How do you guys reference one of multiple objects? Every recent project of mine winds up having a bunch of items pushed into an array, and I find out which one to manipulate like this:
Code:
function myFunction():void
{
index = e.target.name.slice(5,7); // object is named "item_1"
myArray[index].x += 5 (or whatever);
}

I've learned it reading a tutorial over internet, but I want to know where I can find more samples on how to reference objects in AS3. For future codes, I want to add hitTest and the like.
var obj:Object = null;
recursionTest(0, obj);
trace("obj: " + obj);

How can i reference objects on stage so i can push them into an array using a loop?[code]...
View 2 RepliesI am creating a generic button that will remove items created dynamically in a movie clip container from memory (not just from the display list).
To track which item the user has selected for deletion, I have a click function that stores the name of the clicked object in a variable called objName. I then store a reference to the object itself in another variable called targetObj. I can then easily remove the object from the stage like this[code]...
How do you refer to specific named instances of objects (buttons, movie clips, text fields, etc.) in different scenes? I made two scenes with button1 on scene 1 and button2 on scene 2. My code is below. The button2.addEventListener line gives the error "cannot access a property or method of a null object reference." Removing that line removes the error and button1 switches scenes. What's the proper way of referring to button2?

I want to loop through an array of map tile coordinates, place a tile on the stage for each coordinate, and put a reference to each tile instance in a separate multidimensional array called mapRef, where the tile instances can later be referenced by their coordinates in mapRef. Is this line (excerpt from the code below)... Main.mapRef[i][j] = mapTile;.[code]
View 3 RepliesI am trying to add some Sprite objects as the contents of an array, and I would like to be able to "clear" them from the stage. I would assume that if there are loaders involved, I need to do
_imgArray[i].close();
_imgArray[i].unload();
And if I am using a sprite, I can do:
removeChild(_imgArray[i]);
None of the above work.
Currently I try:
for(i = 0; i < _localXML.length(); i++) {
var tmp:BMLink = new BMLink(_localXML[i], _bw, _bh, i);
_imgArray[i] = tmp;
_imgArray[i].x = (_bw + _mainpad) * i;
_base.addChild(_imgArray[i]);
But this doesn't work.
The class instances that are populating the array are all extending sprite, but they have their own individual loaders inside w/ progress events etc.
I'm doing an geometry object tranformations for a project. I need to have same rectangle across 4 parts in a screen.

View 1 RepliesI'm trying to reference objects on the stage in the current frame from a document class in Actionscript 3 in Flash CS3. In this example, I'm trying to get at a dynamic text field with the instance name "question_txt", but there are also buttons and other things I'll need to get at to put event listeners on and such.
I have "Automatically Declare Stage Instances" checked in the publish settings, so the references should be there -- in fact, if I try to declare them in the class, I get errors about a conflict with the name -- but when I try to reference these objects (in any of several ways I've now tried!) I always get Null.

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've got a situation that involves error #2174. Flash 10 apparently doesn't allow more than one upload/download/load/save at a time, but my code doesn't actually do that. A skeleton:

PBar contains two SimpleButtons (pBarProgress and pBarLoaded) and a MovieClip (pBarBg).I import pBar from the library like this:private var pBar:PBar = new PBar();and add it to a container MC on the stage like this:containerMC.addChild(pBar);Up to this point, everything works great. I can see pBar and its children on the stage when I run my movie. But then I want to start referencing and manipulating pBar's child objects, but nothing I do works. Ive tried ...pBar.pBarProgress.scaleX = 0;var pBarProgress:SimpleButton = Bar.getChildByName("pBarProgress") as SimpleButton; pBarProgress.scaleX

I'm having this frustrating error showing up and I have no idea why. Let me show you my classes and see if you can spot anything wrong.
First, here's my ILode interface:
ActionScript Code:
package com.schelterstudios.lodeSystem.flash.lodescode].....
So the problem I'm having is the compiler is throwing that 1000: Ambiguous reference error for any reference to instance.priority or instance.label. Why??? Instance is typed to IFlexLodeInstance, and IFlexLodeInstance lists method signatures of priority and label getters, and it inherits ILode, which lists method signatures for priority and label setters. What can I do to get the compiler to stop complaining?
My code is an external .as file. Google provides this code on their demo, which contains the this keyword:

Notice that I have 4 calls to console.log. The first 3 fire, but after the new GATracker statement, the 4th does not fire. I have a feeling that I'm overriding the entire package with the object created from new GATracker when I should be passing a different context. I believe the correct context I should pass is whatever this defaults to when not inside of a package/external file, I assume it references the main stage object.

In this Class, how they denote one as Weak Reference and one as Strong reference.
Internally Flash obviously keeps a list of the primitives drawn using Graphics so I wondered if you have many such primitives in a Sprite, can you re-position/remove/alter individual items rather than clear and re-draw everything? Or is this deeper into the bowels of Flash than you're allowed (or recommended) to go?
View 4 RepliesI'm using Zend AMF to send my remote objects to Flex. I've defined a Constant class and created getASClassName() method. Then I've created Action script class in flex.
Objects are send successfully, but they are deserialized to generic Objects in Flex instead of specific ones. EDIT: On network monitor in Flex I can see that AMF value is set to com.my.project.valueobjects.Constant. Although array from event.result contains Objects.

I 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 []?
What I have is a game with a Level object, inside the Level is a Player object, and they don't have instance names given, what I'm trying to figure out is how to do is make it so that the player can change the x or y properties of the Level object.
To be more precise, I'm making it so that when the player moves in a certain direction, he either moves accross the stage, or he starts moving the Level object around the stage, it'd be in an Event kind of function, now I can easily make the Player move, but I don't know how to make the Level object move which the player is inside of.

I will try to give as much detail as I can. I am creating an CRM application using Flex(Cairngorm 2)/Java/Hibernate. The basic problem I am having is this: I have a Customer class in Java that has an ArrayList of Address classes. I have a Customer class in Flex that has an ArrayCollection of Address classes. When I make the remote object call for a Customer I get back a Customer object in Flex, but the ArrayCollecion objects have a data type of Object instead of Address. If I try to call for a List of Address classes I get the same result. If I try to call for a List of Customer classes I get a list of Customer classes in Flex. Using tomcat 6 with the following jars:

How do I align a movieclip, which width and height is user-defined, inside another object (this one is static, though). Top-left alignment is easy, x=0 and y=0, but what about center, center left, bottom left, etc? Math(.round) i suppose, but how?I want an object (static) inside the movieclip (user-defined) to stay aligned to, for instance, the top right corner, similiar to the minimize, maximize and close buttons at the top right of your browser.. The height and width data is pre-defined by the user in another file.But that does probably not make any difference...
View 3 RepliesI want to create a flash movie which firstly loads a selection of images/objects into a portion of the frame. After this is complete, the user can then drag these objects onto another area and the object will be created where the user has chosen. The user can then drag another instance of the ojects onto the area.
For example, there is a background of a lake in one area. A selection of boat pngs are loaded in an area below the lake. The user can drag these boats and place them on the lake. They can drag a boat multiple times if they wish.
I have two movie-clips, one is small-box and another is big-box .Both are rectangular shape. Small- box has an index 0, and big-box has an index 1. Their x,y are same and big-box being big in size gets hide small-box. Now the problem is the listener attached to small-box does not fire as big-box is on the top of small-box. what would be the way to get listener fired when click on small-box area??

I have drawn colored rods which I have placed in the library and have put one of each on the stage with instance names likeblueRod_mc, etc.I place them around with time-line code like
blueRod_mc.x = 300.0;I have now created an Actionscript class called Problem.I build a new object from Problem which I have called Riddle.But when I put blueRod_mc.x = 300.0 in a method (of Problem),I get the message that blueRod is not accessible.So I triedstage.blueRod_mc.x = 300.0;That did not work either.
