For custom network implementations, you can manually process incoming and outgoing packets using ByteBuffer objects.

• handleIncomingPacket(data, offset, size, srcIP, srcPort): Processes a packet received from a specific IP and port.
• getNextOutgoingPacket(out, offset, size, netAdr, port): Retrieves the next packet that needs to be sent to a specific address and port.

// Example of handling an incoming packet
ByteBuffer buffer = ByteBuffer.allocate(1024);
// ... fill buffer with data ...
boolean handled = SteamGameServerNative.handleIncomingPacket(buffer, 0, buffer.position(), clientIP, clientPort);

Steam Game Server provides several methods to handle user connections, authentication tickets, and session lifecycles.

Authentication Flow:

1. Use getAuthSessionTicket to retrieve a ticket for a user.
2. Use beginAuthSession to start the session.
3. Use endAuthSession to terminate the session.
4. Use cancelAuthTicket if a ticket is no longer needed.

User Verification:

• userHasLicenseForApp(steamID, appID): Checks if a specific user owns a specific application.
• updateUserData(steamIDUser, playerName, score): Updates the user's name and score on the server.

Use the following methods to configure the identity and metadata of your Steam Game Server before logging on. These settings define how the server appears in the Steam server browser and its operational mode.

// Example configuration sequence
SteamGameServerNative.setProduct("MY_PRODUCT_ID");
SteamGameServerNative.setGameDescription("My Awesome Game Server");
SteamGameServerNative.setServerName("Official Server #1");
SteamGameServerNative.setMapName("de_dust2");
SteamGameServerNative.setMaxPlayerCount(32);
SteamGameServerNative.setDedicatedServer(true);

To connect your server to the Steam backend, use either logOn(token) with a specific authentication token or logOnAnonymous() for anonymous access. You can check the connection status using isLoggedOn().

// Anonymous login
SteamGameServerNative.logOnAnonymous();

// Or with a token
SteamGameServerNative.logOn("YOUR_AUTH_TOKEN");

if (SteamGameServerNative.isLoggedOn()) {
    System.out.println("Logged on! SteamID: " + SteamGameServerNative.getSteamID());
}
