    new name[TTT_ITEMLENGHT];
    formatex(name, charsmax(name), "%L", LANG_PLAYER, "TTT_ITEM_ID19");// TTT_ITEM_ID12 reemplazalo por otro aca y en el lang , ejemplo TTT_ITEM_ID16 = HE GRENADE
    g_iItemID = ttt_buymenu_add(name, get_pcvar_num(cvar_weapon_price), PC_TRAITOR); // en PC_TRAIDOR podes poner PC_DETECTIVE si es que queres que sea para detectives solamente
}
