Helper class to implement a UDP server.
After starting the server (listen), you will need to poll it at regular intervals (e.g. inside Node._process) for it to process new packets, delivering them to the appropriate PacketPeerUDP, and taking new connections.
Below a small example of how it can be used:
# server_node.gd class_name ServerNode extends Node var server := UDPServer.new() var peers =  func _ready(): server.listen(4242) func _process(delta): server.poll() # Important! if server.is_connection_available(): var peer: PacketPeerUDP = server.take_connection() var packet = peer.get_packet() print("Accepted peer: %s:%s" % [peer.get_packet_ip(), peer.get_packet_port()]) print("Received data: %s" % [packet.get_string_from_utf8()]) # Reply so it knows we received the message. peer.put_packet(packet) # 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.
