PiRocks

I am an experienced Java programmer. As you can guess, I love pi ( and also pie). In RoboRumble, I use the package name "hacker".

I am using "work-around" methods for my robots to make them better as well as find security glitches.

Hacker Robots

Right now my only robot is Destroyer. It is a 1-v-1 and Melee robot. Unfortunately, it was built and tested using Robocode v1.7.2.1 Beta, which has a different SecurityManager. Because of this my work-a-round method to create more threads doesn't work, resulting in auto disqualification. I am trying to fix this, but my next update will probably take a while.

Glitches

1.6.1.4 Glitches

So far, the only major glitch I have found is that you can cheat the SecurityManager by achieving a "SafeContext". One easy way to do this is using the following Class...

double bulletD = 0;
int round = scan.round;
double x = 0, y = 0;
while (M.sqr(bulletD) < Point2D.distanceSq(x, y, last.distance, 0)) {
	bulletD += bulletV;
	x += scan.relativePoint.getX();
	y += scan.relativePoint.getY();
	scan = scan.next;
	if (scan == null || scan.round != round)
		return null;
}
Point2D newEnemyLocation = new Point2D.Double(x, y);
newEnemyLocation = rotate(newEnemyLocation, last.heading);
newEnemyLocation = new Point2D.Double(newEnemyLocation.getX()
		+ r._enemyLocation.getX(), newEnemyLocation.getY()
		+ r._enemyLocation.getY());
if (!_fieldRect.contains(newEnemyLocation)) {
	return null;
}
