Re: update the download jar?

The labs have a new image here are Portland State University. It presents all the programs I use in class in one folder. Bottom line is that students in my Lego Robotics class got into robocode. Unfortunately, my "core" dumped robocode after a term on "non-use". So it's going to take me a while to reload robocode and familiarize myself with it. Anyway...
We got into this normalRelativeAngle compile error again.
The robot is Tracker and the error is "No accessible method"
I tried combinations of the following:
1. Util.normalRelativeAngleDegrees()
2. Util.normalRelativeAngle()
3. import static robocode.util.Util.normalRelativeAngle
4. import static robocode.util.Util
5. import without the static
Then I ran out of time.
The kids were also getting errors relating to BulletHitBullet in MyFirstRobot, which does not use BulletHitBullet. I'll have to look that up later.
Anyway, if someone more knowledgeable can please help a harried teacher to fix the bugs, please accept my sincerest gratitude.
Best,
Edwin
