Named after the Doppler Effect

It is the same as BulletDoubling (Old Wiki)

Example of waves that reach enemy at the same time

The picture to the right shows a group of waves clustered together.

How it Works

Fire a group of bullets that reach your target at the same time, either by moving the robot, changing bullet power, or a combination of both.


Concept

Use only on stationary targets (shows concept when farther away).



package wiki;
import robocode.*;

public class BlueShift extends AdvancedRobot
{
	double turns;
	double time;

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

	public void onScannedRobot(ScannedRobotEvent e)
	{
		double absoluteBearing = e.getBearingRadians() + getHeadingRadians();
		double distance = e.getDistance();
		setTurnRightRadians(robocode.util.Utils.normalRelativeAngle(absoluteBearing - getGunHeadingRadians()));
		turns -= getTime() - time;
		time = getTime();
		if (turns <= 0) {
			time = getTime();
			turns = distance / 11;
			setFire(3);
		} else {
			setFire((distance / turns - 20) / -3);
		}
	}
}
