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.
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.
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)
}
