Lua Creaturescript/levitate problems

[swevaman]

Okay so the first problem is in this script I found on the forums, it works 100% fine EXCEPT when two people kill the monster... When that happens it will summon 2x (demon 2) instead of 1x like it should

local monster = "Demon"
local summon = "Demon 2"
function onKill(cid, target, lastHit)
    if isPlayer(target) then
        return true
    end
    if isPlayer(cid) and getCreatureName(target) == monster and not(getCreatureByName(summon)) then
        local t = getCreaturePosition(target)
        doCreatureSay(target, "I'm not finished with you yet!", 0x11)
        doSummonCreature(summon, t)
        doSendMagicEffect(t,1)
    end
    return true
end

Another issue is a little one, and I'm wondering if it's possible to block levitate on certain places? Like on a roof where you could normally levitate on, disable it?

@Levitate
You can place id 1548 there. It is invisible pathblocking tile.

local monster = "Demon"
local summon = "Demon 2"
function onKill(cid, target, lastHit)
    if isPlayer(target) then
        return true
    end
    if isPlayer(cid) and getCreatureName(target) == monster and not(getCreatureByName(summon)) and os.time() >= getStorage(75755) then
        local t = getCreaturePosition(target)
        doCreatureSay(target, "I'm not finished with you yet!", 0x11)
        doSummonCreature(summon, t)
        doSendMagicEffect(t,1)
        doSetStorage(75755, os.time() + 5)
    end
    return true
end

Thank you so much!

Is there a way to edit the 1548 tile through the .otb, to make it walkable?

Walkable BUT still unable to levitate on?
