Graphics / String error on a constructor of a class

« on: September 14, 2016, 04:48:41 pm »

I recently started to learn c++, so i'd like to have detailed explanations if you can.
(If i posted in the wrong section, i'm sorry)

Here's the code:

Player.h:

class Player {
public:
        Player(std::string, sf::Color);
        void Update();
        void Draw(sf::RenderWindow*, sf::RenderStates);

private:
        ...
        sf::Text nickname;
        sf::Font font;
}

Player.cpp

Player::Player(std::string _nickname, sf::Color color) {
...
        nickname.setFont(font);
        nickname.setString(_nickname);
        nickname.setCharacterSize(12);
        nickname.setFillColor(sf::Color(255, 255, 255));
}

void Player::Draw(sf::RenderWindow* window, sf::RenderStates states) {
        window->draw(_player, states);
        window->draw(nickname, states);
}

Here's the problem:

Main.cpp:

int main() {
        ...

        std::vector<Player> players;

        while (window.isOpen()) {

                std::string nickname; std::cin >> nickname;
                players.push_back(Player::Player(nickname, sf::Color(102, 0, 0)));

                window.clear();
       
                window.draw(cursor, states);
                for (auto player : players)
                        player.Draw(&window, states);
                window.display();
         }
}

When i try to write the nickname on the console, and press ente it gives me the following error:
"Debug assertion failed! Expression: map/set insert iterator out of range".

Thanks in advance.
