== Introduction ==

There are many ways to implement an advert system in BF2. A good way would probably be to use the RCON interface. But another one that might be worth playing around with, is a solution where you create a dedicated ''advert port'' on the server, and send messages to it at will, using a suitable client.

== Server Code ==

The idea is to let the server listen on a port bound to the 'localhost' interface, and read messages off that port, and post them to the players. The socket does of course need to be non-blocking, or it will interfere with the server. But I have no idea if the solution is to use a timer, like this code does. But this at least shows the consept:

<pre>
import socket
import host
import bf2

port = 29600
addr = ('localhost',port)
bufsize = 1024

s = None
msgtimer = None

def init():
global s, msgtimer
print "Initializing the 'advert client' script."
s = socket.socket(socket.AF_INET,socket.SOCK_DGRAM)
s.setblocking(0)
s.bind(addr)
msgtimer = bf2.Timer(read,1,1)
msgtimer.setRecurring(1)

def read(data):
if not s: return
try:
msg, client = s.recvfrom(bufsize)
except:
return False
if msg:
host.rcon_invoke("game.sayAll \"" + str(msg) + "\"")
</pre>

== Client Code ==

The client can be as easy or complex as anyone wish. This is the simplest possible client:

<pre>
#!/usr/bin/env python import socket HOST = 'localhost' PORT = 29600 print "Creating client socket." s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM) print "Sending data to server." s.sendto("Hi. I'm an advert client sending data to the server.", (HOST,PORT)) print "Closing socket." s.close()
</pre>
