Hi there,
I’m trying to see what sending an image to a PacketPeerUDP looks like in godot. I have a server which captures a Camera’s view of a scene as a PoolByteArray and then attempts to put that data to a client PacketPeerUDP but I don’t usually see the client respond even with simple length of received byte checks.
Server Node
extends Node
var server := UDPServer.new()
var peers = []
func _ready():
server.listen(4242)
var step = 0
func _process(delta):
server.poll() # Important!
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)
step +=1
if step %100==0:
step =0
for i in range(0, peers.size()):
var peer = peers[i]
if peer.get_available_packet_count()>0:
print("peer alive")
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.
var im_data = get_viewport().get_texture().get_data().get_data()
print(len(im_data))
var cursor = 0
var step = 20
while cursor < len(im_data):
peer.put_packet(im_data.subarray(cursor,cursor+step))
cursor +=step
pass # Do something with the connected peers.
Client Node
# 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 udp.get_available_packet_count() > 0:
print("message back")
print("num packets",udp.get_available_packet_count())
print(len(udp.get_packet()))
connected = true
func _on_Button_button_down():
udp.put_packet("The answer is... 42!".to_utf8())
pass # Replace with function body.
