Lottery ticket scratcher effect in AS3

Here is a really sharp ActionScript 3 class that creates a quick way to make a fun promotional or interactive scratch off effect.

Much like the rub off effect used on lottery tickets and sweepstakes, with this class you can add in your image and then have your website visitors interact with the page to reveal the hidden message, image, video, link, or promotion that is underneath.

Oh, did we mention it was free? Thanks to our pals at it is!

Here is the simple to understand source code:

// immortalwolf scratch off
package com.immortalwolf{
import flash.display.Sprite;
import flash.display.MovieClip;
import flash.ui.Mouse;

public class ScratchOff extends MovieClip{
var scratcherIsActive:Boolean= false;
var stuffUnderMask:Sprite = new Sprite();

// init class
public function ScratchOff():void{
stage.addEventListener(MouseEvent.MOUSE_DOWN, mouseIsDown);
stage.addEventListener(MouseEvent.MOUSE_MOVE, mouseIsMoving);
stage.addEventListener(MouseEvent.MOUSE_UP, mouseIsUp);
// make mask
stuffUnderMaskClip.mask = stuffUnderMask;

// helper functions
private function makeCursor():void{
trace("you can make a special cursor and hide it!");
// hover effects
private function mouseIsDown(e:MouseEvent):void{
scratcherIsActive = true;
private function mouseIsUp(e:MouseEvent):void{
scratcherIsActive = false;
private function mouseIsMoving(e:MouseEvent):void{
if(scratcherIsActive){;, mouseY,40, 40);;
}// class
}// package

Pretty straightforward huh? But fun also!

The shape of the element getting scratched off doesn’t have to be a circle by the way – so get creative!
