I tryied to do a script for make a random summon.
But i got this error:

[error] Lua script error:
error... boss_summon.lua:14: attempt to compare nil with number stack traceback:
[C]: in function '__lt'
...boss_summon.lua:14: in function boss_summon.lua:10

Lua: 
local combat = Combat()
combat:setParameter(COMBAT_PARAM_TYPE, COMBAT_NONE)
combat:setParameter(COMBAT_PARAM_EFFECT, CONST_ME_NONE)

local area = createCombatArea(AREA_CIRCLE2X2)
combat:setArea(area)

local spell = Spell("instant")
function spell.onCastSpell(creature, var)
    local creatures = { "Rat", "Sibang", "Tarantula" }
    local monster = creatures[math.random(#creatures)]

    if minorsummon < 5 then
        Game.createMonster(monster, { x = creature:getPosition().x + math.random(-1, 1), y = creature:getPosition().y + math.random(-1, 1), z = creature:getPosition().z }, false, true)
        minorsummon = minorsummon + 1
    end
    return combat:execute(creature, var)
end

spell:name("minorsummon")
spell:words("###1246")
spell:blockWalls(true)
spell:needLearn(true)
spell:register()

Someone know how to declare this variable?

This should work fine:

Lua: 
local combat = Combat()
combat:setParameter(COMBAT_PARAM_TYPE, COMBAT_NONE)
combat:setParameter(COMBAT_PARAM_EFFECT, CONST_ME_NONE)

local area = createCombatArea(AREA_CIRCLE2X2)
combat:setArea(area)

local creatures = {"Rat", "Sibang", "Tarantula"}
local maxSummons = 5

local spell = Spell("instant")

function spell.onCastSpell(creature, var)
    local monster = creatures[math.random(#creatures)]
    local mySummons = creature:getSummons()
    if #mySummons >= maxSummons then return false end
    local summon = Game.createMonster(monster, {
        x = creature:getPosition().x + math.random(-1, 1),
        y = creature:getPosition().y + math.random(-1, 1),
        z = creature:getPosition().z
    }, false...

        minorsummon = minorsummon + 1
    end

It will work but problem is if one monster die the script still think its 5 summons and in that case it won't work anymore
Maybe he want it like that, no clue
