  36. Method Descriptions
  37. -------------------
  38. .. _class_PacketPeerUDP_method_close:
  39. - void **close** **(** **)**
  40. Closes the UDP socket the ``PacketPeerUDP`` is currently listening on.
  41. ----
  42. .. _class_PacketPeerUDP_method_get_packet_ip:
  43. - :ref:`String<class_String>` **get_packet_ip** **(** **)** const
  44. 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>`).
  45. ----
  46. .. _class_PacketPeerUDP_method_get_packet_port:
  47. - :ref:`int<class_int>` **get_packet_port** **(** **)** const
  48. 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>`).
  49. ----
  50. .. _class_PacketPeerUDP_method_is_listening:
  51. - :ref:`bool<class_bool>` **is_listening** **(** **)** const
  52. Returns whether this ``PacketPeerUDP`` is listening.
  53. ----
  54. .. _class_PacketPeerUDP_method_join_multicast_group:
  55. - :ref:`Error<enum_@GlobalScope_Error>` **join_multicast_group** **(** :ref:`String<class_String>` multicast_address, :ref:`String<class_String>` interface_name **)**
  56. Joins the multicast group specified by ``multicast_address`` using the interface identified by ``interface_name``.
  57. 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.
  58. Note: Some Android devices might require the ``CHANGE_WIFI_MULTICAST_STATE`` permission for multicast to work.
  59. ----
  60. .. _class_PacketPeerUDP_method_leave_multicast_group:
  61. - :ref:`Error<enum_@GlobalScope_Error>` **leave_multicast_group** **(** :ref:`String<class_String>` multicast_address, :ref:`String<class_String>` interface_name **)**
  62. Removes the interface identified by ``interface_name`` from the multicast group specified by ``multicast_address``.
  63. ----
  64. .. _class_PacketPeerUDP_method_listen:
  65. - :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 **)**
  66. Makes this ``PacketPeerUDP`` listen on the ``port`` binding to ``bind_address`` with a buffer size ``recv_buf_size``.
  67. If ``bind_address`` is set to ``"*"`` (default), the peer will listen on all available addresses (both IPv4 and IPv6).
  68. 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.
  69. 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).
  70. ----
  71. .. _class_PacketPeerUDP_method_set_broadcast_enabled:
  72. - void **set_broadcast_enabled** **(** :ref:`bool<class_bool>` enabled **)**
  73. Enable or disable sending of broadcast packets (e.g. ``set_dest_address("255.255.255.255", 4343)``. This option is disabled by default.
  74. Note: Some Android devices might require the ``CHANGE_WIFI_MULTICAST_STATE`` permission and this option to be enabled to receive broadcast packets too.
  75. ----
  76. .. _class_PacketPeerUDP_method_set_dest_address:
  77. - :ref:`Error<enum_@GlobalScope_Error>` **set_dest_address** **(** :ref:`String<class_String>` host, :ref:`int<class_int>` port **)**
  78. Sets the destination address and port for sending packets and variables. A hostname will be resolved using DNS if needed.
  79. Note: :ref:`set_broadcast_enabled<class_PacketPeerUDP_method_set_broadcast_enabled>` must be enabled before sending packets to a broadcast address (e.g. ``255.255.255.255``).
  80. ----
  81. .. _class_PacketPeerUDP_method_wait:
  82. - :ref:`Error<enum_@GlobalScope_Error>` **wait** **(** **)**
  83. Waits for a packet to arrive on the listening port. See :ref:`listen<class_PacketPeerUDP_method_listen>`.
