ActionScript 2.0 :: Passing Arguments By Reference?
May 12, 2005
Is it possible to pass arguments "by reference" instead of "by value". I know it's possible in almost every programming/scripting language I came across until today, but I didn't find any hint for doing it in Actionscript For those who don't know what "by reference" means: If you want to pass a Number to a function, say
Code:
var mynumber:Number = 5;
calculate(mynumber);
and you change the value of the argument inside the function, e.g.
[code]....
then the call to calculate normally does NOT change the value of mynumber because you have passed mynumber "by value", which means the value of mynumber has been copied to the num argument. This means mynumber is 5 all the time.Now sometimes u want to be changing arguments given to a function inside the function, and this is where u will normally use references. Passing mynumber "by reference" would mean that after calling calculate the value of mynumber will be 6...I know complex Objects like MovieClips are passed by reference. But how to do it with simple DataTypes like Number, Boolean etc.?

I have a movie clip that contains several movie clips, only one of which should be shown at a time. Which one is shown, depends on what buttons the user selects.Having trouble with the syntax for passing the argument in a button to the function that controls the tweening of the clips. (When I hard code the references into the function, it works, so I know the basic function is ok).There's a clip called 'slide1_mc' which contains various MC's to be shown based on user selection (in this case, using 'system' clip as the first one already showing). Here's the code in the parent clip of that item:
Code:
var currSection = slide1_mc.system_mc;
function changeSection(newSection):Void {
TweenLite.to(currSection,.3,{_yscale:200, _xscale:200, _alpha:0});
[code]....
Here's one of serveral buttons that will control the content to be seen:
The code in the button is:
Code:
var changer = slide1_mc.software_mc;
smallButton.onPress = function() {
_parent.changeSection(changer);
};
So - the initial part of my function works so I know my 'external' initializing of "currSection" is working (that clip is zooming/fading out)... but then the clip that I want to fade in isn't doing anything.

i have a music jukebox, with ten buttons. in the first keyframe, of the main timeline, a put a function that will be used for every button to load the mp3 to play. The problem, is that when i pass the arguments on each button to call the function, the "filme" and "som" arguments are lost.
here is the function:
function carregaSom(filme, som, url, msg1, msg2, tempoComeco){
_root.createEmptyMovieClip(filme, 1)

You can do this:
PHP Code:
public function (args ...)
To take in any number of arguments. Is it possible to then give the content of that args array to a new function:
PHP Code:
public function bla (args ...){
pleh( changeArrayIntoArgs(args) );
}
So that that would be the same as just passing arguments manually. lets say bla got 3 arguments:
PHP Code:
bla(v,vv,vvv);
So that bla then executes:
PHP Code:
pleh(v,vv,vvv);

I've drawn a pretty button in Flash and given it the Class name PausePlayButton. It extends PlayerController, which allows it to toggle on and off and control whether a MovieClip is playing or not.When I instantiate it, I want to pass a reference to the MovieClip it controls into the contructor so that PlayerController has access to the MovieClip's public methods. However, I can't pass a reference into the constructor of PlayerController, unless I can pass it into the constructor of the symbol itself and call super. But where is that constructor? How do I give the button a reference to another object?

I'm having trouble with the constructor for a custom Class tied to a library MovieClip.
Say I have a MovieClip in my library named Circle, which is tied to the class com.shapes.Circle . I want the Circle class contstructor to take 2 arguments, xScale and yScale:
public function Circle(xScale:Number, yScale:Number) { }
However, if I try to call that from in code, for example Circle ball = new Circle(3.14,2.0); , I always get an "Incorrect number of arguments. Expected 0" error.
Is it possible to have a custom class tied to a MovieClip that can take arguments, or does Flash not allow this? I'd asked about this before and thought I figured it out, but from looking at it now I apparently hadn't figured it out and had resorted to a sloppy workaround; I'm hoping to fix it now.

Is there any way to pass an argument to a function being called by a ContextMenuItem?The effect I want would be what one might expect from this pseudocode:
Code:
var cm = new ContextMenuItem("Start Alt", set_row_style('start_alt_here'), separatorBefore=true, enabled=true, visible=true);
Which obviously doesn't work, or I wouldn't be asking.So far I've tried using the captions as a basis for a switch condition, which works.
Code:
function set_row_style(obj, cm) {
switch (cm.caption) {
case 'start_alt_here' :
...
But I'd rather not use an arbitrary string as part of a function.The only other option I see is using a listener for each ContextMenuItem, then calling the function with its arguments from there.Is there any more direct a way to pass an argument to a function from a ContextMenuItem?

I want to have an array, where each value is a function, where each function also has a set of arguments.
What is the correct syntax for setting a value of an array as a function?
Lastly, how do I pass arguments into the array's value?
Code:
var funcA = new Function(a:Number, b:Number){return a + b};
var funcB = new Function(a:Number, b:Number){return a - b};
var funcC = new Function(a:Number, b:Number){return a * b};

Is it possible to pass variable as arguments for a function? I wish to update a boolean variable via a function, by passing the name of the variable to the function, like so:
Code:
function ENVSegment(curSegment:Boolean, nextSegment:Boolean) {
curSegment = false;
nextSegment = true;
} var attackSegmentIsRunning:Boolean = false;
var releaseSegmentIsRunning:Boolean = false;
[Code] .....
Much shorter, and easier to understand. Also, less repetition of the same blocks of code over and over...

I know that in C# when you pass an object (non primitive) to a method the following is true: A reference to the object is passed Changes made to the object in the method are reflected outside of the method. Also, you can pass a reference to a reference in C# e.g this.changeObject(ref myObject);, in which case: Changes to the object and also to the ref are reflected outside of the method e.g. myObject = new new List(); would change the passed objects referred location. Is this possible to do in Flex/Actionscript - can a ref keyword be used?

TypeError: Error #1009: Cannot access a property or method of a null object reference.

It took me hours to figure our why this was returning the wrong value - when assigning one array to another it passes by reference not Value. I need a way to force it to pass by values. e.g. copy the existing array and have the second array reference it, so i am free to modify the first array without changing the values of the second.[code]From the example above You see that in Actionscript when assigning one variable to another it does it my reference not value. So when you chage the value of one array it changes the value of the other automatically.I need to have the "test2" variable reference the "test1" array only by value so if modify "test1" the values of "test2" won't be modified.
