[HELP] help with a knife code

I don't know if it's even possible, but I need a code that recognizes when you get stabbed. I thought about (self waittill("knifed"); ) which sounds stupid but is there a code that recognizes when you are being knifed? (need it for gungame ofc :P)

Thank in advance!!

huh i dont get it. when you get knifed youll see a symbol like this in the left bottom:

Killer (KnifeSymbol) Victim

I dont know what you mean else ?? explain. plz

I need a code that for example, after you get knifed, something happens

Example:

Knifed()
{
//here comes the code i need, the one that if I get knifed, somehting happens
}

Like I want to do that after I get knifed in gungame, I lose a level... How I do that?
