Class Location

java.lang.Object

aic2021.user.Location

public class Location
extends java.lang.Object

Class that represents the location of each of the tiles. The x-coordinate increases to the east (to the right at the screen), while the y-coordinate increases to the north (upwards at the screen). In order leak the least possible amount of information about the limits of the map, the bottom-left position of the map is set at a default value (x,y), which depends on the map, and all other locations are numbered accordingly (i.e. its adjacent location to the right would be (x+1, y)). The value of x and y is guaranteed to be between 0 and 1000.

Method Detail

add

public Location add(Direction dir)

Returns the location after moving from the current location following a given direction. There is a penalty for giving a null direction. It costs 2 energy.

Parameters:

dir - Given direction

Returns:

the location after moving from the current location following a given direction

add

public Location add(int _x,
                    int _y)

Returns the location after moving from the current location following vector (_x,_y). It costs 2 energy.

Parameters:

_x - x-component.

_y - y-component.

Returns:

the location after moving from the current location following vector (_x,_y).

directionTo

public Direction directionTo(Location loc)

Returns the direction that gets the closest to a given location. There is a penalty if the given location is null. It costs 5 energy.

Parameters:

loc - Given location.

Returns:

the direction that gets the closest to a given location.

isEqual

public boolean isEqual(Location loc)

Returns if the given location is equal to this (in value). It costs 1 energy.

Parameters:

loc - Given location

Returns:

true if and only if both locations have equal coordinates.

distanceSquared

public int distanceSquared(Location loc)

Returns the squared euclidean distance between this location and the given one. There is a penalty if the given location is null. It costs 5 energy.

Parameters:

loc - Given location.

Returns:

the squared euclidean distance between this location and the given one.

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
