System / [2.0] sf::Thread and sf::RenderWindow::pollEvent()

« on: January 08, 2013, 06:47:03 am »

Is it possible to utilize a thread mainly for handling the close button of the application window? My current code doesn't seem to work. The window just freezes as if I wasn't checking for events, although the thread is running.

#include <SFML/Graphics.hpp>
//#include <game.hpp>

sf::RenderWindow appWindow( sf::VideoMode( 800,600 ),"Fox" );

void AppEvents()
{
    while( appWindow.isOpen() )
    {
        sf::Event event;
        while( appWindow.pollEvent( event ) )
        {
            if ( event.type == sf::Event::Closed )
                appWindow.close();
        }
    }
}

int main(int argc, char* argv[])
{
    //Player player;
    //Room room("res/rooms/MainMenu/room.xml");
    sf::Thread appEvents(&AppEvents);
    appEvents.launch();
    appEvents.wait();
    return EXIT_SUCCESS;
}

Any body have an idea why that might be?

General / Trouble at Runtime

« on: December 23, 2012, 09:42:53 pm »

Hi. I've followed your tutorial for SFML-2.0 RC with Code::Blocks. I get this segmentation fault:

#0 6E182B85     sf::VideoMode::VideoMode(this=0xc8, modeWidth=200, modeHeight=32, modeBitsPerPixel=2) (D:\developpement\sfml-master\src\SFML\Window\VideoMode.cpp:50)
#1 00401418     main(argc=1, argv=0x372d80) (C:\Users\Nicolas\Documents\Projects\Fox 3\main.cpp:5)
 

I found that this issue was already reported here (http://en.sfml-dev.org/forums/index.php?topic=9598.0) with no answer. Does anybody have any idea on how to fix this?

I'm on an AMD Radeon HD 6850 if that helps.

Graphics / Extra pixels drawn

« on: December 06, 2012, 03:43:57 am »

When I try drawing anything (SFML-1.6) via sf::RenderWindow::Draw() it semi-randomly comes up with extra pixels over the image that I loaded.

Example:


This occurs for most images I try. I have a feeling SFML adds some sort of effect or blur to images when they are drawn. Else, what should I do to fix it?

Graphics / Incompatibility with sf::Image and stl::list??

« on: October 14, 2012, 06:40:00 am »

Does anyone know if there is an incompatibility here? My animation class runs smoothly every time, but when I try to automate the process of reading several animations by queuing them in an stl::list, they don't show on-screen.

I'm positive the issue is something like this. The function I'm calling to draw it returns the sf::Sprite of the current frame, but it isn't showing anything. The program doesn't crash or anything either, so I'm thinking the Image doesn't stay in memory when it's in a list.

Anybody know anything about this?

Graphics / Crash when Setting Sprite Values

« on: July 28, 2012, 10:54:03 pm »

void sursprite::Add()
{
    main.SetSubRect( sf::IntRect( aX[aIndex], aY[aIndex], ( w + aX[aIndex] ), ( h + aY[aIndex] ) ) );
    sprite_queue.push_back( *this );
}

At line 3 in the above function, my program crashes. aX & aY are equal to zero. w & h are equal to 32.
