General / Re: SFML issue Code::Blocks and static libraries

« on: August 04, 2014, 09:14:00 am »

You don't need this tutorial. If you don't have lastest realase of C::B, you should download it.
In Code::Blocks 13.12 you have updated SFML Project, you just need to select
New Project...->SFML Project->sfml 2.0 and give a path to sfml 2.1 main folder.
That's all.

Yes, I did.
EDIT: New informations, I setted project to dynamic libs and indeed it's  working without glResetStates().

I compiled sources (CMAKE + C::B), created new sfml project in C::B, tried and I have the same problem as before (without resetGLStates()). Maybe I'm doing something wrong, but I didn't want to mislead anyone. 
Or sources from this page, is not what I had to compile: http://sfml-dev.org/download.php ? 
If I must get it directly from github, then I'll try again. In edit I'll write if it's working or not.

Thanks Nexus, good to know about RAII .
EDIT: First video clip is without glResetStates(), second with.

It's the same as in first post, but before app.clear() line, I wrote app.resetGLStates() as Alex proposed.
EDIT: I edited first post.

Try to reset the openGL states before you are drawing/clearing the rendertexture. (I have the same issue)

It's working! 
Thanks Alex.

Worst.texture.ever.

Just Code::Blocks SFML project, for test.

Graphics / sf::RenderTexture problem

Is hope it is not normal for sf::RenderTexture:

Can I fix it somehow, or what I'm doing wrong ?

Graphics Card: Radeon HD 5570
Lastest drivers.

#include <SFML/Graphics.hpp>

int main()
{
    sf::RenderWindow app(sf::VideoMode(800,600),"RT Test");
    // Load a sprite to display
    sf::Texture texture;
    if (!texture.loadFromFile("cb.bmp"))
        return EXIT_FAILURE;
    sf::Sprite sprite(texture);

    sf::RenderTexture rt;
    rt.create(800,600);

    sf::Sprite surface(rt.getTexture());

        // Start the game loop
    while (app.isOpen())
    {
        // Process events
        sf::Event event;
        while (app.pollEvent(event))
        {
            // Close window : exit
            if (event.type == sf::Event::Closed)
                app.close();
        }
        sprite.move(0.1f,0);
        // app.resetGLStates(); // with this, all work
        rt.clear(sf::Color::White);
        rt.draw(sprite);
        rt.display();


        // Clear screen
        app.clear();

        // Draw the sprite
        app.draw(surface);

        // Update the window
        app.display();
    }

    return 0;

I read the tutorial again but more precisely, and:
Okay... sorry for my stupidity. 
Now it's working, as should  . Sorry for taking your valuable time.
Now I can create simple particle system for my games. 
Thanks, and have a good day.

Why do you ask for SPARK then?

It was just example. 
Ok, thanks I'll take a look at Thor.
I created a particle system, based on sf::Quads, but I wanted to know, how can I blur my particles like in yt viedo, or texture it. I'm asking, beacuse when I draw my particles with Gaussian Blur shader, my quads are just vanishing. When I texture it, one quad is one pixel so to create something like on the screen:
http://oi61.tinypic.com/104ntc4.jpg
I must to create width*height*4 vertices for one big textured particle, right ?
Generally, I want to have two options. Texture particle, and create an effect with that, or just lay on particles an shader (for example blur, like in this video: ).
So to create (textured) particle system based on vertices, is something like texture_width*texture_height*4*particle_count vertices a good idea ? That's my final question.  And it's not my first time, when I'm using particles, but I've never tried to create any particle system by myself.

Oh, but i don't want to use anything. 
I knowed about thor long ago, but I want to create particle system by myself.
And like I wrote:

On the demo, we can see fire particles:
http://oi61.tinypic.com/104ntc4.jpg
It's an texture, but how can I make something like that ?
I want quad particles, which I can texture like that, when it's needed.
What should I use ?

EDIT: It's can be something like that too:

Quads + perlin noise and blur.
