ActionScript 3.0 :: Very Simple Explanation Of Get/set?
Aug 31, 2010
I read a lot about accessors or getters/setters, but to date I cannot really understand what they do. The language describing their use is just beyond my comprehension, not being any type of developer nor an advanced AS3 user.Can someone provide, or point me in the direction of, a VERY SIMPLE getter/setter example that includes WHY it would be used as well as HOW to use it? something small that doesn't use just comments within functions (like "// here is where you do xyz"), but actual code (the actual doing of xyz). That way if I want to play with it and build on it I can.

For example, I have a function that is triggered by a button click This function loads an external swf.I then set a global variable swfLoaded to true, with the idea of having an if condition that executes removeChild(loader) if swfLoaded is true.When trying to execute removeChild(loader), I get an error telling me that it must be the child of the caller.I've seen the code below, which loads a default swf, but I don't want a default swf - I just want one loaded if the button is clicked, and then if another button is clicked, the original one to be removed before the next swf is loaded.How do I make this code work without loading a default swf, just loading one once someone clicks a button, and then removing it?
var Xpos:Number = 110;var Ypos:Number = 180;var swf:MovieClip;var loader:Loader = new Loader();
var defaultSWF:URLRequest = new URLRequest("swfs/eyesClosed.swf");

What I get is that you can pass a function to another function as an argument so that the function that you pass to can "call back" that particular function.
All good. However, I'm unclear about a couple things: Why exactly is this beneficial? is this the same thing that the addListenerEvent method does when you pass it a function as an argument for when the event fires?

I have been reading Learning Actionscript 3.0 for about 1-2 months now on and off and i have stumbled across a paragraph that I don't quite understand concerning the position of a navigation bar buttons.
Code:
var btnNum:int = 5;
var spacing:Number = 10;
var navBar:Sprite = new Sprite();
addChild(navBar);
var btn:SimpleButton;
[Code] .....
The current button is positioned horizontally (line 10), offset by the spacing set in line 2, plus the width of the button and another spacing gap for each button in the loop. Therefore, the first button is positioned only 10 pixels to the right of the container's registration point (spacing, plus zero times the sum of the width of the button and spacing). The last button is positioned 10 pixels to the right of the container's registration point plus 4 times the width of the button and spacing. The vertical position is also set, moving the button down 5 pixels. From the above quote, I understand that the button the first button is placed horizontally, but i don't understand what is after it. What the paragraph means and how it does it's position.

I'm a relative noobie struggling to understand object registration points / center points. For example, in this image of an empty movie clip from an XML gallery I'm customizing for my site, there is a circle with a cross and an empty circle.
Can someone point me to a thread or article that explains object registration points, how they relate to each other and how (and why) to move them (or not)?

Code:

Flash is not in my toolset, but I am an old Director jock and have spent some hours dipping my head into the Flash manual. I suppose that makes me a promising beginner-level poster. I'm working in CS5.
I need to make a simple Flash-based sound player for a website for a newly-released novel (http://www.bearriverbooks.com/index.html). I want the user to click on what appears to be an icon (or image), which kicks open a simple controller and starts playing a sound file (a radio interview, which I will probably export using Flash's voice compression). Nothing fancy. Just want the visitor to hear the sound and be able to apply simple controls (stop/start/rewind/volume).
I can learn ActionScript, I suppose, since I used to dream in Lingo, but my life would be a lot simpler if I could just publish a controller without having to roll my own. I'd like to think there's a magic button somewhere that can do this, but I haven't found it yet.

I've finished my flash file. I created it with Flash CS3. I didn't use any scripting, dynamic stuff, etc.. It's a simple flash movie of vectors/tweening.I want to insert it in my homepage, but when I publish it, I get quite a lot of code. I've been looking around & I see some sites that have all this javascript & some that don't.Could someone help me identify the correct way to embed my .swf file? I'm not a fan of .js since it doesn't work if it's turned off in a user's browser. I want my .swf file to play as long as the visitor has Flash 8 or higher installed. And if they don't, I want to display a .png instead.[code]

I'm building a simple soundtrack in CS4 where files are loaded externally, and played according to the frame. So on frame 5 there may be music, and on frame 9 its stopped, frame 10 will be another soundtrack, etc.
I'm trying to build the channel in CS4. I've really looked around and the correct syntax is so confusing. This is what I have so far.

I am having trouble getting a simple animation to play properly, on a site designed by someone else, in IE. It works fine in Mozilla and Safari. In IE, on some computers, it shows up but there is a prompt about downloading a Shockwave add-on. On other computers it doesnt show up at all. Going from Mac to PC is also presenting problems. I'm freelance, so it's not like I'm in the office with these other people, so I only know what's going on with the 3 pc's I have at my disposal; which is as described above.

Draw a rectangle using the rectangle tool; select the text tool and create a text box inside of the rectangle, and type in BEGIN; make sure it fits inside the rectangle; select entire image by left clicking then dragging over it; convert to symbol button.
Then, I add in the code of going to keyframe 4 when released (which works fine). But when I test it out and mouse over the button, I can still select the text which gives me like barely any space where I can click the button to go to keyframe 4. This is reeaaallly annoying me. How can I fix this?

I am using Adobe Flash CS4. I don't know why I do the sample actionscript code here.
on (release) {
gotoAndPlay(1);
}
And now I'm dealing with a button function. I already created a box then press "F8" and choose button. Now I click on the button box, and press "F9" for the actionscript. It said that "Current selection cannot have actions applied to it" Then choose "ActionScript 1.0 & 2.0" Global Function > Movie Clip Control > On but "On" is disabled, how to solve this problem of mine to put this simple code.

I'm thinking about setting up a website (based on WordPress) to host video tutorials on interpreting CT scans.
In addition to simply letting the visitor view PowerPoint presentation videos, I'm keen on writing some sort of simple app that I can embed in the blog to allow the visitor to scroll through a series of images (i.e. a scan).
I usually code in REALbasic or Objective-C. What are my language options for making an interactive embeddable image viewer in a blog? The website needs to be able to be viewed on an iPad as well as normal desktop browsers.

How do you create a simple Health Bar for Actionscript 3.0? I have been searching for this for a while, and all I ever find are AS2 tutorials. AS2 dates back to about 900 B.C. ; it is an archaic language and it needs to be left alone, FOR GOOD.
