characters does not have a len variable. A bit more code, like where you define characters, would be helpful.

I think what 'XzDog' and 'Jon' meant was 'show where you define your characters variable', and the code around that.

Sorry for not being specific enough, but i was talking about the people who were trying to help him

He obviously didn't. He simply heard somoene say to use "characters.len", and assumed that plugging that into his code would work.

mob/creating_character
    src.CreateCharacter() //This tells the src to lookup "CreateCharacter"

    proc/CreateCharacter()
        var/mob/new_mob //We are declaring a new variable called "new_mob" which will be used in a little minute
        var/char_name // We set a var for the characters name here and make it "null"
        while(!char_name) // Here we check to see whether the characters name is null or text, if null we don't allow them in, if text, they are allowed in
            char_name = input("What is your name?","Create a character") as null|text //The player makes their name here
            char_name = html_encode(char_name)

        if (!char_name)
            // Guess they don't want to create a new character after all, so send them to choose a character.
            client.base_ChooseCharacter()
            return

        var/ckey_name = ckey(char_name)
        var/list/characters = client.base_CharacterNames()

I'm just going to assume that you meant to indent that under mob/creating_character/New(), since you can't call a proc like that.

Yes i know but that doesnt help me with my current problem.

var/list/characters = client.base_CharacterNames()

Your problem would have to be in base_CharacterNames(). Whatever it's returning isn't a list. Did you copy and paste part of the base_CharacterNames() proc from the library and somehow mangle or alter it?

Don't put usr in a proc.

If you're not going to view posts in threaded mode, be absolutely sure you're replying to the right post. In this case you didn't.

You need to define the characters var as a list.

You probably have:
var/characters

You should have:
var/list/characters

Since the len var only exists on /list objects.

See http://developer.byond.com/forum/ index.cgi?action=message_read&id=259220&forum=8&view=0

It appears to be var/list/characters
