move function, pset3

Question

I'm having trouble with my move funtion in the game of fifteen. For some reason the chosen tile and the adjecent zero won't swop places. I've been working on this function for too long and reaching out for help now. I eally hope somebody can help me out!

/** * If tile borders empty space, moves tile and returns true, else * returns false. */

bool move(int tile) { int temp;

if (tile == 0)
{
    return false;
}
for (int row = 0; row < d; row++)
{
    for (int column = 0; column < d; column++)
    {
        if (tile == board[row][column]) //checks array for tile
        {

            if (column > 0) //makes sure C does not acces any space to the left of 2D-array
            {
                if (board[row-0][column-1] == 0) // checks if blank space is left to tile
                {
                    temp = tile;     //switch the tiles
                    board[row][column] = board[row-0][column-1];
                    board[row-0][column-1] = temp;
                    return true;
                }
            }
            if (row > 0) //makes sure C does not access any space above 2D-array
            {
                if (board[row-1][column-0] == 0) // checks if blank space is above tile
                {
                    temp = tile;     //switch the tiles
                    board[row][column] = board[row-1][column-0];
                    board[row-1][column-0] = temp;
                    return true;
                }
            }
            if (column < d-1) //makes sure C does not access any space to the right of 2D-array
            {
                if (board[row+0][column+1] == 0) // checks if blank space is right to tile
                {
                    temp = tile;     //switch the tiles
                    board[row][column] = board[row+0][column+1];
                    board[row+0][column+1] = temp;
                    printf("DEBUG: Do i move trough here?");
                    return true;
                }
            }
            if (row < d-1) //makes sure C does not acces any space underneath 2D-array
            {
                if (board[row+1][column+0] == 0) // checks if blank space is underneath tile 
                {
                    temp = tile;     //switch the tiles
                    board[row][column] = board[row+1][column+0];
                    board[row+1][column+0] = temp;
                    return true;
                }
            }
        }
    }
}
return false;

Answer 1

Well, I don't know how to tell you this, but I plugged your move function into my code and it worked perfectly. I suspect that you have a problem elsewhere in your code. Have you altered something in main that you shouldn't have? Is it possible that you are reinitializing the board after every move so that it just appears that you aren't making the move? When you wrote draw(), you wrote it using the current positions of each tile and not the initial positions, right? (This is where I'm betting the problem lies, since the board is redrawn after each move.) And you're also storing the results of the swap, right?
