C++ Creature CastSpell() right way

[zxmatzx]

Hello,
I have this function to do Creatures cast spells, but isn't working in right way, if a monster(summon) cast a spell, the spell is damaging the player(master), if hit another player, the master don't get Skull, the master and the player that recive damage don't get Pz Locked. After search about i found this post where Delusion send a function to do Players cast spell, i noticed that he use another function to call the spell, and looking in this function all combat operations happens there, i want some help to do my function work in right way or adapt Delusion's function to work with Creatures(players, npcs and monsters), here is my function:

Luascript.cpp

registerMethod("Creature", "castSpell", LuaScriptInterface::luaCreatureCastSpell);

and

int LuaScriptInterface::luaCreatureCastSpell(lua_State* L)
{
    //creature:castSpell("name")
    const std::string& spellName = getString(L, 2);

    if(Creature* creature = getUserdata<Creature>(L, 1))
    {
        InstantSpell* spell = g_spells->getInstantSpellByName(spellName);
        if(!spell)
        {
            lua_pushboolean(L, false);
            return 1;
        }
        
        Creature* target = creature->getAttackedCreature();

        if (spell->getNeedTarget() == true)
        {
            if (target)
            {
                //TODO -> change to !canThrowSpell and only break returning false
                if (spell->canThrowSpell(creature, target) == true)
                {
                    spell->castSpell(creature, target);
                    lua_pushboolean(L, true);
                    return 1;
                }
                else
                {
                    lua_pushboolean(L, false);
                    return 1;
                }
            }
            else
            {
                lua_pushboolean(L, false);
                return 1;
            }
        }
        spell->castSpell(creature, creature);

        lua_pushboolean(L, true);
    }
    else
    {
        lua_pushboolean(L, false);
    }
    return 1;
}

LuaScript.h

static int luaCreatureCastSpell(lua_State* L);

Im using TFS 1.2, i guess change Delusion's function is better, because it already have all code to handler all things that i need.
Thanks!
