help with a hunt the wumpus game

807600Nov 29 2007 — edited Nov 30 2007
I accidently posted this question on the wrong section so i'm posting it again here.

i'm trying to write the hunt the wumpus game with simple conditions: (check-marked the ones i already accomplished)
[x]the pits will be placed randomly
[x] the wumpus is placed in the maze randomly (not sure if i did that one correctly)
[x] the player starts on the lower left of the maze row 3 col 0
-the player will only have 1 chance to shoot the Wumpus
[x]if the player is close to the Wumpus then there would be a prompt saying there is stench around
[x]if the player is close to a pit then she/he will be prompted that there is a breeze.
-if the player falls in a pit or gets eaten by the wumpus the game will be over and the map of the maze will be shown. I used 0 for empty cells and p for pits and w for wumpus in the array.

There is some problem with the program i've written so far but i don't know how to fix it. also, i don't know how to check if the wumpus will be in the direction the player wants to shoot. i'd appreciate any suggestions

import java.util.*;
public class playWumpus 
{
    //initMaze METHOD
    //put the pits and wumpus into the world
    public static void initMaze(char [][] maze)
    {
        Random r = new Random();
    
        for (int row = 0; row <4; row ++)
        {
            maze[row][col] = '0';    <<<<<<there is a problem here: col cannot be resolved
        }
        int pitRow, pitCol;
        for (int pitNum = 0; pitNum <4; pitNum++)
        {
            pitRow = r.nextInt(4); //randomly choose row
            pitCol = r.nextInt(6); //randomly choose column
            if (pitRow == 3 && pitCol == 0)//start location
            {   
                pitCol=5;
            }
        }
        maze [pitRow][pitCol] = 'p'; //places the pits in the maze randomly
        maze [r.nextInt(4)][r.nextInt(6)] = 'w'; //places the wumpus randomly in the maze
    }// end of Maze method

    //feel breeze, smell stench, nothing.
