ENetPacketPeer
==============

**Inherits:** :ref:`PacketPeer<class_PacketPeer>` **<** :ref:`RefCounted<class_RefCounted>` **<** :ref:`Object<class_Object>`

A wrapper class for an `ENetPeer <http://enet.bespin.org/group__peer.html>`__.

.. rst-class:: classref-introduction-group

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

A PacketPeer implementation representing a peer of an :ref:`ENetConnection<class_ENetConnection>`.

This class cannot be instantiated directly but can be retrieved during :ref:`ENetConnection.service<class_ENetConnection_method_service>` or via :ref:`ENetConnection.get_peers<class_ENetConnection_method_get_peers>`.

\ **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.

|void| **peer_disconnect**\ (\ data\: :ref:`int<class_int>` = 0\ ) :ref:`🔗<class_ENetPacketPeer_method_peer_disconnect>`

Request a disconnection from a peer. An :ref:`ENetConnection.EVENT_DISCONNECT<class_ENetConnection_constant_EVENT_DISCONNECT>` will be generated during :ref:`ENetConnection.service<class_ENetConnection_method_service>` once the disconnection is complete.

Sets the timeout parameters for a peer. The timeout parameters control how and when a peer will timeout from a failure to acknowledge reliable traffic. Timeout values are expressed in milliseconds.

The ``timeout`` is a factor that, multiplied by a value based on the average round trip time, will determine the timeout limit for a reliable packet. When that limit is reached, the timeout will be doubled, and the peer will be disconnected if that limit has reached ``timeout_min``. The ``timeout_max`` parameter, on the other hand, defines a fixed timeout for which any packet must be acknowledged or the peer will be dropped.

|void| **throttle_configure**\ (\ interval\: :ref:`int<class_int>`, acceleration\: :ref:`int<class_int>`, deceleration\: :ref:`int<class_int>`\ ) :ref:`🔗<class_ENetPacketPeer_method_throttle_configure>`

Configures throttle parameter for a peer.

Unreliable packets are dropped by ENet in response to the varying conditions of the Internet connection to the peer. The throttle represents a probability that an unreliable packet should not be dropped and thus sent by ENet to the peer. By measuring fluctuations in round trip times of reliable packets over the specified ``interval``, ENet will either increase the probability by the amount specified in the ``acceleration`` parameter, or decrease it by the amount specified in the ``deceleration`` parameter (both are ratios to :ref:`PACKET_THROTTLE_SCALE<class_ENetPacketPeer_constant_PACKET_THROTTLE_SCALE>`).

When the throttle has a value of :ref:`PACKET_THROTTLE_SCALE<class_ENetPacketPeer_constant_PACKET_THROTTLE_SCALE>`, no unreliable packets are dropped by ENet, and so 100% of all unreliable packets will be sent.

When the throttle has a value of ``0``, all unreliable packets are dropped by ENet, and so 0% of all unreliable packets will be sent.

Intermediate values for the throttle represent intermediate probabilities between 0% and 100% of unreliable packets being sent. The bandwidth limits of the local and foreign hosts are taken into account to determine a sensible limit for the throttle probability above which it should not raise even in the best of conditions.
