AS3 Code problem

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???

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 .

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

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.
