Banning Problem with a list

Code:
ADMIN
    verb
        Ban(mob/M as null|anything in players)
            world << "<center>[M] was banned by [usr.key]!</center>"
            banned += M
            M.Logout()


Problem description:
I get a runtime error:
runtime error: Cannot execute null.Logout().
proc name: Ban (/ADMIN/verb/Ban)
usr: Hi1 (/mob)
src: Hi1 (/mob)
call stack:
Hi1 (/mob): Ban(null)

Then it says:
was banned by Hi1!

I'm guessing it's trying to ban "null"?
Thanks in advance to any help!

Yes. That is what happens when you select null out of the list. You need to check to see if M is null before doing anything.

You also shouldn't call Logout() directly. I suggest just deleting them. Or, perhaps more elegantly, their client.

Well, I got it to not give me the error, but now no list box pops-up...

If there is only one item, it will automatically choose that item. This may be your problem.
You could try adding a "Cancel" option to your list. I think it would go something like...
Ban(mob/M as null|anything in players+"Cancel")
   if(M!="Cancel")
      ...
   else
      return

There's no reason to have a "Cancel" option if you're already getting a Cancel button from null|anything. The issue is that the players list is empty.

Ah, so is that what the null|anything did...

Well, this is how I'm adding players to the list:
// ADDING //
mob/Login()
    players += src.client.mob

// REMOVING //
mob/Logout()
    players -= src.client.mob


Then, I'm using this code for booting/banning:
ADMIN
    verb
        Boot(mob/M as null|anything in players)
            if(!M)
                return
            if(M.client)
                world << "<center><b>[M.key] was booted by [usr.key]!</b></center>"
                M.Logout()
            else
                del(M)
        Ban(mob/M as null|anything in players)
            if(!M)
                return
            world << "<center>[M] was banned by [usr.key]!</center>"
            banned += M
            M.Logout()


I don't see what's wrong...

You should just be adding src to the players list, not src.client.mob. However, I can't really think of a situation where there would be a difference, unless you're calling Logout() directly (which you are).

I changed it to del(M) but it still doesn't work...

I noticed that your not using ..() to call the default in mob/Login()

Do you have another mob/Login() in the code that may be blocking this one?

In response to Pirion
No, that's just part of my Login() code. I do use ..().

I tested this and it worked perfectly...do you have anything much different to this?

var/list
    players = new()
    banned = new()

mob/Login()
    ..()
    players += src
    verbs+=typesof(/ADMIN/verb)

// REMOVING //
mob/Logout()
    players -= src
    ..()

ADMIN
    verb
        Boot(mob/M as null|anything in players)
            if(!M)
                return
            if(M.client)
                world << "<center><b>[M.key] was booted by [usr.key]!</b></center>"
                M.Logout()
            else
                del(M)
        Ban(mob/M as null|anything in players)
            if(!M)
                return
            world << "<center>[M] was banned by [usr.key]!</center>"
            banned += M
            M.Logout()

Like Ganthor said, src.client.mob, and src don't make much of a difference here.

Hmm, I made my list like:
var/players = list()

Would that make it not work??
Feb 10 2010, 4:48 pm
In response to Hi1
No, that would not affect it.

The most likely explanation is that something is blocking that Login() from being called at all.
Feb 10 2010, 4:51 pm
In response to Garthor
Login() is being called, because I'm having the windows maximize and a window show in the Login(), they're both happening...
Feb 10 2010, 4:51 pm
In response to Hi1
Is it the same Login()?

Does the players list contain anything? Use a verb to check it.
Feb 10 2010, 4:55 pm
In response to Garthor
I checked it, it contains "Hi1"...but the boot/ban verbs still don't show any list at all...

What you've been told to do in this thread works perfectly fine.

Post what you have, again.

My Login/Logout:
mob/Login()
    ..()
    players += src
    winset(src, "Main", "is-maximized=true")
    if(src.key in banned)
        src << "<font color=red><b>You're banned...</b></font>"
        del(src)
    if(src.key in admins)
        src.verbs += typesof(/ADMIN/verb/)
        winset(src, "admin_menu", "is-disabled=false")
    src.loc=locate(5,3,1)
    src << output({"
    <center><b><u>Updates:</u></b></center><br><br>
    <u>Version 0.5</u><br>
    \tAdded this "Updates" Window, as well as "Guide", also fixed a bug dealing with Say.<br><br>
    "}, "Updates_Output")

mob/Logout()
    players -= src
    sleep(20)
    del(usr)
    if(playing)
        Save()
    else
        return
    ..()


My ADMIN verbs:
var
    admins=list("Hi1")
    banned=list()
    players=list()

ADMIN
    verb
        Announce(M as message)
            world << "<center><b>[usr.key] Announces:</b></center>\n[M]"
        Boot(mob/M as null|anything in world)
            if(!M)
                return
            if(M.client)
                world << "<center><b>[M.key] was booted by [usr.key]!</b></center>"
                M.Logout()
            else
                del(M)
        Ban(mob/M as null|anything in players)
            if(!M)
                return
            world << "<center>[M] was banned by [usr.key]!</center>"
            banned += M
            M.Logout()
        UnBan(mob/M in banned)
            switch(alert("Really UnBan [M.key]?","Really?","Yes","No"))
                if("Yes")
                    banned -= M.key
                    world << "<center>[usr.name] has unbanned [M.key]!</center>"
                else
                    return

Your boot verb is using "in world" instead of "in players".

You also are using usr in Logout(), which again is very very very very very wrong. Oh, and if you change it to del(src) which it should be, then it's still wrong because nothing after that will get executed.
