@peterson18 existe sim a possibilidade de alterar essas falas.
vá até a pasta data/npc/lib/npcsystem/ e abra o arquivo chamado npchandler.lua, você vai encontrar algo parecido com isso:
[MESSAGE_GREET] = 'Welcome, |PLAYERNAME|! I have been expecting you.',
[MESSAGE_FAREWELL] = 'Good bye, |PLAYERNAME|!',
[MESSAGE_BUY] = 'Do you want to buy |ITEMCOUNT| |ITEMNAME| for |TOTALCOST| gold coins?',
[MESSAGE_ONBUY] = 'It was a pleasure doing business with you.',
[MESSAGE_BOUGHT] = 'Bought |ITEMCOUNT|x |ITEMNAME| for |TOTALCOST| gold.',
[MESSAGE_SELL] = 'Do you want to sell |ITEMCOUNT| |ITEMNAME| for |TOTALCOST| gold coins?',
[MESSAGE_ONSELL] = 'Thank you for this |ITEMNAME|, |PLAYERNAME| gold.',
[MESSAGE_SOLD] = 'Sold |ITEMCOUNT|x |ITEMNAME| for |TOTALCOST| gold.',
[MESSAGE_MISSINGMONEY] = 'Sorry, you don\'t have enough money.',
[MESSAGE_NEEDMONEY] = 'You do not have enough money.',
[MESSAGE_MISSINGITEM] = 'You don\'t even have that item, |PLAYERNAME|!',
[MESSAGE_NEEDITEM] = 'You do not have this object.',
[MESSAGE_NEEDSPACE] = 'You do not have enough capacity.',
[MESSAGE_NEEDMORESPACE] = 'You do not have enough capacity for all items.',
[MESSAGE_IDLETIMEOUT] = 'Next, please!',
[MESSAGE_WALKAWAY] = 'How rude!',
[MESSAGE_DECLINE] = 'Not good enough, is it... ?',
[MESSAGE_SENDTRADE] = 'Here\'s my offer, |PLAYERNAME|. Don\'t you like it?',
[MESSAGE_NOSHOP] = 'Sorry, I\'m not offering anything.',
[MESSAGE_ONCLOSESHOP] = 'Thank you, come back when you want something more.',
[MESSAGE_ALREADYFOCUSED]= '|PLAYERNAME|! I am already talking to you...',
[MESSAGE_PLACEDINQUEUE] = '|PLAYERNAME|, please wait for your turn. There are |QUEUESIZE| customers before you.'
Você pode alterar conforme seu gosto nesse arquivo (*vai afetar todos os npcs).
Ou então alterar no próprio arquivo xml de cada NPC. exemplo:
<?xml version="1.0" encoding="UTF-8"?>
<npc name="Morgan" script="data/npc/scripts/vip/morgan.lua" walkinterval="2000">
<mana now="800" max="800"/>
<health now="200" max="200"/>
<look type="225" head="0" body="0" legs="0" feet="0" addons="0"/>
<parameters>
<parameter key="message_greet" value="Welcome, |PLAYERNAME|! I have been expecting you. Would like some {upgrades}? check {points}?" />
<parameter key="module_keywords" value="1" />
<parameter key="keywords" value="upgrades" />
<parameter key="keyword_reply1" value="I can sell for you.. {infinite potions} and upgrade spells for {sorcerer}, {druid}, {paladin} and {knight}. want to buy one?" />
</parameters>
</npc>
Dê uma certa atenção para a parte:
<parameter key="message_greet" value="Welcome, |PLAYERNAME|! I have been expecting you. Would like some {upgrades}? check {points}?" />
você pode alterar o message_greet para uma das opções:
MESSAGE_GREET
MESSAGE_FAREWELL
MESSAGE_BUY
MESSAGE_ONBUY
MESSAGE_BOUGHT
MESSAGE_SELL
MESSAGE_ONSELL
MESSAGE_SOLD
MESSAGE_MISSINGMONEY
MESSAGE_NEEDMONEY
MESSAGE_MISSINGITEM
MESSAGE_NEEDITEM
MESSAGE_NEEDSPACE
MESSAGE_NEEDMORESPACE
MESSAGE_IDLETIMEOUT
MESSAGE_WALKAWAY
MESSAGE_DECLINE
MESSAGE_SENDTRADE
MESSAGE_NOSHOP
MESSAGE_ONCLOSESHOP
MESSAGE_ALREADYFOCUSED
MESSAGE_PLACEDINQUEUE
Qualquer dúvida, volte a postar novamente ?
