You are not understanding the problem here. The name is fine in the
player file, but the mud keeps another array of the player's names that
is used for mailing and logging in, which is why they have to use the old
name to log in. I have implemented a change of name field in the do_set
command, which I will share below.
There was a bug (I don't know if it's been fixed yet) in circle that
still existed up to at least patch level 7 where new characters weren't
being properly added to the player_table array under odd and unlikely
circumstances, but I noticed the bug because when it did happen it broke
my renamer. I spend days looking for the error only to find that my
renamer's code was fine when I found the real bug.
I did send a report to Jeremy, but at first he confused it with
another bug that he had previously fixed and when I appealed to him again
(with instructions on how to break the mail system because of the bug) I
never got a responce (I assume he was just busy). Anyway, if you're using
pl7 or earlier, you'll need to fix the bug for certain, and possibly if
you're using a later version as well. I'll need to look up the details
about it because I fixed it so long ago that I forgot the relevant
function.
I implemented the renamer in a set field, and here is the code from
the big switch in do_set(). It is straight from my mud, so I haven't
modified it to look like it would be implemented in standard circle.
However I think that since my mud is a patch level 5 backbone you should
be able to figure it all out. If you have questions, feel free to ask.
