Property Descriptions

PackedStringArray handshake_headers = PackedStringArray() 🔗

The extra headers to use during handshake. See WebSocketPeer.handshake_headers for more details.

Note: The returned array is copied and any changes to it will not update the original property value. See PackedStringArray for more details.

float handshake_timeout = 3.0 🔗

  • void set_handshake_timeout(value: float)

  • float get_handshake_timeout()

The maximum time each peer can stay in a connecting state before being dropped.

int inbound_buffer_size = 65535 🔗

  • void set_inbound_buffer_size(value: int)

  • int get_inbound_buffer_size()

The inbound buffer size for connected peers. See WebSocketPeer.inbound_buffer_size for more details.

int max_queued_packets = 2048 🔗

  • void set_max_queued_packets(value: int)

  • int get_max_queued_packets()

The maximum number of queued packets for connected peers. See WebSocketPeer.max_queued_packets for more details.

int outbound_buffer_size = 65535 🔗

  • void set_outbound_buffer_size(value: int)

  • int get_outbound_buffer_size()

The outbound buffer size for connected peers. See WebSocketPeer.outbound_buffer_size for more details.

PackedStringArray supported_protocols = PackedStringArray() 🔗

The supported WebSocket sub-protocols. See WebSocketPeer.supported_protocols for more details.

Note: The returned array is copied and any changes to it will not update the original property value. See PackedStringArray for more details.

Method Descriptions

Error create_client(url: String, tls_client_options: TLSOptions = 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 TLSOptions.client and TLSOptions.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://.

Error create_server(port: int, bind_address: String = “*“, tls_server_options: TLSOptions = null) 🔗

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 TLSOptions.server.

WebSocketPeer get_peer(peer_id: int) const 🔗

Returns the WebSocketPeer associated to the given peer_id.

String get_peer_address(id: int) const 🔗

Returns the IP address of the given peer.

int get_peer_port(id: int) const 🔗

Returns the remote port of the given peer.
