[ERROR] logout while talking with a NPC

[lordrai]

I'm getting a console error when someone dies or logout while talking with this npc

THE ERROR:

Lua Script Error: [Npc interface]

    end
end

function onThink()

    if focus == 0 then return true end
    if not isCreature(focus) then focus = 0 selfSay("Próximo por favor...") return true end

    doNpcSetCreatureFocus(focus)
    if not getDistanceToCreature(focus) or getDistanceToCreature(focus) > 30 then
                    selfSay('Próximo por favor...')
                    focus = 0
    end
  
end

Can someone help me, please?

I want the NPC to stop talk with someone only when someone walk more then 30 sqm or logout/die.

Did you try not using getcreatedistance(Cid) on the condition statement? I think is useless since you already assignment focus to the player, and the next one will only work if focus is set. Also I believe NPC handler would take care of the distance thing. Just try and see what happens

It didn't work =/

organizing better, the problem is here

function onThink()
    doNpcSetCreatureFocus(focus)

if not isCreature(focus) then
focus = 0
selfSay("message 1")
end


     if focus ~= 0 then
         if not getDistanceToCreature(focus) then
             selfSay('message 2')
             focus = 0
return true
         end
     end


     if focus ~= 0 then
         if getDistanceToCreature(focus) > 30 then
             selfSay('message 3')
             focus = 0
         end
     end

end

the condition on message 2 is the main condition to dont happen a error when someone logout/die
If I dont have this condition before the condition 3, I will get a error about nil.
this condition works, but when someone die/logout I still get a error on console, but the npc stills works...
the error is: LuaCreatureGetPos(). Creature Not Found

anyone know how to dont get this error?
