- Description
- -----------
- UDP packet peer. Can be used to send raw UDP packets as well as :ref:`Variant<class_Variant>`\ s.
- Method Descriptions
- -------------------
- .. _class_PacketPeerUDP_method_close:
- - void **close** **(** **)**
- Closes the UDP socket the ``PacketPeerUDP`` is currently listening on.
- .. _class_PacketPeerUDP_method_get_packet_ip:
- - :ref:`String<class_String>` **get_packet_ip** **(** **)** const
- Returns the IP of the remote peer that sent the last packet(that was received with :ref:`PacketPeer.get_packet<class_PacketPeer_method_get_packet>` or :ref:`PacketPeer.get_var<class_PacketPeer_method_get_var>`).
- .. _class_PacketPeerUDP_method_get_packet_port:
- - :ref:`int<class_int>` **get_packet_port** **(** **)** const
- Returns the port of the remote peer that sent the last packet(that was received with :ref:`PacketPeer.get_packet<class_PacketPeer_method_get_packet>` or :ref:`PacketPeer.get_var<class_PacketPeer_method_get_var>`).
- .. _class_PacketPeerUDP_method_is_listening:
- - :ref:`bool<class_bool>` **is_listening** **(** **)** const
- Returns whether this ``PacketPeerUDP`` is listening.
- .. _class_PacketPeerUDP_method_join_multicast_group:
- - :ref:`Error<enum_@GlobalScope_Error>` **join_multicast_group** **(** :ref:`String<class_String>` multicast_address, :ref:`String<class_String>` interface_name **)**
- Joins the multicast group specified by ``multicast_address`` using the interface identified by ``interface_name``.
- You can join the same multicast group with multiple interfaces. Use :ref:`IP.get_local_interfaces<class_IP_method_get_local_interfaces>` to know which are available.
- .. _class_PacketPeerUDP_method_leave_multicast_group:
- - :ref:`Error<enum_@GlobalScope_Error>` **leave_multicast_group** **(** :ref:`String<class_String>` multicast_address, :ref:`String<class_String>` interface_name **)**
- Removes the interface identified by ``interface_name`` from the multicast group specified by ``multicast_address``.
- .. _class_PacketPeerUDP_method_listen:
- - :ref:`Error<enum_@GlobalScope_Error>` **listen** **(** :ref:`int<class_int>` port, :ref:`String<class_String>` bind_address="*", :ref:`int<class_int>` recv_buf_size=65536 **)**
- Makes this ``PacketPeerUDP`` listen on the ``port`` binding to ``bind_address`` with a buffer size ``recv_buf_size``.
- If ``bind_address`` is set to ``"*"`` (default), the peer will listen on all available addresses (both IPv4 and IPv6).
- If ``bind_address`` is set to ``"0.0.0.0"`` (for IPv4) or ``"::"`` (for IPv6), the peer will listen on all available addresses matching that IP type.
- If ``bind_address`` is set to any valid address (e.g. ``"192.168.1.101"``, ``"::1"``, etc), the peer will only listen on the interface with that addresses (or fail if no interface with the given address exists).
- .. _class_PacketPeerUDP_method_set_dest_address:
- - :ref:`Error<enum_@GlobalScope_Error>` **set_dest_address** **(** :ref:`String<class_String>` host, :ref:`int<class_int>` port **)**
- Sets the destination address and port for sending packets and variables. A hostname will be resolved using DNS if needed.
- .. _class_PacketPeerUDP_method_wait:
- - :ref:`Error<enum_@GlobalScope_Error>` **wait** **(** **)**
- Waits for a packet to arrive on the listening port. See :ref:`listen<class_PacketPeerUDP_method_listen>`.
