クラスでpush_backを使用する際のトラブル

Question

クラス 'room'に 'push_back'ベクトル関数を使用する際に問題が発生しています。私は '部屋'クラスのプライベートベクトル変数に値をプッシュバックしようとしています。私は自分の問題は「push_back」機能の仕組みを誤解していると思っていますが、自分自身で問題を解決するために何が間違っているのか分かりません。

これは、問題領域である：

void room::assign_exit_index(int index) { 
    exit_index.push_back(index); 
} 

void room::assign_exit_direction(string direction) { 
    exit_direction.push_back(direction); 
} 

void room::assign_exit_locked(bool exit_locked) { 
    exit_locked.push_back(exit_locked); 
} 

void room::assign_gold(Money gold) { 
    gold.push_back(gold); 
} 

void room::assign_key(Key key) { 
    key.push_back(key); 
} 

void room::assign_potion(int potion) { 
    potion.push_back(potion); 
} 

void room::assign_have_weapon(bool have_weapon) { 
    have_weapon.push_back(have_weapon); 
} 

void room::assign_weapon_index(int weapon_index) { 
    weapon_index.push_back(weapon_index); 
} 

void room::assign_have_scroll(bool have_scroll) { 
    have_scroll.push_back(have_scroll); 
} 

void room::assign_scroll_index(int scroll_index) { 
    scroll_index.push_back(scroll_index); 
} 

void room::assign_have_monster(bool have_monster) { 
    have_monster.push_back(have_monster); 
} 

void room::assign_monster_index(int monster_index){ 
    monster_index.push_back(monster_index); 
} 

これは '部屋' クラスの宣言です：

class Money{ 

public: 

Money() { 
    value = 0; 
} 

Money(int amount) { 
    value = amount; 
} 

friend int operator +(Money& initial_amount, int money_added); 

private: 

int value; 

}; 

この：これは 'お金' クラス宣言である

class room{ 

public: 

    room(); 

    friend void generate_rooms (ifstream& input_file, vector<room>& rooms_f); 

    void assign_exit_index(int index); 
    void assign_exit_direction(string direction); 
    void assign_exit_locked(bool exit_locked); 
    void assign_gold(Money gold); 
    void assign_key(Key key); 
    void assign_potion(int potion); 
    void assign_have_weapon(bool have_weapon); 
    void assign_weapon_index(int weapon_index); 
    void assign_have_scroll(bool have_scroll); 
    void assign_scroll_index(int scroll_index); 
    void assign_have_monster(bool have_monster); 
    void assign_monster_index(int monster_index); 

private: 

    int room_index; 
    vector<int> exit_index; 
    vector<string> exit_direction; 
    vector<bool> exit_locked; 
    vector<Money> gold; 
    vector<int> key; 
    vector<int> potion; 
    vector<bool> have_weapon; 
    vector<int> weapon_index; 
    vector<bool> have_scroll; 
    vector<int> scroll_index; 
    vector<bool> have_monster; 
    vector<int> monster_index; 

};

あなたは、クラスメンバではなくパラメータでpush_backを呼び出して呼び出しています。 this->を使用してメンバを参照するか、パラメータとメンバの名前を異なるものにする（つまり、メンバ変数にアンダースコアを付ける）
