Passing it to the function as a reference didnt work, but using a global variable did

Why do you have

loadingThread.Wait();

so

Code: [Select]

bool threadRunning = false;

void loadFiles()
{
 threadRunning = true
    ...
 threadRunning = false

sf::Thread loadingThread( &loadFiles);
loadingThread.Launch();

while( threadRunning)
{
    Animate and draw loading screen

I want to use a thread to load all the assets and while this is happening animate a loading screen.

The way I thoughht I would do it is:

Code: [Select]


void loadFiles()
{
    ...
}

sf::Thread loadingThread( &loadFiles);
loadingThread.Launch();

while(loadingThread.isRunning)
{
    Animate and draw loading screen
}


The problem is that there is no way to find out if the thread is still running, it there any way to do this?

Graphics / Weird visual glitches after latest SFML2-port

This used to happen when having smooth images set and using a tile set, might be your case
Try disableing image smoothing

Graphics / Game crashes on Display

Hmm, not sure if that worked or not as implementing the drawing before setting te origin created a different bug, however making a pointer to the menu class instead of not using a pointer has fixed everything.

Might be worth looking at tho

It seems text needs to be drawned before you can use getRect

Figured out its to do with when I set the origin of the text
I think i do it right but im not sure

Code: [Select]


TitleText.SetOrigin(TitleText.GetRect().Width / 2, TitleText.GetRect().Height / 2);
    NewGameText.SetOrigin(NewGameText.GetRect().Width / 2, NewGameText.GetRect().Height / 2);
    OptionsText.SetOrigin(OptionsText.GetRect().Width / 2, OptionsText.GetRect().Height / 2);
    QuitText.SetOrigin(QuitText.GetRect().Width / 2, QuitText.GetRect().Height / 2);

So after the last thread in which I was having an error with openGL I have starte to use just SFML and 2D
But now its breaking with this.

I have

Code: [Select]


std::cout << "draw sfml" << loop << std::endl;
            Game::DrawSFML();
std::cout << "display" << loop << std::endl;
            // Display window contents on screen
            App.Display();
            std::cout << "end" << loop << std::endl;

            loop++;


which gives

sqwitch0
menu0
draw sfml0
display0
[richy@fedoraLt Release]$

Im going to look through the SFMl source and my code to check if i have maybe created the window incorrectly

Graphics / Textures and RenderTextures broken

Just tried using valgrind thought this might give some more details about the porblem

Code: [Select]

Seems this is the problem, just tried something and it crashed with any drawable not just textures/sprites

Window / Hoow do I set the position/other stuff before creation?

« on: August 30, 2011, 05:53:48 pm »

Basically I currently use

Code: [Select]

Game::isOpenGLSetup = Game::setupOpenGL();
    App.SetFramerateLimit(GlobalSettings::globalSettings.getFrameRateLimit() );
    App.ShowMouseCursor(false);

    sf::VideoMode desktopVM = sf::VideoMode::GetDesktopMode();
    App.SetPosition( (desktopVM.Width/2.0) - (App.GetWidth()/2.0) , (desktopVM.Height/2.0) - (App.GetHeight()/2.0)  );

    smView = sf::Vector2i(800,600 );
    winView = sf::Vector2i(GlobalSettings::globalSettings.getWinWidth() , GlobalSettings::globalSettings.getWinHeight() );

    App.Show(true);

Where App.create... gets called in setupOpenGL() but this means that the window shows and then after moves looking a bit ugly.
But if I set it before create then it doesnt do anything.
Im not sure if calling create resets all the values or something
