I've updated my blog to reflect the current development status...did not make the progress I wished to realize but that's life...

I'm excite to hear that you're working on this. I played RSR an untold number of hours in my youth. Lots of great memories. :)

Sorry for being quiet the last months but due to other personal issues I have not further worked on the project for the last 2 months.

So, now I'm in the process to make the code base (apart from the UI) more portable and I hope I get this finished by this weekend.

Then the next goal is to have a basic TMA working :)

I've disabled my blog currently but nevertheless here are some updates of the current build: http://img4web.com/g/JAK2

The TMA is display-only and I do not know if it will remain....it is more or less a debugging tool for me. TMA is auto-working in the game

The main change is in the navigation UI....it displays now all major sensor data.
Active sonar also works now.

I've designed the rough components of the AI. Basically, there will be high level AI components ('goal-driven AI') but the actual AI (also of weapons) can be implemented in C# (only by me ;) but also in IronPython (by all)...IronPython is just Python, running on .NET....there is also a very good IDE freely available for it (Visual Studio Tools).

So, a more sophisticated version of the doctrine language approach in DW. Also the scenario/campaign generation will be implementable in IronPython....but that's future.

The next step is to create the possibility to fire a torpedo and also implement its logic.

I can be wrong, but wont it be better to write any performance critical code in a language such as C or C++ rather than C# (.net, python, ect)?

You can develop performance critical apps in .NET. In contrast to C++ and other languages, it is very 'easy' to develop an application running on multi-core systems. For example the backend is an own thread/can run on a core and the AI part can also be decoupled, that is running on another core.
