Udp

To send or receive messages via UDP use the socket python library.

Add the following script to PolyVR and trigger it with a timeout each 50 ms.

import socket, VR

if not hasattr(VR, 'udpsock'):
	VR.udpsock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM) # internet, UDP
	VR.udpsock.bind( ('localhost', 6060) )
	VR.udpsock.setblocking(0)

try:
	data, addr = VR.udpsock.recvfrom(10)
	print "received message:", float(data)
except:
	pass

Add another script to your PolyVR project to configure your socket on demand:

import socket, VR
VR.udpsock.close()
VR.udpsock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM) # internet, UDP
VR.udpsock.setblocking(0)
VR.udpsock.bind( ('localhost', 6060) )

Test it with the following python script:

import socket
msg = "Hello, World!"
sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
sock.sendto(msg, ('141.3.150.20', 6060))
