Class ch.jp.robwar.ReadOnlyMap

java.lang.Object
   |
   +----ch.jp.robwar.ReadOnlyMap

public class ReadOnlyMap
extends Object
implements Serializable, Cloneable

The ReadOnlyMap class allows access to all read and helper functions of the Map class, but doesn't let you alter it.

See Also:: Map

ReadOnlyMap(Map): Once the constructor is called, all allowed calls will be transmitted to the underlying map.

angleTowards(Position): Angle between (0,0) and the given position, in radians.
getBulletList(): Returns a Vector containing a copy of all the bullets in the map (of class Bullet).
getHeight(): Returns the height of the map
getRobotList(): Returns a Vector containing a copy of all the robots of the map (of class RobotInfo).
getWallList(): Returns a Vector containing a copy of all the walls of the map (of class LinearMapObject), including the walls surrounding the arena.
getWidth(): Returns the width of the map
lineSegmentsIntersect(LinearMapObject, LinearMapObject): Returns true if the two line segments intersect
lineSegmentsTouch(LinearMapObject, LinearMapObject, double): Return true if the two line segment are separated by a distance smaller than dist
lineSegmentTouches(LinearMapObject, Position, double): Returns true if the distance between the line segment and the point is smaller than radius
robotTouching(Position, double, int): Returns the number of the robot that is at a distance less than radius from pos, and whose number is different from except.
setBulletList(Vector): This method set the bullet list returned by getBulletList().
shortestTurn(double, double): Returns +/- (targetAngle-startAngle), depending on which is shorter.
touchesObstacle(Position, double, int): Returns true if an object, except the robot number exceptRobot is at a distance shorter than radius to the given position.
touchesWall(Position, double): Returns true if a linear object of internalList is at a distance shorter than radius to the given position.
traversesWall(LinearMapObject): Returns true if the given line segment goes through a wall
traversesWall(LinearMapObject, double): Returns true if the given line segment goes through a wall or comes to a distance closer than dist to it.

ReadOnlyMap

 public ReadOnlyMap(Map theMap) throws NullPointerException

Once the constructor is called, all allowed calls will be transmitted to the underlying map. Therefore, it is not necessary to rebuild the ReadOnlyMap if the Map changes.

setBulletList

 public void setBulletList(Vector newList)

This method set the bullet list returned by getBulletList(). It will not have any effect on the game and is only meant to be used internally.

getBulletList

 public Vector getBulletList()

Returns a Vector containing a copy of all the bullets in the map (of class Bullet). Modifying the list will not have any effect on the actual map.

getWallList

 public Vector getWallList()

Returns a Vector containing a copy of all the walls of the map (of class LinearMapObject), including the walls surrounding the arena. Modifying the list will not have any effect on the actual map.

getRobotList

 public Vector getRobotList()

Returns a Vector containing a copy of all the robots of the map (of class RobotInfo). Modifying the list will not have any effect on the actual game.

getWidth

 public double getWidth()

Returns the width of the map

getHeight

 public double getHeight()

Returns the height of the map

lineSegmentsIntersect

 public boolean lineSegmentsIntersect(LinearMapObject one,
                                      LinearMapObject two)

Returns true if the two line segments intersect

lineSegmentTouches

 public boolean lineSegmentTouches(LinearMapObject line,
                                   Position pos,
                                   double radius)

Returns true if the distance between the line segment and the point is smaller than radius

lineSegmentsTouch

 public boolean lineSegmentsTouch(LinearMapObject one,
                                  LinearMapObject two,
                                  double dist)

Return true if the two line segment are separated by a distance smaller than dist

traversesWall

 public boolean traversesWall(LinearMapObject traj)

Returns true if the given line segment goes through a wall

traversesWall

 public boolean traversesWall(LinearMapObject traj,
                              double dist)

Returns true if the given line segment goes through a wall or comes to a distance closer than dist to it.

touchesWall

 public boolean touchesWall(Position pos,
                            double radius)

Returns true if a linear object of internalList is at a distance shorter than radius to the given position.

robotTouching

 public int robotTouching(Position pos,
                          double radius,
                          int except)

Returns the number of the robot that is at a distance less than radius from pos, and whose number is different from except. If there is no such robot, returns -1.

touchesObstacle

 public boolean touchesObstacle(Position pos,
                                double radius,
                                int exceptRobot)

Returns true if an object, except the robot number exceptRobot is at a distance shorter than radius to the given position.

angleTowards

 public double angleTowards(Position target)

Angle between (0,0) and the given position, in radians. 0=east.

shortestTurn

 public double shortestTurn(double startAngle,
                            double targetAngle)

Returns +/- (targetAngle-startAngle), depending on which is shorter. The angles given in parameter can have any value; the return value will be between -Pi and Pi.
