Lua NPC Editing: How to code items worth less than 1 gold.

[Drakkhan]

Is it possible to set an NPC to sell things for less than 1 gold? I'm trying to set it to sell feathers, but 1 gold coin seems excessive for 1 feather.

Any ideas!? Anything would be helpful.

Thanks!

you should make a new coin which value is something like 0.001 GP. But you also can make that npc to sell 2xfeather for a GP, buy talking not by the trade windows

I'm running TFS_10_915.

This is my code:

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

As you can see, I've used addBuyableItemContainer() to sell multiple feathers per coin.. I wish there was a more direct way, but I'm afraid to set a price less than 1 gold coin, because I figure people will be able to buy 1 feather for 0 gold coins, then.

Thanks for taking the time to look into this, by the way. I'm trying to avoid a source code edit if possible. My C++ is rusty.

I have made a crafting system. Good eye! This NPC sells a large amount of the raw materials required to participate in crafting.
