Using SVN takes a bit to figure out. If you want to upload that is.
For those too lazy that just want to look at source, the web provider I'm using provides "trac", which is sort of a wiki/GUI/etc.
The Darwinbots C++ Source Trac.
If you go to view source, and click on a source file, you can see what Darwinbots code looks like at the moment. With syntax coloring and everything!
Neat, huh?
Right now you can run Darwinbots as a console application and have it iterate a number of cycles. You'll have to modify the routine that tries to find lastexit.set if your Darwinbots isn't in C:\DarwinbotsII\
How much is done? Well, the entire Robots module is done, as is senses module, and a number of library type functions like vector math and random numbers, etc.
Definately check it out.
