Graphics / Overloading SetOrigin.

« on: August 27, 2010, 03:26:40 pm »

Hi

Here another doubt, as I say in my "Getting sprite coords?"

ege::Image inherit from sf::Sprite

I want to overload the SetOrigin method with some like this

SetOrigin(ege::HALIGN x, ege::VALIGN y)

but when I make this, I need to use the SetOrigin of the sf::Sprite (parent class).

What is the better way to make this?

Graphics / Getting sprite coords?

« on: August 27, 2010, 03:21:41 pm »

Hi.

We want to make some "game engine" or framework using SFML, we are beginners programmers on c++ and we will need the entire forum help.

So here is our first request for help.

We make a new class called ege::Image (ege is our namespace for Easy Game Engine), the image inherit from sf::Sprite and the purpose is to make more simple the use of a simple Image. Image have many methods to make the developer life better. One of this method is SetAlign, where the Image can align to screen or to other Image, the align can be LEFT, CENTER, RIGHT, TOP, MIDDLE, BOTTOM, we implement it basically using the Position of Sprite and the Size of it, but that not make a full align when image rotate for example, looking in SFML source code we saw that the method Render of sprite calculate the coords to render the Sprite, there is any way that we can obtain it, direct from sf::Sprite to make a better calculation, we need it for others features to.

Audio / Rare behavior

« on: August 27, 2010, 03:03:27 pm »

Hi.

Making some test with SFML 2 we found some rare behavior using soundbuffer.

When we make a soundbuffer declaration the program not return 0 at the end, it return some negative number.

Just making this:

Code: [Select]


int main()
{
    // Create the main rendering window
    sf::RenderWindow App(sf::VideoMode(800, 600, 32), "SFML Graphics");
   
    sf::SoundBuffer mySound;

    // Start game loop
    while (App.IsOpened())
    {

        // Process events
        sf::Event Event;
        while (App.GetEvent(Event))
        {
            // Close window : exit
            if (Event.Type == sf::Event::Closed)
                App.Close();
        }

        // Clear the screen (fill it with black color)
        App.Clear();

        // Display window contents on screen
        App.Display();
    }

    return EXIT_SUCCESS;
}



I test it on Windows XP Sp3 32bits, Windows 7 32bits, using Codeblock and GCC compiler.
