godot-matcha

Easy webrtc matchmaking using WebTorrent tracker.
This project uses webtorrent to do signaling. This allows you to connect players peer2peer without a server!
I plan on improving this library and add more features. Stay tuned!

Installation

  1. Copy addons/matcha to your godot project.
  2. For non browser builds: Install webrtc-native
  3. Done!

Usage

Example (Mesh):

extends Node

var mp1 := MatchaRoom.create_mesh_room({ "identifier": "my-unique-game-identifier" })
var mp2 := MatchaRoom.create_mesh_room({ "identifier": "my-unique-game-identifier" })

func _init():
	mp1.peer_joined.connect(func(_id, peer):
		print("(1) Peer connected: ", peer.peer_id)
	)

	mp1.peer_left.connect(func(_id, peer):
		print("(1) Peer disconnected: ", peer.peer_id)
	)

	mp2.peer_joined.connect(func(_id, peer):
		print("(2) Peer connected: ", peer.peer_id)
	)

	mp2.peer_left.connect(func(_id, peer):
		print("(2) Peer disconnected: ", peer.peer_id)
	)

Example (Server/Client):

extends Node

var server := MatchaRoom.create_server_room()
var client := MatchaRoom.create_client_room(server.room_id) # Client must know the room id

func _init():
	server.peer_joined.connect(func(_id, peer):
		print("(server) Peer connected: ", peer.peer_id)
	)

	server.peer_left.connect(func(_id, peer):
		print("(server) Peer disconnected: ", peer.peer_id)
	)

	client.peer_joined.connect(func(_id, peer):
		print("(client) Peer connected: ", peer.peer_id)
	)

	client.peer_left.connect(func(_id, peer):
		print("(client) Peer disconnected: ", peer.peer_id)
	)

Big thanks :)
