Advancing Velocity
From RoboWiki
Advancing Velocity is the speed at which your opponent is moving toward you (perpendicular to Lateral Velocity). When you stay still, RamFire usually has an Advancing Velocity of 8 and MyFirstRobot usually has an Advancing Velocity of 0. A robot moving straight away from you would have an Advancing Velocity of -8.
Calculation
A simple formula for advancing velocity is:
double advancingVelocity = -Math.cos(e.getHeadingRadians() - (e.getBearingRadians() + getHeadingRadians())) * e.getVelocity();
Where e is a ScannedRobotEvent.
