How to detect RC login

[Arch_Angel]

Hello. I'm not new to GS2, but I am new to now trying to take it seriously in creating my own things and not just know a few commands and loops and such.

I am currently trying to make a message (or announcement) to echo on RC when a players RC is logged on.

I am using the control NPC to do this, and am wondering if it is possible. Right now I can only get a message to be triggered when the players client logs in. So I have something like.....

PHP Code:

function onCreated()
{
   this.staff = { "Arch_Angel", "Omaster", "littlekinky" }
}

function onActionPlayerOnline()
{
   if( pl.account in this.staff )
   {
      echo( "Welcome back " @pl.account );
   }
} 


Now this of course, is aimed to just send the message to RC when the players client logs in. Is there another function or something I can do that would recognize the RC instead?

Sorry if this is so simple, just trying to progress. Thanks ahead for any responses. Will rep accordingly.
