SFML projects / Re: SFNUL

« on: December 17, 2015, 11:39:42 am »

After I read on internet on the broadcast ip address and how to calculate it I tested on the precalculated broadcast ip address of my ip address and worked . Now the question is: what is the best way to get the local ip and mask? Should I include and use asio or is a better way? ( If asio is the way, should use the version that come with SFNUL? I found in the SFNUL's cmake file that the include path is included but leave out the sources, or maybe he is just a dependency of a dependency).

SFML projects / Re: SFNUL

Nice library. I decided to use SFNUL in my new tableboard multiplayer mini game, but I need some help. I firstly used SFML and then decided to use SFNUL because of the relief of code the library offer. In my LAN server overview window I used sf::UdpSocket with sf::AnyPort to send a package to all servers on network using sf::IpAddress::Broadcast and the port of the server, then the server would send back the a package so the client would know that at that ip is a server. Now that I switched to SFNUL I don't know how to do same thing. The Bind() function require a ip address and a port, not just the port and also how to send a message to the network because I can't find a function to get the broadcast ip address( EDIT: I think it is 0.0.0.0).

Graphics / Re: Text.GetGlobalBounds() is lying to me!

Another method would be:

text.setOrigin(text.getLocalBounds().left, text.getLocalBounds().top);

You can also use a fragment shader.

I don't know if I understood the problem but it would not be easier to put the sfml window( the loop) in a separated thread and then call it.

Hello I have a problem: I'm getting high CPU usage with this code and I don't know what I'm doing wrong:

#include <SFML/Graphics.hpp>

int main()
{
        sf::RenderWindow window({800, 600}, "My window");

        sf::Time m_timePerFrame = sf::seconds(1.0f / 60.0f);
        sf::Time m_timeSinceLastUpdate = sf::Time::Zero;

        sf::Clock m_clock;
    while (window.isOpen())
    {
                sf::Time m_frame = m_clock.restart();
                m_timeSinceLastUpdate += m_frame;

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

                        m_timeSinceLastUpdate -= m_timePerFrame;
                }

                window.clear();

                window.display();
    }

    return 0;
}

If instead of all the manual frame limiting I use window.setFramerateLimit(60) everything works fine - 0% cpu usage, but with my above code I'm getting high CPU usage. Please some help.

I responsed here. For the example for android, the ABI is set to armeabi-v7a( jni/Application.mk)  so you need to be carefully what arhitecture the phone/simulator has. ( yes, you can add more/change values to the ABI).

From what I read you should take a good C++ book and read it. For what you want to make you don't need threads and can do everything in the main thread.

After you compiled SFML for Android( here) just go in the folder of the sfml example and run ndk-build and then open normally the project in Eclipse or Android Studio.

Texture is destroyed at the final of loop. Try to put everything between .clear and .display out of the main loop and keep only

window1.draw(sprite1);
