    Default help with board game assignment

    I was given this assignment:
    For this assignment, your job is to create a kind of lobotomized version of a board game (such as Monopoly) called Opoly.

    Opoly works this way: The board is a straight linear track of variable length (you determine the length when you start up the game). There is only one playing piece, which begins the game just off the board, at position 0. Thus, if the board length is 20, then the board positions start at position 1 and end at position 20. To finish the game, the piece must land exactly on the last cell of the board (e.g., cell 20 in the example above).

    The object of the game is to acquire reward. The reward amount is initialized to 12. If your board piece lands on a board cell that is divisible evenly by 5, your reward doubles. However, if your piece lands one cell shy of the final board cell, your reward is reduced to 1/5 of its current value (via integer division), and your piece must go back to the start position - position 0. Note, though, that if the position of the last cell is divisible evenly by 5, then reward is doubled just before the game ends.

    In Opoly the game piece advances via a spinner - a device that takes on the values 1-2-3-4-5 at random, with each advance value equally likely.

    Two additional rules:

    1) if a spin would move the piece beyond the end of the board, the piece should not advance at all (thus, if the piece is at location 18 of a 20 cell board, and if the spinner spins a 5, this is counted as a move but the piece remains at location 18.) If a piece doesn't move at all, its current reward amount should remain unchanged, even if the piece sits at a location that is divisible evenly by 5.

    2) if the next to last board location is divisible by 5, and if the piece lands on this location, the reward is reduced to 1/5 of its current value only - the reward is NOT also doubled. Example: the board size is 26, and the piece is at location 23, with reward 30. Suppose the spinner spins a 2. This puts the piece on the next to the last location on the board (25). This resets the reward to 6 = 30 * 1/5, and places the piece at location 0. Even though location 25 is divisible by 5, no doubling happens.

    and given this driver:
    import java.util.*;
     
    public class OpolyDriver{
     
      public static void main(String[] args){
        System.out.println("Enter an int - the size of the board");
        Scanner s = new Scanner(System.in);
        int boardSize = s.nextInt();
        System.out.println("Board Size: " + boardSize);
        Opoly g = new Opoly(boardSize);
        g.playGame();
      }
    }

    This is the code that I wrote to go with the driver:
    import java.util.*;
     
    public class Opoly{
     
      private int width;
      private  int spinner;
      private int o;
      int[] opoly;
      private int currentPos;
      private int moves;
      private int reward;
      private int round;
     
     public Opoly(int o){
       this.o = o;
       opoly = new int[o];
       currentPos = 0;
       reward = 12;
     }
     
     public void spin(){
     spinner = (int)(Math.random()*6);//generates a random integer between 1 and 5 and stores it in spinner
     }
     
      public void move(){
        currentPos = currentPos+spinner;
      }
     
      public int spinAndMove(){
        round=0;
        while(currentPos < opoly.length-1){
        spin();
        move();
        round++;
        if(currentPos % 5==0){
          reward=reward*2;
        }
        if(currentPos==opoly.length-1){
          currentPos=currentPos;
          break;
        }
        if(currentPos > opoly.length-1){
          currentPos=currentPos;
          round++;
        }
        if(currentPos==opoly.length-2){
          currentPos=0;
          reward=reward/5;
      }
        if(currentPos % 5==0)
          reward=reward*2;
      }
        return round;
      }
      public void isGameOver(){
        if(moves==opoly.length-1)
          System.out.println("game over");
      }
     
      public void drawBoard(){
        while(opoly.length<currentPos){
          System.out.print('*');
          if(opoly.length>currentPos){
            System.out.print('*'+reward);
          }
          else
            System.out.print('O');
        }
        }
     
      public void displayReport(){
        isGameOver();
        System.out.println("Total rounds: "+round);
        System.out.println("Total reward: "+reward);
      }
     
       public void playGame(){
         while(currentPos !=opoly.length-1){
           spinAndMove();
           drawBoard();
         if(currentPos==opoly.length-1){
           drawBoard();
         displayReport();
         break;
         }}
       }

    This only prints out the end result of the game, but doesn't print out the drawBoard method. Any help is appreciated!

    I guess you're in the same class as this guy: Having trouble figuring out this method. Involves while-loops!

    At least on my screen, you didn't post the code that you need help with. (On iDevice, so it may just be the scroing) Either way, have you tried going through the code on pencil and paper? Write down all your variable (I actually have gotten quite fond of putting each variable on a flashcard then stacking the variables in the same class next to each other; however that can get to be a lot of flashcards if you have a lot of variables) , cross out/erase the variable and put the new value if it changes, and see if your code still works? Then figure out the problem method/loop, and then ask for help if you still can't figure it out. You don't need to show what each variable is unless that variable is a problem. EG you have a py triple method, that is initiated for some reason. Instead of showing how the variables are initialized, write the precondition, and what the postcondition/return value should be.

    /*Preconditon: A and B are two positive doubles
     *Returns the hypotenuse using the py theorem. 
    */
    public double getHypot()
    {
      return Math.sqrt(A*A + B*B);
    }
