[31/12/2009 16:47:35] data/npc/lib/npc.lua:46: attempt to perform arithmetic on global 'sx' (a table value)
[31/12/2009 16:47:35] stack traceback:
[31/12/2009 16:47:35] data/npc/lib/npc.lua:46: in function 'getDistanceToCreature'
[31/12/2009 16:47:35] data/npc/scripts/oak info.lua:36: in function <data/npc/scripts/oak info.lua:33>

Anyone know what the problem could be?


here is the NPC

Lua: 
local focus = 0
local talk_start = 0
local target = 0
local following = false
local attacking = false

function onThingMove(creature, thing, oldpos, oldstackpos)

end

function onCreatureAppear(creature)
end

function onCreatureDisappear(cid, pos)
	if focus == cid then
		selfSay('Good bye then.')
		focus = 0
		talk_start = 0
	end
end


function onCreatureTurn(creature)
	
end


function msgcontains(txt, str)
return (string.find(txt, str) and not string.find(txt, '(%w+)' .. str) and not string.find(txt, str .. '(%w+)'))
end


function onCreatureSay(cid, type, msg)
msg = string.lower(msg)

if (msgcontains(msg, 'hi') and (focus == 0)) and getDistanceToCreature(cid) < 4 then
selfSay('Hi '..getPlayerName(cid)..'. Before you dare facing the Demon Oak, you should talk to my brother. Last time I heard from him he had settled down in a cave in the Sultans Castle. He had managed to dig a cave below his throne. Talk to him and then come back and ask me about the DEMON OAK.')
focus = cid
talk_start = os.clock()

elseif msgcontains(msg, 'hi') and (focus ~= cid) and getDistanceToCreature(cid) < 4 then
selfSay('Sorry, ' .. creatureGetName(cid) .. '! I talk to you in a minute.')

elseif focus == cid then
talk_start = os.clock()

if msgcontains(msg, 'demon oak') then
selfSay('So, you talked to my brother? Head south from here and use the mighty axe on the Oaks arms. If you defeat him, go talk to my brother again and ask him about the DEMON OAK.')
end

if msgcontains(msg, 'bye') and getDistanceToCreature(cid) < 4 then
selfSay('Good bye, ' .. creatureGetName(cid) .. '!')
focus = 0
talk_start = 0
end
end
end


function onThink()

if (os.clock() - talk_start) > 15 then
if focus > 0 then
selfSay('Next Please...')
end
focus = 0
end
if focus ~= 0 then
if getDistanceToCreature(focus) > 2 then
selfSay('Good bye then.')
focus = 0
end
end
end

the global TFS lua function "getDistanceToCreature" is at fault here.

Apparently in its function there's a bug which causes this error.
(Tries to do +-*/ or something on a variable which contains more than one value)

What TFS version do you use, and have you touched anything in your \data\lib\ folder?
