Network / accepting a socket that has already been accepted

« on: April 15, 2015, 06:20:57 am »

 What happens when I accept a socket that has already been accepted?
will it just continue to return sf::Socket::Done?

listener.accept(socket); //accepted
listener.accept(socket); //??

Network / sending one packet to multiple recipents

« on: January 22, 2014, 04:54:59 am »

I noticed that sf::Tcp::Socket::send  takes a reference to  a sf::Packet , not const sf::Packet
Does this mean that when I send a packet , the contents of the packet get modified so I can't send the same packet to the other clients?
or in code

sf::Packet packet;
packet<<"hi";
for(sf::TcpSocket & s : sockets)
    s.send(packet);//is this ok?

General / Re: using std::enable_if for sf::Packet overloads for enums

Wow thank you so much. Never heard of SFINAE before.
Anyways I think this overload will be a good addition for SFML since enums are frequently used in packets.
Could this be added to SFML when SFML supports c++11?

General / using std::enable_if for sf::Packet overloads for enums

« on: January 20, 2014, 08:28:30 pm »

I'm trying to write a function template for overloading enums with sf::Packet. What did I do wrong?

template <class Enum>
sf::Packet & operator<<(sf::Packet & packet, const typename std::enable_if<std::is_enum<Enum>::value, Enum>::type & t)
{
        return packet << static_cast<typename std::underlying_type<EnumT>::type>(t);
}

template <class Enum>
sf::Packet & operator>>(sf::Packet & packet, typename std::enable_if<std::is_enum<Enum>::value, Enum>::type & t)
{
        typename std::underlying_type<EnumT>::type i;
        packet >> i;
        t = static_cast<Enum>(i);
        return packet;
}

enum Month : sf::Int32
{
    January
}

//doesn't compile
sf::Packet packet;
packet<<January;
Month month;
packet>>month;

I want particles to have random color. How can I do that using UniversalEmitter::setParticleColor?

Go to cmd and type ipconfig or call system("ipconfig") in your program.
Then it will show you the IPv4 address. Use that address.

Network / interpolating

I'm trying to implement entity interpolation explained in this article. I understand that I have to display the game couple frames late, but I have no clue how to translate this into code.

 sf::Packet packet;
 receivePacket(packet);
 packet>>newX>>newY; //now what should I do with this new position?

Network / issues with sf::Int8

« on: December 22, 2013, 05:36:03 am »

I initially thought this was a issue with networking..

int main()
{

        sf::Int8 i = 1;
        std::cout << i;
        std::cin.get();
}

This piece of code prints a smiley face to the console screen, not 1

Network / Re: Example network program doesn't work on school network

« on: October 24, 2013, 08:28:47 pm »

wait...  I got it to work now.

If the exectuable is located in a clouded drive, it doesn't work...
But if the  executable is in a computer's local drive(C: for example), everything suddenly works!
Appreciate the help anyways. Thanks

Do you actually know which kind of antivirus/firewall is running on the PCs? I remember the Comodo Firewall causing rather weird API behavior, even while being deactivated (like crashing QT programs just because they tried to create a socket).

Also wouldn't consider Chrome being some reliable test, because most firewalls will most likely let it pass based on their own whitelists.

This is probably a permission problem... can you use any other network program that isn't installed on the local machine? Or do they also fail to connect?

I downloaded Google Chrome and it works fine.

I can't confirm if your program is working because it closes to fast before I can see the output. I can't even run the  program from command prompt because it's disabled. Howerver, I tried running an old chat program that I made with SFML 2.0 and strangely, it works.
