[c++] passing lua tables arguments through c++ luainterface

[Doggynub]

okay i need to have this table in lua

local status = { equip = int , hold= int, depot = int, slot= int)

I want to make it like that with the lua api
i have a std:: map like that :
[cpp]
std::map<std::string,int> status;

status["equip"] = int;
status["depot"] = int;
status["hold"] = int;
status["slot"] = int;
[/cpp]

Now in the c++ this supposed to be a argument in a function in creatureevent, so how to make it the proper way i have it like that
[cpp]
lua_newtable(L);
LuaInterface::setField(L,"equip",(int32_t)status["equip"]);

LuaInterface::setField(L,"hold", (int32_t)status["hold"]);

LuaInterface::setField(L,"depot",(int32_t)status["depot"]);

LuaInterface::setField(L,"slot", (int32_t)status["slot"]);

[/cpp]

and i get that error in console when the event supposed to be executed

[Error - CreatureScript Interface]
data/creaturescripts/scripts/move.lua:onMoveItem
Description:

Create a creatureevent function and pass the parameters you want to have and then look at how it is send in lua..
Also you need to look at how it is checked if there is a creatureevent?
[cpp]uint32_t CreatureEvent::executeLook(Player* player, Thing* thing, const Position& position, int16_t stackpos, int32_t lookDistance)
{
//onLook(cid, thing, position, lookDistance)
if(m_interface->reserveEnv())
{
ScriptEnviroment* env = m_interface->getEnv();
if(m_scripted == EVENT_SCRIPT_BUFFER)
{
env->setRealPos(player->getPosition());
std::stringstream scriptstream;
scriptstream << "local cid = " << env->addThing(player) << std::endl;

scriptstream << "local thing = " << env->addThing(thing) << std::endl;
env->streamPosition(scriptstream, "position", position, stackpos);
scriptstream << "local lookDistance = " << lookDistance << std::endl;

scriptstream << m_scriptData;
bool result = true;
if(m_interface->loadBuffer(scriptstream.str()))
{
lua_State* L = m_interface->getState();
result = m_interface->getGlobalBool(L, "_result", true);
}

m_interface->releaseEnv();
return result;
}
else
{
#ifdef __DEBUG_LUASCRIPTS__
char desc[30];
sprintf(desc, "%s", player->getName().c_str());
env->setEventDesc(desc);
#endif

env->setScriptId(m_scriptId, m_interface);
env->setRealPos(player->getPosition());

lua_State* L = m_interface->getState();
m_interface->pushFunction(m_scriptId);

lua_pushnumber(L, env->addThing(player));
LuaScriptInterface:ushThing(L, thing, env->addThing(thing));

LuaScriptInterface:ushPosition(L, position, stackpos);
lua_pushnumber(L, lookDistance);

bool result = m_interface->callFunction(4);
m_interface->releaseEnv();
return result;
}
}
else
{
std::cout << "[Error - CreatureEvent::executeLook] Call stack overflow." << std::endl;
return 0;
}
}[/cpp]

already know that, as i can pass nomral arguments
[cpp]//custom moveuint32_t CreatureEvent::executeOnMove(Player* player, Item* item, const Position& fromPosition, const Position& toPosition,
Item* fromItem, Item* toItem, Item* fromGround, Item* toGround, std::map<std::string,int> status)
{
//onMoveItem(cid, item, formPosition, toPosition, fromItem, toItem, fromGround, toGround, equip, hold, depot, slot)
if(m_interface->reserveEnv())
{
ScriptEnviroment* env = m_interface->getEnv();
if(m_scripted == EVENT_SCRIPT_BUFFER)
{
env->setRealPos(player->getPosition());
std::stringstream scriptstream;
scriptstream << "local cid = " << env->addThing(player) << std::endl;


env->streamThing(scriptstream, "item" ,item, env->addThing(item));
env->streamPosition(scriptstream, "fromPosition", fromPosition);
env->streamPosition(scriptstream, "toPosition", toPosition);



env->streamThing(scriptstream, "fromItem",fromItem, env->addThing(fromItem));
env->streamThing(scriptstream, "toItem",toItem, env->addThing(toItem));
env->streamThing(scriptstream, "fromGround",fromGround, env->addThing(fromGround));
env->streamThing(scriptstream, "toGround",toGround, env->addThing(toGround));




scriptstream << "equip = " << (int32_t)status["equip"] << std::endl;
scriptstream << "hold = " << (int32_t)status["hold"] << std::endl;
scriptstream << "depot = " << (int32_t)status["depot"] << std::endl;
scriptstream << "slot = " << (int32_t)status["slot"] << std::endl;




if(m_scriptData)
scriptstream << *m_scriptData;


bool result = true;
if(m_interface->loadBuffer(scriptstream.str()))
{
lua_State* L = m_interface->getState();
result = m_interface->getGlobalBool(L, "_result", true);
}


m_interface->releaseEnv();
return result;
}
else
{
#ifdef __DEBUG_LUASCRIPTS__
char desc[30];
sprintf(desc, "%s", player->getName().c_str());
env->setEvent(desc);
#endif


env->setScriptId(m_scriptId, m_interface);
env->setRealPos(player->getPosition());


lua_State* L = m_interface->getState();
m_interface->pushFunction(m_scriptId);


lua_pushnumber(L, env->addThing(player));

LuaInterface:ushThing(L, item, env->addThing(item));
LuaInterface:ushPosition(L, fromPosition);
LuaInterface:ushPosition(L, toPosition);


LuaInterface:ushThing(L, fromItem, env->addThing(fromItem));
LuaInterface:ushThing(L, toItem, env->addThing(toItem));
LuaInterface:ushThing(L, fromGround, env->addThing(fromGround));
LuaInterface:ushThing(L, toGround, env->addThing(toGround));






lua_pushnumber(L, status["equip"]);
lua_pushnumber(L, status["hold"]);
lua_pushnumber(L, status["depot"]);
lua_pushnumber(L, status["slot"]);








bool result = m_interface->callFunction(12);
m_interface->releaseEnv();
return result;
}
}
else
{
std::clog << "[Error - CreatureEvent::executeMove] Call stack overflow." << std::endl;
return 0;
}
}
//
[/cpp]



but can't make a table having keys like i said up, it always gives error ,so i cant check it.
