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.
To use this library, Go must be installed. go-raknet does not depend on any other libraries than the standard Go library.
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/raknet"
)
func main() {
// We start a listener with in this case a specific protocol.
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/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)
}For an example on how to apply these and other methods in order to create a proxy, see the examples/proxy folder.
