This is a pretty simple one that will show how many bot members are online

Save as MembersOnline.php in your modules folder, and use !membersonline on tells or raidchannel

<?
$membersOnline = new MembersOnline($bot);

$commands["tell"]["membersonline"] = &$membersOnline;
$commands["pgmsg"]["membersonline"] = &$membersOnline;


class MembersOnline
{
var $bot;
var $message;


function MembersOnline (&$bot)
{
$this -> bot = &$bot;
}

function tell($name, $msg)
{
$this -> bot -> send_tell($name, $this -> processCommand($name, $msg));
}

function pgmsg($name, $msg)
{
$this -> bot -> send_pgroup($this -> processCommand($name, $msg));
}


function processCommand($name, $msg)
{
if (preg_match("/^" . $this -> bot -> commpre . "membersonline$/i", $msg))
{
if ($this -> bot -> admin -> in_group($name, "leader") || $this -> bot -> admin -> in_group($name, "admin"))
{
$allonline = array_keys($this -> bot -> commands["tell"]["online"] -> guild);
$online = count($allonline);
return "There are <font color=#ffff00>$online</font> <botname> members online.";
}
}
}
}
?>

There's a much easier way of showing the online members, and to show an actual list.

Get the members from the DB, 1 by 1, and as you get, check if they are online, (which doesn't exactly need to be saved in buddylist), add 1 to a counter, make an array if you want to show all members.

If you understand that, it theoretically should work I'll try to do up an online list today and post.

I made a !memberslist to show all members of the bot, along with if they were online.

That piece Wanuarmi posted is just repetition as it's already a module for the bot :p
