Feature requests / Fill method for Image ?

« on: June 27, 2016, 06:36:13 pm »

Maybe it's a good idea to add a method to sf::Image which fills the specified region(or whole) image with specified Color ?

General / Is my game loop is correct ?

« on: November 27, 2015, 01:20:13 pm »

The code below worked correctly(and even with different framerates) - but I need to know - is everything ok ?(e.g -  order of calling functions or delta time calculation). Is there is some room for improvements ?

       
              Clock clock;
                Time accumulator = Time::Zero;
                Time updateRate = seconds(1.0f / 60.0f);
                Time dt = Time::Zero;
                Time fpsTime = Time::Zero;

                while (m_pWindow->isOpen())
                {
                        ProcessEvents();

                        accumulator += dt;

                        while (accumulator > updateRate)
                        {
                                update_state.DeltaTime = 1.0f / 60.0f;

                                accumulator -= updateRate;

                                Update(update_state);
                        }

                        Render(draw_state);

                        dt = clock.restart();

                        // calculating FPS
                       
                        fpsTime += dt;

                        static unsigned frameCounter = 0;

                        if (fpsTime >= seconds(1.0f)) // calculate FPS only one time per second
                        {
                                m_FPS = frameCounter;
                                fpsTime = Time::Zero;
                                frameCounter = 0;
                        }
                        else
                        {
                                ++frameCounter;
                        }
                }

General discussions / A few questions to main developers.

« on: March 01, 2015, 09:10:59 am »

Hello, I'm new user of SFML and have few questions..
1. Will SFML internals be rewritten to OpenGL Next(when it is released)?
2. Will SFML get DDS(Direct Draw Format) support for images ?
3. The core API will get changes or it is frozen for backward compatibility forever(like whole C++)?
4. Will basic math routines such as clamp function be implemented or its not "simple" ?
