Robocode robot in Scala + Akka

[Fabio Oliveira]

Hi all,

I hope this is the right channel to announce that, I was always a Robocode
fan but I never contributed... What I want to change a little bit today.

I created a robot that uses the Robot API to communicate to a remote
"pilot", using Scala + Akka.

https://github.com/fbdo/robocode-akka

It was a interesting exercise to make it work, and now I am applying those
ideas to coach some team members in how to use Akka in a fun way.

Thanks for all the hard work, I hope my small contribution show itself
useful.

Regards.
F.

Hi Fabio,

interesting! Few comments
- the robocode robot API could be implemented via interfaces, if that
makes your life easier.
See
https://github.com/robo-code/robocode/tree/master/robocode.api/src/main/java/robocode/robotinterfaces
- the internal communication inside of the robocode engine is also passing
messages. To make it really fast it is only one message per game turn.
See
https://github.com/robo-code/robocode/blob/master/robocode.core/src/main/java/net/sf/robocode/peer/ExecCommands.java
See
https://github.com/robo-code/robocode/blob/master/robocode.core/src/main/java/net/sf/robocode/peer/ExecResults.java
Those messages are synchronous, the robot is blocked between turns.
It could be 10K messages per second.

I would like to ask if you could explain how it behaves in asynchronous
way.
I guess it means that robot would proceed to next round even without any
new command, right ?
Does it mean that you could skip many of the rounds/events ?
Could messages arrive out of order ?
Could you describe consequences of such design for the game play ?
What are the lessons you learned with your colleagues about Akka /
asynchrony ?
Does Akka allow you any new tricks with teams of robots ?

I suggest that you also add your project as new page to http://robowiki.net/

Thanks
Pavel
