Thank you.. it worked perfectly

I knew it was something simple that I had missed..

Ah..  That would make sense 

So moving the font as a public variable of IntroState would work? Have to try that tomorrow..  Thanks for the help

General / SFML2.1-VS12 - Program crashes when using font loaded from file.

« on: July 17, 2014, 12:21:17 am »

I'm trying to learn a little C++ and SFML and have started creating a little game. Sofar I've made a little stateengine and I'm currently trying to add stuff on my different states. I'm trying to add text to the window and tried first without using a font, but nothing was showing on the screen so I tried adding a font loaded from a file.

Code:

Game.cpp

void Game::run() {

        window.create(sf::VideoMode(800, 600), "SFML works!");

        stateEngine.run(StateEngine::build<IntroState>(stateEngine, window, true));

        while (stateEngine.isRunning()) {
                stateEngine.nextState();
                stateEngine.update();
                stateEngine.draw();
        }
}

#include "IntroState.hpp"

IntroState::IntroState(StateEngine& engine, sf::RenderWindow& window, bool replace)
        : GameState(engine, window, replace) {
        std::cout << "IntroState initialising.." << std::endl;

        //Set IntroState background
        if (!bgTex.loadFromFile("images/intro_bg.jpg"))
                std::cout << "Failed to load IntroState background image!" << std::endl;

        bg.setTexture(bgTex, true);

        sf::Font font;

        if (!font.loadFromFile("fonts/arial.ttf"))
                std::cout << "Failed to load arial!" << std::endl;

        //Set IntroState text
        introText.setFont(font);
        introText.setString("IntroText!");
        introText.setPosition(sf::Vector2f(10, 10));
        introText.setCharacterSize(30);
        introText.setStyle(sf::Text::Bold);
        introText.setColor(sf::Color::Red);
}

void IntroState::draw() {
        std::cout << "IntroState drawn" << std::endl;
        window.clear();
        window.draw(bg);
        window.draw(introText);
        window.display();
}

When the texture is drawn onto the window the program crashes with the following error message:

Code: [Select]

I have spent a few hours trying to fix this issue, but sofar I've gotten nowhere.. :/

I'm using Visual Studio 2013 and tried first with the VS11 version of SFML as there is no VS12 version yet. Then I tried compiling the VS12 version myself - no luck..

Now I'm thinking it might be a bug in sfml? or I'm missing something as I've tried everything I can think of (except the solution apparantly.. )

Any chance a more clever person can assist me on this one?

If you need more info just ask and I shall deliver!
