A method of Targeting that simply chooses a random angle among the angles that could possibly hit the opponent. Some successful NanoBots use this firing method. Its implementation is very small and for unpredictable movements, it will give a consistent hit percentage.
Example
public void onScannedRobot(ScannedRobotEvent e) {
double randomGuessFactor = (Math.random() - .5) * 2;
double bulletPower = 3;
double maxEscapeAngle = Math.asin(8.0/(20 - (3 * bulletPower)));
double firingAngle = randomGuessFactor * maxEscapeAngle;
double absBearingToEnemy = e.getBearingRadians() + getHeadingRadians();
setTurnGunRightRadians(Utils.normalRelativeAngle(
absBearingToEnemy + firingAngle - getGunHeadingRadians()));
fire(bulletPower);
}
A simpler solution
A simpler method is to assume that the enemy is traveling in a circle around you, which is often true among NanoBots and 1-vs-1 bots. If the enemy is traveling in a circle around you, the maximum distance it can cover before a bullet reaches it is enemy velocity / bullet velocity (in radians). For example, a power 3.0 bullet fired at an enemy going at full speed should be fired at a bearing offset between -8/11 and +8/11.
