Inherits: NetworkedMultiplayerPeer < PacketPeer < Reference < Object

A simple interface to create a peer-to-peer mesh network composed of WebRTCPeerConnection that is compatible with the MultiplayerAPI.


This class constructs a full mesh of WebRTCPeerConnection (one connection for each peer) that can be used as a MultiplayerAPI.network_peer.

You can add each WebRTCPeerConnection via add_peer or remove them via remove_peer. Peers must be added in WebRTCPeerConnection.STATE_NEW state to allow it to create the appropriate channels. This class will not create offers nor set descriptions, it will only poll them, and notify connections and disconnections.

NetworkedMultiplayerPeer.connection_succeeded and NetworkedMultiplayerPeer.server_disconnected will not be emitted unless server_compatibility is true in initialize. Beside that data transfer works like in a NetworkedMultiplayerPeer.

Method Descriptions

Add a new peer to the mesh with the given peer_id. The WebRTCPeerConnection must be in state WebRTCPeerConnection.STATE_NEW.

Three channels will be created for reliable, unreliable, and ordered transport. The value of unreliable_lifetime will be passed to the maxPacketLifetime option when creating unreliable and ordered channels (see WebRTCPeerConnection.create_data_channel).

  • void close ( )

Close all the add peer connections and channels, freeing all resources.

Return a dictionary representation of the peer with given peer_id with three keys. connection containing the WebRTCPeerConnection to this peer, channels an array of three WebRTCDataChannel, and connected a boolean representing if the peer connection is currently connected (all three channels are open).

Returns a dictionary which keys are the peer ids and values the peer representation as in get_peer.

Returns true if the given peer_id is in the peers map (it might not be connected though).

  • Error initialize ( int peer_id, bool server_compatibility=false )

Initialize the multiplayer peer with the given peer_id (must be between 1 and 2147483647).

If server_compatibilty is false (default), the multiplayer peer will be immediately in state NetworkedMultiplayerPeer.CONNECTION_CONNECTED and NetworkedMultiplayerPeer.connection_succeeded will not be emitted.

If server_compatibilty is true the peer will suppress all NetworkedMultiplayerPeer.peer_connected signals until a peer with id NetworkedMultiplayerPeer.TARGET_PEER_SERVER connects and then emit NetworkedMultiplayerPeer.connection_succeeded. After that the signal NetworkedMultiplayerPeer.peer_connected will be emitted for every already connected peer, and any new peer that might connect. If the server peer disconnects after that, signal NetworkedMultiplayerPeer.server_disconnected will be emitted and state will become NetworkedMultiplayerPeer.CONNECTION_CONNECTED.

  • void remove_peer ( int peer_id )

Remove the peer with given peer_id from the mesh. If the peer was connected, and NetworkedMultiplayerPeer.peer_connected was emitted for it, then NetworkedMultiplayerPeer.peer_disconnected will be emitted.
