Hello everyone, everything good?

I think it's the weirdest problem I've ever seen happen on a server, I have no idea what it causes. Sometimes on my server, when I talk to an NPC it responds as if it were another, example: my NPC Djin sometimes responds as if it were my NPC Task, it's very strange, the console doesn't give any error. Then I say "bye" and say "hi" again and he responds normally, has anyone been through this?

It only makes sense to me if it's something in the NPC lib, so I'll post npchandler.lua, follow:

Lua:
-- Advanced NPC System (Created by Jiddo),
-- Modified by TheForgottenServer Team,
-- Modified by The OTX Server Team.

if(NpcHandler == nil) then
    -- Constant talkdelay behaviors.
    TALKDELAY_NONE = 0 -- No talkdelay. Npc will reply immedeatly.
    TALKDELAY_ONTHINK = 1 -- Talkdelay handled through the onThink callback function. (Default)
    TALKDELAY_EVENT = 2 -- Not yet implemented

    -- Currently applied talkdelay behavior. TALKDELAY_ONTHINK is default.
    NPCHANDLER_TALKDELAY = TALKDELAY_ONTHINK

    -- Constant conversation behaviors.
    CONVERSATION_DEFAULT = 0 -- Conversation through default window, like it was before 8.2 update.
    CONVERSATION_PRIVATE = 1 -- Conversation through NPCs chat window, as of 8.2 update. (Default)
        --Small Note: Private conversations also means the NPC will use multi-focus system.

    -- Currently applied conversation behavior. CONVERSATION_PRIVATE is default.
    NPCHANDLER_CONVBEHAVIOR = CONVERSATION_DEFAULT

    -- Constant indexes for defining default messages.
    MESSAGE_GREET             = 1 -- When the player greets the npc.
    MESSAGE_FAREWELL         = 2 -- When the player unGreets the npc.

These are all self-contained functions, so is unlikely the issue.

My initial guess would be that something is loaded globally, such as a table, and your npc's are setup similar to one another, and are grabbing from the same place.

If that doesn't appear to be the case, then you'll need to start adding prints into the npc's and troubleshoot from there.

Happend again, strange, i realized what i have 2 npc who sells loot, and both of this two npcs have say NPC Task speech.

I managed to reproduce the problem: a person is talking to an NPC, if I arrive and say "hi", he will say he is busy. If the person is still trapped in that NPC and I talk to another free NPC, he will say that there is a person before me, as if he was occupied. When the first person leaves the NPC and I talk to anyone else, the NPC's next speech will be that of the first NPC I spoke to, when he was serving a person.

If I had to guess, I'd say it's this line,
Lua:
function greet(cid)                    talkState[cid] = 0     return true       end
Missing from line 10 of simple_task.lua

Its not just with Npc Task, happens with all npcs

Hello potinho.

My guess would be as Xikini said about globals, but everything looks fine. What domodlib('task_func') do on first line of sample_task.lua does?


Anyway, I took a look on both script, and something that caught my eye is on simple_task.lua on creatureSayCallback.

It initializes a local "talkUser" and it is used only on one place.
Lua:
local talkUser,msg, str,rst = NPCHANDLER_CONVbehavior == CONVERSATION_DEFAULT and 0 or cid, msg:lower(),"",""

This does not looks correct. It should use "cid" or "talkUser"

The problem doesn't just happen with these NPCs, with any NPC I talk to and then talk to another, the problem repeats itself. I tested it with this base and it also has the same problem. From what I've managed to research, I believe it's something in npchandler

 
Some guy just told me:

"You call npcHandler from addEvent function, Change self.focuses from integer to table"

But dont know what this means, dont know if helps to fix, still with problem.
 
We had the same problem in our server with some NPCs, we fixed it by removing this line of code on each affected NPC file. Hope it helps :)
Lua:
npcHandler:setCallback(CALLBACK_MESSAGE_DEFAULT, creatureSayCallback)
