How to restart an SWF with a click of a button? - actionscript-3

Question

I have created a drag and drop mini-game and, once finished, I wish for the user to be able to click a "try again" button and have the whole thing start over.
I have read in to this and see that there are a couple of options but am stuck as to which would be best for me.
I have created an FLA with all of my library items, an AS file (MainGame.as) with the main game and all of it's functions in one class and a second AS file (MyGame.as) which calls the class file to play the game.
Which would work best for me?
I have nothing on the layers and just cannot figure out how to remove the swf and load it again with the click of a button.
Am I right in thinking that I would add the button to the MyGame file in the timerDone function?
If so, how would I use that to reload the SWF from the start?
Here is my timerDone function ...
function timerDone(e:TimerEvent=null):void
{
if (countDown == 0)
{
count = 0;
finalScore = score;
}
else
{
count = (30) - (myTimer.currentCount);
finalScore = (count * 10) + (score);
}
myText.text = "GAME OVER!";
myText.x = 195;
displayText();
myText2.text = "Your score = " + (finalScore);
displayText2();
}
I am thinking that I add the button after the last line and somehow refresh the SWF, is that right?
Or am I way off?

Answer 1

You should do something like that: you call the function toReplay at the end of your function timerDone:
Function timerDone, after "displayText2();"
tryAgain.addEventListener(MouseEvent.CLICK, toReplay);
Outside the function timerDone
/**
* The function toReplay calls the function init which
* initializes the Timer and all your variables.
**/
function toReplay(e:MouseEvent):void {
e.target.removeEventListener(MouseEvent.CLICK, toReplay);
init();
}
function init():void {
// Timer
count = 0;
finalScore = 0;
myText.text = "";
// etc.
}
And the function init can directly be invoked to initialize all your variables at the begining of the game:
init();
