NPC Trocador Simplificado - troca itens por itens

[Killua 389]

Eu vejo que existem varios NPCs que trocam itens por outros itens, mas os scripts sao sempre imensos... Eu resolvi fazer um que seja "unificado", tudo controlado por so uma tabela.

 

Esse eh o tipico NPC que vende itens, mas ao inves de dinheiro, ele cobra algum outro item.

 

Em data/npc/scripts crie trader.lua e coloque esse codigo:

---- NPC Trader por Killua, antigo amoeba13 ----

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

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
    
--- configure aqui
local str = ""
local coin = 2160 -- id do item que eh usado como moeda
    
local buyable_items = {      -- id dos itens e seus precos  
    {id = 2647, price = 4},
    {id = 2646, price = 5},
    {id = 2645, price = 6},
    {id = 2644, price = 7},
}

for u, offers in pairs(buyable_items) do
    
    function buyingit(cid, message, keywords, parameters, node)
        if(not npcHandler:isFocused(cid)) then
            return false
        end

        if getPlayerItemCount(cid,coin) >= offers.price then
            if doPlayerRemoveItem(cid,coin,offers.price) then
                npcHandler:say('Here you are. It was a pleasure doing buisiness with you.', cid)
                doPlayerAddItem(cid,offers.id,1)
            end
        else
            npcHandler:say('You do not have enough ' .. getItemNameById(coin) .. 's', cid)
        end
    end
        
    for i = 1, (#buyable_items - 1) do
        local name = getItemNameById(buyable_items[i].id)
        str = str .. name .. ', '
    end
    str = str .. getItemNameById(buyable_items[#buyable_items].id)
        
    local item_name = getItemNameById(offers.id)        
    
    keywordHandler:addKeyword({'trading'}, StdModule.say, {npcHandler = npcHandler, onlyFocus = true, text = "I trade {" .. str .. "} for some " .. getItemNameById(coin) .. "s."})
    local node1 = keywordHandler:addKeyword({''.. item_name .. ''}, StdModule.say, {npcHandler = npcHandler, onlyFocus = true, text = 'Do you want to trade a ' .. item_name .. ' for ' .. offers.price .. ' ' .. getItemNameById(coin) .. 's?'})
    node1:addChildKeyword({'yes'}, buyingit, {npcHandler = npcHandler, onlyFocus = true, reset = true})
    node1:addChildKeyword({'no'}, StdModule.say, {npcHandler = npcHandler, onlyFocus = true, text = 'Ok then, come back when you are ready for trading!', reset = true})
end
npcHandler:addModule(FocusModule:new())

Em data/npcs crie Trader.xml e coloque esse codigo:

<?xml version="1.0" encoding="UTF-8"?>
<npc name="Trader" script="trader.lua" walkinterval="2000" floorchange="0">
<health now="100" max="100"/>
<look type="300" head="0" body="0" legs="0" feet="0" corpse="5995"/>
<parameters>
<parameter key="message_greet" value="Hello |PLAYERNAME|! Do you want to do some {trading}?"/>
</parameters>
</npc>

Configurando:

 

Basta vc editar as variaveis com comentarios.

 

Vc pode adicionar mais tabelas livremente, sempre dessa forma:

{id = id do item, price = quanto custa o item},

Corrigindo um possível bug.

Se o NPC não funcionar em seu servidor ou der erro no console, vá até data/npc/lib /npcsystem e abra npchandler.lua. Apague tudo que tem nele e coloque isso:

Amoeba, quanto à essa parte que você mencionou, têm essa maneira:

local stt = ""
local items = {11641, 11640, 11639}    --ID dos items.
                
    for i = 1, #items do
        if stt == "" then
            stt = getItemNameById(items[i])
        else
            stt = stt..", "..getItemNameById(items[i])
        end
    end     
    
    print("Items: "..stt..".")

Se adicionar vários items, obviamente, a tabela ficará grande. Porém, o processo é menos cansativo, e mais fácil.

Sobre o NPC, achei ele bem legal, parabéns xd

Parabens a inteção foi muito boa desse seu npc usarei ele em uma novo projeto vlw amoeba.

[Vills 39]

Não funciona, não sei se é porque meu servidor é 10.1 sei lá, só sei que depois que você fala tradding e dis o nome do item que você quer não dá. ele simplesmente não fala nada.

[Killua 389]

Testei em tfs 0.3.6 e 0.4. Se o seu for um desses e nao funcionou vc deve ter colocado errado

[ScythePhantom 83]

Parabéns brother, muito bom.

[SrP1kachu 1]

esse npc é aquele que você fala " HI " " TRADE " ??
