ActionScript 3.0 :: Set Alpha To 30 Percent In Constructor Function - TypeError
Apr 7, 2009
I am new to AS3 and writing classes and keep having a hard time with these error messages I am getting. I have the following AS:
public class PrevNextNav {
public var back_next_nav:MovieClip;
public var next_btn:SimpleButton;
public function PrevNextNav() {
back_next_nav.next_btn.alpha = .3
} .... etc.
The class works fine, except when I try to set the alpha to 30% in the constructor function, I get this error in the output window.
TypeError: Error #1009: Cannot access a property or method of a null object reference.
at _classes::PrevNextNav()
at InteractivePilotDocument()
If I comment that line out, all is good. What does this mean?

I want to achieve the effect on [URL]. The effect on the left on the about page in which when the mouse moves over the alpha of the object goes to 0%. I have all the layers set up with masks and all but need the action script. I tried applying the following code to a mask which I converted to a movieclip.
on(rollover){
this._alpha--;
}
But this did not work for some reason.

what i'm trying to do is get a movie to duplicate movieclips when the original movieclip is dropped onto a target.what it does is,
1. click, drag movie clip to target.
2. drop, released.
3. duplicate movieclip appears in the ORIGINAL position from where the original movieclip was picked up.
4. and keep the dropped movieclip in place.
i don't know why i get,
TypeError: Error #1007: Instantiation attempted on a non-constructor. at Untitled_fla::MainTimeline/dirt_UP()
Code:
function dirt_UP(e:MouseEvent):void{
if (e.target.dropTarget != null && e.target.dropTarget.parent == this.shirt){ e.target.stopDrag();
startX = e.target.x;
startY = e.target.y;

I'm making a class called 'player', and really, I don't need a constructor function for it. Do you just outline the function, but don't put anything between the curly braces? Also, I'm a bit new with access levels. If I wanted my functions from my player class to be accessible from the main class, do I make them public?

Basic OOP question... I want to add a couple functions to the Array class so that my program will be amazing and make me rich and famous overnight. So I create a new subclass NewArray which extends Array. Do I need to write a constructor method for NewArray? If I leave it blank will it just use the parent's (Array's) constructor method?

If I pass variable(s) like this in document class action script file(I'm not even sure if I can pass more than one variable):
Code:
ballPointRight = new BallPointRight(ball, xDir, padScreen) ;
And now the BallPointRight's action script file:
Code:
package {
import flash.display.MovieClip;[code]....
doesnt work since it doesnt recognize variables...

I am trying to make a subclass of flash.display.Loader, which should do something when the loader completes loading the content. So I do addEventListener(Event.COMPLETE, onComplete) on my loader subclass. But this Eventlistener is never called. Is this supposed to happen? Can't I use an Eventlistener on the class that dispatches the event? My code looks like this: public class MyLoader

I´d like to know how could use the Timer class extended.I´m trying to pass a parameter to the constructor function, so I can use it inside the listener.
Here´s example:
[CODE]
package { import flash.utils.Timer import flash.display.DisplayObject public class ChangeColorTimer extends Timer { public static const CHANGE_COLOR:String = "changeColor"; public var obj:DisplayObject public function ChangeColorTimer(delay:Number, repeatCount:int, obj:DisplayObject ) { super(delay, repeatCount) this.obj = obj } } }
[/CODE]
That was the ChangeColorTimer that extends Timer.Now, I´d want to know how would I use ChangeColorTimer.I thought it was the same as using Timer.I´ve tried this:
[CODE]
public function changeColor(mc:MovieClip):void { var colorTransform:ColorTransform = new ColorTransform() colorTransform.color = 0xEE0000 mc.transform.colorTransform = colorTransform var changeColorTimer:ChangeColorTimer = new ChangeColorTimer(400, 1, mc) changeColorTimer.addEventListener(ChangeColorTimer.CHANGE_COLOR, setNormalColorListener) changeColorTimer.start() } private function setNormalColorListener(e:Event):void{ trace("called") }
[/CODE]
I called changeColor, but, I don´t get "called" in the output from the setNormalColorListener listener.

is it possible to get the name of a calling function or the constructor from the called function? is it possible to determine the previous function of the thread?
i would like to call some setter functions from my constructor and have my setter functions determine if it was the constructor that called them.
currently, i'm setting a boolean for this functionality, but perhaps there is another way?
public function Constructor(myNumber:Number)
{
this.myNumber = myNumber;

I have a series values I'm passing (from an FLA) into the constructor of a class. I just want to make clear in my mind that, the only way to pass the variable params, to the function nowDoThis, you'll need a dispatchEvent or a custom event to send it along ?
As an example:
Code:
// constructor
public function MyFunction(_param1:uint, _param2:uint, _param3:uint) {
param1 = _param1;
param2 = _param2;
[Code].....
I have only a vague understanding of using objects and dispatch events. Isn't this something that people need to do all the time?

Some of the top level classes can be instantiated as well as called as a function (e.x. new Number() and Number(), new Boolean() and Boolean(), new Array() and Array()).
Usually this is used for type conversion or as a shortcut for instantiation. I would like to be able to do the same thing:

What I wanted to do originally was to create a logging class to interact with Flash/JavaScript, and be cross-browser compatible. I wanted to be able to use the log function as an alias of a method in the log class. This got me to wondering whether I could implement a custom casting function just because. I've now realized it's not possible, but was fun to play with anyway.

I am importing several external files using the Loader-class, and one of them is an swf-file. When doing so (I had done it successfully before, so did not expect any issues), I ran into all sorts of errors, and finally Flash crashed.
I put down a trace in the constructor function, and it didn't trace just once, but kept on tracing, suggesting that the constructor was stuck on loop. I guess the loading of too many of the same swf is what causes flash to eventually crash.
Here is my code (the swf im loading is now a simple test-file which contains an image and no code):
private var slides:Loader = new Loader();
public function DocumentClass()

I've got a simple program that consist of a document class and a buttonTemplate constructor class. I need to call a function called updateText that should be in the document class, when someone clicks on a button. So that after each button is clicked, it updates some text in my document class. My event listeners for the buttons are in the buttonTemplate class. My question is, how do you call a function in the document class from a constructor class? Here is my simplified code below
