ActionScript 3.0 :: Variables Outside Of A Function?
Jan 14, 2010
I need to be able to use a function to change a variable outside of it, and it seems like global scope and the like went out with 2.0 and I need to use 3.0.I would just have the function return a value, but I'm using an 'addEventListener' which has the event and then the function inside.
Example:
Code:
var finished = false;
myLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, done);
function done(evt:Event) {
[code]....
How can variables be changed through a function when you can't set the scope or return a value through it?

I am new to AS3 and building a simple flash banner. There will be four movie clips consisting of just one word each (in the sample below I'm just using rectangle for now). When moused over each word will show a rectangle with a message in it, like a large tool tip. I have a rudimentary version working fine, see code below.
Question 1: Is there a way to just write on function which will work with all four buttons changing the message, say using variables like AS2?
Question 2: Does the code below look relatively efficient? I'm sure there are better ways to write it.Here's a link to the rudimentary version, http:[url]....

I need to access the contents of a variable that is filled inside a function, but is declared outside the function.. [URL] says that if you declare the variable outside of the function the variable should be accessible even when its content is filled by a function. I have declared the imgs variable at the start, outside the function, as an array. After that the function retrieves a string from the URLLoader and splits that string into to the imgs array/variable.

Hello, I'm trying to minimize code, so I am trying to use functions, and need to pass some strings through them in order for it to work.I believe I may be doing this incorrectly, so could someone please take a look and tell me what I'm doing wrong? On one of my movieclips:
[code]...
What that previous code should do is loop through all movieclips in the game and if it's not named player, move it in accordance to what "Direction" is.If the player is pressing the arrow down key, it will change "Direction" to "DOWN" and hopefully pass it.

How one would go about switching 2 variables around. For example if I have
Code:
a = 5; b = 3;
Then use the switch function and get:
Code:
a = 3; b = 5;
Is there any such thing?

I'm pretty new to AS, I understand that whatever variables you have inside a function will be discarded once the function finishes? I need the value of a variable that's inside a function, I've tried declaring it outside the function, and also give it an initial value, but it seems that when the function finishes the variable goes back to it's original value.

By chance does anyone know if there is a way to make a set function for my class that will run regardless of what variable is being set? like if someone does..anInstanceOfMyClass.anyVariable="whatever";it will always run function X.I want my code to have a function that runs every time someone tries to set the value of a variable in my class, or create a new variable that does not even exist yet in the class.

I'm making an animation of calculating a projectile motion with air resistance based on Python code from [URL]. I include the relevant portions of codes as follow. I'm not familiar of the vector object in AS3 so I translate them into variables as follow:
Actionscript Code:
//timer related variablesvar
fps:uint = stage.frameRate;var interval:Number = 1/fps;
var myTimerYes:Timer = new Timer(1000/fps);
//air resistance timermyTimerYes.addEventListener(TimerEvent.TIMER, startSimYes);
function startSimYes(e:TimerEvent):void{
[Code] .....
The timer activates when the user clicks the start button. The start buttons set the variables for the timer function. The variables are created at the start of the actionscript file. The code of the start button is:
Actionscript Code:
start_btn.addEventListener(MouseEvent.CLICK, goTimer);
function goTimer(e:MouseEvent):void{m = int(airText_mc.mass_txt.text);
A = int(airText_mc.refA_txt.text);
Cd = int(airText_mc.Cd_txt.text);
rho = int(airText_mc.density_txt.text);
[Code] .....
The result I get is the aX = 0 all the time, even after the update I specified in the timer codes. I can't understand what's wrong with the code, it's supposed to be updating every time the timer goes on.

I've been searching this problem for a while and have tried a number of solutions found on google but nothing has worked so far. I'm sure this is a common problem, but due to my lack of flash knowledge I can't logically work through it as I'm used to windows form development, it makes sense to me that the function could access the variables I have defined but they dissapear after the .onLoad event. Does anyone know the common solution to this problem? I want to be able to pass the xml details into the local variables so I can pass on the details into a dynamic text field when movies are hovered over etc
var myXML:XML = new XML();
myXML.ignoreWhite=true;
var nav1Text:String;

I'm working on a function that checks for 2 things to pull up the correct .swf file. I have to check for 2 things
·_global.theYear
·_global.theDate
Is there a different way I could write this function to say something like:
checkAll(_global.theYear, _global.theDate) = function(){
loadMovie(_global.theYear,_global.theDate".swf", 1);
}
So when a button is pressed, it runs the function above and fills in the variable. Names in the .swf name, does that make any sense, am I on the right track? Because all the .swf file names are all consistent such as 2009_18.swf, 2007_5.swf., etc. The only problem I see is there are 2 sets of buttons, one when you press it sets the _global.theYear variable and the other sets the _global.theDate variable.
So would one button look like this:
mybtn.onPress=function(){
checkAll(2008,_global.theDate);
}
And the _global.theDate would be set with what the current var is set at as?

I know that as long as a I declare variables inside a function I can only call them as long as the scope of the function is active. Outside of that function the variables don't exist. Is there any way I can create those variables inside a function and use them outside of it?

I have been playing around with combining flash and PHP/Mysql for some time now, mainly sending one flash variable to a PHP file and then retrieving a result and turning it back into a different flash variable. My problem is i've got to the stage where I need to access these variables from other functions. Now I think I need to find some way of defining them outside of the function, maybe using global vars? Well i'm not gonna pretend I know anything about it. The two functions from which I access my PHP variables is as follows:
ActionScript Code:
function btnDown(event:MouseEvent):void {
var variables:URLVariables = new URLVariables();
var varSend:URLRequest = new URLRequest("http://localhost/test.php");
[Code]....
So I need a way to access the phpVar1 variable in a totally seperate function

I'm using this code
Code:
on (click) {
var x = 1;
print(x,"bmovie");
}
To print out the current page as displayed on the screen. The command works great, but when the button is pressed all of my variables seem to be reset, along with various combo boxes.The print function works as intended except clearing all my values .Is there a way around this?
Edit: I just ran a small test on a blank .fla with 3 buttons 1 - set variable = 1, 2 - trace variable, 3 - my print code
This does not clear the variables like it does in my application.What exactly goes on during the print function? If I can isolate and trace the problem, I could find a fix for it, but I have no idea whats going on.
