There is a server that creates an array of integers and puts them in a package, and two clients that immediately after connecting receive a package with an array of integers and use it to generate a game map.
The problem is that if both clients are connected to localhost, then they receive the same data, when connected from different devices, clients receive different data.
server.cpp
sf::UdpSocket socket;
if (socket.bind(54000) != sf::Socket::Done) {
return -1;
}
std::cout << "Server is listening on port 54000" << std::endl;
const sf::Uint16 side = 10;
sf::Uint16 level[side * side];
for (int i = 0; i < std::size(level); i++) {
int start = 0;
int end = side;
int x = rand() % (end - start + 1) + start;
if (x < 3)
level[i] = 1;
else
level[i] = 0;
}
....
sf::Packet packet;
packet << level[side * side];
socket.send(packet, client1Ip, client1Port);
client.cpp
const sf::Uint16 side = 10;
sf::Packet packet;
if (socket.receive(packet, serverIp, port) != sf::Socket::Done) {
std::cerr << "Error receiving data" << std::endl;
return -1;
}
sf::Uint16 level[side*side];
packet >> level[side*side];
What could be the reason for this behavior and how can it be fixed?
