Hello, I need help with assigning IDs, for example I made a command for making apartments, but I want to assign IDs to them so that all this works every time the gamemode is ran, and later I can make a command to delete them, here's my code:

Код:

CMD:napravistan(playerid, params[], help)
{
	JeliLogovan
	if(PlayerInfo[playerid][pAdmin] < 6) return NematePravo
	if(AdminDuznost[playerid] == 0) return NisteAD
	else
	{
		new Float:x, Float:y, Float:z;
		GetPlayerPos(playerid, x, y, z);
		Create3DTextLabel("{FFDF2D}|     STAN     |\n{ffdf2d}|     CIJENA: $50.000     |\n{ffdf2d}|     {ffffff}Da kupite ovaj stan kucajte {ffdf2d}/kupistan     |", -1, x, y, z, 30.0, 0, 0);
		CreatePickup(19523, 2, x, y, z, 0);
	}
	return 1;
}

If more info needed, ask me in the comments.
EDIT: I figured out how I should do this, i need to make a txt file so every time I do the command it writes the ID in that file, and OnGameModeInit i just have to load that all, but how to make it all work?
