Description
-----------

Base class for WebSocket server and client, allowing them to be used as multiplayer peer for the :ref:`MultiplayerAPI<class_MultiplayerAPI>`.

\ **Note:** When exporting to Android, make sure to enable the ``INTERNET`` 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.

Method Descriptions
-------------------

.. _class_WebSocketMultiplayerPeer_method_create_client:

.. rst-class:: classref-method

:ref:`Error<enum_@GlobalScope_Error>` **create_client** **(** :ref:`String<class_String>` url, :ref:`TLSOptions<class_TLSOptions>` tls_client_options=null **)**

Starts a new multiplayer client connecting to the given ``url``. TLS certificates will be verified against the hostname when connecting using the ``wss://`` protocol. You can pass the optional ``tls_client_options`` parameter to customize the trusted certification authorities, or disable the common name verification. See :ref:`TLSOptions.client<class_TLSOptions_method_client>` and :ref:`TLSOptions.client_unsafe<class_TLSOptions_method_client_unsafe>`.

\ **Note:** It is recommended to specify the scheme part of the URL, i.e. the ``url`` should start with either ``ws://`` or ``wss://``.

Starts a new multiplayer server listening on the given ``port``. You can optionally specify a ``bind_address``, and provide valid ``tls_server_options`` to use TLS. See :ref:`TLSOptions.server<class_TLSOptions_method_server>`.

.. rst-class:: classref-item-separator
