You probably don't want to loop like that for a number of reasons,
1. You could miss the turn change.
2. It's unreliable.
3. It's consuming extra resources.
The servers will send you an asyncronous frame when turn generation
occurs (or when the turn length changes). On the java library I have no
idea how to find this frame, but in Python you do something like this,
while <condition>:
self.connection.pump()
pending = self.connection.buffered['frames-async']
while len(pending) > 0:
if not isinstance(pending[0], tpobjects.TimeRemaining):
break
frame = pending.pop(0)
if frame.time == 0:
# Turn generation just occurred..
else:
# EOT time changed...
# You only need the sleep if you are in non-blocking mode
time.sleep(1)
Hope that helps.
