    <p>Personally, I would have an array/Vector (Vectors are much, much faster. Though they can be a royal pain to use) of objects within each individual zone. You keep this updated at all times. If you remove one, you use <code>splice(indexOf(obj),1)</code> to remove it from the array.</p> <p>For your problem, I would do this:</p> <pre><code>var p1:Sprite = new Sprite(); var p2:Sprite = new Sprite(); var zoneArray:Array = new Array();//there would be one for each zone, simplified it here //this code would run whenever an object enters the zone function zoneEnter(e:Event = null):void{ var currentZone:Sprite; //set this equal to the zone the sprite just entered var currentObject:Sprite = e.currentTarget as Sprite; //this way we know which object just entered currentZone if ( currentObject == p1 &amp;&amp; zoneArray.indexOf(p2) &gt;= 0 ) { //prevent it from entering the zone } if ( currentObject == p2 &amp;&amp; zoneArray.indexOf(p1) &gt;= 0 ) { //prevent it from entering the zone } } </code></pre> <p>There are obviously some limitations here if you are looking at a lot of objects. But if you know, for sure, there will only be two, I think this would be the way to go. If there will be more, you would need to create some kind of control structure that would allow you to check an object against other objects. I could elaborate and give a sample of what I am talking of here if it's needed. It's a tad bit complex, but not hard to implement.</p> <p>EDIT 10-17-12: Added in example code of how the more advanced logic would look.</p> <pre><code>var puzzleMap:Array = new Array(); var piece1:Piece = new Piece(); //this is the puzzle piece we'll be checking var piece2:Piece = new Piece(); var piece3:Piece = new Piece(); var piece1Objs:Array = [piece2,piece3]; var piece2Objs:Array = [piece1,piece3]; puzzleMap.push({piece:piece1,others:piece1Objs}); puzzleMap.push({piece:piece2,others:puzzle2Objs); private function stopDragHandler(e:MouseEvent = null):void{ var space:Space = space; //this is the space the object was dropped into (I don't know how you identify them, so this is pseudo code) var valid:Boolean = true; //we'll check for a bad drop since it's easiest if (event.target.dropTarget != null &amp;&amp; MovieClip(event.target.dropTarget.parent).allowed.indexOf(event.target) &gt; -1){ for ( var i:Number = 0; i &lt; puzzleMap.length; i++ ) { var current:Object = puzzleMap[i]; if ( current == e.currentTarget ) { for ( var j:Number = 0; j &lt; current.others.length; j++ ) { var checkAgainst:Piece = current.others[i] as Piece; if ( space.currentObjects.indexOf(checkAgainst) &lt; 0 ) { valid = false; break; } } } } if ( !valid ) { //prevent the drop here } } } </code></pre>

    1. COYes, in total, there will be 4 puzzle pieces (2 pairs of duplicates). A sample would be ideal. I'm also curious to know how I would add that function into my existing if statement for stopDrag: "if (event.target.dropTarget != null && MovieClip(event.target.dropTarget.parent).allowed.indexOf(event.target) > -1){ etc....

    2. CO@habib_101 I just edited my answer to include the code. It's a bit more advanced than I think you need (my previously posted code or the code provided by Dave Hart will work just fine), but it should do what would be needed. I would highly suggest having different classes for your Pieces and Spaces so that you could nest some of this in there. Ideally, the piece1Objs object and space.currentObjects would be objects/arrays within the class. Again, this is overkill for you. If you were to try to expand your project, though, this might be useful

    3. COI just tried the code by am getting an error 1046 "Type was not found..." on these lines: var piece1:Piece = new Piece(); //this is the puzzle piece we'll be checking var piece2:Piece = new Piece(); var piece3:Piece = new Piece();

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
