I would like to learn more about how OpenSim and of course Second life works,

Looking at the code is all well and good but some form of documentation would be helpful, What about information on the SL protocol stack as used by the SL viewer?

Its hard to help or do anything if there is no real information on how to actually do something, a sequence diagram or usecase might help?

Dev Docs off the front page:

Developer Documentation - OpenSim

Also, code docs at OpenSim: Main Page

actually Adam, the protocol stack is not well explained anyplace that i could find, and not being a c# coder, the source is hard to figure anything out from. (wishes it was written in c++)

The reason i asked is because i want to port it to Java, as I hate C# basically because i cannot compile it even though i have a working C# compiler because the makefile is designed to only work with Microsoft Visual Studio and not the .NET compiler you can get for FREE....

I thought this was supposed to be FREE software...

With attitudes like this, why doesn't everyone spend all their time and energy making things for free!

There's a free version of Visual Studio anyway, which I've used to compile OpenSim myself with no issues (as I do not have a full version).

I don't know why you want to port anything to Java unless you hate yourself, but that's my experience.

Visual Studio 2008 Express Editions

The express editions of Visual Studio are very nice. I compile the SL Viewer itself with one of em (The 2005 Express)

Oh, language ports are always a nice thing. It always attracts those who are more at home with the language ported to, and each langauge has its strength. Of course the porting itself will be hell.

runprebuild builds both VS solution files, and NAnt build files for Mono. If you utilize Monodevelop or Sharpdevelop, you can use either.

But frankly, on windows - runprebuild.bat then compile.bat, tends to be a lot easier.

/me laughs and wants to see Opensim and viewer in Java

Makoto · 03-25-2009, 05:43 AM

opensim itself is a server item, this is ideal for multithreading on JVM, Java 1.6 is fast enough to actually run that side of the sim, that would mean it would run on Linux and Mac and Windoze with no problems.

Viewer, sorry that would be way hard and i am not a J3D programmer.

Joshua Nightshade · 03-25-2009, 05:47 AM

OpenSim already runs on Windows, Mac and Linux with no problems.

You can use mono to compile it and run it just fine on various platforms, and yes - that includes compiling it on windows too if you're a masochist.

Actually it was done.

A certain company did a internal port of OpenSim to Java in their early experimentations a few years ago, with very ... mixed results. Suffice to say they abandoned it and ended up just hiring developers to work on the C# version.

Was that a manual porting effort, one of those cool automated C#-to-java source code converters or bytecode conversion?

**Adam Zaius** · 03-26-2009, 11:57 PM

Manual effort.

Opensim in Erlang would be more ideal, as for the viewer it dosnt really matter, c++ is fine
