<description>
Set the state of the connection. See [enum NetworkedMultiplayerPeer.ConnectionStatus].
This will emit the [signal NetworkedMultiplayerPeer.connection_succeeded], [signal NetworkedMultiplayerPeer.connection_failed] or [signal NetworkedMultiplayerPeer.server_disconnected] signals depending on the status and if the peer has the unique network id of [code]1[/code].
You can only change to [code]CONNECTION_CONNECTING[/code] from [code]CONNECTION_DISCONNECTED[/code] and to [code]CONNECTION_CONNECTED[/code] from [code]CONNECTION_CONNECTING[/code].
