I read that too when I went over the doc , I didnt think of the way i was using it as setting cvars , I thought setting cvars was considerred register_cvar . Ok ill try those commands out and see if they work . thanks alot guys + karma
EDIT ; ok i have on more question about the server_cmd function . can it be used to execute a restart server command , if it it can do i need to use rcon restart or just restart ? thanks again guys
