                  double y,
                  double power,
                  String ownerName,
                  String victimName,
                  boolean isActive,
                  int bulletId)

  Called by the game to create a new `Bullet` object

  Parameters:
    `heading` - the heading of the bullet, in radians.
    `x` - the starting X position of the bullet.
    `y` - the starting Y position of the bullet.
    `power` - the power of the bullet.
    `ownerName` - the name of the owner robot that owns the bullet.
    `victimName` - the name of the robot hit by the bullet.
    `isActive` - `true` if the bullet still moves; `false` otherwise.

Method Detail

### equals

    public boolean equals(Object obj)

  Overrides:
    `equals` in class `Object`

### hashCode

    public int hashCode()

  Overrides:
    `hashCode` in class `Object`

### getHeading

    public double getHeading()

  Returns the direction the bullet is/was heading, in degrees (0 <= getHeading() < 360). This is not relative to the direction you are facing.

  Returns:
    the direction the bullet is/was heading, in degrees

### getHeadingRadians

    public double getHeadingRadians()

  Returns the direction the bullet is/was heading, in radians (0 <= getHeadingRadians() < 2 * Math.PI). This is not relative to the direction you are facing.

  Returns:
    the direction the bullet is/was heading, in radians

### getName

    public String getName()

  Returns the name of the robot that fired this bullet.

  Returns:
    the name of the robot that fired this bullet

### getPower

    public double getPower()

  Returns the power of this bullet.

  The bullet will do (4 * power) damage if it hits another robot. If power is greater than 1, it will do an additional 2 * (power - 1) damage. You will get (3 * power) back if you hit the other robot.

  Returns:
    the power of the bullet

### getVelocity

    public double getVelocity()

  Returns the velocity of this bullet. The velocity of the bullet is constant once it has been fired.

  Returns:
    the velocity of the bullet

### getVictim

    public String getVictim()

  Returns the name of the robot that this bullet hit, or `null` if the bullet has not hit a robot.

  Returns:
    the name of the robot that this bullet hit, or `null` if the bullet has not hit a robot.

### getX

    public double getX()

  Returns the X position of the bullet.

  Returns:
    the X position of the bullet

### getY

    public double getY()

  Returns the Y position of the bullet.

  Returns:
    the Y position of the bullet

### isActive

    public boolean isActive()

  Checks if this bullet is still active on the battlefield.

  Returns:
    `true` if the bullet is still active on the battlefield; `false` otherwise
