Yes, it CAN be done.
I figured out the basic method with the help of the people at du moo
(moo.du.org). The system was first developed by Alex Stewart. I will
only give your the basic layout. The programming is up to you (that's
what they made ME do). Anyway... on with the show:
Problem: Every line that a user types in before login is treated as a
command. Therefore, we can't just do a read. Here's where we defeat that:
1) Change connect to accept 1-2 args. If 2, log the person in normally.
If 1 do the following:
turn echoing off with set_connection_option
add an element to a prop on $login called... let's say... con_waiting. The
list conatains the con_waiting is a list of lists (or a 2d array for).
The format is this: {{player#, args[1] (the req name)}, {#, name}...}
quit
2) change the $login:parse_command to check the following:
if the command doesn't match (it won't since it's the password) do this:
if the player # is in the list on $login.con_waiting then:
get the name
take the element off con_waiting
set echoing back on
and return: "connect <namefromconwaiting> <commandtobeparsed>"
if player# isn't in con_waiting return $bogus_command
that'll do it... any further questions can be asked of me directly at:
