For those people who have echo on problem.
bind in userconfig.cfg
alias in aliases.cfg (if you dont have an aliases config, copy your userconfig.cfg rename it aliases.cfg, delete all text inside aliases.cfg and copy alias shown below into it, then add.... exec aliases.cfg at the bottom of your config.cfg file.)
//echo stop//
bind "f10" "roomtog"
//echostop//
alias "roomtog" "roomon"
alias roomon "room_type 1; d1; echo room type 1; d0; alias roomtog roomoff"
alias roomoff "room_type 0; d1; echo room type 0; d0; alias roomtog roomon"
alias "d0" "developer 0"
alias "d1" "developer 1"
You should note that developer 1 no longer outputs text to the top of the screen, but only to the console now.
Havnt got a clue mate i just found it trawling through some forums.... seems to work.
I mainly get echos in other peoples comms not the game play or is that onn their end even though every1s comms has an ecco on my side.
