If indeed Robocode manages to completely sandbox every robot, it would seem I have wasted a lot of time working on a problem that doesn't really exist. Robocode informational pages should state this upfront, as it is atypical behavior for a Java-based system.

Revision as of 20:28, 7 June 2011
A ran a new test tonight on static data handling. Tonight it appears as though static variables are not shared -- as if each robot runs on it's own JVM. This is fascinating, as I sware I have had problems with this before, and I even ran a test not that long ago that seemed to confirm the issue. I will need to do more testing to fully understand what is going on. Maybe it was an issue for an older version of Robocode. Not sure. I will have to run more tests. Skotty 05:10, 2 June 2011 (UTC)

A little note on drives and guns in the Xander framework -- a CompoundDrive or a CompoundGun allow multiple drives or guns to be chosen between using a DriveSelector or GunSelector respectively. It should be noted that CompoundDrives or CompoundGuns can be nested. What this does is creates a decision tree, with CompoundDrives or CompoundGuns being the branches. This might look something like the following (and is the general plan for drives for XanderCat 3.2). (Although I don't show it in the example, a CompoundDrive or CompoundGun can have any number of drives or guns immediately below; it is not limited to only having two)
