I am tryng to send a packet of data to another instance of a program on the same PC using UDP Socket but when I update the data and send it the recieve only recievs the intial data. I have gotr my TCP stuff working but i dont know if im missing something on the UDP side. I have followed along with the SFML tutorials for sockets and packets so I'm a little stuck now.
I'm setting up the sockets like this:
sf::TcpSocket serverSocket;
serverSocket.setBlocking(true);
sf::Socket::Status status = serverSocket.connect("127.0.0.1", 1000);
if (status != sf::Socket::Done)
{
//error...
}
while(serverSocket.receive(serverData) != sf::Socket::Done)
{
//error
}
serverData >> playerID >> mapSeed >> recievedPort;
std::cout << recievedPort;
std::cout << mapSeed << "\n";
std::cout << playerID << "\n";
if (playerID == 1)
{
ship.setPosition(100, 100);
sendPort = recievedPort + 1;
bindPort = recievedPort;
}
if (playerID == 2)
{
ship.setPosition(1600, 900);
sendPort = recievedPort - 1;
bindPort = recievedPort;
}
sf::UdpSocket playerSocket;
playerSocket.setBlocking(false);
if (playerSocket.bind(bindPort) != sf::Socket::Done)
{
// error...
}
srand(mapSeed);
for (int i = 0; i < XTILES; i++)
{
for (int j = 0; j < YTILES; j++)
{
tileMap[i][j].setRenderValue(rand() % 20 + 1);
}
}
Which recieves fine and I send my data like this (All the packet data is float):
playerData.x = ship.getPosition().x;
playerData.y = ship.getPosition().y;
playerData.shipOrientation = ship.getOrientation();
playerData.cannonOrientation = ship.getCannonOrientation();
playerData.time = 0;
playerPacket << playerData;
if (playerSocket.send(playerPacket,sf::IpAddress::LocalHost , sendPort) != sf::Socket::Done)
{
// error...
}
sf::IpAddress sender;
if (playerSocket.receive(enemyPacket, sender, bind) != sf::Socket::Done)
{
// error...
}
enemyPacket >> enemyData;
eShip.setPosition(enemyData.x, enemyData.y);
The enemy data recieved is just always the the initial data sent. Am I missing anything?
