verb
set category = "Speech" <------------1
say(mesg as text)
world << "[usr.key]: [mesg]"

1: cant do that mister.
has to come AFTER you define the verb
example
= tab
mob/verb
Say(T as text)
set category = "Speech"
world << "[usr.name]([usr.key]) says : [T]"

Obvously Nick hasnt contributed much to these forums and doesnt know that you have to explain what you are actually doing so newbies can understand.

Ok, well basically you have put set category in the wrong place. Here is what you should do. Oh and Nick, when you are posting code use ' 
' and '
' tabs.

    verb
        say(mesg as text)//Oh also I find it easier to use msg instead of mesg
            set category = "Speech"//As you see you need to put set category under the verb your defining
            world << "[usr.key]: [mesg]"

I hope this can help you.

Bah, dont use usr. Use src, much better. I am sure many people have discussed this before.

Yes, they work. But using usr in verb will lead to usr in procs which is a no-no.

Thanks for the help :)

I was wondering if you could explain why you can't use [usr.key] and why you should use [src.key]

Yes but you telling him NOT to use usr in a verb when its okay to.

I've had many problems in which I COULD NOT use src in a verb thus making the verb useless.

Try reading this. It'll tell you what you need to know.

no usr in verbs O.o
... Why you would like to know.
because verbs can be procs. and procs can be verbs.

At least I think... right XxDohxX?

The problem with using usr in procs is that usr is automatically set to the initiator of the verb that starts the thread of procs. What this means is demonstrated below: 
mob
    verb/say(t as text)
        view() << "[usr.key]: [t]"

    NPC
        verb/talk()
            set src in view()
            usr.say("Hello")
            src.say("Hi!")

This 'talk' verb will result in the following:
Hazman: Hello
Hazman: Hi
Why? Here's why:
mob
    verb/say(t as text)
        view() << "[usr.key]: [t]" //This is saying usr. Usr is automatically set when I use the 'talk' verb.

    NPC
        verb/talk()
            set src in view()
            usr.say("Hello") // The code is specifically saying 'Hazman (usr), say "Hello"'
            src.say("Hi!") //While this is saying 'Tell the usr, Hazman, to say, "Hi!"'

Of course, when I say 'saying' I mean calling, but to make it more understandable I used

Mind you all this is being done within a verb. usr is perfectly all right in verbs. The only case where you should avoid it is if you're going to be calling that verb as if it's a proc. For example, if to make NPCs talk you route everything through say(), then you'd want to use src instead of usr.

As it is I'd leave it with usr.key.

Uh, no. You have no idea what you're saying.

usr in verbs is not only okay; it's expected. You can use usr all you want in verbs. That has nothing to do with whether you misused it in a proc.

The only time usr is unsafe in a verb is if you're treating that verb as a proc and manually calling it from other places in your code.

As it is it's not wrong to use src.key, but it's just as valid as usr.key here unless that verb is going to be pulling double-duty as a proc.

I think what he was getting at is that getting used to using usr (heh) in verbs might spread to accidentally using usr in procs as well... So, it's just better to be safe and never use usr at all, even when it's alright...

If you're paying attention, this isn't a problem, but these days, who's paying attention? lol

So I was right, right Lummox JR?

You're putting the category before the defined verb.

    verb
        say(mesg as text)
            set category = "Speech" // That's where it needs to go.
            world << "[usr.key]: [mesg]"

No, only if verbs are going to be used as procs, which is quite rare. And in those cases the author knows what they're doing.

Putting usr in a verb is natural and shouldn't be given a second thought, unless you're doing the above in which case all bets are off, and you'd know it.
