Hi.
Sorry for the delay.
Here is a sample.
Don't be scared about the amount of code.
My idea here is to try to create a generalist and reusable drag and drop game component and also a timer component.
If you'not comfortable with external custom classes and OOP techiniques, try to at least understand how to use the classes inside of the FLA. You'll see it's not that hard.
AS3 code:
[FLA]
[Frame 1]
import flash.display.DisplayObject;
var game:DragAndDropGame;
var timer:CustomTimer;
function start():void
{
stop();
game = new DragAndDropGame(pieces, slots, true, onMatch, onMismatch);
timer = new CustomTimer(15, timerText, null, onTimeFinished);
timer.start();
}
function onMatch(target:DisplayObject):void
{
trace("Correct!");
gotoAndStop("correct");
}
function onMismatch(target:DisplayObject):void
{
trace("Incorrect...");
gotoAndStop("incorrect");
}
function onTimeFinished(target:CustomTimer):void
{
trace("Time is out!");
gotoAndStop("timeout");
}
start();
[Frame 2]
timer.stop();
[Frame 3]
timer.start(10);
You only need to understand up until here.

I hope this helps.
