BF2 rank script - how to show online status

Is there a way to get information about the online status of a player?

I was thinking of something showing if the pid queried is offline (not playing bf2) or online and then show which server he is playing on?

Would it be possible to use the "sv*-" parameter to find the server a player is on?

You can see the script in action here: http://bobforum.eyecatch.no/stats/?nick=Eyecatch

Re: BF2 rank script - how to show online status

you may be able to base whether they are currently playing off of the lbtl (last battle time) field given some threshold (15 minutes or something), and where they are playing off of the svr-0 field.

I haven't ever tried it myself, but in theory it should work.  otherwise you'd have to track all the servers online and query that data to see whether the player is playing and where.

Re: BF2 rank script - how to show online status

i already implemented the lbtl, but when i tried to add the svr-0 field to the query, i get an index out of bounds error.

on second thought, doesn't the per* parameter already include the svr-0?

if so, how should i edit the index.php?

Re: BF2 rank script - how to show online status

per* doesn't include the server that they're currently on.  you can tell whether they're online using lbtl (there's like a 20 minute difference between my web server and the time I see being reported for someone I know is online).

you should be able to tell what server they're on using svr-0, but you have to do additional queries to get that.  since gamespy only allows certain combinations of parameters in getplayerinfo, I'll have to log in and try to pull my stats, and see what query the svr- parameters show up in (and then add that to my bf2_player.php file).

I updated my bf2_player.php file to include all of the queries that I put in the comments of that file.  if you want to update the one you have and use this one, then you're more then welcome to.  this version allows either nick or pid to be passed in to the constructor of bf2_player.  if it finds the player, then is_valid will be true.

here's the code for that:

Code:

<?php

and I'll add the queries (if the game does them) later on tonight when I get home from work.

Re: BF2 rank script - how to show online status

well, I decompiled both the game client and server, and while svr-* is listed on the GetPlayerInfo columns page on bf2tech, it is not physically located in either binary.

I also pulled every available stat from in game client, and captured every network packet, and it never showed up, so my guess is that once upon a time, that parameter was allowed in a custom query to getplayerinfo, but is not allowed anymore.

as far as I can see it, your other options are, 1. poll every game server out there and store player info that you can query against, or 2. scrape game-monitor.com, or pay them for online services (like an xml feed that you can query against).

Re: BF2 rank script - how to show online status

Thank you for the help. I will just use the lbtl as you said first to tell if the player is online or not.
For a simple stats script, querying everything out there is too much.

Anyways, thanks for taking the time to help me!
