public class Player
extends Item

This mutable class represents a player. A player has an amount of cash, a speed, a location, a current Route, and usually a destination. Strategies don't have access to Player objects: instead they work with immutable PlayerView objects.

See Also:: Location, PlayerView

Player(String, int, Strategy, Junction): creates a player, with the given name, index, strategy, and initial terminus; cash=INITIAL_CASH; speed=slow; currentRoute=none.

Method Index

equals(Object): compares two objects.
getCash(): returns the player's cash.
getCurrentRoute(): returns the player's current Route, or null if none.
getDestination(): returns the player's destination.
getLocation(): returns the location of the player.
getOrigin(): returns the player's origin.
getStrategy(): returns the player's Strategy.

initialize(Junction): initializes a player, to the given terminus; cash=INITIAL_CASH; speed=slow; currentRoute=none.
isFast(): indicates whether the player is fast (has a Right-of-Way.)
move(int, Route[]): moves the player toward his destination, according to the segments chosen by the strategy.
noteArrival(Board): notes the players arrival at a destination.
setDestination(Junction): sets the player's destination to dest.
setSpeed(boolean): sets the player's speed.

Constructors

Player

 public Player(String name,
               int index,
               Strategy stra,
               Junction loc)

creates a player, with the given name, index, strategy, and initial terminus; cash=INITIAL_CASH; speed=slow; currentRoute=none.

Methods

equals

 public boolean equals(Object ob)

compares two objects.

Overrides:: equals in class Item

getStrategy

 public Strategy getStrategy()

returns the player's Strategy.

getCash

 public int getCash()

returns the player's cash.

isFast

 public boolean isFast()

indicates whether the player is fast (has a Right-of-Way.)

getOrigin

 public Junction getOrigin()

returns the player's origin.

getDestination

 public Junction getDestination()

returns the player's destination. But returns null if the player is at a terminus and hasn't selected his next destination.

getCurrentRoute

 public Route getCurrentRoute()

returns the player's current Route, or null if none.

toString

 public String toString()

returns a string representation of the player. It shows name, cash, and destination.

Overrides:: toString in class Object

initialize

 public void initialize(Junction loc)

initializes a player, to the given terminus; cash=INITIAL_CASH; speed=slow; currentRoute=none.

getLocation

 public Location getLocation()

returns the location of the player. This is a mutator, because changing the return value alters the player.

incrementCash

 public void incrementCash(int amt)

adds a value to the player's cash. amt may be negative.

setSpeed

 public void setSpeed(boolean fast)

sets the player's speed.

setDestination

 public void setDestination(Junction dest)

sets the player's destination to dest. dest may be null.

noteArrival

 public void noteArrival(Board bo)

notes the players arrival at a destination. Updates his cash, nulls his destination and currentRoute.

move

 public int move(int distance,
                 Route newRoute[])

moves the player toward his destination, according to the segments chosen by the strategy. The player moves distance, or less if he arrives.

The return value RV indicates:

If RV < 0, he arrived at his destination.
If RV == 0, he didn't arrive, and has exhausted his roll.
If RV > 0, he didn't arrive, has RV distance to go, and has chosen a new route, stored in newRoute[0].

Parameters:: distance - the distance to travel; newRoute - result parm: the new route travelled
