my post got somehow deleted
I asked bout this at besmella forum, and here's what Tonik replied:
What you want is certainly possible with QW262 (http://2wp.vei.ru/qw262/)
Disconnect has been porting some QW262 stuff to ezQuake so it might be possible there as well for all I know.
You can echo LEDs to the console by entering the chars directly. In FuhQuake you would press Ctrl+R/G/B. Not sure about ezQuake.
What I wanted to do: alter server msgs, such as "b1aze rides Term's rocket" to more efficient form: "Term $R$R b1aze" a.s.o. I like old servers msgs but on some official games it would be nice to have little more dullnes and effiency to see who dies and who's got the rl.
of course there should be different "term $R$R b1aze" msgs if term is an enemy/has rl/shaft/bores/quad/what ever.
This shouldnt be impossible, and I know there are some others wanting same thing.
So, bring your ideas fellas.
