Lua NPC and tiles[Solved]

[Shinmaru]

Is there a way to get and NPC to say something when you step on a certain tile?

 

[Summ]

onStepIn -> Either npc = getCreatureByName("NPCNAME") (if you use the npc only once) or check the tiles where the npc could be at the moment and npc = getThingFromPos(tile).uid
doCreatureSay(npc, "Something)

 

[Cykotitan]

getThingFromPos(tile)

There's a getTopCreature function for a reason

 

[Shinmaru]

OK here is my script:

local cfg = {
	[7] = {x = 1295, y = 1689, z = 7, stackpos = 253},
	[5] = {x = 1296, y = 1691, z = 5, stackpos = 253}
	}
local function getNPCs(cid)
	local pos = cfg[getCreaturePosition(cid).z]
	local NpCid = getThingFromPos(pos.x, pos.y, pos.z, pos.stackpos)
	if isNpc(NpCid) == true then
		return NpCid
	else
		return print('[Error:Not a Npc.]'..NpCid)
	end
end	

local function doNPCSay(NpCid, msg, rndm)
	if rndm == true then
		return doCreatureSay(NpCid, math.random(#msg), TALKTYPE_SAY)
	end
	return doCreatureSay(NpCid, msg, TALKTYPE_SAY)
end	
function onStepIn(cid, item, position, lastPosition, fromPosition, toPosition)
local npc = getNPCs(cid)
	if getCreatureStorage(cid, 1500) == 0 then
		doCreatureSetStorage(cid, 1500, 1)
		doNPCSay(npc, {'Go on through I can see you are strong enough!', 'Head on '..getCreatureName(cid)..' the king awaits!'}, true)
	elseif getCreatureStorage(cid, 1500) == 1 then
		doTeleportThing(cid, fromPosition, true)
		doNPCSay(npc, 'You have nothing else to do here!')
	else
		doTeleportThing(cid, fromPosition, true)
		doNPCSay(npc, 'You\'re still too weak to venture forward in this path.')
	end
return true
end

and here is my error:

[18:33:13.259] [Error - MoveEvents Interface]

Now what could be the problem?

you have to make it like that:

getThingFromPos([b][color="red"]{[/color][/b][b][color="red"]x=pos.x[/color][/b], [b][color="red"]y=pos.y[/color][/b], [b][color="red"]y=pos.z[/color][/b], [b][color="red"]stackpos=pos.stackpos[/color][/b][b][color="red"]}[/color][/b])

also use getTopCreature() like Cykotitan said

 

[Darkhaos]

Use "getNpcCid()" or "getNpcPos()"

npcCid = getNpcCid()
doCreatureSay(npcCid, TALKTYPE_MONSTER, "I'm a npc")

 

[Qbee]

doCreatureSay(getCreatureByName("NPCNAME"), "WTF")

 

[Cykotitan]

Use "getNpcCid()" or "getNpcPos()"

npcCid = getNpcCid()
doCreatureSay(npcCid, TALKTYPE_MONSTER, "I'm a npc")

That can be only used in NPC scripts, and it would be inefficient to use that in the NPC's onThink.
