On the game server - creating a text file with a list of current players

I want to create a text file with a list of current players. This will all be done outside the game on the windows server. I have never used UE3 API so I am a noob.

I'm actually interested in seeing how this could be done.

My google searching only leaves me more confused and I was wondering if anyone has done something similar to this.

    You need to use the A2S protocol (https://developer.valvesoftware.com/wiki/Server_queries) to query players from the server.

    I think I've seen you mention Python in the past. This is what you really want:

    You'll need to know your server's IP and query port (*not* 8777, in the 27000s). Throw them in where "server" is assigned. Set up the output however you want and you're done.
    import valve.source.a2s
        server = valve.source.a2s.ServerQuerier(address=('', 27020), timeout = 5.0)
        info = server.info()
        players = server.players()
        print "{player_count}/{max_players} {server_name}".format(**info)
        for player in sorted(players["players"],
                             key=lambda p: p["score"], reverse=True):
            print "{score} {name}".format(**player)
    except valve.source.a2s.NoResponseError:
        print "Master server request timed out!"

    Note: The AA Devs prepend [T0], [T1], and [T-1] to each player's name in the query response. [T-1] is spectators, the other two are alpha and bravo teams (or possibly attack & defense, see if they switch at the half). You may want to strip those depending on what you want out of this project.

    Finding the query port, if not known, is easily done via the Steam web APIs. Search an IP via
    and the response will look like this:
    		>>>		"addr": "",  <<< Query port
    				"gmsindex": 65534,
    				"appid": 203290,
    				"gamedir": "aa4game",
    				"region": -1,
    				"secure": false,
    				"lan": false,
    				"gameport": 7778,
    				"specport": 0
