  • Constructor Details

    • HitByBulletEvent

      public HitByBulletEvent(double bearing, Bullet bullet)
      Called by the game to create a new HitByBulletEvent.
      Parameters:
      bearing - the bearing of the bullet that hit your robot, in radians
      bullet - the bullet that has hit your robot

  • Method Details

    • getBearing

      public double getBearing()
      Returns the bearing to the bullet, relative to your robot's heading, in degrees (-180 invalid input: '<' getBearing() invalid input: '<'= 180).

      If you were to turnRight(event.getBearing()), you would be facing the direction the bullet came from. The calculation used here is: (bullet's heading in degrees + 180) - (your heading in degrees)

      Returns:
      the bearing to the bullet, in degrees

    • getBearingRadians

      public double getBearingRadians()
      Returns the bearing to the bullet, relative to your robot's heading, in radians (-Math.PI invalid input: '<' getBearingRadians() invalid input: '<'= Math.PI).

      If you were to turnRightRadians(event.getBearingRadians()), you would be facing the direction the bullet came from. The calculation used here is: (bullet's heading in radians + Math.PI) - (your heading in radians)

      Returns:
      the bearing to the bullet, in radians

    • getBullet

      public Bullet getBullet()
      Returns the bullet that hit your robot.
      Returns:
      the bullet that hit your robot

    • getHeading

      public double getHeading()
      Returns the heading of the bullet when it hit you, in degrees (0 invalid input: '<'= getHeading() invalid input: '<' 360).

      Note: This is not relative to the direction you are facing. The robot that fired the bullet was in the opposite direction of getHeading() when it fired the bullet.

      Returns:
      the heading of the bullet, in degrees

    • getHeadingDegrees

      @Deprecated public double getHeadingDegrees()
      Deprecated.
      Use getHeading() instead.
      Returns:
      the heading of the bullet, in degrees

    • getHeadingRadians

      public double getHeadingRadians()
      Returns the heading of the bullet when it hit you, in radians (0 invalid input: '<'= getHeadingRadians() invalid input: '<' 2 * PI).

      Note: This is not relative to the direction you are facing. The robot that fired the bullet was in the opposite direction of getHeadingRadians() when it fired the bullet.

      Returns:
      the heading of the bullet, in radians

    • getName

      public String getName()
      Returns the name of the robot that fired the bullet.
      Returns:
      the name of the robot that fired the bullet

    • getPower

      public double getPower()
      Returns the power of this bullet. The damage you take (in fact, already took) is 4 * power, plus 2 * (power-1) if power > 1. The robot that fired the bullet receives 3 * power back.
      Returns:
      the power of the bullet

    • getVelocity

      public double getVelocity()
      Returns the velocity of this bullet.
      Returns:
      the velocity of the bullet
