BungeeCord is a proxy server for Minecraft, primarily used for connecting multiple Minecraft servers together. It allows players to seamlessly switch between different game modes or server instances without disconnecting, providing a unified experience across multiple Minecraft servers.

Pros

• Enables server networks with easy player transfer between servers
• Supports plugin development for extended functionality
• Provides efficient player management and load balancing
• Offers enhanced security features like IP forwarding and firewall capabilities

Cons

• Can introduce additional latency due to the proxy layer
• Requires more complex setup compared to standalone Minecraft servers
• May have compatibility issues with some Minecraft mods or plugins
• Performance can be impacted when handling a large number of players

Code Examples

// Example 1: Creating a simple BungeeCord plugin
public class MyPlugin extends Plugin {
    @Override
    public void onEnable() {
        getLogger().info("MyPlugin has been enabled!");
    }

    @Override
    public void onDisable() {
        getLogger().info("MyPlugin has been disabled!");
    }
}

// Example 2: Listening for player join events
@EventHandler
public void onPlayerJoin(PostLoginEvent event) {
    ProxiedPlayer player = event.getPlayer();
    player.sendMessage(new TextComponent("Welcome to the network!"));
}

// Example 3: Sending a player to another server
public void sendPlayerToServer(ProxiedPlayer player, String serverName) {
    ServerInfo targetServer = ProxyServer.getInstance().getServerInfo(serverName);
    if (targetServer != null) {
        player.connect(targetServer);
    }
}

Getting Started

1. Download the latest BungeeCord.jar from the official website.
2. Create a start script (e.g., start.bat or start.sh) with the following content:

   java -jar BungeeCord.jar
   

3. Run the start script to generate configuration files.
4. Edit config.yml to add your Minecraft servers:

   servers:
     lobby:
       motd: 'Welcome to the Lobby'
       address: localhost:25565
     minigames:
       motd: 'Minigames Server'
       address: localhost:25566
   

5. Configure your Minecraft servers to work with BungeeCord by setting online-mode=false in server.properties.
6. Restart BungeeCord and your Minecraft servers.
