Events can then be handled by connecting to [SceneTree] signals. - ENet's purpose is to provide a relatively thin, simple and robust network communication layer on top of UDP (User Datagram Protocol). - [b]Note:[/b] ENet only uses UDP, not TCP. When forwarding the server port to make your server accessible on the public Internet, you only need to forward the server port in UDP. You can use the [UPNP] class to try to forward the server port automatically when starting the server. - </description> - <tutorials> - <link title="High-level multiplayer">https://docs.godotengine.org/en/latest/tutorials/networking/high_level_multiplayer.html</link> - <link title="API documentation on the ENet website">http://enet.bespin.org/usergroup0.html</link> - </tutorials> - <methods> - <method name="close_connection"> - <return type="void"> - </return> - <argument index="0" name="wait_usec" type="int" default="100"> - </argument> - <description> - Closes the connection.

The given address needs to be either a fully qualified domain name (e.g. [code]"www.example.com"[/code]) or an IP address in IPv4 or IPv6 format (e.g. [code]"192.168.1.1"[/code]). The [code]port[/code] is the port the server is listening on. The [code]in_bandwidth[/code] and [code]out_bandwidth[/code] parameters can be used to limit the incoming and outgoing bandwidth to the given number of bytes per second. The default of 0 means unlimited bandwidth. Note that ENet will strategically drop packets on specific sides of a connection between peers to ensure the peer's bandwidth is not overwhelmed. The bandwidth parameters also determine the window size of a connection which limits the amount of reliable packets that may be in transit at any given time. Returns [constant OK] if a client was created, [constant ERR_ALREADY_IN_USE] if this NetworkedMultiplayerENet instance already has an open connection (in which case you need to call [method close_connection] first) or [constant ERR_CANT_CREATE] if the client could not be created. If [code]local_port[/code] is specified, the client will also listen to the given port; this is useful for some NAT traversal techniques. - </description> - </method> - <method name="create_server"> - <return type="int" enum="Error"> - </return> - <argument index="0" name="port" type="int"> - </argument> - <argument index="1" name="max_clients" type="int" default="32"> - </argument> - <argument index="2" name="in_bandwidth" type="int" default="0"> - </argument> - <argument index="3" name="out_bandwidth" type="int" default="0"> - </argument> - <description> - Create server that listens to connections via [code]port[/code]. The port needs to be an available, unused port between 0 and 65535. Note that ports below 1024 are privileged and may require elevated permissions depending on the platform.

[code]max_clients[/code] is the maximum number of clients that are allowed at once, any number up to 4095 may be used, although the achievable number of simultaneous clients may be far lower and depends on the application.

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 [code]timeout_limit[/code] 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 [code]timeout_min[/code].
