i have been making a simple server -> client datagramsocket racing game with java, the server has all the logic like hitboxes etc, and the client only process graphics and receive parameters
the thing is i want to use WASM to play my game in the browser (both server and client), and i learned that i need to use websockets (tcp), the i learned that i need to use webrtc for udp (that what i use here)
i dont know how it works and how can i remake my server (i dont think its much of a replacement, so I guess I have to change the way I send and receive messages)
look you have my server.java if that serves as reference:
package online;
import java.io.IOException;
import java.net.*;
import java.util.ArrayList;
public class Server extends Thread {
public static DatagramSocket socket;
private int port = 5555;
private boolean end = false;
private final int MAX_CLIENTS = 8;
private int connectedUsers = 0;
public static ArrayList<User> users = new ArrayList<User>();
private NetManager netManager;
public String move = "";
public int clientIndexed = 0;
public Server(NetManager netManager) {
this.netManager = netManager;
try {
System.out.println("server iniciado en el puerto "+port);
socket = new DatagramSocket(port);
} catch (SocketException e) {
throw new RuntimeException(e);
}
}
@Override
public void run() {
Runtime.getRuntime().addShutdownHook(new Thread(() -> {
System.out.println("Server shutting down");
this.pingEveryone("serverClosed");
end = true;
}));
do {
DatagramPacket packet = new DatagramPacket(new byte[1024], 1024);
try {
socket.receive(packet);
processMessage(packet);
} catch (IOException e) {
throw new RuntimeException(e);
}
} while (!end);
}
public void pingEveryone(String message) {
for(User user : users) {
sendMessage(message, user.getIp(), user.getPort());
}
}
private void processMessage(DatagramPacket packet) {
String message = (new String(packet.getData())).trim();
// System.out.println(message);
String[] parts = message.split("\\$");
switch (parts[0]) {
case "connect":
if(users.size() >= MAX_CLIENTS) {
sendMessage("serverfull", packet.getAddress(), packet.getPort());
} else {
sendMessage("connected;"+connectedUsers, packet.getAddress(), packet.getPort());
this.connectedUsers++;
User newUser = new User(parts[2], packet.getAddress(), packet.getPort());
users.add(newUser);
netManager.placeNewPlayer(connectedUsers, parts[1]);
}
break;
case "move":
move = parts[1];
clientIndexed = searchUser(packet);
netManager.moveCar(parts[1], searchUser(packet));
break;
case "disconnect":
int index = searchUser(packet);
users.remove(index);
netManager.deleteRacer(index);
this.connectedUsers--;
break;
}
}
private int searchUser(DatagramPacket packet) {
int i = 0;
int indexUser = -1;
while (i < users.size() && indexUser == -1) {
User user = this.users.get(i);
String id = packet.getAddress()+":"+packet.getPort();
if(id.equals(user.getId())) {
indexUser = i;
}
i++;
}
return indexUser;
}
public void sendMessage(String message, InetAddress ipDestination, int port) {
byte[] datosByte = message.getBytes();
DatagramPacket packet = new DatagramPacket(datosByte, datosByte.length, ipDestination, port);
try {
socket.send(packet);
} catch (IOException e) {
throw new RuntimeException(e);
}
}
public void finish() {
System.out.println("me voy a la mierda");
pingEveryone("serverClosed");
this.end = true;
socket.close();
this.interrupt();
}
}
and its that, where do i start, what i need to know, dont be rude I learned about webrtc a few days ago and I dont even know where to start looking at documentation or tutorials (to avoid getting banned, Im not asking about libraries, but rather where to start or for advice)
thanks!!!!
