SFML C++ Basis

[Ellie]

I'm posting this here because it's useful to me, so it might be useful to others.

In a visual C++ project with SFML in it, this is your "main", equivalent to the RGSS main.

<div class="c" id="{CB}" style="font-family: monospace;"><ol><span style="color: #339933;">#include <SFML/Graphics.hpp>

<span style="color: #339933;">#include <SFML/Audio.hpp>

 

<span style="color: #993333;">int main()

{

    // the game object

    Game game;

 

    // Create main window

    sf::<span style="color: #202020;">RenderWindow App(sf::<span style="color: #202020;">VideoMode(<span style="color: #cc66cc;">800, <span style="color: #cc66cc;">600), "Fantasia");

 

    // Create a clock for measuring the time elapsed

    sf::<span style="color: #202020;">Clock Clock1;

    

    // Start game loop

    <span style="color: #b1b100;">while (App.<span style="color: #202020;">IsOpened())

    {

        <span style="color: #993333;">float delay=Clock1.<span style="color: #202020;">GetElapsedTime();

        // Process events

        sf::<span style="color: #202020;">Event Event;

        <span style="color: #b1b100;">while (App.<span style="color: #202020;">GetEvent(Event))

        {

            // Close window : exit

            <span style="color: #b1b100;">if (Event.<span style="color: #202020;">Type == sf::<span style="color: #202020;">Event::<span style="color: #202020;">Closed)

                App.<span style="color: #202020;">Close();

            

            // Key press

            <span style="color: #b1b100;">if (Event.<span style="color: #202020;">Type == sf::<span style="color: #202020;">Event::<span style="color: #202020;">KeyPressed)

            {

                <span style="color: #b1b100;">if(Event.<span style="color: #202020;">Key.<span style="color: #202020;">Code == sf::<span style="color: #202020;">Key::<span style="color: #202020;">Escape)// Escape key : exit

                {App.<span style="color: #202020;">Close();}

                <span style="color: #b1b100;">else // Pass key press to game

                { game.<span style="color: #202020;">keyHandler(Event.<span style="color: #202020;">Key.<span style="color: #202020;">Code); }

            }

            

        }

 

        //play the game every tenth of a second

        <span style="color: #b1b100;">if(delay><span style="color: #cc66cc;">0.1) {

            game.<span style="color: #202020;">play();

            Clock1.<span style="color: #202020;">Reset();

        }

 

        //Draw the game

        game.<span style="color: #202020;">draw();

 

        // Finally, display the rendered frame on screen

        App.<span style="color: #202020;">Display();

    }

  

 

    <span style="color: #b1b100;">return EXIT_SUCCESS;

 

}

 

Provided by my uni and slimmed down to remove unnecessary bits.

All you need to do now is create a Game class, which has the functions:

draw();
keyHandler(keyCode);
play();

Consider play to be equivalent to RGSS's "refresh".
