sfml – How can I make the textual content flash?

there have been a bunch of bugs in your code. It is a working instance, there are a lot of approach of getting this applied. In precept you employ the identical technique as for animating a sprite.

For animations you want to seize the time. Otherwise you won’t be able to calculate the length per body. And you want to retailer the present body in a variable. I put some remark within the instance code beneath.

Btw, in case you are not used to sport loops, take a look on https://gafferongames.com/publish/fix_your_timestep/

int fundamental(){
    int LAYOUT_WINDOW_WIDTH = 800;
    int LAYOUT_WINDOW_HEIGHT = 600;

    sf::RenderWindow window(sf::VideoMode(LAYOUT_WINDOW_WIDTH, LAYOUT_WINDOW_HEIGHT),
        "Tetris 2019 - A New Starting");

    sf::Font myFont;
    if (!myFont.loadFromFile("cartoon reduction.ttf")) {

    }

    window.setFramerateLimit(30);

    sf::Textual content gameOver;
    gameOver.setFont(myFont);
    gameOver.setFillColor(sf::Shade::Inexperienced);
    gameOver.setStyle(sf::Textual content::Common);
    gameOver.setString("GAME OVER!");
    gameOver.setCharacterSize(65);
    gameOver.setPosition(30, 60);

    sf::Textual content playAgain;
    playAgain.setFont(myFont);
    playAgain.setFillColor(sf::Shade::Inexperienced);
    playAgain.setStyle(sf::Textual content::Common);
    playAgain.setString("Press ENTER to play Once more!");
    playAgain.setCharacterSize(25);
    playAgain.setPosition(80, 235);

    // Clock object to measure total timing
    sf::Clock clock;
    sf::Occasion occasion;

    // Length to regulate animation velocity
    int currentColor = 1;
    float length = float();

    //the whole lot beneath will get copied into the "processSplash" operate
    whereas (window.isOpen()){

        // How a lot time since final loop?
        sf::Time dt = clock.restart();
        length += dt.asSeconds();

        whereas (window.pollEvent(occasion)){
            if (occasion.sort == sf::Occasion::Closed)
                window.shut();

            if (occasion.sort == sf::Occasion::KeyPressed
                && occasion.key.code == sf::Keyboard::Area){
                //shut splash display and begin sport
                /*processSplash();*/
            }
        }

        // Animation length per body (0.1f) reached
        if (length > 0.01f){
          // Restart calculation of the length
          length = 0;

          // Loop via the animation colours
          if (currentColor < 255){
            currentColor += 5;
          } else {
            // Begin from first body if final body reached
            currentColor = 0;
          }
          playAgain.setFillColor(sf::Shade(0, currentColor, 0));
        }

        window.draw(gameOver);
        window.draw(playAgain);

        window.show();
    }
