I'm currently having some trouble with referencing objects that turn out null on export. Basically I want the Document Class to run the code of another class that is the class of a MovieClip without having Error 1009 popping up everywhere in my output panel.

I have my main.swf which has class of Main.as which control everything.Then in main.swf I have 3 movieclips that acts as a button and they share a class of Button.as which controsl all the button functions btn1, btn2,bt3 are all place on stage and in Main.as I control their positions.When you click on a btn, it moves to a new location at the same time the other 2 btns will move as well.I can get the target btn that's been click to move just fine, but I can't get the other 2 btns to move and they all share the same class. I know this probably has to do with a targetting issue... I think. Is there a way I can make the connection in same Button.as class file? Or do I use like some global event dispatch?
View 2 Repliesso i'm working mostly in a main class file. up until now subclasses (or the class for objects that i'm using in my game) have really only contained methods that controlled property values, and properties. however, i'm now interested in making an enemy in my game, but doing almost all the code for the enemy in the class file. i need to figure out how to communicate and check the object instance of the class against an object instance being controlled by the main class.
View 13 RepliesI have an array of temporary objects created in a for loop. The objects are of type class "Tile", a class I created. However, it appears that whenever I create a lot of tiles in the for loop, the program slows down indefinitely.
While the array is whiped at a later trigger point, I am thinking that perhaps these Tile objects are not being erased from memory. They are being created on the fly in a for loop, and the array is being reset to "array = []".
Are the objects still in memory or are they cleaned up when the array is set to []?
Can I access a static variable of a subClass' subClass? I don't want to instantiate it, just looking to get the variable because it has already been initialized by the subClass.example:

I have a movieclip with a class attached to it, so obviously i can acces it with commands of the kind this.* What i want to do, is delete the movieclip after some time (it's a bullet from a tank and I want it to be gone after explosion). I can removeChild it, but the code "this = null" doesn't work.Is there any way to get it out of my memory? Because now my application slows down and in 5 minutes it's unplayable...
View 6 RepliesI declare this tween...
ActionScript Code:
private var _tweenX:Tween;
private var _tweenY:Tween;
I even fire it off it when the player hits a corresponding button...
ActionScript Code:
museumGuy.gotoAndPlay("Walk");
_tweenX = new Tween(museumGuy, "x", Regular.easeOut, museumGuy.x,categoryPaintings.x, 40, false);
_tweenY = new Tween(museumGuy, "y", Regular.easeOut, museumGuy.y,categoryPaintings.y, 40, false);
_resetAnimation = true;
As you can see I have some animation stuff in there. I need to stop the museumGuy from doing his walk animation when the tween is over so I have this on the EventEnterFrame function I set up.
ActionScript Code:
if (_tweenX.isPlaying == false && _tweenY.isPlaying == false && _resetAnimation == true)
{
museumGuy.gotoAndPlay("Idle");
[code]...
how I can stop that? In my Init() I tried to state...
ActionScript Code:
_tweenX.isPlaying = false
but it doesnt like that either.I could fire off a tiny tween as soon as the app starts that doesn't last long enough to notice,but I really want to get a hold of how to control it.
Just wondering if anybody knows of an existing component that subclasses ComboBox but lets you specify an item in the list with a label like "all" or "none" that will set selectedItem to null? I've looked into writing one, and due to the internals of the component it looks like a lot of work, so I'm wondering if somebody's already done it?
View 3 RepliesI have a large creation in process that requires a lot of heavy animations and movement with vectors and really processor intensive. Just want to know, regardless of whether the project is huge or small, how to totally stop a class from working? I have three classes I am calling. "class1 = new Class1();" etc. When I am in the level, say, class2, I can still talk to objects in class1 even though I removed the class listeners within that class1 after I was done using it. It still is able to be called upon, and still running something in the background that I can't figure out what it is. I just want to know, rather than searching for whatever is causing the problem, can't I simply null the class that I never ever need to use again?
I tried that, but then I ran a trace and it still tells me that it is a class object. I reckon its because I have a "public var class1:Class1" etc, which means they will always have those objects associated with them, but still. I want to totally get rid of it for garbage collection, and because I don't want to use some of them at all, ever again. So basically, what is the best way to get rid of classes so that they aren't hogging up resources any more?
I was just wondering--and it's probably an obvious question really--if I make an object null and that object had one or more event listeners registered, are the listeners removed?
for example:
Actionscript Code:
object.addEventListener(Event.SOME_EVENT,callBack);
function callBack(evt:Event):void
{
object = null;
[Code].....
In this case have I removed 'object''s listener when I made the object null?
This is the scenario:
[AS]
// Assuming a lot more properties are added to all objects
var parent:Object = new Object();
var kid:Object = new Object();
var kidToy = new Object();
[code]....
Does making the parent object null recursively release all memory used by all subordinates in the hierarchy?
I have a flex application with two objects: a parent widget (called an IBaseWidget) and a child widget (called a HelperWidget2).When the user clicks on a help link, a helper widget is loaded into the list of base widgets and then displayed for the user.However, when I try to access this child widget by casting the base widget in the collection to the child widget type,the child widget returns null and I am unable to work with the widget.The following snippet correctly returns the widget ID of the newly added widget and dispatches an event to load the widget:
var id:Number = WidgetManager.getInstance().getWidgetId("Helper");
ViewerContainer.dispatchEvent(new AppEvent(AppEvent.WIDGET_RUN, id, openQuickQueryCanvas));[code].........
The problem is that helperWidget above always returns null, meaning the cast isn't successful.
I have an ASP.NET 2.0 web service and am using it in (among other things) an Adobe Flex application. I have a strange issue where if I send an object to the web service using soap with some fields that are null the webservice is actually creating new objects on the other end (and not putting any data in them).[code]In this example SomeFieldThatShouldBeNull and SomeFieldThatShouldBeNull2 are being created as new objects by the webservice. It is vital for the application that does not happen.
View 1 RepliesI use this pattern to test for undefined and null values in ActionScript/Flex :
if(obj) {
execute()
}
Unfortunately, a ReferenceError is always thrown when I use the pattern to test for child objects :
if(obj.child) {
execute()
}
ReferenceError: Error #1069: Property child not found on obj and there is no default value.Why does testing for child objects with if statements throw a ReferenceError?
I've started dabbling in switching out the context menu and adding other functionality to it.I tried creating a new ContextMenu and set it to the property of my stage. No go, it says Stage does not implement this method or property. Which is kind of bizarre since Stage inherits from InteractiveObject which does indeed have the contextMenu property.
So I tried to just trace out the contextMenu, and it returns null on whatever displayobject I try it on. A MovieClip, the stage itself etc..What am I doing wrong? In my world, and according to the documentation, I should be able to change the contextMenu.
I'm having trouble with my code. I keep getting this error
TypeError: Error #1009: Cannot access a property or method of a null object reference.

I believe it has something to do with the array, considering it works when I remove the array stuff. What I'm trying to do is to be able to move objects through an array with my gravitate() function in the Grav Class.
stage.addEventListener(Event.ENTER_FRAME,onLoop, false, 0, true);
for(var i:uint=0; i < numParticles; i++){
var p:Grav = new Grav(5, 0xff0000, Math.random()*250, Math.random()*250);
addChild(p);
particles.push(p);
} function onLoop(evt:Event):void {
//for(var i:uint=0; i < numParticles; i++){
//particles[i].gravitate(1,1);
//}}
I'm working on a dress up game and I have one problem with it. There are so many items of clothing (which are movie clips with the basic drag and drop code) that I had to create different pages for them. I have buttons (labeled like "dresses", "pants" etc) that when clicked on make that group of items appear. So, great. It's just that once an item has been dragged over to the doll and put in place, I want it to STAY there. But as soon as you click on a different page, that item disappears. Is there any way to make items stay on the doll, even though they're part of a page?

I'm sure it must be a simple error, I can get the logic working when it just traces something on the screen but i can't get it to generate an "enemy"
I have an object called MenuButton that extends MoveClip.I want to arrange 8 MenuButton objects in a cirle. The easiest way to do this would be to use a for loop and an array of MenuButton objects.The problem is, I'm not exactly sure how to make an array of objects. I've seen some code online, appears to be AS2 and I need 3. It's also not very clear if it does what I need it to.It would also be cool if I was able to name the buttons sequentially, i.e.: button1, button2, etc. I've seen AS2 code for that, but again it's not too clear if that'll work the same in AS3 and if the code I've seen will do what I need it to.

View 7 RepliesI am making an animation that tweens two different objects at different speeds dependent on the position of the mouse. This is working fine, however, when the user takes the cursor outside the flash box and enters the frame it jumps to that position.
I have created a tween for this first instance however, if the user continues to move there cursor before this tween has finished it continues to jump.

How can I make a mouse event ignore, or skip over another object? Say I have a small Sprite on a Large sprite, I want it to act as if the small sprite isn't there, and pass the mouse events directly through to the larger sprite behind it.

View 3 RepliesMaking Objects Appear Inside a View Area
View 3 RepliesI have a movieClip, with other movieClips inside of it, objects that I want when hit to lose points. But when I have the movieClips inside that one, it just has a giant "boundry box". I want the points to go down when you hitting only one of those items,instead it just goes does throughout the entire thing.
There is no way for me to scroll all those objects across the screen without either making a tween on the main timeline for each object (almost 20), or somehow making a giant movieClip scroll all of them all the way across, bypassing the first boundry box, and acknowledging the movieClips.
