Explicação: Criei este npc(Ty) para trocar 2 small diamonds(circulado em amarelo) por uma recording camera(circulado em laranja), está tudo funcionando, ele está fazendo a troca, logo, gostaria de acrescentar no npc(Ty) se o "jogador tem certeza que quer fazer essa troca", tipo o Sweety Cyclops do Tibia.

 

Como está: 

Ty: Hello | PLAYERNAME | I change 2 small diamonds for recording camera.

Tavarb: recording camera / camera

Ty: You just wap 2 small diamond for 1 recording camera.

 

 

Como preciso:

Ty: Hello | PLAYERNAME | I change 2 small diamonds for recording camera.

Tavarb: recording camera / camera

Ty: Do you want to trade 2 small diamonds for recording camera?

Tavarb: yes / no

(CASO YES) Ty: You just wap 2 small diamond for 1 recording camera.

(CASO NO) Ty: Ok, good bye.

(TIPO ESSE SRIPT) do Sweety Cyclops:

local node5 = keywordHandler:addKeyword({'ticket'}, StdModule.say, {npcHandler = npcHandler, onlyFocus = true, text = 'Do you want to trade a 50k for a ticket?'})
    node5:addChildKeyword({'yes'}, ticket, {npcHandler = npcHandler, onlyFocus = true, reset = true})
    node5:addChildKeyword({'no'}, StdModule.say, {npcHandler = npcHandler, onlyFocus = true, text = 'Alright then. Come back when you got the neccessary items.', reset = true})
