Graphics / sf::RenderTexture and CPU 50%

« on: December 31, 2013, 02:43:49 am »

Hello
When you add in the draft RenderTexture, CPU immediately increased to 50%.

    sf::RenderWindow window(sf::VideoMode(800, 600), "SFML");
    window.setVerticalSyncEnabled(true);

    sf::RenderTexture rendTexture;
    rendTexture.create(100, 100);

    while (window.isOpen())
    {
        sf::Event event;
        while(window.pollEvent(event))
        {
            switch(event.type)
            {
                case sf::Event::Closed:
                    window.close();
                    break;
                case sf::Event::KeyPressed:

                    if(sf::Keyboard::isKeyPressed(sf::Keyboard::Escape))
                        window.close();
                break;

                default:
                break;
            }
        }

        rendTexture.clear();      
        rendTexture.display();  

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

Tell me, is this normal?

Graphics / sf::Texture and sf::RenderTexture.getTexture

« on: September 13, 2013, 05:14:39 am »

Hello
There is such a code

    sf::Sprite sprite_1;
    sf::Texture texture;
    texture.loadFromFile("d:\\1.png");
    sprite_1.setTexture(texture);

    sf::RenderTexture renderTexture;
    renderTexture.create(96, 96);
    renderTexture.clear(sf::Color(255, 255, 255, 0));
    renderTexture.draw(sprite_1);
    renderTexture.display();

    sf::Sprite sprite_2;
    sprite_2.setTexture(renderTexture.getTexture());
    sprite_2.setPosition(97.f, 0.f);

....

   Window.clear(sf::Color(128, 128, 128));
   Window.draw(sprite_1);
   Window.draw(sprite_2);
   Window.display();

 

Please explain why little difference between pictures. (the shadow)




Sorry for the English.

Graphics / Dynamic size RenderTexture

« on: June 03, 2013, 11:00:05 am »

How can I dynamically change the size RenderTexture?
Is this possible?

sf::RenderTexture rTexture;
rTexture.create(100.0f, 100.0f);
...
...
rTexture.create(200.0f, 200.0f);
 

or better not?

Graphics / Text and sprite in the guise

« on: March 02, 2013, 03:00:41 am »

Hello!
Tell me how can I do?
To moving text or sprite was visible like a mask. For the red box could not see them.


The result should look like this:

Graphics / sf::RenderTexture Flipped

« on: February 11, 2013, 06:19:51 am »

Hello!
Raised two questions on the same topic

Here is the code

#include <SFML/Graphics.hpp>

int main()
{
    sf::VideoMode VMode(800, 600, 32);
    sf::RenderWindow Window(VMode, "SFML 2", sf::Style::Close);


    sf::RenderTexture texture;
    if (!texture.create(500, 500))
     return -1;

    sf::Text text;
    text.setString("TEST");
    text.setPosition(0.0f, 0.0f);
    text.setColor(sf::Color(255, 0, 0));

    sf::Texture texture_img;
    texture_img.loadFromFile("image.png");
    sf::Sprite sprite_image;
    sprite_image.setTexture(texture_img);

    while(Window.isOpen())
    {
        sf::Event Event;
        while(Window.pollEvent(Event))
        {
            switch(Event.type)
            {
                case sf::Event::Closed:
                    Window.close();
                    break;
                case sf::Event::KeyPressed:
                    if(sf::Keyboard::isKeyPressed(sf::Keyboard::Escape))
                        Window.close();
                    break;
                default:
                    break;
            }
        }

        texture.clear(sf::Color::Blue);
        texture.draw(text);
        texture.draw(sprite_image);
//        texture.display();

        Window.clear(sf::Color(128, 128, 128));

        sf::Sprite sprite(texture.getTexture());
        Window.draw(sprite);
        Window.display();
    }
    return 0;
}

1. Why texture turns upside down, and what you can do

2. When the string / / texture.display (); longer displayed texture that I do not?

Hello!
Sorry for bad English.
There is such code, http://wiki.videolan.org/LibVLC_SampleCode_SDL the video display on the surface SDL. Is it possible to implement this in SFML?
