ActionScript 3.0 :: Explain Syntax For (X ^ (X >> 31)) - (X >> 31)?
Oct 15, 2009
explain in very very basic terms (or direct me to tutorial) what is happening in this syntax:
[code]...
this was part of and example on how to optimist code (posted in this forum awhile ago), specifically for replacing either:
[code]...
I understand how the brackets work, and that X is a variable (I presume a Number).
I assume that '^' == 'to the power of'.
I dont understand why they are using >> or 31 at all.

using action script...
stop();btn001_btn.addEventListener(MouseEvent.CLICK,showimage1);function showimage1(event:MouseEvent):void { gotoAndPlay(10);}btn002_btn.addEventListener(MouseEvent.CLICK,showimage2);function showimage2(event:MouseEvent):void { gotoAndPlay(20);}
however movie is playing without stopping to "Listen" for a Mouse CLICK. Images placed at frame 10 and 20 should appear only when CLICK'd.
This code is straight out of Classroom in a Book CS4.

From what I have gathered, _rotation uses radians?Basically, my initial goal was to make a movieclip rotate towards the mouse. I'm not very good at trigonometry.Using the help files I found atan2 which seemed to be what I needed. A little fiddling got me to this code:
var xDist:Number;
var yDist:Number;
var angle:Number;
onMouseMove = function () {
[code].....
However,the _rotation is opposite what is expected. This is not a problem as I can just flip the movieclip. But really what im here to ask is, please ecplain this code for me? I don't correctly understand how atan2 works.. and why it needs to be *60.Basically: How to get a movieclip to rotate towards the mouse.. and why does the code work, I want to learn trigonometry.

I've a developer which has given users the ability to download a zip archive which contains an html document which references a relative javascript file and flash document.The flash document accepts as one of it's parameters a url which is embedded in the html document. I believe that this archive is meant to be used as a means to transfer an advertisement to someone who would use the source to display the ad on their site, however the end user appears to want to view it locally.When one opens the html document the flash document is presented and when the user clicks on the flash document it redirects to this embedded url. However, if one extracts the archive on the desktop and opens the html document in a browser and clicks the flash object, nothing observable happens, they will not be redirected to the external url.
I believe this is a security risk because one is transferring from the local computer zone to an external zone.I'm trying to determine the best way to explain this security risk in the simplest of terms to a very end user. They simply believe it's "broken" when it's not broken, they're being protected from a known vulnerability.The developer attempted to explain how to copy the files to a local iis instance, which I highly doubt is running on the users machine, and I do not consider this to be a viable explanation.

I was wondering if there is any easy tool to use in order to create a start up video? I know there is the Adobe After Effect option, which is extremely expansive.
any tool that allows you to create an animation, easily? for a startup site, a video that explains what the startup do?

I am doing a project on an interactive website that contains flash animations. I have to incorporate a voice that explains what is happening in the animations. I am using my own voice for this. I have recorded my voice and saved it as .mp3 files. between each animation there are about 6-10 audio files. I am pretty sure I can import the sounds into the flash library and drag the sounds on the timeline and sync the sound with the animations that way but is it possible to control the sound using actionscript as I have to incorporate buttons that allows the user to play, pause and stop the animation and the audio. Or can I only use actionscript to achieve this.

I have a software project, which involves complex process and calculation. Rather than writing it's logic and business flow in a document, i want it to be explained in some sort of animation visually, which would be easier for some one new to my project.

I've got a for loop and some fuctions working, but can't get one line of code to work. The red line below is what I'm having a hard time with. I'm calling a function called "moveit". If I insert moveit(x1, y1); then it works, and my movieclip is moved to the x and y positions that I specified for item #1. Though I want it to work for 10 items (I only have coordinates for two here, and will add the rest later).
I've searched my ActionScript book and just can't figure out what the syntax should be for calling that function.

but for some reason it isn't working. My xml file is loaded in and is written below.I need to be able to target the nodes numerically,

This animation I'm working on has a dozen pairs of movie clips (with only two library items, one for each type in the pair) with instance names of the form "x" and "xgoal" (this is a drag and drop thing).When I'm writing AS for the "x" clip, how can I refer to its "xgoal" generally? I tried something like:goalName = this._name + "goal";And then using the goalName variable in my dot syntax (retrieving the _x coordinate for the goal clip):this.xgoal = _root.goalName._x;But, of course, that did not work. How can I get around this?

I have an array like this:
Code:
var myData = new Array();
myData["name"] = "John";
myData["Age"] = 35;
What is the syntax to loop through and get the key and value? I have tried for each and for in but they just give me the value of "John" or "35", how can I get the key e.g. "Name" and "Age"?

I'm porting an existing java library to actionscript and since they are both realy similar, 95% of the work is simply flipping variable and function definition around.
public int foo(int bar) {}
//converts to
public function foo(bar:int):int {}
Is there a tool to automate the transition between java syntax and actionscript? I'm not looking to compile java to swf, just transform the source code to be (often nonworking) actionscript.
