[TFS 1.0] NPC will say one of x random lines when you greet them.

[Jaed Le Raep]

So, for this request I was hoping someone could make what I think is a pretty simple template. When a player says hi to a NPC, they'll say one of a set of 10 lines. This will only happen when they greet the npc, and the npc will have no other dialogue with the player until they say bye and re-greet them.

Also, while I'm requesting this, can someone please refresh my memory and tell me how have NPCs say a random line as they walk around? This would be without them being spoken to, every x seconds they have x chance of saying x line(s).

Lol, well that was quick. Much appreciated, will test them right now and let you know how they work out

Edit:
Got this error, over and over again.

I had existing script so I just pasted it there.
Use different random_word variable for every npc
if you use same, they won't speak or speak very rarely

Thanks for the help Any thoughts on the error I received?

Edit: Just noticed the last parsed code. Hmm.. where would it go?

It's been about two years since I've worked on OTs and I'm super rusty, so a lot of this is about memory reflex for me (which isn't proving to be very reliable x.x)

I'll post whole npc. You should be able to spot reference points

It isn't working:

function onThink(interval)
  if(random_word_arena < os.time()) then
    random_word_arena = (os.time() + random_texts_interval)
    if(math.random(1, 100) < random_texts_chance) then
      selfSay(random_texts[math.random(1, #random_texts)])
    end
  end
  npcHandler:onThink()
end

function onPlayerEndTrade(cid)        npcHandler:onPlayerEndTrade(cid)      end
function onPlayerCloseChannel(cid)      npcHandler:onPlayerCloseChannel(cid)    end
function greetCallback(cid)
  local talkUser = cid
  local msg = {
    "Welcome to the {Arena}, " .. getPlayerName(cid) .. ".",
    "No need to extend that discussion. If you want to {fight} just ask.",
    "Welcome, " .. getPlayerName(cid) .. ". Welcome to the {Arena}.",
    "Be greeted.",
    "Hello, " .. getPlayerName(cid) .. "."
  }
  npcHandler:setMessage(MESSAGE_GREET, msg[math.random(1, #msg)])
  npcHandler:setCallback(CALLBACK_GREET, greetCallback)
  talkState[talkUser] = 0
  return true
end
