  • To avoid having players have to port forward to play with friends

Plugins

Optional - Highly recommend since this is the only working Networking layer currently

• Steam
  • https://github.com/CoaguCo-Industries/GodotSteam

• P2PLobby

Example

• GodotP2PNetworkExample

RPC Signal

P2PNetwork.rpc_emit_signal(object,"SingalName")
P2PNetwork.rpc_emit_signal(object,"SingalName",[args])

Example

P2PNetwork.rpc_emit_signal(SignalBus,"Explosion",[damage,damage_type])

RPC Method

func _ready():
    P2PNetwork.network_access.register_method(Callable)
    P2PNetwork.rpc_method(Callable)

func _ready():
    P2PNetwork.network_access.register_method(send_message)
    P2PNetwork.rpc_method(send_message.bind("Hello!"))

func send_message(msg:String):
    print(msg)

RPC Sync

extends Node

@export var sync_priority:P2PNetwork.SYNC_PRIORITY = P2PNetwork.SYNC_PRIORITY.LOW
var network_id:int
var _recieved:bool

func _ready():
    NetworkNodeHelper.set_object_name(self)
    P2PLobby.player_left_lobby.connect(player_left)
    P2PLobby.player_joined_lobby.connect(player_joined)
    P2PNetwork.globalData.player_data_updated.connect(_player_data_updated)
    P2PNetwork.disconnect.connect(destroy)
    P2PNetwork.periodic_sync.connect(_periodic_sync_timeout)

func _recived_obj(network_id,path):
    if _recieved:
        return
    if path == get_path():
        _recieved = true

RPC Queue Free

Deletes the provided object for all connected clients. You will have to be a server or object owner to call.

    P2PNetwork.rpc_remove_node(self)

Global Data

P2PNetwork.globalData.set_game_data("key",value)

Example

P2PNetwork.globalData.set_game_data("map_seed",map_seed)
var map_seed = P2PNetwork.globalData.get_game_data("map_seed")
