BeerPoet, by PEZ, is yet another implementation of the "99 bottles of beer" poem in a programming language. As of this writing there are 709 published implementations:

http://www.99-bottles-of-beer.net/

BeerPoet actually got added to the project site: http://www.99-bottles-of-beer.net/language-robocode-494.html Cool huh? -- PEZ

Great, I want to try it. Where can I download it?

http://www.robocoderepository.com/BotDetail.jsp?id=1480

How competitive is it?

Beats SittingDuck. In fact it's designed to beat SittingDuck. 99 SittingDucks to be precise. In that sense it's my first competetive Melee bot. =) While it drinks SittingDuck beer it sings a song that's written in the output window.

How does it move?

It doesn't.

How does it fire?

On sight, HeadOnTargeting.

Where did you get the name?

It seemed like an appropriate name

Can I use your code?

Sure: Here it is:
package wiki.beer;
import robocode.*;
import java.awt.geom.Point2D;

// BeerPoet, one way to go about writing the 99-bottles-of-beer poem.
// By Peter Strömberg, http://robowiki.net/?PEZ
// For more info on the poem: http://99-bottles-of-beer.ls-la.net/
//
// Run this robot in Robocode.
// Put it against 99 SittingDuck and open its output window.

public class BeerPoet extends AdvancedRobot {
    private boolean hasStarted;

    public void run() {
        turnGunRightRadians(Double.POSITIVE_INFINITY); 
    }

    public void onScannedRobot(ScannedRobotEvent e) {
        if (!hasStarted) {
            printBottles();
            hasStarted = true;
        }
        setFire(3);
        setTurnGunRightRadians(0 - getGunTurnRemainingRadians());
    }

    public void onRobotDeath(RobotDeathEvent e) {
        printBottles();
    }

    private void printBottles() {
        out.println(bottles());
        if (getOthers() > 0) {
            out.println("Take " + (getOthers() == 1 ? "it" : "one") +
                " down, and pass it around");
            }
        else {
            out.println("Now they are all gone");
        }
    }

    private String bottles() {
        return bottles(getOthers()) + " on the wall, " + bottles(getOthers());
    }

    private String bottles(int bottles) {
        return (bottles == 0 ? "No" : "" + bottles) +
            " bottle" + (bottles == 1 ? "" : "s") + " of beer";
    }
}

What's next for your robot?

Dunno. Maybe someone else could write a Teams solution to the problem? Or maybe a bear drinker that rams it's opponents to death and drives funnier and funnier?

Comments, questions, feedback:

Feel encouraged to post your variation of a beer poet here.

Hey! This is pretty cool! Maybe you should write one that shoots down 99xsample.Walls, this way, you can sing "99 Robocode bots on the wall" :-) --Dummy

Yes, but Walls is a pretty strong bot. I have yet to make a bot that I can trust takes down 99 Walls every time. Please try. =) -- PEZ

I think 99 walls would take each other out for you quite efficiently :p -- Kuuran

Maybe so, but the poet must outsurvive all 99 Walls. That's not easy I think. -- PEZ

Yeah, finding an escape angle which a bullet isn't traveling along would be rather difficult, and it's far less fun if they're dying too fast for him to do his poem properly. -- Kuuran

A question. When I first wrote the poet I wrote it without the hasStarted boolean thingy. I simply called printBottles() from the run method. But it didn't work. It seemed like the function wasn't called at all then. Someone knows why? -- PEZ

ROFL! This is hilarious. Man. I've been sitting here for a couple hours now hitting Random Page and reading whatever comes up. Maybe I should go to bed... -- Vuen

Just thought I'd mention. Delete this if you like :). Anybody see any of their lucky numbers? -- Vuen

What is it showing? Doesn't the poet win all the rounds? I must admit I never really tried it with 99 bottles, just 5 or 6 or so... Shame on me. -- PEZ

Lol, it's not really showing anything. I was just bored at the time, so I felt like showing the scores. Heh... */me slaps himself* -- Vuen

Here is my Sonnet beerbot:

public class BeerSonnet extends AdvancedRobot {
	public void run() {
		setAdjustRadarForGunTurn(true); // 1

		setTurnRadarRight(Double.POSITIVE_INFINITY); // 2
		printBottles(); // 3
	}

	public void onScannedRobot(ScannedRobotEvent e) {
		setTurnRadarLeft(getRadarTurnRemaining()); // 4

		double absoluteBearing = getHeadingRadians() + e.getBearingRadians()
				+ (Math.random() < 0.5 ? 1 : -1)
				* (Math.random() / getOthers()); // 5
		turnGunRightRadians(Util.normalRelativeAngle(absoluteBearing
				- getGunHeadingRadians())); // 6
		fire(3); // 7
	}

	public void onRobotDeath(RobotDeathEvent e) {
		printBottles(); // 8
	}

	private void printBottles() {
		out.println(bottles()); // 9
		if (getOthers() > 0) {
			out.println("Take " + (getOthers() == 1 ? "it" : "one")
					+ " down, and pass it around"); // 10
		} else {
			out.println("Now they are all gone"); // 11
		}
	}

	private String bottles() {
		String bottleCount = bottles(getOthers()); // 12
		return bottleCount + " on the wall, " + bottleCount; // 13
	}

	private String bottles(int bottles) {
		return (bottles == 0 ? "No" : "" + bottles) + " bottle"
				+ (bottles == 1 ? "" : "s") + " of beer"; // 14
	}
}

It gets drunk and misses near the end of the bots. --AaronR
