Please help convert from as2

Question

I never learnt as2 and I just purchased a fla file from a stock sight thinking it was in as3 and it isn't!!! doh
can anyone help me convert this from as2 to as3:
stop();
import flash.filters.*;
//--------------variables to change--------------------------//
//set this value to true if you want sparkles to be created from the mouse
//and false if you want automatic sparkles
var createSparklesFromAnyMouse:Boolean = true;
//set to true if you want sparkles to stop being created when the mouse
//is still
var createSparklesFromClick:Boolean = false;
//modify the size of the sparkles
var maxSparkSize:Number = 18;
var minSparkSize:Number = 8;
//increase this value to shorten the life, 0 to live forever
var fadeSpeed:Number = 10;
//the speed the sparkles fall, higher number quicker the speed
var speed:Number = 1;
//choose whether you want the sparkle colour to be random
var randomColour:Boolean = true;
//if you don't want a random colour pick a default colour
defaultColour = 0xFFffFF;
//do not modify code below here...
var sparkle:Number = 0;
var mousePosX:Number;
var mousePosY:Number;
var whichBat:Number;
var count:Number = 0;

Zhanbolat,
In theory, conversion of this code is not difficult, especially because it is clear what the logic is designed to do. The issue is that you will not have an expected result once only this code is converted in isolation. This puppy uses some other objects that are written in AS2 including entities in the FLA library.
In short, it looks like this application needs a total overhaul at every level in order for it to properly function as an AS3 program.
With that said, although this is, again, not a difficult task, it is unlikely to find someone to do it for free. You may have a better luck if you start conversion yourself and post focused questions as you go.
