Referencing LUA Tables in C++ Sources

[Icy]

Hello any potential thread readers, let me just tell you that I've been trying to figure this out for about two and a half hours now (currently 5:05 AM here :blink. Let me explain my dilemma:

The recent `doPlayerSetSpecialDescription` function was removed and as a result, one of my custom scripts that I was heavily working on got basically butt-fucked. I know that in player.cpp around lines 184-217 has this tidbit of code in it:

184	{
185		s << nameDescription;
186		if(!hasCustomFlag(PlayerCustomFlag_HideLevel))
187			s << " (Level " << level << ")";
188
189		s << ". " << (sex % 2 ? "He" : "She");
190		if(hasFlag(PlayerFlag_ShowGroupNameInsteadOfVocation))
191			s << " is " << group->getName();
192		else if(vocation_id != 0)
193			s << " is " << vocation->getDescription();
194		else
195			s << " has no profession";
196
...		s << getSpecialDescription();
...	}
...
...	std::string tmp;
...	if(marriage && IOLoginData::getInstance()->getNameByGuid(marriage, tmp))
...	{
...		s << ", ";
...		if(vocation_id == 0)
...		{
...			if(lookDistance == -1)
...				s << "and you are";
...			else
...				s << "and is";
...
...			s << " ";
...		}
...
...		s << (sex % 2 ? "husband" : "wife") << " of " << tmp;
...	}
...
...     s << ".";

And I'm wondering how I would insert a value based on what variables I have declared in an LUA creaturescript.

I know where I need to put it already

s << (sex % 2 ? "he" : "she") << " is insertLuaVariableHere (Level " << level << ")";

but unsure how I would go about implementing it, any help?

My LUA table looks somewhat like this:

local ADJECTIVE, MAX_ADJECTIVE = {
	[0] = {210, ""},
	[1] = {190, "awesome"},
	[2] = {45, "prosauce"}
}, 2

Bonus points if you can figure out how to display it in ADJECTIVE[1] colour (if that's even possible!).

Thanks in advance

If you are using 0.4_DEV then you can set string as storage, so you can do somethnig like:

doCreatureSetStorage(cid, 12345, ADJECTIVE[1][2])

Then in C++ part:

std::string strg;
getStorage(12345, strg);

s << (sex % 2 ? "he" : "she") << " is " << strg << "(Level " << level << ")";

doPlayerSetSpecialDescription was removed? o.0

int32_t LuaInterface::luaDoPlayerSetSpecialDescription(lua_State* L)
{
	//doPlayerSetSpecialDescription(cid, description)
	std::string description = popString(L);

	ScriptEnviroment* env = getEnv();
	if(Player* player = env->getPlayerByUID(popNumber(L)))
	{
		player->setSpecialDescription(description);
		lua_pushboolean(L, true);
	}
	else
	{
		errorEx(getError(LUA_ERROR_PLAYER_NOT_FOUND));
		lua_pushboolean(L, false);
	}

	return 1;
}

I still got it there...

but still using string storage seems to be better imo

Thanks Chojrak!

Ill have to test this out after the latest items.otb error is fixed.

Heres a little snipplet of code from a non-tibia related project I'm doing.

You'll be able to understand how it works if you simply analyze the code some.

//L->getGlobalFieldInteger(MAX_ADJECTIVE, 190, temp);
bool LuaScript::getGlobalFieldInteger(char* table, char* key, int &value)
{

	lua_getglobal(L, table);
	if (!lua_istable(L, -1))
	{
		lua_pop(L,1);
		return false;
	}

	lua_pushstring(L, key);
	lua_gettable(L, -2);
	if (!lua_isnumber(L, -1))
	{
		lua_pop(L, 1);
		return false;
	}

	value = (int)lua_tonumber(L, -1);
	lua_pop(L, 1);  // remove number and key
	return true;

}

}

Mmm, I guess that could work; not sure which way I'll try first now :/
