How to draw a sprite on top of another?
« on: May 23, 2012, 12:13:00 am »
    while (window.isOpen())
    {
        //Processes events
        sf::Event event;

        //Fills Event with data
        while(window.pollEvent(event))
        {
            switch(event.type)
            {
                case sf::Event::Closed:
                window.close();
                break;
                default:
                break;
            }
        }
        window.clear();
        window.draw(bgs);
        window.display();
        xTurn();
    }

void xTurn()
{
    bool xturn = true;

    while(xturn)
    {
    if (sf::Mouse::isButtonPressed(sf::Mouse::Left))
    {
        sf::Vector2i mousePosition = sf::Mouse::getPosition(window);

        if((mousePosition.x < 200 && mousePosition.y < 200)
               && sf::Mouse::isButtonPressed(sf::Mouse::Left))
           {
        X.setPosition(25, 20);
        window.draw(X);
        std::cout << "hi";
        xturn = false;
           }

    }
    }

There's part of my main method and my whole xTurn code. Essentially when you left click, I want the sprite X to be printed. Also, that buttonispressed seems to activate multiple times (hi prints out 30+ times as opposed to just once).

How do I go about doing this?

Thanks.

You have to put the Xturn() call between your window.clear() and your window.display() call. Otherwise the draw call inside your xturn() function will never be shown in the window. Sf::mouse::isbuttonpressed is true as long as the button is pressed, so you are likely to have 30+ executions even if you only press the mouse button for a short time.

The thing is, its going to be tic tac toe game. I wanted to load the background (bgs) and afterwards every time someone clicks a certain area, an x or o appears. Wouldn't the bgs not display until after xturn ends?

Nevermind, I figured everything out.

Here's the Tic Tac Toe app: http://d.pr/f/gh1L

Credit goes to EnigmaticFellow (http://en.sfml-dev.org/forums/index.php?topic=6953.0) for supplying the Grid, X, and O images.

I used none of the code from that project, but the images supplied in that pack were too perfect to pass up.

Enjoy!
