<?xml version="1.0" encoding="UTF-8" ?> <class name="WebRTCMultiplayer" inherits="NetworkedMultiplayerPeer" version="3.5" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="../../../doc/class.xsd"> <brief_description> A simple interface to create a peer-to-peer mesh network composed of [WebRTCPeerConnection] that is compatible with the [MultiplayerAPI]. </brief_description> <description> This class constructs a full mesh of [WebRTCPeerConnection] (one connection for each peer) that can be used as a [member MultiplayerAPI.network_peer]. You can add each [WebRTCPeerConnection] via [method add_peer] or remove them via [method remove_peer]. Peers must be added in [constant 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. [signal NetworkedMultiplayerPeer.connection_succeeded] and [signal NetworkedMultiplayerPeer.server_disconnected] will not be emitted unless [code]server_compatibility[/code] is [code]true[/code] in [method initialize]. Beside that data transfer works like in a [NetworkedMultiplayerPeer]. </description> <tutorials> </tutorials> <methods> <method name="add_peer"> <return type="int" enum="Error" /> <argument index="0" name="peer" type="WebRTCPeerConnection" /> <argument index="1" name="peer_id" type="int" /> <argument index="2" name="unreliable_lifetime" type="int" default="1" /> <description> Add a new peer to the mesh with the given [code]peer_id[/code]. The [WebRTCPeerConnection] must be in state [constant WebRTCPeerConnection.STATE_NEW]. Three channels will be created for reliable, unreliable, and ordered transport. The value of [code]unreliable_lifetime[/code] will be passed to the [code]maxPacketLifetime[/code] option when creating unreliable and ordered channels (see [method WebRTCPeerConnection.create_data_channel]). </description> </method> <method name="close"> <return type="void" /> <description> Close all the add peer connections and channels, freeing all resources. </description> </method> <method name="get_peer"> <return type="Dictionary" /> <argument index="0" name="peer_id" type="int" /> <description> Return a dictionary representation of the peer with given [code]peer_id[/code] with three keys. [code]connection[/code] containing the [WebRTCPeerConnection] to this peer, [code]channels[/code] an array of three [WebRTCDataChannel], and [code]connected[/code] a boolean representing if the peer connection is currently connected (all three channels are open). </description> </method> <method name="get_peers"> <return type="Dictionary" /> <description> Returns a dictionary which keys are the peer ids and values the peer representation as in [method get_peer]. </description> </method> <method name="has_peer"> <return type="bool" /> <argument index="0" name="peer_id" type="int" /> <description> Returns [code]true[/code] if the given [code]peer_id[/code] is in the peers map (it might not be connected though). </description> </method> <method name="initialize"> <return type="int" enum="Error" /> <argument index="0" name="peer_id" type="int" /> <argument index="1" name="server_compatibility" type="bool" default="false" /> <description> Initialize the multiplayer peer with the given [code]peer_id[/code] (must be between 1 and 2147483647). If [code]server_compatibilty[/code] is [code]false[/code] (default), the multiplayer peer will be immediately in state [constant NetworkedMultiplayerPeer.CONNECTION_CONNECTED] and [signal NetworkedMultiplayerPeer.connection_succeeded] will not be emitted. If [code]server_compatibilty[/code] is [code]true[/code] the peer will suppress all [signal NetworkedMultiplayerPeer.peer_connected] signals until a peer with id [constant NetworkedMultiplayerPeer.TARGET_PEER_SERVER] connects and then emit [signal NetworkedMultiplayerPeer.connection_succeeded]. After that the signal [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 [signal NetworkedMultiplayerPeer.server_disconnected] will be emitted and state will become [constant NetworkedMultiplayerPeer.CONNECTION_CONNECTED]. </description> </method> <method name="remove_peer"> <return type="void" /> <argument index="0" name="peer_id" type="int" /> <description> Remove the peer with given [code]peer_id[/code] from the mesh. If the peer was connected, and [signal NetworkedMultiplayerPeer.peer_connected] was emitted for it, then [signal NetworkedMultiplayerPeer.peer_disconnected] will be emitted. </description> </method> </methods> <constants> </constants> </class>
