| Ok, I do not have the time to analyze that code. If you dont mind some positive criticism allow me to make a few suggestions. First off Indent your code. It will be impossible for you and everyone else to easily decipher exactly what the heck is going on. Secondly network game coding is a sheer nightmare. Might I suggest starting with something a tad easier? Simply creating a client and server on the same machine that does nothing more than a simple chat. Just learn to had send and receive data as well as to build on that and have a good data management structure. Blindly jumping into projects like this always ends poorly. If you cant trap a MAV at this early of a stage, just image what it will be like when there are a lot of clients sending tons of packets everywhere. Just some friendly advise. If you want to continue with this however, might I suggest running in Debug mode and atleast figuring out where it is MAVing on your friends end? -Scott |

| that's what this code is basically is.. a simple chat.. and I have worked on a game with network coding before with my Soul Shooter Online game.. so I'm not new with Network coding.. (TCP) I'm just using this BlitzPlay lite.. which is UDP.. and I'm learning how to use it.. and My fault with the code indenting.. |
