TFS 1.X+ Add Greet Massage to NPC

[kibo433]

Hi. I use TFS 1.5 downgrade by Nekiro to 8.0. I would like to add new greet and farewell keyword to npc like elves (ashari, asha thrazi). This is my npc.lua

local keywordHandler = KeywordHandler:new()
local npcHandler = NpcHandler:new(keywordHandler)
NpcSystem.parseParameters(npcHandler)

function onCreatureAppear(cid)              npcHandler:onCreatureAppear(cid)            end
function onCreatureDisappear(cid)           npcHandler:onCreatureDisappear(cid)         end
function onCreatureSay(cid, type, msg)      npcHandler:onCreatureSay(cid, type, msg)    end
function onThink()                          npcHandler:onThink()                        end



keywordHandler:addKeyword({'job'}, StdModule.say, {npcHandler = npcHandler, text = 'Have you moved to a new home? I\'m the specialist for equipping it.'})
keywordHandler:addKeyword({'offer'}, StdModule.say, {npcHandler = npcHandler, text = 'I sell statues, tables, chairs, flowers, pillows, pottery, instruments, decorations, tapestries, and containers.'})

local shopModule = ShopModule:new()
npcHandler:addModule(shopModule)

shopModule:addBuyableItem({"heart pillow"}, 1685, 30, "heart pillow")


local focusModule = FocusModule:new()
focusModule:addGreetMessage({'hi', 'hello', 'ashari'})
focusModule:addFarewellMessage({'bye', 'farewell', 'asha thrazi'})
npcHandler:addModule(focusModule)


npcHandler:setMessage(MESSAGE_GREET, "Ashari, |PLAYERNAME|.")
npcHandler:setMessage(MESSAGE_FAREWELL, "Asha Thrazi.")
npcHandler:setMessage(MESSAGE_WALKAWAY, "Asha Thrazi.")
npcHandler:setMessage(MESSAGE_DECLINE, "Hmm, but next time.")

npcHandler:setCallback(CALLBACK_MESSAGE_DEFAULT, creatureSayCallback)

npcHandler:addModule(FocusModule:new())

NPC is not loaded when starting the engine. This error appears:
Lua Script Error: [Npc interface]
data/npc/scripts/ukea.lua
data/npc/scripts/ukea.lua:22: attempt to call method 'addGreetMessage' (a nil value)
stack traceback:

[Warning - NpcScript::NpcScript] Can not load script: ukea.lua

When I used downgrade version to 8.6, it worked ok. I was trying to do it with this method:

keywordHandler:addGreetKeyword({'charach'}, {npcHandler = npcHandler, text = 'Ikem Charach maruk.'})
keywordHandler:addFarewellKeyword({'futchi'}, {npcHandler = npcHandler, text = 'Futchi!'})

but also to no avail.

Secondly, any of my NPCs react to DECLINE message changes. All other message changes like GREET, FAREWELL, WALKAWAY etc work fine, except this one.

OK. I solved it. I didn't notice that I have pasted to modules.lua this fragment of code in my TFS 1.5 downgrade to 8.6 . If we want to change greet message and farewell message our npc like a post above, we must paste it in our modules.lua

    -- Set custom greeting messages
    function FocusModule:addGreetMessage(message)
        if not self.greetWords then
            self.greetWords = {}
        end

        if type(message) == 'string' then
            table.insert(self.greetWords, message)
        else
            for i = 1, #message do
                table.insert(self.greetWords, message[i])
            end
        end
    end

    -- Set custom farewell messages
    function FocusModule:addFarewellMessage(message)
        if not self.farewellWords then
            self.farewellWords = {}
        end

        if type(message) == 'string' then
            table.insert(self.farewellWords, message)
        else
            for i = 1, #message do
                table.insert(self.farewellWords, message[i])
            end
        end
    end

    -- Set custom greeting callback
    function FocusModule:setGreetCallback(callback)
        self.greetCallback = callback
    end

    -- Set custom farewell callback
    function FocusModule:setFarewellCallback(callback)
        self.farewellCallback = callback
    end

As for the DECLINE message, we need to change in our modules.lua in
function ShopModule.onDecline from this:

        local msg = module.npcHandler:parseMessage(module.noText, parseInfo)
        module.npcHandler:say(msg, cid)
        module.npcHandler:resetNpc(cid)
        return true

to this:

        local msg = module.npcHandler:getMessage(MESSAGE_DECLINE)
        msg = module.npcHandler:parseMessage(msg, parseInfo)
        module.npcHandler:say(msg, cid)
        module.npcHandler:resetNpc(cid)
        return true
