go-raknet

go-raknet is a library that implements a basic version of the RakNet protocol, which is used for Minecraft (Bedrock Edition). It implements Unreliable, Reliable and ReliableOrdered packets and sends user packets as ReliableOrdered.

go-raknet attempts to abstract away direct interaction with RakNet, and provides simple to use, idiomatic Go API used to listen for connections or connect to servers.

Getting started

Prerequisites

As of go-raknet version 1.14.0, go-raknet requires at least Go 1.22. Version 1.12.1 of go-raknet is the last version of the library that supports Go 1.18 and above.

Usage

go-raknet can be used for both clients and servers, (and proxies, when combined) in a way very similar to the standard net.TCP* functions.

Basic RakNet server:

package main

import (
    "github.com/sandertv/go-raknet"
)

func main() {
    listener, _ := raknet.Listen("0.0.0.0:19132")
    defer listener.Close()
    for {
        conn, _ := listener.Accept()

        b := make([]byte, 1024*1024*4)
        _, _ = conn.Read(b)
        _, _ = conn.Write([]byte{1, 2, 3})

        conn.Close()
    }
}

Basic RakNet client:

package main

import (
    "github.com/sandertv/go-raknet"
)

func main() {
    conn, _ := raknet.Dial("mco.mineplex.com:19132")
    defer conn.Close()

    b := make([]byte, 1024*1024*4)
    _, _ = conn.Write([]byte{1, 2, 3})
    _, _ = conn.Read(b)
}
