	<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.multiplayer_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 MultiplayerPeer.connection_succeeded] and [signal MultiplayerPeer.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 [MultiplayerPeer].
		[b]Note:[/b] When exporting to Android, make sure to enable the [code]INTERNET[/code] permission in the Android export preset before exporting the project or using one-click deploy. Otherwise, network communication of any kind will be blocked by Android.

	<methods>
		<method name="add_peer">
			<return type="int" enum="Error" />
			<param index="0" name="peer" type="WebRTCPeerConnection" />
			<param index="1" name="peer_id" type="int" />
			<param 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" />
			<param index="0" name="peer_id" type="int" />
			<description>
				Returns 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" />
			<param 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" />
			<param index="0" name="peer_id" type="int" />
			<param index="1" name="server_compatibility" type="bool" default="false" />
			<param index="2" name="channels_config" type="Array" default="[]" />
			<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 MultiplayerPeer.CONNECTION_CONNECTED] and [signal MultiplayerPeer.connection_succeeded] will not be emitted.
				If [code]server_compatibilty[/code] is [code]true[/code] the peer will suppress all [signal MultiplayerPeer.peer_connected] signals until a peer with id [constant MultiplayerPeer.TARGET_PEER_SERVER] connects and then emit [signal MultiplayerPeer.connection_succeeded]. After that the signal [signal MultiplayerPeer.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 MultiplayerPeer.server_disconnected] will be emitted and state will become [constant MultiplayerPeer.CONNECTION_CONNECTED].
				You can optionally specify a [code]channels_config[/code] array of [enum MultiplayerPeer.TransferMode] which will be used to create extra channels (WebRTC only supports one transfer mode per channel).
			</description>
		</method>
		<method name="remove_peer">
			<return type="void" />
			<param 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 MultiplayerPeer.peer_connected] was emitted for it, then [signal MultiplayerPeer.peer_disconnected] will be emitted.
