Lua NPC System (Choice in Default / NPCs Channels?)

[dbrown30]

Hello there,

I'm a little new, so please forgive me if this is a newbie question, but I've had a hard time finding my answer.

I'm using TheForgottenServer 8.60 V2.5

Is it possible to choose for NPCs to talk only in the Default channel or only in the NPCs channel? Mine currently speak in both.

Also, I was thinking about using only the Default channel and have it like the earlier system without using the NPCs channel at all, if possible. Is it possible to remove the NPCs channel entirely from the game? It's not on the list of channels in the channels.xml file.

Thanks for all help!

Post the npc.lua script that speaks in both channels

Hi Sizaro,

Thank you for the quick reply!

Here is the npc.lua file:

-- Include the Advanced NPC System
dofile(getDataDir() .. 'npc/lib/npcsystem/npcsystem.lua')

function selfIdle()
	following = false
	attacking = false

	selfAttackCreature(0)
	target = 0
end

function selfSayChannel(cid, message)
	return selfSay(message, cid, false)
end

function selfMoveToCreature(id)
	if(not id or id == 0) then
		return
	end

	local t = getCreaturePosition(id)
	if(not t.x or t.x == nil) then
		return
	end

	selfMoveTo(t.x, t.y, t.z)
	return
end

function getNpcDistanceToCreature(id)
	if(not id or id == 0) then
		selfIdle()
		return nil
	end

	local c = getCreaturePosition(id)
	if(not c.x or c.x == 0) then
		return nil
	end

	local s = getCreaturePosition(getNpcId())
	if(not s.x or s.x == 0 or s.z ~= c.z) then
		return nil
	end

	return math.max(math.abs(s.x - c.x), math.abs(s.y - c.y))
end

function doMessageCheck(message, keyword)
	if(type(keyword) == "table") then
		return table.isStrIn(keyword, message)
	end

	local a, b = message:lower():find(keyword:lower())
	if(a ~= nil and b ~= nil) then
		return true
	end

	return false
end

function doNpcSellItem(cid, itemid, amount, subType, ignoreCap, inBackpacks, backpack)
	local amount = amount or 1
	local subType = subType or 1
	local ignoreCap = ignoreCap and true or false

	local item = 0
	if(isItemStackable(itemid)) then
		item = doCreateItemEx(itemid, amount)
		if(doPlayerAddItemEx(cid, item, ignoreCap) ~= RETURNVALUE_NOERROR) then
			return 0, 0
		end

		return amount, 0
	end

	local a = 0
	if(inBackpacks) then
		local container = doCreateItemEx(backpack, 1)
		local b = 1
		for i = 1, amount do
			item = doAddContainerItem(container, itemid, subType)
			if(itemid == ITEM_PARCEL) then
				doAddContainerItem(item, ITEM_LABEL)
			end

			if(isInArray({(getContainerCapById(backpack) * b), amount}, i)) then
				if(doPlayerAddItemEx(cid, container, ignoreCap) ~= RETURNVALUE_NOERROR) then
					b = b - 1
					break
				end

				a = i
				if(amount > i) then
					container = doCreateItemEx(backpack, 1)
					b = b + 1
				end
			end
		end

		return a, b
	end

	for i = 1, amount do
		item = doCreateItemEx(itemid, subType)
		if(itemid == ITEM_PARCEL) then
			doAddContainerItem(item, ITEM_LABEL)
		end

		if(doPlayerAddItemEx(cid, item, ignoreCap) ~= RETURNVALUE_NOERROR) then
			break
		end

		a = i
	end

	return a, 0
end

function doRemoveItemIdFromPos (id, n, position)
	local thing = getThingFromPos({x = position.x, y = position.y, z = position.z, stackpos = 1})
	if(thing.itemid == id) then
		doRemoveItem(thing.uid, n)
		return true
	end

	return false
end

function getNpcName()
	return getCreatureName(getNpcId())
end

function getNpcPos()
	return getCreaturePosition(getNpcId())
end

function selfGetPosition()
	local t = getNpcPos()
	return t.x, t.y, t.z
end

msgcontains = doMessageCheck
moveToPosition = selfMoveTo
moveToCreature = selfMoveToCreature
selfMoveToPosition = selfMoveTo
selfGotoIdle = selfIdle
isPlayerPremiumCallback = isPremium
doPosRemoveItem = doRemoveItemIdFromPos
doNpcBuyItem = doPlayerRemoveItem
doNpcSetCreatureFocus = selfFocus
getNpcCid = getNpcId
getDistanceTo = getNpcDistanceTo
getDistanceToCreature = getNpcDistanceToCreature

And just additional information, here is the XML of the NPC script:

<?xml version="1.0" encoding="UTF-8"?>
<npc name="John" nameDescription="John" script="default.lua" speed="110" walkinterval="2000" floorchange="0" skull="none" hidename="0" hidehealth="0">
	<health now="100" max="100"/>
	<look type="128" head="114" body="115" legs="126" feet="76" addons="0"/>
	<parameters>
		<parameter key="module_keywords" value="0" />
		<parameter key="message_farewell" value="Feel free to come back and see me again if you need anything!" />
		<parameter key="message_greet" value="Hello |PLAYERNAME|! Would you like to know some tips? Just say {yes} if so."/>
		<parameter key="message_idletimeout" value="Hello? Ok... please say {hi} to me again if you need {help}." />
		<parameter key="message_walkaway" value="See you later." />
	</parameters>
</npc>

EDIT: Actually, I think this is what you needed. default.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

npcHandler:addModule(FocusModule:new())

Please let me know if I can provide any additional information.
