I was wondering if it is possible to call an argument string in an alias, for example:
alias servermsg "rcon ui_message" $arg
Ofcourse this doesn't work but ideally I would only have to type servermsg <something> in the console to have <something> relayed as a serverwide message.
cvar is a 'console variable', i.e. a variable accessible through the console. So if you type mycvarname in the console it would bring up the message myvalue--if it was set before hand.
There is also "getcvar" and you can see a list of cvars that are already in the game by typing "cvarlist" in the console.
