Bridging robocode.control.RobocodeEngine to .NET

[Jason Hyland]

Hi,

I'm looking at how best to write integration tests for my robots in .NET. I don't see anything in the .NET API, but I have found the robocode.control.RobocodeEngine which appears to do exactly what I need. So, I'm trying to bridge the classes using jni4net.

I guess the correct approach is to extend the bridging code in robocode itself, but I know next to nothing about Java, and I certainly don't feel confident enough yet to go poking around in the source. So, for now, I though it best to play in a safe sandbox :)

My initial approach is to attempt to bridge robocode.jar (from robocode\libs), which I believe contains the classes I need. Using jni4net 0.0.0.8 I run

c:\robocode\libs\proxygen robocode.jar -wd work

this creates a work directory and pumps out

I then cd to the work directory and run the build.cmd and get the following error

I looked at the source under plugin\dotnet and looked at the robocode.proxygen.xml and became even more confused! A pointer in the right direction would be appreciated!

Hi Jason,

I experimented with the same thing last night as well. I got have it
up & running, but I spent whole night on it and I know what I'm doing.
So I realized that it was bit unfair to throw you into that with bare
hands.

Please see and comment on this
http://code.google.com/p/robocode/source/detail?r=3482

Download preview is there, Alpha quality.
http://robocode.sourceforge.net/download/robocode-1.7.2.2-Alpha-setup.jar
http://robocode.sourceforge.net/download/robocode.dotnet-1.7.2.2-Alpha-setup.jar

It contains upgraded jni4net with support for CLR 4.0
And I drafted first F# robot as well.

Hi Flemming,

I hope you don't mind I jumped into your 1.7.2.2 branch with this all.
Should be zero impact for Java-only users.

Cheers
Pavel

Hi guys,

I am very happy that Robocode is now upgraded to CLR 4.0 and we are
able to support F# (a very cool language, that I think is excellent
for robot modelling).
And it is perfect that it has been put in 1.7.2.2 (future release) as
I am working on stabilizing 1.7.2.1 (fixing found bugs) before the
final release.

Pavel: I haven't reviewed your changes yet, but will look at it later
(when I have handled all my mails that have stacked up during my
vacation in Spain).
But I am very confident with your changes. :-)

Cheers,
- Flemming
