qglobals

[Richardo]

I am trying to understand Global Variables. Would this work? If not, why?

sub EVENT_SAY
my $conversation = $qglobals{remember_conv};
{
if($text=~/hail/i && $conversation = "0")
{
quest::setglobal("remember_conv", $conversation, 5, "F");
quest::say("I will remember you, next time you hail me!");
}
if($text=~/hail/i && $conversation = "1");
{
quest::say("We have talked before!");
}
}

Make sure you checked the setting for quest globals for the npc in npc_types

Ah, the npc needs qglobals enabled on them? I see. So as far as that, I got the syntax correct?

Close. Make sure you have "==" or "eq" (in the case of string comparison) in your if statements. Which you would probably figure out as soon as you ran it.

No need to assign a variable to the global, since the global is a variable. This would work better for you, and won't throw up warnings in the logs:

sub EVENT_SAY {
  if($text=~/hail/i && !defined $qglobals{conversation}){
quest::setglobal("conversation", 1, 0, "F");
quest::say("I will remember you, next time you hail me!");
 }
  elsif($text=~/hail/i && defined $qglobals{conversation}){
quest::say("We have talked before!");
 }
}

Yeah I understand general things like that. == for intergers eq for strings. Thanks for your help guys!

We never had to do this at first (would work anyways), but now we do, so it's always the first thing I forget when I do quests.

Do you guys know if it's possible to make a quest to where once an npc is hailed, no one else can talk to him until the global variable expires?

Yep,

quest::setglobal("name",1,2,"M10");

will be available to the NPC who called it, from the zone they called it in, and to all players for 10 minutes. The second number is the option and what calls this behavior. Here are the proper values, taken from the wiki:

-----------------------------------------
|  value |  npcid  |  player |   zone   |
-----------------------------------------
|   0    |  this   |   this  |   this   |
|   1    |  all    |   this  |   this   |
|   2    |  this   |   all   |   this   |
|   3    |  all    |   all   |   this   |
|   4    |  this   |   this  |   all    |
|   5    |  all    |   this  |   all    | 
|   6    |  this   |   all   |   all    |
|   7    |  all    |   all   |   all    |
