Lua Challenge on certain monsters?

[sestorme]

Is there any chance to set a challenge spell to work on certain monsters only? And is there a chance to put SPELL on Item function? : function onUse(cid, item, frompos, item2, topos)

Any help greatly appreciated +rep

dudeim's script might work if you change all the thing's to thing.uid like this:

local challengeMonsters = {
"Demon",
"Rat",
"Bear"
}

function onUse(cid, item, frompos, item2, topos)
local cpos = getCreaturePosition(cid)
local pos = {
[1] = {x=cpos.x-1,    y=cpos.y,    z=cpos.z,    stackpos=253},
[2] = {x=cpos.x-1,    y=cpos.y-1,    z=cpos.z,    stackpos=253},
[3] = {x=cpos.x,    y=cpos.y-1,    z=cpos.z,    stackpos=253},
[4] = {x=cpos.x+1,    y=cpos.y,    z=cpos.z,    stackpos=253},
[5] = {x=cpos.x+1,    y=cpos.y+1,    z=cpos.z,    stackpos=253},
[6] = {x=cpos.x,    y=cpos.y+1,    z=cpos.z,    stackpos=253},
[7] = {x=cpos.x-1,    y=cpos.y+1,    z=cpos.z,    stackpos=253},
[8] = {x=cpos.x+1,    y=cpos.y-1,    z=cpos.z,    stackpos=253}
}
local thing = 0
for i = 1,#pos do
    doSendMagicEffect(pos[i], CONST_ME_MAGIC_RED)
    local thing = getThingFromPos(pos[i])
    if isCreature(thing.uid) then
        if isInArray(challengeMonsters,getCreatureName(thing.uid)) then
            doChallengeCreature(cid, thing.uid)
        end
    end
end
return true
end

I also added a magic effect so you can see where the challenge checks
