HELP in @item npc script

[Lord Ganja]

Hello, please help me with this. What script should I use in order for the npc to close whenever the input # is '0' or 'null'.

and whenever they input an ITEM ID which is NOT in the database it will say "Invalid Item ID"..

 

Thanks in advance..

 

Here's my script:

prontera,142,172,5    script    Item Giver    106,{
mes "[Item Giver]";
mes "Please input the ITEM NUMBER that you want to receive.";
mes " ";
mes "You could use @ii <item name> to look for it or browse at ratemyserver.net";
input [email protected];
next;
mes "[Item Giver]";
mes "How many pieces of this item do you want to receive?";
input [email protected];
next;
mes "[Item Giver]";
mes "Here you go! Come again!";
getitem [email protected],[email protected];
close;
end;
}

Therefor you can use the getiteminfo command.

if(getiteminfo([email protected], 0) == -1)
    // item does not exist

Because the variables you are using to store the input values  are integer the input will never be "null"; it's always a number.
To answer your question with an example:

input [email protected];
if ([email protected] == 0)
    close;

Thanks for the reply. But how about the item id which is not in the itemdb?

 

EDIT:

 

Nevermind, I already solved it. thanks anyway.
