[sasuke.maria]

I maked this function for 1.3

function checkMonster()
    local spectator = Game.getSpectators(Position(55, 32, 5), false, false, 10, 10, 10, 10)
        if spectator:isMonster() and spectator:getName() == "Rat" then
            spectator:say("No! I am losing my energy!", TALKTYPE_MONSTER_SAY)
            spectator:remove()
            return true
        end
    return false
end

but i receveid this error:

Lua Script Error: [TalkAction Interface]
data/talkactions/scripts/woe.luanSay
data/talkactions/scripts/woe.lua:18: attempt to call method 'isMonster' (a nil value)
stack traceback:
[C]: in function 'isMonster'
data/talkactions/scripts/woe.lua:18: in function 'checkMonster'
data/talkactions/scripts/woe.lua:47: in function <data/talkactions/scripts/woe.lua:1>

Someone know why?
PS: i create this funcion on my custom lib.

function checkMonster(position, name)
    local specs = Game.getSpectators(position, false, false, 10, 10, 10, 10)
    for i = 1, #specs do
        local spec = specs[i]
        if isMonster(spec:getId()) and spec:getName() == name then
            spec:say('No! I am losing my energy!', TALKTYPE_MONSTER_SAY)
            spec:remove()
            return true
        end
    end
end

checkMonster(Position(55, 32, 5), 'Rat')

isMonster doesn't exist as a creature method
getSpectators returns a table of creatures userdatas so you have to iterate through the table checking for monster and the name
