Helper class to implement a UDP server. A simple server that opens a UDP socket and returns connected [PacketPeerUDP] upon receiving new packets. See also [method PacketPeerUDP.connect_to_host]. Below a small example of how it can be used: [codeblock] # server.gd extends Node var server := UDPServer.new() var peers = [] func _ready(): server.listen(4242) func _process(delta): if server.is_connection_available(): var peer : PacketPeerUDP = server.take_connection() var pkt = peer.get_packet() print("Accepted peer: %s:%s" % [peer.get_packet_ip(), peer.get_packet_port()]) print("Received data: %s" % [pkt.get_string_from_utf8()]) # Reply so it knows we received the message. peer.put_packet(pkt) # Keep a reference so we can keep contacting the remote peer. peers.append(peer) for i in range(0, peers.size()): pass # Do something with the connected peers. [/codeblock] [codeblock] # client.gd extends Node var udp := PacketPeerUDP.new() var connected = false func _ready(): udp.connect_to_host("127.0.0.1", 4242) func _process(delta): if !connected: # Try to contact server udp.put_packet("The answer is... 42!".to_utf8()) if udp.get_available_packet_count() > 0: print("Connected: %s" % udp.get_packet().get_string_from_utf8()) connected = true [/codeblock] Returns [code]true[/code] if a packet with a new address/port combination is received on the socket. Returns [code]true[/code] if the socket is open and listening on a port. Starts the server by opening a UDP socket listening on the given port. You can optionally specify a [code]bind_address[/code] to only listen for packets sent to that address. See also [method PacketPeerUDP.listen]. Stops the server, closing the UDP socket if open. Will not disconnect any connected [PacketPeerUDP]. Returns a [PacketPeerUDP] connected to the address/port combination of the first packet in queue. Will return [code]null[/code] if no packet is in queue. See also [method PacketPeerUDP.connect_to_host].
