                usr.verbs += typesof(/mob/Guild/verb)
                del(src)

here is the error on the Dreamseeker

runtime error: Cannot execute null.Find().
proc name: MakeGuild (/obj/guild/make/verb/MakeGuild)
  source file: Guild.dm,12
  usr: Ky (/mob/characters/Mutant)
  src: the make (/obj/guild/make)
  call stack:
the make (/obj/guild/make): MakeGuild()


I think the error is trying to find the guild if its excist on the sav file but when it doesn't it returns with this error!

i need help but i want to know whats wrong instead of giving me the code. i want to learn the error thats the main reason for posting this thread!

I think try
if(!global.guilds.Find("[gname]"))

before you create the save file

I think the problem might be this line. I don't think that's how to load something from a savefile. Try doing F["Guilds.sav"] >> global.guilds

You're using Find() incorrectly.

if(global.guilds.Find(gname))

i am quite sure thats right but i might be mistaken the global var list. could you please explain to me in details

Find() is used to return a position in a list, you should be using the in operator. :p

So? If the item is found, the position will be greater than 0, so his way works too.

I have done that but its not the problem making the errors. which occur on dreamseeker. DM is not finding any errors on it because its not influencing the coding to load. i just making a mistake in global sav and finding the text for it

But if the list is empty, then Find() can't go through it, thus generating an error.

I know its trying to find a obj from a list and i need to know whats wrong with it. I think the code below influencing it.

var/savefile/F = new("Guilds.sav")
            F["Guilds.sav"] >> global.guilds
            var/gname = input ("What do you wish to name this guild?") as text|null
            if(global.guilds.Find(gname))


please explain your help in details.

Yeah, but most DBZers know him from LoTD, and he still uses Goku72 for that.

I am pretty sure Jon was right. Try and put >> instead of =. If any errors come up, tell us what they are.

there is no error and the error shows up on the Dream seeker!

runtime error: Cannot execute null.Find().

That is called a runtime error. Did you do what Jon and I said?
