AS3 Code problem

[gibsy]

I wrote this code:

match = new Array();

matchHoriz = new Array();

row = 0;

while (row < gridRows)

{

      col = 0;

     while (col < gridCols)

     {

          match = getHorizMatch (row, col);

          if (match.length > 1)

          {

               match.unshift(grid[row][col]);

               matchHoriz.push(match);

              // ***1        

          }

          if (match.length == 0)

          {

               col++;

          }

          else

          {

               col = col + match.length;

          }

          match.length = 0;

     }

     row ++;

}

// ***2

If I place trace(matchHoriz) on position // ***1 it shows the correct result (an array with matched objects).

If I place trace(matchHoriz) on position // ***2 it doesn't show anything.

What is wrong about my code???

[kglad]

are you improperly setting a while-limit and not completing those loops?

[gibsy]

The code is finishing as it should be. The while loop finishes, but somewhere the matchHoriz array is losing it's values.

[kglad]

then check getHorizMatch() for any matchHoriz maniuplation

When you clear match, you clear the references to it that you've pushed into matchHoriz.

[gibsy]

Before I clear the match array, the array is added to the array matchHoriz so the data should be there no matter what I do with match array data. I figured out what was happening: when I add the match array with push, the data in the matchHoriz array doesn't look as I expected. I changed push with concat and everything is going right now.

Thanks.

Correct, when you change to concat, you're no longer putting in a reference to the match array. Instead, you're copying its contents, which is what you apparently thought you were doing before .
