PodSixNet is a lightweight network layer designed to make it easy to write multiplayer games in Python. It uses Python's built in asyncore library and rencode.py (included) to asynchronously serialize network events and arbitrary data structures, and delivers them to your high level classes through simple callback methods. Each class within your game client that wants to receive network events subclasses the ConnectionListener class and then implements Network_* methods to catch specific user-defined events from the server. You don't have to wait for buffers to fill, check sockets for waiting data, etc. Just do connection.Pump() once per game loop and the library will handle everything else for you, passing off events to all classes that are listening. Sending data back to the server is just as easy by using connection.Send(mydata). Likewise on the server side, events are propagated to Network_* method callbacks and data is sent back to clients with the client.Send(mydata) method.
Cheese tracker is developing into a great and very usable tracker. In my opinion the area in which Linux trackers such as soundtracker are currently falling behind is that of effects. Cheese tracker is making leaps and bounds in this area and that reason alone puts it in a better class. Perhaps Juan would consider implenting some kind of standard effects architecture so users can write their own effects?
