Graphics / Image too large?
« on: September 09, 2013, 04:12:36 pm »
Hi all,

I was getting a "white sprite" problem.  It shows up fine on one computer and as a white box on another. 
And I thought it was the sf::Sprite, sf::Texture scope, after reading around.    I narrowed it down that the image was too big for the vid card.  The width was 2089 and I cut it back to 2048 and everything was fine.

Anyway, I have a lot of graphics in this game and there will be more.  I've read in the tutorials that it's best to have as few textures as possible, but I did not understand why from the reasoning.  Could someone explain in more simple terms.   Thanks.

Audio / Audio crashes of exit
« on: August 30, 2013, 07:06:04 am »
I've been reading about some issues with Windows XP and sf::Sound, etc.  I don't really understand what's going on...if it's an issue that I have?  Or if the issue was fixed?

My program crashes on exit with a:

The instruction at "0x100453cc" referenced memory ar "0x030cb490". The memory could not be "read".

All I have to put in is this one line to make it crash on exit...
sf::SoundBuffer buf1;

Other than that, the audio works fine.

General / FPS Help
« on: August 29, 2013, 03:43:39 am »
I just started SFML after being an SDL user.   I'm trying to dial in this FPS code.  For some reason the timing is off.

If I set
int FPSQ = 60;
 
I get about 120FPS

To get 60FPS I have to set
int FPSQ = 33;

Graphics / Not a member of sf::Style?
« on: August 27, 2013, 04:57:31 am »
I was messing around with this sample code and got this error...

H:\SFML_Projects\Sample1\main.cpp||In function 'int main()':|
H:\SFML_Projects\Sample1\main.cpp|6|error: 'FullScreen' is not a member of 'sf::Style'|
||=== Build finished: 1 errors, 0 warnings (0 minutes, 0 seconds) ===|


#include <SFML/Graphics.hpp>

int main()
{
    sf::RenderWindow window;
    window.create(sf::VideoMode(800, 600, 32), "A New Window", sf::Style::FullScreen);

    sf::CircleShape shape(100.f);
    shape.setFillColor(sf::Color::Green);

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

        window.clear();
        window.draw(shape);
        window.display();
    }

    return 0;
}
 

If I take out the...    sf::Style::FullScreen  it works fine.

When I type sf::Style::  ...  I get   ...  __Unnamed  as my only option

I'm using codeblocks 12.11 and sfml 2.1

Thanks for any help on this.

General / CodeBlocks libstdc++-6.dll??
« on: August 26, 2013, 09:35:23 pm »
Ok.  I'm getting this error like others on here.
The procedure entry point __gxx_personality_v0 could not be located in the dynamic link library libstdc++-6.dll.

So I've downloaded the  GCC 4.7 TDM (SJLJ) - 32 bits  2.0 version, recompiled and still getting this error.
I tried the 2.1 version as well.

I have Code Blocks 12.11 and using the pre-packaged compiler.
I also noticed in the bin directory of Mingw, I have both of these files:
libgcc_s_sjlj-1.dll
libgcc_s_dw2-1.dll
I don't know if it makes any difference.

Thanks for any possible help.

UPDATE:

Got it fixed.  I forgot to change out the dll files in my project folder when I changed versions.   :-[
