   Hey Soulwire , This site is awesome and you show a great programming stuff!! I can see a Pattern based oops in it..

   nJoy Coding!!

   To drewm ,

   It is not a bug, it does what he programmed… When you click and drag quickly, you may not know where your mouse pointer is.. If the mouse pointer is not pointing the SWF window, obviously the “Tile will be dropped”

   Thank you very much for your script!
   I’ve made a adjustment for the grid to work irregulary. It’s probably not the best optimized but works perfect for me and could work for others.

   Here is what I do:

   1) I declare an empty grid at start:
   this.grid = new ShuffleGrid(0, 0, ThumbGiftZone.WIDTH, ThumbGiftZone.HEIGHT, paddingGrid);
   addChild(grid)

   2) I add (in a loop or not) items to the grid with:

   var maxCols:uint = Math.floor(stage.stageWidth / (ThumbGiftZone.WIDTH + padding));
   grid.updateIndexArray(1, maxCols);

   var thumb:ThumbGiftZone = new ThumbGiftZone();
   grid.addItem(thumb);

   You can see I added a new function inside ShuffleGrid.as, here it is:

   public function updateIndexArray(numToAdd:int, maxCols:int):void
   		{
   			var tempNumItems:uint = numItems + numToAdd;
   			var i:int;
   			var j:int;
   			var cols:int;
   			var dif:int;
   
   			var rows:int = Math.ceil(tempNumItems / maxCols);
   
   			for (i = 0; i < rows; i++)
   			{
   				if(_index.length < rows)
   				{
   					_index.push(new Array());
   				}
   
   				// Pour chaque row on détermine le nombre de col. Tous sauf la dernière auront le maxCols
   				cols = (i < rows-1)?maxCols:tempNumItems - (i * maxCols);
   
   				if(_index[i].length < cols)
   				{
   					dif = cols - _index[i].length;
   					for (j = 0; j  1)?maxCols:cols;
   		}
   

   Then I did chane shuffelItems:

   private function shuffleItems() : void
   		{
   			var itemVO : ShuffleGridItemVO = _dictionary[_currentItem];
   			var cell : Point = getCell(_currentItem.x, _currentItem.y);
   
   			var col : int = cell.x;
   			var row : int = (getItemAtPosition(cell.y, cell.x) != null)?cell.y: itemVO.row;
   
   			if(col == itemVO.col && row == itemVO.row)
   			{
   				return;
   			}
   
   			var hMove : int = 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++;
   
   						if(item.col >= _index[item.row].length)
   						{
   							item.col = _index[item.row].length - 1;
   						}
   
   						_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  col)
   			{
   				itemVO.col = col;
   			}
   
   			_index[row][itemVO.col] = itemVO;
   		}
   

   AND getItemAtPosition

   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;
   		}
   

   The whole idea I use is that, even though there is a grid of 6 x 2 for example, if there no “thumb” at row 2, col 3 then I don’t allow the move and don’t update the v move during the shuffleItems()
