Network / Packets : Vector Transfers and sf::objects

« on: April 29, 2020, 03:54:26 pm »

Hello,

I feel like I'm  kind alone on this forum but I still try

I have two question :

1- Is it possible to send a structure (or whatever) with vectors in it by packet >> ?
Like this :

typedef struct BMMaps BMMap;
        struct BMMaps
        {
            std::string nom = "Map par défaut" ;
            int background = 0;
            std::vector<Plateforme> plateformes;

        };
inline sf::Packet& operator <<(sf::Packet& packet, const BMMap& m)
{
    return packet << m.nom << m.background << m.plateformes ;
}
inline sf::Packet& operator >>(sf::Packet& packet, BMMap& m)
{
    return packet >> m.nom >> m.background >> m.plateformes ;
}
 

This doesn't work of course, and when I try to send the size of the vector then every element in it with a for(i=0; i < myVector.size() ; i++) , it gives me an error as well .

2- Is it possible to send sf::objects in packet ?
I'd like to send a lot of sf::RectangleShape , or CircleShape, but this :

sf::RectangleShape r;
sf::Packet p << r;
 

doesn't work. I mean, I guess sfml made its own packet object compatible with its own others objetcs ?


Thanks for your help,

Network / Non-blocking UDP socket doesn't receive any data

« on: April 20, 2020, 09:33:27 am »

Hi, I'm wondering why when I put my socket in non-blocking I don't receive anything ?

When I send data to this socket, the following code works :

broadcastSocket.setBlocking(true);
            broadcastSocket.bind(52001);
            if(broadcastSocket.receive(udpp,ip,port) == sf::Socket::Done)
            cout << "Data received" << endl;

but this one doesn't :

broadcastSocket.setBlocking(false);
            broadcastSocket.bind(52001);
while(1)
{
            if(broadcastSocket.receive(udpp,ip,port) == sf::Socket::Done)
            cout << "Data received" << endl;
}

Thanks for your help !
