You mean how can you make !chicken etpl say "ETPlayer is a chicken!" ?
If that is what you mean, I'm fairly sure you would need the command to be defined as follows:
command = chicken
exec = chat "[1?] is a chicken!"
desc = Call someone chicken
levels = 0 1 2 3 4 etc etcTo help you understand what the "[1?]" means - the 1 passes the 1st thing you type after !chicken, and the ? part tells silEnT MOD to look for a partial playername match..
So you could go even further and change the command to this..
command = insult
exec = chat "[1?] is a !"
desc = Insult somebody
levels = 0 1 2 3 4 etc etcAnd then do !insult etpl fool, and the server would then say "ETPlayer is a fool!"
