ActionScript 3.0 :: Implementing Invisible Buttons - Optimizing Performance
Feb 6, 2009
I know of a couple of methods of implementing an invisible button or "hotspot" or clickable area:
1) Draw a fill region on a Sprite with an alpha of 0.
2) Create a Button with only a hitArea
Which method would be less resource intensive? Since Adobe recommends against using too much alpaha, I image (2) is better. Are there other methods which could be even less resource intensive? In the movie I am doing, there will be many of these on the screen so optimziing for performance is important.

We have a medium size Flex 3.6 application that contains around 20 different page views (managed via a single lazy ViewStack) each having multiple components. Most use custom renderers.All model data is loaded at startup and changes to model instances are communicated via binding and/or collection change events.Once the user has viewed each page at least once, all page views are instantiated and happily listen to update events.Which in effect means that each time a model instance changes, all interested views receive that event and compute derived data or trigger item-renderers.I have tested and confirmed this behaviour in a proof-of-concept application. Even when setting a list to being invisible, it still listens to collection change events and invalidates any renderer affected.What would you do?

Well, attempting to optimize scrollBar performance I've discovered that some event won't dispatch - I went all though that's even life with debugger, and, at some point it was like this:
Code:
private const _scrollEvent:ScrollEvent = new ScrollEvent(ScrollEvent.SCROLL);
public override function set scrollRect(value:Rectangle):void {
super.scrollRect = value;
trace(super.hasEventListener(ScrollEvent.SCROLL)); // true
super.dispatchEvent(this._scrollEvent);
I never call myself nothing like stopPropagation() or stopImmediatePropagation(), in fact, I don't really care about the event itself, for me it may be null - I don't need the contents of the event at all, but the scrollHandler() in such situation isn't getting called... In .NET events commonly have property "Handled" this property is there to tell whether the event was already processed by a handler or not. However, you, as a developer have control over it - you may decide whether to process it further or not, but it seems like in AS3 you must bloat the player's memory with piles of useless clones of same event...

I have created 3 invisible buttons over a graphic. Each has its own button layer and action layer. For each action layer I have used:
my_button1.addEventListener(MouseEvent.CLICK,clickHandler1);
function clickHandler1(event:MouseEvent):void{

When I test the movie I see the hand icon so I know it's an invisible button, but when I click on it, it goes out of the flash play like it wants to go to a browser, but nothing happens. When I upload the files I can see the hand icon again, but nothing happens when I click on the link. I tried the changing the .html file that it is housed in to an .htm file, but that didn't work either.

I've got a few HBoxes with buttons in them. I programmatically make certain buttons invisible. At a certain point, all of the buttons should be invisible. How can I tell when all of the buttons are invisible? What's the easiest way of doing so?

I have a 2 frame flash movie where the first has a group of names that are clickable hidden by actionscript. You need to click directors, then the names come up and then click the name to go to the 2nd frame of the move which brings in their information dynamically. This has a close button that takes you back to the first frame. My problem is that when going back to the first frame after closing the CV data, it still shows the area where those names were listed as clickable even though they aren't visible.
The code on frame 1 that I think is relative is below. The movie clip that houses the clickable name list is called bodBorderMC and it's loading the directors so I'm not sure if directors in the code works with that.

I don't know if it's an AS3 thing, or a Flash 10 thing, both of which I don't work in frequently..... (usually, I'm working in Flash 8, and AS2 for most of my projects)
Basically, when I have invisible content over a button in my flash movie, the button no longer works. Like I said, it's something that's never been an issue before.
Where it shows up is when I want to make a piece of content visible over a button when the user mouses over the button, so the piece of content would start over the button with its alpha set to 0. I would typically change the visibility of the object I want to make visible when the button is rolled over. But now when that object is over my button at 0 opacity, the button no longer works....and again, I've never had this be an issue before.

I'm somewhat stuck in a project that I have to deliver next Friday. Thing is... I've got to code a webpage like The Killers Band webpage with a panoramic picture moving according to your mouse movements.
I've tried several things already, but I had no success yet. (Everything must be coded in AS2.0, and I'm using Flash CS3 to cover the project).
All I have is the panoramic picture, which I might be able to upload if you ask me to.
Additional info:
I've already converted the background picture into a movie clip symbol. Also, if I ever have to send the picture to anyone, I'll send it as a Private Message, since I can't post links yet.

scrolling = function () {
var scrollHeight:Number = scrollTrack._height;

I need to show different custom pointer when mouseover 2 different invisible buttons. These are next and back buttons which cover the entire left and right part of the stage. How this can be done in as3? Or is there a better way of doing it? I checked out the import flash.ui adobe live doc but can't quite make head and tail of it. I guess the example shown is only to change to custom cursor for entire stage.

I keep hearing about using a big invisible button on the top layer of your flash movie when you want any click to take you to another website for example. But what Ive done is a little different. My very BOTTOM layer is a background gradient, which is obviously not invisible. In my actionscript I have Gradient.onRelease = function () {getURL... etc etc This seems to work on my computer. The question is, is this a bad practice? Will this fail on some versions of flash players/browsers? Is the invisible button method better? It just seems dumb to do the invisible button thing when i have a perfectly sized background gradient that seems to work.

I thought I had a good hold on how to create buttons from a class, but my invis class will not return the button that is created to my fla. I have been able to access functions of invis class from my fla, even instantiate the object, but none of the button states carry over to the fla. If you can help I'd appreciate it. I placed the code below.
invis class
Code:
package {
import flash.display.SimpleButton;
import flash.display.Shape;
[code]...
The trace seen in the button fla return null, somehow none of the states are applied to the object.

I have some movie clips turned buttons (by way of mc.buttonMode = true and friends) that scroll by an invisible button area, and when they are 'under' that area, none of their mouse events work. How can I still catch their mouse events in addition to the MOUSE_OVER of the invisible button on top?

this is what i'm trying to accomplish; With a click on a movieclip (cannon_mc)a shot is being fired (ball_mc)
The longer mouse is down, the speed of wich the ball is fired with should increase.My question to you is;
What is the most efficient way to accomplish this? With a timer or something like this;

I'm devloping some library classes for flocking/steering behaviours on large numbers of objects (2000+). I'm finding that at < 500 instances, performance is reasonable. As the numbers increase, framerate bogs down.
I've seen remarkable performance with libraries such as Flint or Box2D with ridiculous #'s of particles / objects, so it should be possible to optimize / refactor my code to be a bit better.
I'm aware of the basic optimizations, such as bitwise operations and optimized for loops. Are there any more fundamental approaches I should be considering? For example, currently each instance is a vector-based MovieClip. Would working with BitmapData be more efficient?

Will I take a big hit in performance using nested ViewStacks? Should I strive to handle all navigation in one ViewStack and push children manually or will the affected performance be negligible?
eg.

Is it possible to create a invisible mc with in 2 other invisible mc's and if so would there be any complications. Im trying to do something similar and it gets to the second layer but then doesnt want to load the third inv-mc. Like loading an external swf to a container mc then in that same mc have another external load and then another.

I have an as3 app which utilises an sqlite db to save metrics data. It is well known that as3 is single threaded, so when I save to this db, the Stage Video I am playing becomes jumpy! I have heard that saving db data in batches can speed up this process so I save in a loop:
for (var i:int=0; i < metricsObject.metricsComponentData.length; i++){
switch (metricsObject.metricsComponentData[i].mouseType) {
case MetricsCollator.MOUSE_OVER:
this._query_txt = "INSERT INTO " + this._tablePath[0] + " VALUES (null, " + this._sessionID +
[code]...
I have looked into pseudo threading examples but they all require a sprite or stage instance, the class I am executing this code in, is not a display class, I don't really want to pass an instance of the stage into this class.

It seems to me everytime I export a PSD design into flash the images come out a little pixelated. Granted I do use 72 dpi though I thought that was the webstandard. By using flash can I use higher dpi images? Or is there another method I should be using instead of the direct import to lirbary?

Some AS operations are more CPU intensive than others. What are good ways to compare operations so that I can see for myself how demanding something is? Are there built-in AS3 methods for tracing system use or CPU use? Are there non-flash tools that people use?

I have created a X-mas card for my company. When the card opens, the 3 circles are buttons to different scenes within Flash. The text in the bottom left is a button to the final scene.
The card can be viewed here: [URL]
1) When I click on the circle button that has the red garland and tree ornaments in it, if you listen close at the very beginning of the scene, a squeek sound plays. I use this squek sound in the hamster wheel movie symbol used in other scenes, but not in this scene. I don't even have the sound in this scene of the Flash project anywhere. I can not figure out where it is coming from.
2) Does anyone have some optimization tips? My project file is huge and a lot of the people we will be sending this out to probably don't have the most up-to-date processers. Should I split each scene into it's own Flash movie that is only loaded when the button for that scene is selected instead of the whole thing loading?
Here is a link to view the .FLA file: [URL]

I'm working on a flash website that consists of 3 frames (1 = preloader, 2 = instances of symbols, 3 = the main page/view). I've gone through and optimized all my static bitmaps/movieClips and removed any symbol that I've exported for ActionScript from exporting in the first frame. Even after all these steps frame one is still the longest to load (797kb on a 32.6 kbps simulated download), only showing the preloader when the whole file is at 86% complete. Any further steps to take to get frame one's size down?

I've got this simple GUI that has a search box and a couple result fields for "Word" and "Definition"...I've also got an XML file with about 800 or so terms and definitions.Currently the flash works just fine, it reads in the XML glossary, splits it into a word array and definition array and when I search through it, it creates a List filled with terms that match the string that I search for. We wanted it to update the list of possible matching terms each time you changed the search term: a, ap, app, appl, apple... etc.
Everything works, its just incredibly slow when you throw 800 terms at it to search through.I was wondering if anyone could either optimize my search somehow, show me another way of doing it.Here is the code pulled from the whole GUI.
ActionScript Code:
var glossary_xml:XML;
var xmlReq:URLRequest = new URLRequest("glossary.xml");[code].........
