ActionScript 3.0 :: Symbol Disappearing In Component When Instantiated?
Mar 4, 2010
I've created an AlertBox component by doing the following:1) Create new fla fil2) Create shape and convert to movieclip on stage3) Name new movieclip AlertBox in movieclip properties4) Add custom class path in Properties -> Linkage dialog box and Component Definition dialog box:com.company.ui.AlertBox;4) Checked export in first frame box5) To test this stage: Export as SWC file6) Place SWC in components directory7) Create new test fla file

I have a mc in my library called SimpleButton and in the class path for that mc I have the path to my class: com.company.ui.buttons.SimpleButton.
But when I try to instantiate the symbol using the following code, it does not appear on the stage.
Code:
var simpleButton = new SimpleButton();
addChild(simpleButton);
The code works fine when the mc class path is just SimpleButton, the symbol is added to the stage. However when I try to use my own class, the base class disappears from the linkage box in the mc properties dialog and the symbol does not appear on the stage.
Here is my SimpleButton class:
Code:
package com.company.ui.buttons
{
import flash.display.DisplayObject;

I have built a component, but the assets do not appear in the symbol library of the destination fla when I drag the component to the stage. This is fine, except that I have embedded a font in the component. To ensure the font exists in the destination swf, it must exist in the symbol library of the destination fla.My component extends the UIComponent class, and I have a component shim, although I'm still not entirely sure of its functionI have followed all of the steps found in the 9 part MenuBar tutorial, and everything works, except for this one issue.

I tried installing Flex_Skins_12_05.mxp that suppose to enable these features in flash cs4 but under the commands tab i can't see any commands related to flex conversion.

I usually use if(object!=null) but it doesn't work well.
How can I verify if the class is instantiated. I want to get rid of the 'cannot access a property of a null object or reference'.
I mean, the 'var object:Object;' is just a reference to an Object class instance. When i initialize it with 'object = new Object()' it runs the code in the constructor, initializing it. How can I check if it has been initialized or not.

I've been struggling with this for almost a day now and I can't seem to find the problem. I'm making an instantiated FLV playback class in actionscript 2, but it just doesn't play the video
Here's the code, if I uncomment the camera parts and attach _cam instead of _stream it will show the camera feed, it just won't play my movie (and I get no errors whatsoever).

I have a project in Flash Professional CS5 and ActionScript 3.
I have a movieclip symbol (referred herein as "background" with scripts on various keyframes inside of that symbol. I need to hide or show another symbol (referred herein as "object") sharing a stage with "background".
To put it another way, I need "object" to be hidden when "background" reaches a certain internal keyframe. However, as "object" and "background" are both children of the same stage, how do I do this?

what i want to do is, when certain button is clicked, replace a certain symbol(button) by another symbol(movieclip) stored in the library. i try things like loadmovie("","") to replace the symbol from a external jpg, but some how it does not align even both images are exact dimension. can i replace an image straight from the library?

I wanted to instantiate a class that would render a sprite, but it doesn't seem to want to add the graphics to my stage.
Here's the main class, it creates an instance of 'Canvas' which would basically be a gray square rectangle that fills the stage width/height.
Code:
package
{
import com.webkitstudio.Canvas;
import flash.display.Sprite;
[Code].....
I had more success rendering the gray box if i make a method in the Canvas class that renders it, but is it possible to do it from the constructor, is that even advisable? I'm somewhat an OOP noob, i don't completely understand where everything should go.

I'm facing problem regarding dynamic texts. My dynamic text is placed on the stage and instantiated. I'm setting the text value in AS by using textname.text = smthing... Initially it was showing the correct result on testing the movie clip.. But after few runs it started showing garbage values... When i traced the value, trace showed the correct result but not displayed properly on the dynamic text..I then deleted and recreated the texts.. After some trials od deleting and reinserting it started working fine.. But soon the problem creeped in.

I have this class called Main. And inside this Main class I have a method that I'd like to call from a the main timeline.
So on the main timeline I have instatiate the Main class like this:
var mainClass:Class = flash.utils.getDefinitionByName("Main") as Class;
var main:Sprite = new mainClass(this, mc1_mc, mc2_mc);
addChild(main);
Then on the frame after that, I try to access a function inside that Class like this:
main.prepareGame();
But I get this error:
Scene 1, Layer 'Layer 2', Frame 3, Line 61061: Call to a possibly undefined method prepareGame through a reference with static type flash.display:Sprite.

I'm very confused. When I instantiate a class, I'm assuming that the object is reset to its default variable values. Not so. Consider this:
Code:
class ClassTest extends MovieClip{
var arr:Array = new Array();
function ClassTest(){
[Code].....
...even if the two objects have different instance names! It's as if it is making my arr variable static by default, and not resetting it to a new array in the second instance. How do I get around this? Do I need to somehow have this code instantiate itself with something like "this = new ClassTest();"

h1. I have a Class (let's call it "Button") that is linked to a library item (a movieclip) which I have on the stage
2. Now this Button class, when clicked will produce an alert in the form of another class (let's call it "Alert").
3. There are two critical things in the way I want this to work:
A) I want Alert to be a child of the main stage, not the Button class
B) I want Alert to take care of adding itself to the display list, not have Button add it.
So in a nutshell, I want to call Alert like this:new Alert("Hello, Kirupa Forums!");
The Alert class needs to draw the shape (check), add the text (check), add itself to the display list (how? if I try to access "stage" I get a null reference, though I don't know why), and destroy itself (I'll burn that bridge when I get to it).

What I'd like to do is add an event listener to a class instantiated by my document class that listens for different key presses. So far I can't use stage.addeventListener or I get the null object error so my question is:
a: how do i add an event listener to the stage from another class and b: is it even necessary to add it to the stage , can I listen from that class?

Basically there's an object in a movieclip. I want to find the location of that object in relation to the movieclip, not of the object's symbol. So when i look at the x and y of it, it wont show 0, it will show the x and y location in the movieclip it's in.

I have a simple component I created which I instantiate in my main program like so:[code]I receive the error "Cannot access a property or method of a null object reference" on the second line because newMessage was not fully created prior to hitting the second line of code trying to set my "body" textarea's text. I know I can build a "creationComplete" event handler, but isn't there a simpler way to do this?

I have an XML file which has info about projects for my portfolio, there are 7 of them at the moment. I'm trying to have a preloader animation show up in place of every portfolio image before it's shown on stage. The problem is that there are 14 of those preloaders being instantiated rather than 7!! How could that be possible? Check out my code:
