Use this format for submitting snippets It may be used later to parse the snippets to a application (like the one in the VB Section) If you're going to post a snippet in this thread then you should be posting it in the following format: Snippet Name: ____________________ Keywords: ____,____,____ ... Description(Optional): _______________________ Code: Your Code Here... This is to be used for any small bit of code you would like to share.

Snippet Name: Shuffle Array (Action Script 3)
Keywords: Flash,Shuffle,Array,AS3
Description: This reorders the elements of an array into a random order.

Code:

var anArray:Array = [1,1,1,1,1,1,2,2,2,2,2,2,3,3,3,3,3,3,4,4,4,4,4];
anArray=shuffleArray(anArray);

function shuffleArray(arr:Array):Array{
 var arr2:Array = [];
 while (arr.length > 0){
  arr2.push(gendersArray.splice(Math . round(Math.random() * (arr.length - 1)), 1)[0]);
 }
 return arr2;
}

Snippet Name: Convert a String into an Array Using Action Script 3
Keywords: String To Array, AS3
Description: Converts the string into an array using the actionscript "split" function.

Code:

//the string to turn into an array
var arrayString:String="1,2,3"; 
//convert the string to an array using the "," as a divider (aka delimiter)
var newArray:Array= arrayString.split(",")  
//convert the array items from strings to numbers
var n=newArray.length;
 while (n--) {
  newArray[n]=Number(newArray[n])
 }
trace(String(trainCubesArray[0]+1));

Snippet Name: Detecting when mouse leaves stage.
Keywords: Mouse Detection, AS, Flash, Rollover, Hover
Description: This is how you detect if the mouse leaves Flash and rolls over to web page:

Code:

var c:Sprite = new Sprite();
c.graphics.beginFill(0xFF);
c.graphics.drawRect(0, 0, 200, 200);
addChild(c);
stage.addEventListener(Event.MOUSE_LEAVE, cursorHide);
//there is no mouse exit so you need to use this
stage.addEventListener(MouseEvent.MOUSE_MOVE, cursorFollow);
function cursorHide(evt:Event):void {
 c.alpha=.2
}
function cursorFollow(evt:MouseEvent):void {
 c.alpha=1
 evt.updateAfterEvent();
}

Snippet Name:Blur Using AS3
Keywords: Blur,Flash,AS3,AS4
Description:Creates a blur effect on movie clips.

Code:

var blur:BlurFilter = new BlurFilter();
blur.blurX=20;
blur.blurY=20;
blur.quality=BitmapFilterQuality.LOW;
displayObjectToBlur_mc.filters=[blur];

Snippet Name:AS3 full screen mode
Keywords: AS3, FullScreen, Mode
Description:Toggles full screen mode using AS3.

Code:

function toggleFullScreenMode(e:MouseEvent):void {
 if (viewingFullScreen==false) {
  viewingFullScreen=true;
  navsNorthMultiPage_mc.tween_mc.eastButtons_mc.fullScreenAnim_mc.gotoAndPlay("full");
  navsSouthMultiPage_mc.tween_mc.eastButtons_mc.fullScreenAnim_mc.gotoAndPlay("full");
  stage.displayState="fullScreen";
 } else {
  viewingFullScreen=false;
  navsNorthMultiPage_mc.tween_mc.eastButtons_mc.fullScreenAnim_mc.gotoAndPlay("out");
  navsSouthMultiPage_mc.tween_mc.eastButtons_mc.fullScreenAnim_mc.gotoAndPlay("out");
  stage.displayState="normal";
 }
}

Snippet Name:AS3 Disable Yellow Tab Rectangles
Keywords:Disable, AS3, Tab, Rectangles
Description:Are you wondering why when you hit tab in your Flash site you get those nasty yellow rectangles around your links? Here's how to disable them:

If you have a movieclip with a bunch of buttons inside it and you want to disable all of them with one line of code use this:

Code:

MC_Container_Name.tabChildren = false;

Or to just disable the yellow box on a single movieclip use this:

Code:

MC_Name.tabEnabled = false;

Snippet Name:AS3 Smooth Loaded Bitmaps
Keywords:AS3,Smooth,Loaded,Bitmaps
Description: Loaded bitmaps (jpgs, pngs, etc) look bad in flash when scaling unless you smooth them. This function seems to replicate the bitmap "smoothng" setting in the library pallette. I still see tons of Flash sites out there that arent aware of this awesome setting. It makes bitmaps look great when they scale.

Code:

//create a new loader object and put it on the stage
var slideLoader:Loader=new Loader();
this.addChild(slideLoader);

//load picture into loader object
slideLoader.contentLoaderInfo.addEventListener(Even*****MPLETE, scaleContentForPicture);
slideLoader.load(new URLRequest("http://www.mpgh.net/forum/images/tree.jpg"));

//smooth it once loaded
function scaleContentForPicture() {
var smoother_bm=Bitmap(slideLoader.content);
smoother_bm.smoothing=true;
}

Snippet Name:Slideshow with autoplay and reset delay
Keywords:AS3,Slideshow,autoplay
Description: This code starts with a long pause then starts looping through images. If the user interacts with the slideshow, the timer is reset then starts playing again later if the user hasnt interacted.

Code:

var resetTime:uint=5000;
var pauseBetweenSlides:uint=5000;
var slideCounter:uint=1;
var prevSlide:uint=0;

var startShowTimer:Timer=new Timer(resetTime,1);
startShowTimer.addEventListener(TimerEvent.TIMER, setUpTimer);
var slideShowTimer:Timer=new Timer(pauseBetweenSlides,0);
slideShowTimer.addEventListener(TimerEvent.TIMER, autoAdvance);

//auto advance
function autoAdvance(e:TimerEvent):void {
 nexttSlide();
}

//next
function nexttSlide():void {
 prevSlide=slideCounter;
 slideCounter++;
 if (slideCounter==6) {
  slideCounter=1;
 }
 goToSlide();
}
//prev
function prevvSlide():void {
 prevSlide=slideCounter;
 slideCounter--;
 if (slideCounter==0) {
  slideCounter=5;
 }
 goToSlide();
}
//display next slide and hide previous
function goToSlide():void {
 slideshow_mc["slide"+slideCounter+"_mc"].gotoAndPlay("show");
 if (prevSlide>0) {
  slideshow_mc["slide"+prevSlide+"_mc"].gotoAndPlay("hide");
 }
}
//pause slideshow and reset timer
function resetTimer():void {
 slideShowTimer.stop();
 startShowTimer.reset();
 startShowTimer.start();
}
//called when reset pause is finished
function setUpTimer(e:TimerEvent):void {
 startShowTimer.reset();
 slideShowTimer.start();
}


resetTimer();
goToSlide();


//Controls--------
function showControls():void {
 slideShowPrev_mc.gotoAndPlay("show");
 slideShowNext_mc.gotoAndPlay("show");
}
function hideControls():void {
 slideShowPrev_mc.gotoAndPlay("hide");
 slideShowNext_mc.gotoAndPlay("hide");
}



slideShowNext_mc.addEventListener(MouseEvent.CLICK, invokeNextSlide);
function invokeNextSlide(e:MouseEvent):void {
 resetTimer();
 nexttSlide();
}
slideShowPrev_mc.addEventListener(MouseEvent.CLICK, invokePrevSlide);
function invokePrevSlide(e:MouseEvent):void {
 resetTimer();
 prevvSlide();
}
