My code snippets
- During my researches in Robocode I created many educating and interesting codes, which I'd like to share with you.
- Many places I use variables called 'hot' and 'absB'. They are exactly what their names mean: Head-on angle and Absolute Bearing, both in radians.
- The codes are not squeezed, they are supposed to be readable and obvious.
Quick Linear Targeting with Angular Velocity
- This works quite well, but it's not smaller and a bit less accurate than the popular latvel-type. Otherwise, this shows very spectaculary what exactly Angular Velocity is.
public double do_Angular_Velocity_Gun(ScannedRobotEvent e){
double av = (e.getVelocity()*Math.sin(e.getHeadingRadians()-absB))/e.getDistance();
return hot+av*(e.getDistance()/bulletVel);
}Quick Linear Targeting with Maximum Escape Angle
- This one is even less accurate but an interesting use of Maximum Escape Angle. ;)
public double do_MaximumEscapeAngle_gun(ScannedRobotEvent e){
double lateralDir = Math.signum(e.getVelocity()*Math.sin(e.getHeadingRadians()-absB));
double mea = Math.asin(8.0/bulletVel);
return hot + mea*lateralDir;
}
