[GOD Half]

Hi guys, I need fixing this problem. I did this script to summon some monsters, but he always summons the other players too, can anyone help me, please? Thank's

local configId = {
    [1] = {"Corym Charlatan"}
}

function onCastSpell(creature, variant)
for _, player in ipairs(Game.getPlayers()) do
local namePlayer = player:getName()
local positionPlayer = player:getPosition()
local summonPlayer = player:getSummons()
local target = player:getTarget()
local master = getCreatureMaster(namePlayer)
    if master then
        for _, i in pairs(configId) do
            if type(i) == 'table' then
                NamePet = i[1]
                if (#summonPlayer > 0) then
                    for _, SummonID in ipairs(summonPlayer) do
                        summonName = getCreatureName(SummonID)
                    end
                else
                    summonName = "no summon summoned"
                end
                if (summonName ~= NamePet) then
                    if target then
                        if isPlayer(target) or isMonster(target) then
                            local positionTarget = getCreaturePosition(target)
                            for r = 1, math.random(2,5) do
                                local PetNameSummon = doForceSummonCreature(NamePet, positionTarget)
                                doConvinceCreature(player, PetNameSummon)
                            end
                        end
                    else
                        for r = 1, math.random(2,5) do
                            local PetNameSummon = doForceSummonCreature(NamePet, positionPlayer)
                            doConvinceCreature(player, PetNameSummon)
                        end
                    end
                else
                    doPlayerSendCancel(player, "You already have summoned "..NamePet..".")
                return false
                end
            end
        end
    end
end
return true
