It will be more fun if you do this instead:

public void doPaint(Graphics2D g) {
	g.setStroke(new java.awt.BasicStroke(2f));
	if (bot.getOthers() == 1) {
		double radius, arcSegment, segmentHeading;
		double time = bot.getTime();
		for (Wave w : waves) {
			if (w.paint) {
				radius = (time - w.ctime) * w.velocity;
				arcSegment = w.extent / NUM_WAVEBUCKETS;
				for (int i = 0; i < NUM_WAVEBUCKETS; i++) {
					segmentHeading = w.heading + w.clockwise * (arcSegment * i - w.extent / 2);
					g.setColor(Color.getHSBColor( // this is Hue, Saturation, and Brightness
						0.058333f,
						1.0f,
						(float) (0.15 + 0.85 * waveBuckets[w.segment][i] / bucketMax[w.segment])
					));
					g.draw(new Arc2D.Double(
						w.origin.x - radius,
						w.origin.y - radius,
						radius * 2,
						radius * 2,
						segmentHeading,
						arcSegment,
						Arc2D.OPEN
					));
				}
			}
		}
	}
}

Originally, that's what I did, but with more waves on the screen I was skipping turns. -- Synapse 14:37, 10 June 2009 (UTC)

Really? I think robocode allow unlimited time when you are drawing. » Nat | Talk » 14:43, 10 June 2009 (UTC)

Nope -- I noticed in one of the changelogs that painting is now done by the robot's thread and counts against your cpu time. Makes sense, since you can really put any code (movement, targeting, etc.) inside of onPaint(). Nice waves, by the way! --Darkcanuck 14:54, 10 June 2009 (UTC)

Yeah, v1.6.1 does. But later changelogs (1.6.2beta) state that "Bug [2214620]: Robots were paying CPU time for painting. Now Robocode gives a robot unlimited time when painting is enabled on UI (in the robot dialog) for that robot.". =) » Nat | Talk » 15:11, 10 June 2009 (UTC)
