know what IPs are used inside the LAN, for server and clients).

I don't know the details, but I think it's possible to broadcast something to every computer on a LAN. So you can use a certain port to send out a message to all computers on the LAN and see which ones respond.

This is not built into 3dgs, so you would have to do plugin programming.

What does a 'central server' mean? I think only the same scripts can be connected as a server or client when they run in network, so how can they connect to a 'central server'? Can anyone explain this to me? Thanks!

they way to do it is via udp broadcast.

if you want to request a list, send a udp broadcast packet to the network called 'request'. the servers wich listen get the broadcast 'request' and immidiately or after a small delay, broadcast their information 'myserverip:port,map,players,freeslots...' back to everyone.
this way the client that send the request can again listen for the serverinformation and fill the list.

i doubt this is possible with a6, maybe it works with a7 if you include sockets.h if not you will have to write a .dll or use an external starter program for this purpose.

correct me if iam wrong...

Ok thanks for that informations.
So I need a plugin which can send/receive such a udp broadcast?
Is there already one out there or do I have to write it?

Dark_Samurai

Do I need c# for such a plugin or can it be written in c++?
Is it much effort to write such a plugin?
Do you know any good toturials for writing such a udp broadcasts?
Thanks!

allowing only one game per lan is no option for you?

Hi Dark_Samurai,

einen einzelnen server im lan (broadcasting) findet GSTNet so:

Code:

---

  GSTNet_StartClient("255.255.255.255",2300,-0.1);

---

bei mehreren servern ist mehr aufwand beim nachrichten handling zwischen dem client und den servern nötig. z.B.
Code:

---

  GSTNet_ClientSend(0, GetServerProperties, ""); // request must be handled on server side

---

nach auswahl des richtigen servers muß der client gestopt werden und mit der server ip gestartet werden
Code:

---

  GSTNet_Disconnect(0);  
  wait(-0.5);
  GSTNet_StartClient(sChoosenServerIP,2300,-0.1);
