as3 droptarget

I'm doing a drag and drop interaction.  The very basic code is

function mouseDown(event:MouseEvent):void
{
	event.currentTarget.startDrag();
}


function mouseReleased(event:MouseEvent):void
{
	event.currentTarget.stopDrag();
	if (event.currentTarget.dropTarget != null)
	{		
		event.currentTarget.x = event.currentTarget.dropTarget.parent.x;
		event.currentTarget.y = event.currentTarget.dropTarget.parent.y;
	}	
}

Open in new window


I'll have several draggable objects and droptargets.  Now the problem I have is if a given droptarget already has something dropped on it, it shouldn't allow anything else to be dropped on it ie. "disabled".  If I drag the object off of it, that particular target would need to be "enabled" again.  Haven't come up with any idea on how to do this.

Oh yeah, all the draggable objects are able to be dropped on all of the droptargets.  I'll evaluate whether the correct objects have been dropped on the correct targets later.

If you are using DragManager class

http://livedocs.adobe.com/livecycle/8.2/programLC/common/langref/mx/managers/DragManager.html

You should control all your drop target(s) by acceptDragDrop API

Not using Flex or any ui components.  The draggable objects and droptargets are just movieclips.

But DragManager is not for Flex is ActionScript 3 class.

Check this example its pure AS

Why not simply add a flag to the drop target that says there is something dropped in it? MovieClips are dynamic; you can create a new field and check to see if it exists and is set in your MouseDown event.
