Writing Robots in Python / Jython?

[Markus Lutzer]

Hello,
I'm looking for a possibility to write a Robocode-robot in Python. Thus
I tries Jython but without success. The robot Pambo.py looks like this:

>---
from robocode import *

class Pambo(Robot):

        def listMods(self):
                return "net.sourceforge.robocodeng.mods.ShotgunMod"

        def run(self):
                print "Rambo is running..."
                while True:
                        ahead(100) # Move ahead 100
                        turnGunRight(360) # Spin gun around
                        back(100) # Move back 100
                        turnGunRight(360) # Spin gun around
               
        def onScannedRobot(ScannedRobotEvent):
                fire(1)

        # We were hit!  Turn perpendicular to the bullet,
        # so our seesaw might avoid a future shot.
        def onHitByBullet(HitByBulletEvent):
                turnLeft(90 - HitByBulletEvent.getBearing())
>---

Compilation by typing "jythonc -A ~/RobocodeNG/RobocodeNG.jar Pambo.py"
succeeded. I started Robocode successfully with
"java -cp RobocodeNG.jar:/usr/share/jython/jython.jar:.
robocode.Robocode" but the message "sample.Pambo : Something is wrong
with this class: java.lang.NoClassDefFoundError: sample/Pambo (wrong
name: Pambo)" showed up. My Python-robot does not start when selected
for a battle.

I use Ubuntu Linux, Sun's Java 1.5 and Jython 2.1.

Any ideas how to make my robot runnable? Other suggestions how to use
Python with Robocode?

Regards, Lutz

I can run jython robocode-robot!
Some changes of course.

1. Compile it to a package with -p:
    jythonc -p sample pambo.py
    You can see "package sample;" in the resulting pambo.java.
2. Add self argument to class member function def, such as:
    def onScannedRobot(self, ScannedRobotEvent):
3. Add self to function calls, such as:
    self.ahead(100)
