« on: February 25, 2019, 07:31:29 pm »

Hi, i 'm posting here because there is no more an active forum for sfemovie library.

Has anyone a working sfemovie lib with 2.5.1 version of SFML?

I built it from source but video (ogv) can not be played. Working just fine with 2.4.2 version of SFML.

thank you

Graphics / How to rotate a texture around the center of a rectangle (solved)

« on: January 02, 2018, 07:58:29 pm »

Hi

i try to figure out how to rotate a square texture (512x512) around a center of a given rectangle (not square).
here is a my code.

void cSprite::render(sf::FloatRect _dstRect, float _angle, sf::Color color)
{
        if (visible)
        {
                float angle =  _angle / 180.f * (float)M_PI;
                float cos = cosf(angle);
                float sin = sinf(angle);
               
                sf::Sprite              sprite;
                sprite.setTexture(*texture);

                float x = _dstRect.width / size.x;
                float y = _dstRect.height / size.y;
               
                sf::FloatRect rect = sprite.getGlobalBounds();
               
                sprite.setPosition(sf::Vector2f(_dstRect.left + _dstRect.width / 2, _dstRect.top + _dstRect.height / 2));
                sprite.setOrigin(sf::Vector2f(rect.width / 2, rect.height / 2));
                sprite.setRotation(_angle);

                sprite.setScale(sf::Vector2f(x, y));

                GAME_MANAGER->getWindow()->draw(sprite);
        }
}
 

i am trying to make a roulette.
the problem is shown in the attached image
thank you for any suggestions

Graphics / Potential bug

« on: October 11, 2017, 09:14:09 pm »

Hi, i am facing a strange issue with timelinefx library. Everything is working just fine in debug until i compiled for release. All effects i used are renderred correct in debug but stretched in release. It may has to do with alpha channel.

I am using the latest sfml version with visual studio 2015.

The guy who port the c++ sfml port for timelinefx library (fradakilla) gave me a solution that is working for release and debug. But the previous code should worked out of the box.

I have create a repro project for everyone who is interested to invastigate this issue.

To work with the fixed code (that is working for both debug and release) uncomment #define FIXED_BY_FRADAKILA

http://www.mediafire.com/file/5v4mx4dgwwgw8k2/TimeLineFx.rar

//working correct both in debug  and release
bool SfmlImage::Load(const char *filename)
{
        _texture = new sf::Texture();

        std::string path = filename;

        sf::Image tmpImage;
        tmpImage.loadFromFile(path.c_str());
        tmpImage.createMaskFromColor(sf::Color::White);

        _texture->loadFromImage(tmpImage);
        _texture->setSmooth(true);

        return true;
}

//working correct only in debug
bool SfmlImage::Load( const char *filename )
{
    _texture = new sf::Texture();

    std::string path = filename;
        assert(_texture->loadFromFile(path.c_str()));

    _texture->setSmooth(true);

    return true;
}
 

thanks in advance
