Historical Velocity Recall

A method of targeting that uses the most common enemy velocity as input to a linear targeting or circular targeting algorithm. The effectiveness of this targeting strategy can be greatly increased by implementing Segmentation.

Example using linear targeting

int[] _velocityCounts = new int[9];

public void onScannedRobot(ScannedRobotEvent e) {
    int goingBackwardsMultiplier = (e.getVelocity() < 0 ? -1 : 1);
    int enemyAbsVelocity = (int)Math.round(Math.abs(e.getVelocity()));
    _velocityCounts[enemyAbsVelocity]++;

    int mostCommonVelocity = 0;
    int mostCommonVelocityCount = _velocityCounts[0];
    for (int x = 1; x < 9; x++) {
        if (_velocityCounts[x] > mostCommonVelocityCount) {
            mostCommonVelocityCount = _velocityCounts[x];
            mostCommonVelocity = x;
        }
    }

    fireWithLinearTargeting(e.getHeadingRadians(), 
        mostCommonVelocity * goingBackwardsMultiplier);
}
