        Gate
            icon_state="gate"
            density = 1
            Click()
                if(src in oview(2))
                    var/password_1 = input("Please input a password") as password
                    if(!password_1) return

                    if(findtext("PISH")) in passwords //line with the problem
                        usr.loc = locate(/area/teleports/ZZ)

                    if(password_1=="PISH")
                        usr.loc = locate(/area/teleports/ZZ2)
                        usr.passwords+= "PISH"


What i want this to do is find the text PISH in the lists passwords. I always get stuck on lists,Where did i go wrong here?

findtext isn't for lists, you should be using Find().

how would i impliment this? 
if(list.Find(Elem,Start=1,End=0))


Like that?

Nope,
if(passwords.Find("PISH"))


I think also using if(("PISH" in passwords)) would work, but I'm not too sure.

Well, here is an example how to use Find()

var/list/beta = list("Jiskuha","N1ghtW1ng")

mob/Login()
   if(beta.Find(src.key))
      ..()
   else
      src << "Sorry you aren't a beta tester"

That should work -_-

            icon_state="gate"
            density = 1
            Click()
                if(src in oview(2))
                    var/password_1 = input("Please input a password") as password
                    if(!password_1) return
                    if(passwords.Find("PISH"))
                        usr.loc = locate(/area/teleports/PISH)
                    if(!usr.passwords)
                        if(password_1=="PISH")
                            usr.loc = locate(/area/teleports/PISH)
                            usr.passwords+= "PISH"

It's not really a list.
Try
mob/var/list/passwords=list()
:)

I still keep getting the error on the same line..

                    if(passwords.Find("PISH"))

In the Click() proc, instead replace the following:
if(passwords.Find("PISH))

with

if(usr.passwords.Find("PISH"))

Whoops! My mistake. Thanks for fixing it, Radd.

One last thing, how would i check if the list was empty or not?

if(!list.len)
Easy, eh?
Jan 19 2005, 4:18 pm
In response to Hell Ramen
And the alternate way:

if (!length(thelist))


Both work. Which one you use is just a matter of style.

Click()
    ..()
    if(src in oview(2))


For click statements. ..() always needs to be called at leaste once.

I'd just like to note that it was a list, it's just that Dream Maker didn't know it was. =)

It probably wouldn't hurt, but it doesn't always have to be called. It just depends on how you want it to work, if you specifically don't want any parent proc called, then you can leave it out. And what do you mean by at least once? There's no reason to call the parent proc more than once. =)

I was always told to like, call the parent for Click() and topic links and stuff XD

It would, but in that case, you don't need the extra set of parenthesis (not that it will do any harm, of course):

if("PISH" in passwords)


Of course, if you want to find out if PISH isn't in passwords, then you need the parenthesis because of order of operations:

if(!("PISH" in passwords))
