C++ Help with my c++ function creature:doCreatureCastSpell() TFS 1.2

[bizao030188]

Hi friends!
I am working in a function that makes monsters cast spells in lua environment.

The current version (below) is working but I cannot control the damage that it deals. I am trying to do as normal monsters does (use min and max values to calculate the damage) but I was not able.

int LuaScriptInterface::luaDoCreatureCastSpell(lua_State* L) 
{
    //doCreatureCastSpell(cid, spellname)
    Creature* creature = getCreature(L, 1);
    std::string spellName = getString(L, 2);
    if(creature){
        InstantSpell* spell = g_spells->getInstantSpellByName(spellName);
        if(!spell){
            lua_pushboolean(L, false);
            return 1;
        }
        Creature* target = creature->getAttackedCreature();
        if(target){
            spell->castSpell(creature, target);
        } else {
            spell->castSpell(creature, creature);
        }
        lua_pushboolean(L, true);
    } else {
        reportErrorFunc(getErrorDesc(LUA_ERROR_CREATURE_NOT_FOUND));
        lua_pushboolean(L, false);
    }
    return 1;
}

I appreciate any kind of help!
