Audio / When the first sound ends, so does the second.

« on: December 13, 2013, 02:58:36 pm »

Are there any obvious mistakes I'm making here?

Noteworthy: m_Sounds and m_SoundBuffer are static private member variables. m_Sounds is a vector and m_SoundBuffer is a map.

void ResourceManager::Update()
{
    for (unsigned int i = 0; i < m_Sounds.size(); ++i)
    {
        std::cout << "Sound " << i << " = " << m_Sounds[i].getPlayingOffset().asSeconds() << "\n";

        if (m_Sounds[i].getStatus() == sf::Sound::Stopped)
        {
            std::cout << i+1 << " / " << m_Sounds.size() << " was Killed\n";
            m_Sounds.erase(m_Sounds.begin() + i);
            continue;
        }
    }
}

sf::SoundBuffer& ResourceManager::soundBuffer(std::string fileName)
{
        std::map<std::string, sf::SoundBuffer>::iterator it = m_SoundBuffers.find(fileName);

        if (it == m_SoundBuffers.end()) //not found
        {
                sf::SoundBuffer sb;
                assert(sb.loadFromFile("audio/" + fileName + ".wav"));
                std::cout << "SoundBuffer Loaded: " << "audio/" << fileName << ".wav\n";
                m_SoundBuffers.insert(std::make_pair(fileName, sb));
                return m_SoundBuffers.find(fileName)->second;
        }

        return it->second;
}

void ResourceManager::sound(std::string fileName)
{
    sf::Sound s(this->soundBuffer(fileName));
    m_Sounds.push_back(s);
    m_Sounds.back().play();
}
 

case sf::Event::MouseButtonPressed:
{
    ResMan.sound("fireworks");
    break;
}
 

only when I close the RenderWindow do I get the segmentation fault

General discussions / Any open source examples of the networking library used in a game?

« on: December 13, 2013, 10:11:22 am »

I've had issues using SFML's networking part of the library in the past and want to create a multiplayer game, are there any open-source games made with SFML that use the SFML networking library that I could take a look at?

Graphics / SFML 2, window styles gone?

« on: September 08, 2012, 01:48:18 pm »

I don't want my window to be resized, but there is no sf::Style::xyz, they are all gone. I can't find any documentation on it either, have they been removed or..?

Graphics / Crashes on RenderWindow

« on: August 09, 2012, 05:28:43 pm »

I've tried 're-installing' SFML2 without any luck, it was working for me before. however when cmake failed to compile SFML2 this started happening, I removed SFML completely from the MinGW folder and the folder I used to use for linking, downloaded sfml2-rc, placed it in a folder outside of MinGW, linked it normally, added the .DLL's and this is still happening.

Ideas?

Oh, and the examples work fine.

Network / Help with sending/receiving packets on LAN/WAN

« on: August 05, 2012, 01:58:28 pm »

When I run this code on myself, it works fine, but when I run it on two computers and try to connect to each other, both can send but only one can receive, what's wrong? it's not a problem with the router/firewalls, I've set it up properly and it shouldn't affect the LAN anyway.

sf::IpAddress ip;
unsigned short int port = 2222;
void client()
{
    sf::TcpSocket clientSocket;
    sf::Packet clientPacket;

    clientSocket.connect(ip, port);

    while (true)
    {
        std::string send;
        std::getline(std::cin, send);
        clientPacket << send;
        clientSocket.send(clientPacket);
        clientPacket.clear();
    }
}

void server()
{
    sf::TcpListener listener;
    sf::TcpSocket serverSocket;
    sf::Packet serverPacket;

    listener.listen(port);
    listener.accept(serverSocket);
    while (true)
    {
        std::string receive;
        serverSocket.receive(serverPacket);
        serverPacket >> receive;
        std::cout << receive << "[received]" << std::endl;
        serverPacket.clear();
    }
}

int main()
{
    std::cin >> ip;
    std::cin.clear();
    std::cin.ignore();
    sf::Thread cThread(client);
    sf::Thread sThread(server);
    cThread.launch();
    sThread.launch();
}

Graphics / Key Released?

« on: March 15, 2012, 10:21:04 pm »

I'm trying to get a functioning ping pong game working in sfml2, despite reading and re-reading the documentation, I can't figure out how to find if a key was released, so that I can stop individual paddles from moving.

Code: [Select]

switch (Event.type)
{
case sf::Event::Closed:
Window.close();
break;
            case sf::Event::MouseButtonPressed:
                Ball.setPosition(sf::Mouse::getPosition(Window).x - Texture1.getWidth() / 2, sf::Mouse::getPosition(Window).y  - Texture1.getHeight() / 2); // test, disable for release
                break;
            case sf::Event::KeyPressed:
                if (sf::Keyboard::isKeyPressed(sf::Keyboard::W))
                    {IsMovingUp1 = true; IsMoving1 = true;}
                else if (sf::Keyboard::isKeyPressed(sf::Keyboard::S))
                    {IsMovingUp1 = false; IsMoving1 = true;}

                if (sf::Keyboard::isKeyPressed(sf::Keyboard::Up))
                    {IsMovingUp2 = true; IsMoving2 = true;}
                else if (sf::Keyboard::isKeyPressed(sf::Keyboard::Down))
                    {IsMovingUp2 = false; IsMoving2 = true;}
                break;
            case sf::Event::KeyReleased: // need to figure out a way of knowing which key it was so I don't stop both paddles
                IsMoving1 = false;
                IsMoving2 = false;
                break;
default:
break;
}

General / Can't compile code, 'class sf::X' has no member named 'Y'

« on: March 12, 2012, 11:16:34 pm »

I've recently moved to ubuntu from windows, in windows I could get SFML working but I can't seem to get it working in ubuntu, I'm pretty sure I made it [sfml 2.0] properly so it must be a linker/compiler problem.

I'm using codeblocks.

I'm trying to compile this:

Code: [Select]

#include <SFML/Graphics.hpp>

int main()
{
sf::RenderWindow Window(sf::VideoMode(800, 600, 32), "SFML Sample Application");

while (Window.IsOpen())
{
sf::Event Event;
while (Window.PollEvent(Event))
{
switch (Event.Type)
{
case sf::Event::Closed:
Window.Close();
break;
default:
break;
}
}

Window.Clear(sf::Color(0, 255, 255));
Window.Display();
}

return 0;
}



with static libraries, in settings>compiler>global compiler>search directories>compiler I have "/home/z/Programming/sfml2/include" and in settings>compiler>global compiler>search directories>linker I have "/home/z/Programming/sfml2/lib", in settings>compiler>global compiler>compiler settings>#defines I have "SFML_STATIC".

then in my project build options, I have this in debug>linker settings>link libraries

Code: [Select]


sfml-graphics-s-d
sfml-audio-s-d
sfml-window-s-d
sfml-network-s-d
sfml-system-s-d


and I have this in release>linker settings>link libraries

Code: [Select]


sfml-graphics-s
sfml-audio-s
sfml-window-s
sfml-network-s
sfml-system-s


Am I missing something? these are the errors I'm getting:
