Say my flash project has an object A. In object A is an event and it's corresponding listener B. How do I get listener and event B to function in my flash project? I remember it something to do about "focus", right? Or am I completely off target, ha?
View 4 RepliesI'm moving two objects accross the stage at different rates using the same function:

In AS2 I'd just use dot notation as above and it would work from anywhere or perhaps _root.red....

i have problem with swfLoader in flex, when i close following code in click method i can easly add many swf to main application
<mx:VBox id="content" width="100%" height="100%" ></mx:VBox>
public function doIT():void

when i close adding those swfs in loop i have the same error, it looks like child apps couldn't access certain objects that were instantiated by another child app, so what can i do?
I am trying to have a single parent class that a wide variety of classes can extend. Each of them has the exact same event listeners and remove function so I thought I would try to write the function a single time in the parent class.Parent Class:
Code:
public function removeMe():void {
/* REMOVE EVENT LISTENERS */
[code].....
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?
I'm currently working on a nav bar but I've run into a questionable situation. There are several links in the menu, and for each i'd like a mouse event on over and on out. Do I have to specify both of these events for each link, or is there an easier way to do it that I don't know about? Can you apply event listeners to multiple objects/functions?
View 6 RepliesI have a parent SWF (Parent) that handles user navigation between multiple children SWFs (Child_1, Child_2, Child_3). How do I add event listeners to the navigation buttons on the children SWFs so that the user can move laterally between Child_1, Child_2 and Child_3? I can think of two options but can't get either one to work:
1) The parent SWF sets up the event listeners when it loads a child. So, I use a loader on Parent to load Child_1 and in Parent add eventlisteners to Child_1.myNavigationform.myButton.
The problem here is that the Parent is only handing the loader instance and I can't think of how it would drill down to the individual objects within Child_1.
2) Child_1 adds the event listeners to its own objects. This just reverses the problem. Child_1 has no problem accessing its own buttons but when a user clicks them it has no way of accessing methods on parent so that Child_2 can be loaded.
I am creating a site with lots of big scrollable text-boxes in it. Each text-box object contained some text, and two buttons to scroll up/down with. The scroll buttons each had an event listener so the text moved when you clicked them.
These text-boxes were stacked on-top of each other with all except one having an alpha of 0. If I wanted to change which text-box is active I move it to the front and call a small TweenLite animation.
To the left (outside of the text-box objects) I have an object similar to a menu. It also has about 12 or so event-listeners (one for every button).
This turns out cause A LOT of lag an it's very troublesome for my laptop to run it. reduce the number of event-listeners on the stage and also the amount of text-boxes.
What I was thinking was to add the text-boxes using AS so I only have 1 on the stage at a time but I couldn't figure out how to do it. I also thought it might be better to just use 1 big event-listeners and from mouseX and mouseY decide which button the user is trying to push.
I see this type of apparent magic in all sorts of AS3 code, but here is a reduced example:
[Code]...
As indicated in the code comment, the loader variable should fall out of scope after the URLLoaderExample constructor. However... it still seems to be kept alive (not garbage collected) somewhere since the onComplete listener/handler is able to receive it cleanly. Where is the magic/hidden/global reference to loader that keeps it alive so that it can complete it's load operation, and then be handed to the onComplete listener/callback? Can this reference be seen somewhere?
To help with context... as a similar example, I know that the loader instance will have the onComplete listener registered. I also know I need to be careful to use removeEventListener at all times (?) to avoid potential memory leaks resulting from stranded listeners. What concerns me is that I don't understand where the magic loader reference is and whether (or when) I need to clean that up.
I'm trying to think of the best way to add event listeners(mouse events) to an invisible object which is quite large. A straight forward way I can think of is probably setting the object's alphy property to 0. However since that object is very large, it will probably have a huge impact in performance. Setting invisible to flash however, will stop it listening to events.
e.g. I have a massive area 4000x4000, but I only want the 2000x2000 area to listen to events.
Other methods I can think of is to have the smaller area in the layer below the big area, covering it from view, though I'm not sure if the lower layer can pick up events? another way is maybe just have the big area listen to events, but in the handler I'll write some code to check if its within the boundary of the smaller area.
I want to make a little game. What I need is to add event listeners to all of Tank objects inside the Battlefield instance. I just can seem to figure out how.
View 1 RepliesI have 3 frames each with a movie clip called map_mc. Each different map_mc have different objects that call the CollisionDetect class. Heres whats happening. objects from frame 1 will start freaking out when I goto frame 2. How do I remove only the event listeners from objects only on frame 1?
I have been trying this.currentFrame but the problem is that all the objects are inside map_mc on the first frame so no matter what it will always be 1. On the other hand MovieClip(root).currentFrame will always give me the current frame but wont tell me what the objects frame is relative to the stage.What I want to do is have something to this effect:MovieClip(root).this.currentFrame would output that this object is on frame 1 and MovieClip(root).currentFrame will tell me that the stage is on frame 2 so I can remove the listeners accordingly.
I've made a parallax scroller consisting of three layers (actually each layer is a movieclip). On the bottom layer I have attached some sprites which I want to be clickable. The problem is that objects which are on the middle and front layer are "blocking" the sprites so they can't be clicked. I've googled for nested listeners but haven't found a solution yet.
View 1 RepliesI have two components in my movie,how to write out the code for the listeners.Is it possible to write one listener that listens for changes in both components or do I have to write a separate listener for each? How would this look like written out?
View 1 RepliesI want to set the scaleX and scaleY of certain child objects within a movieclip, but there are tons of other elements inside of it. Here's what I have so far:
for (var i:uint = 0; i < outer_mc.numChildren; i++) {
trace(' | ' +i+'. name:' + timeline_mc.getChildAt(i).name);
}
This returns 60 child objects. The 50 I want to scale down have "_mc" appended to their instance name. I figure I should make a new array or variable and set the scale of those to whatever I want.

On stage I have 2 objects on stage that share the base-class of "ABaseClass". Each has a child object that shares the base-class of "AnotherBaseClass". They child objects do not share the same parent, and have unique Linkage identifiers of "Object2Design" and "Object1Design", so they should be able to share the same name on the display-list, right? But if these child objects share the same name I get the following error. How to allow child objects to share base-classes and names?

View 8 Repliesin short, i have object A, a container. Within this is object B (a child object) which has some x and Y offset that I input.I need to know the offset of object B, because i want to place other objects at the same onscreen position as B, but on the same level of the heirarchy as object A My problem though, is that B's offset from A isn't changing when i would expect it to - when the parent object is scaled. I set B's x offset to 200 pixels, and no matter how much i scale up or down the parent object, B remains in the same visual position relative to it. And B's x property is still 200, regardless of parent scale.This information is not meaningful to me, because i know that B's actual offset position from A is more or less than 200 onscreen pixels. I need to be able to figure out exactly what it actually is.
View 2 Repliesi have a simple navigation system with three buttons, each button have a text field in it. On mouse over they change color to blue. I can achieve all these without a single line of code. I simply make a button of my text field in flash, and change the color of the text in the timeline.
My problem occurs when i want to make the color to stay blue when i click on the button. Apparently you can't access the child within a button, in my case a dynamic text field. I've googled this problem and they all say that you should use a MC instead of a button. Thats exactly what i have done so far. But i'm getting tired of writing a bunch of eventlisteners and put an extra layer with an invisible button in my button mc so i can get the hand cursor (because the .buttonMode = true and useHandCursor doesn't work when there is text field inside the mc). Any way, shouldn't there be a more elegant way to solve this problem?
I've been trying to build a new base class for my button that extends SimpleButton, and from there access the embedded child object, but the problem remains.

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.
Confused over actionscript children. Reading a book on this shows the following code:

I'm creating a simple drawing application that adds new Shape objects to a MovieClip "canvas" every time the user clicks and drags. The problem is, I'm noticing that even though the MouseEvent listeners are set to the MovieClip, the child Shape objects are being returned as targets as well. This disrupts the localX and localY as well, causing the drawing cursor to jump around as the coordinates change from being local to the entire MovieClip to local to the Shape the mouse is currently over.Is there any way to retrieve the most parental target from a MouseEvent?
View 1 RepliesI use this pattern to test for undefined and null values in ActionScript/Flex :

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?
