Homework 4
(40 points)
This assignment will be programmed individually.
PRELIMINARIES
So that you don’t spend large amounts of time writing code, I have supplied the starter code in Java. I
realize this isn’t convenient for everyone, but you should be able to use a C++ subset of Java for what
you are asked to do for this assignment. I use JCreator to run the code. A separate document (posted
with this one) tells you how to download and use JCreator.
Posted on the website is sample code which sets up the game of Liar’s dice and plays it with up to six
random players. Study the code to see how it is implemented. Study the posted rules as well so you
see how scoring occurs. In the GUI, you can see the values of both the visible and hidden dice, but
the players do not see the hidden information. The code contains a director for dice images and a
directory of sounds. If you may an illegal bid, you get the donkey sounds. When you extract the data
from Home4.zip, do make sure you retain the directory structure, as the program is expected it.
The Action class records the moves of the game. Basically, your choices are either to increase the
current bid or challenge the current bid. For security purposes, I do not let you keep your own dice, so
you have to tell me what you want to reroll. For ease of programming, you just tell me what NOT to
reroll. For example, if you say keep=6, I make all hidden ones and sixes visible, and reroll the rest. I
realize I have limited your choices, but hopefully, this limitation is reasonable.
class Action{
boolean challenge; // True if action is to challenge current bid
int count; // How many of value you are bidding
int value; // Value of the dice you are bidding
int keep; // which value to keep in rerolling, 0 means keep all
Action(boolean c) {challenge = true; count = value = keep = 0;}
Action(int c, int v)
{ count =c; value = v; keep = 0; challenge = false;
}
Action(int c, int v, int r)
{ count =c; value = v; keep = r; challenge = false;
}
//For those of you unfamiliar with Java, the toString function is the conventional way to allow a class
//to print its contents. While sophisticated printing would want something fancies, toString is useful
//for debugging.
public String toString(){
if (challenge) return "Challenge";
if (reroll >0) return "Bid " + count + " of " + value + " **REROLL " + reroll;
return "Bid " + count + " of " + value;
}
}
You are to implement the Player interface for three types of players.
