as3 restting my game

[learningas3]

i'm having a bit of trouble figuring how to reset my game. i have a button that will reset when clicked. anyone have any clue what i should do here?

{
import flash.display.Sprite;
import flash.events.Event;
import flash.events.MouseEvent;

[SWF(width="800", height="600", backgroundColor="#E6FCFF")] // changing the width, height and bg color of the page

public class Main extends Sprite
{
// creating properties
private var _sittingDucks:Array = []; //always set your arrays with [] at the top
public var board:ScoreDisplay;
private var _waves:WaveBase;

public function Main()
{
// adding the background, and positioning it
var background:Background = new Background(); // instantiating
this.addChild(background); // addChild() adds to display list
background.x = 30; // positiioning left or right
background.y = 100; // positioning up or down

for(var i:uint = 0; i < 5; i++) // creates 5 clouds
{
//adding the first cloud, and positioning it
var clouds:Clouds = new Clouds(); // instantiating
this.addChild(clouds);// addChild() adds to display list
clouds.x = 130 + Math.random() * 600; //130 to 730
clouds.y = 230; // positioning 230px
clouds.speedX = Math.random() * 3; // adding random speeds between each cloud
clouds.width = clouds.height = 200 * Math.random()//randomly changes the clouds demensions
}
//adding the first cloud, and positioning it
var _waves:Waves = new Waves(); // instantiating
this.addChild(_waves);// addChild() adds to display list
_waves.x = 0;// positioning 0px
_waves.y = 510;// positioning 510px
_waves.speedX = Math.random() * 3;// adding random speeds between the background wave

for(var j:uint = 0; j < 8; j++)// creates 8 ducks
{
var ducksucks = new Ducks();// instantiating
this.addChild(ducks);// addChild() adds to display list
ducks.x = 100 + j * 100;// positioning at 100px plus, spacing out the ducks at 100px
ducks.y = 475;// positioning 475px
_sittingDucks.push(ducks); //adding the ducks to the array
//object.addEventListener(Event.TYPE, Function);
ducks.addEventListener(MouseEvent.CLICK, ducksDestroy); // event which triggers the click function
}
//i tried adding the waves as a forloop like the clouds and ducks, but it never came out right, idk why?
var _waves2:Waves = new Waves();// instantiating
this.addChild(_waves2);// addChild() adds to display list
_waves2.x = 0;// positioning at 0px
_waves2.y = 520;// positioning at 520px
_waves2.speedX = Math.random() * 3;// adding random speeds between the foreground wave

var setting:ForeGround = new ForeGround();// instantiating
this.addChild(setting);// addChild() adds to display list
setting.x = 0;// positioning at 0px
setting.y = 50;// positioning at 50px
setting.width = 920;// setting the width of the curtains at 920px. it wasn't right as default

board = new ScoreDisplay();// instantiating
this.addChild(board);// addChild() adds to display list
board.x = 570;// positioning at 570px
board.y = 35;// positioning at 35px
board.scoreUpdate(8) //this displays the number of ducks from the start

}

private function ducksDestroy(event:MouseEvent):void
{
//store the ducks we clicked on in a new array
var clickedDuckucks = Ducks(event.currentTarget);

//remove it from the ducks array
//find the address of the ducks we are removing
var index:uint = _sittingDucks.indexOf(clickedDuck);

//remove it from the array with splice
_sittingDucks.splice(index, 1);

//remove it from my document's display list
this.removeChild(clickedDuck);

board.scoreUpdate(_sittingDucks.length);
//update the score

//Check if all the ducks are gone
if (_sittingDucks.length == 0) //meaning, if the amount of ducks is zero, do the code below
{
//showing the you win sign after all the ducks are gone
var win:YouWonSignBase = new YouWonSignBase();// instantiating
this.addChild(win);// addChild() adds to display list
win.x = 380;// positioning at 380px
win.y = 300;// positioning at 300px

}
}
}
}

ok - so here, your setting up almost everything within the constructor - this is fine, but it's times like this where you run into issues - it would be better if you were to create a method that instantiates the game scene using basically everything you have in 'Main', then you can call it to 'build' the scene - so you would call it initially in the constructor, then on game over you remove everything from the stage, and call the method again which will reset all of the data

another approach is to separate the 'ducks' layer, and since nothing else 'changes' in the game, instead of removing everything and replacing it with new, simply put more ducks on the 'duck layer' and reset the score property - so you would separate the loop for the ducks into a method that does this, then instantiate a container instance (like Sprite) at the correct depth between the waves, then you'll be adding the ducks to that container/layer, as opposed to the stage
