Say Links

[realityincarnate]

I played around with the idea a little bit tonight, and here's what I've come up with as a first attempt.

It only does the Titanium formating at the moment, and it will break if there are ever legitimate item ids over 1 million, but I tested a couple of different things and it seems to do all right. There's not much in the way of error checking, so it'll probably crash the zone if anything too strange gets entered as parameters.

The syntax is quest::saylink(message,n)
And when the link is clicked, it sends a message "SayLinkn". Here was my simple test script:

my $test1 = quest::saylink("trying,1");
my $test2 = quest::saylink("forget,2");

sub EVENT_SAY {
  if($text=~/Hail/i) {
    quest::say("I've noticed that sometimes certain words I say just feel... different.  Should I keep $test1 to see what I can do with them, or just $test2 the whole thing?");
  }

  if($text=~/SayLink1/) {
    quest::say("You're right, I bet I can make something out of them.");
  }
  if($text=~/SayLink2/) {
    quest::say("I knew it was too much to hope for.");
  }
}
