too bad you version requies all slots to be full. something very unlikely in the in most applications. a little update would be very appreiated for those struggling to use your version

I’ve found a bug in this class in function getPosition
Here’s the correct version:(Sorry if there is any code format inconvenience.)
private function getPosition(row : int, col : int) : Point
{
return new Point(col * (_rowSize + _padd), row * (_colSize + _padd));
}

Excellent post with the drag & drop shuffle grid menu systems. I really love it & inspired with this AS3 shuffle grid class.

Thx for sharing such an informative post with appropriate coding

amazing work!
Excuse me for the stupid question, but I try figure out how can I get an items by its position on the grid. For example to call item at 1-st cell, or second, or items by its col and raw position. Please help!

Hi,

I couldn’t quite get Sabee’s exact code to work but the following is working for me for grids that are not full

change these two functions:

public function getItemAtPosition(row : int, col : int) : ShuffleGridItemVO
{
var item:ShuffleGridItemVO;

if(_index[row] != null && _index[row].length > col)
{
item = _index[row][col];
}else
{
item = null;
}
return item;
}

and

private function shuffleItems() : void
{
var itemVO : ShuffleGridItemVO = _dictionary[_currentItem];
var cell : Point = getCell(_currentItem.x, _currentItem.y);

var col : int = (getItemAtPosition(cell.y, cell.x) != null)?cell.x: itemVO.col;
var row : int = (getItemAtPosition(cell.y, cell.x) != null)?cell.y: itemVO.row;

var colFound:Boolean = false;

if(col == itemVO.col && row == itemVO.row)
{
return;
}

var hMove : int = (col == itemVO.col)?0:col – itemVO.col;
var vMove : int = (row == itemVO.row)?0:row – itemVO.row;

var i : int;
var item : ShuffleGridItemVO;
var move : Array = [];

if(hMove = itemVO.col + hMove; i–)
{
if(_index[itemVO.row][i])
{
item = _index[itemVO.row][i];
item.col++;

_index[item.row][item.col] = item;
move.push(item);
}
}
}
else
{
for (i = itemVO.col + 1;i <= itemVO.col + hMove; i++)
{
if(_index[itemVO.row][i])
{
item = _index[itemVO.row][i];
item.col–;

_index[item.row][item.col] = item;
move.push(item);
}
}
}

if(vMove = itemVO.row + vMove; i–)
{
if(_index[i][itemVO.col + hMove])
{
item = _index[i][itemVO.col + hMove];
item.row++;

while(!colFound){
if (getItemAtPosition(item.row, item.col)) {
colFound = true;
}else {
item.col–;
}
}

_index[item.row][item.col] = item;
move.push(item);

}
}
}
else
{
for (i = itemVO.row + 1;i <= itemVO.row + vMove; i++)
{
if(_index[i][itemVO.col + hMove])
{
item = _index[i][itemVO.col + hMove];
item.row–;

_index[item.row][item.col] = item;
move.push(item);
}
}
}

for (i = 0;i < move.length; i++)
{
snapToGrid(move[i]);
}

itemVO.row = row;
itemVO.col = col;

_index[row][col] = itemVO;
}

Hi Soulwire,

Thank you so much for sharing this! Sabee posted some code for irregular grids but it seems to have some bits missing. Did you ever find time to figure this out?

Cheers
Rich
