Granting privileges to players by SteamID?

Yo,

I'm trying to make a plugin that targets specific SteamID's of the connected players and give them priviligies. Sort of like admin or something similar.

How would I target their SteamID's directly?

 

player.userID is their "64bit" Steam ID i think.

So you could do:

Code:

if ( player.userID == AUserIDHere )
{
    //Do stuff
}

If you wanted to convert it back to a STEAM:1_blahblah you would have to reverse the 64bit method

Here is some PHP that does it which you could re-create in the plugin:
xPaw/SteamID.php - PHP - GitHub

However, why dont you just use the Permission Groups, they already use Steam ID's?
