House command acces

[Bilip]

I need to make small change in (alevo grav) housebuy command ( required specified item to buy a house)
but, i can't find any file responsible for that.
This I found in talkactions/

<talkaction words="alevo grav" filter="word-spaced" event="function" value="houseBuy"/>

But there is no file housebuy at all! At least I can't find it.
How can I edit that ?
I know that probably I made most elementary mistake, but anyway don't laught at me

Ohh.. by the way:
I have another small unsolved problem:

I don't think there is a seperated file for that, i think its like "function" that has been introduced to server with compiling, if you want to change that you need to modify the sources and recompile, but i might be wrong, i am just telling what i think. Its better to stay without asnwer (has happened to me a lot lately on support boards)

talkaction.cpp
[CPP]bool TalkAction::houseBuy(Creature* creature, const std::string&, const std::string&)[/CPP]

Indeed it is in source, anyway I need help!
Do you guys know how to put another condition in this simple statement, I'm quite familiar with C++, but I have no idea, how to check if
player has some item or not
Aim: TO buy house player needs money AND item (ex. id=2400) (of cource it disappears after purchace) (It would be v easy in lua, so i'm sure it's also not hard in C++)

	if((uint32_t)g_game.getMoney(player) < house->getPrice() || !g_game.removeMoney(player, house->getPrice()))
	{
		player->sendCancel("You do not have enough money.");
		g_game.addMagicEffect(player->getPosition(), MAGIC_EFFECT_POFF);
		return false;
	}

This is the part of code we should edit!

Please help me As soon as possible!
