A WebSocket client implementation This class implements a WebSocket client compatible with any RFC 6455 complaint WebSocket server. This client can be optionally used as a network peer for the [MultiplayerAPI]. After starting the client ([method connect_to_url]), you will need to [method NetworkedMultiplayerPeer.poll] it at regular intervals (e.g. inside [method Node._process]). You will received appropriate signals when connecting, disconnecting, or when new data is available. Connect to the given URL requesting one of the given [code]protocols[/code] as sub-protocol. If [code]true[/code] is passed as [code]gd_mp_api[/code], the client will behave like a network peer for the [MultiplayerAPI]. Note: connections to non Godot servers will not work, and [signal data_received] will not be emitted when this option is true. Disconnect this client from the connected host. See [method WebSocketPeer.close] for more info. Enable or disable SSL certificate verification. Note: You must specify the certificates to be used in the project settings for it to work when exported. Emitted when the connection to the server is closed. [code]was_clean_close[/code] will be [code]true[/code] if the connection was shutdown cleanly. Emitted when the connection to the server fails. Emitted when a connection with the server is established, [code]protocol[/code] will contain the sub-protocol agreed with the server. Emitted when a WebSocket message is received. Note: This signal is NOT emitted when used as high level multiplayer peer. Emitted when the server requests a clean close. You should keep polling until you get a [signal connection_closed] signal to achieve the clean close. See [method WebSocketPeer.close] for more details.
