I`m having a silly problem with adding instance of an object to the stage two or more times. For example, this don`t work:
Code:
var temp0:SomeClass = new SomeClass();
this.addChild(temp0);
this.addChild(temp0);
Well, I know that one instance is one instance and two objects of the same class on the stage would be two instances, but still, it is what I need.
I know this is one of the most basic things, but I am having trouble adding an instance of a symbol to the stage with action script in Flash CS4. I have a "fireball" symbol and at the beginning of my code I say:
var myFireball:MovieClip = new fireball;
addChild(myFireball);
But it says : "1180: Call to a possibly undefined method fireball."
I have created a movie clip on the stage and in symbol properties I have checked "Export for ActionScrip" the MC name is "slide" and the class is "slide" base class is flash.display.MovieClip.
When I test the movie I get this error.
TypeError: Error #1009: Cannot access a property or method of a null object reference.
at main_fla::MainTimeline/frame1()
Here is my code:
PHP Code:
var slide = getChildByName("slide"); //add instance from library?
function slideRollOver(event:MouseEvent):void {
// trace("OK");
} slide.addEventListener(MouseEvent.ROLL_OVER, slideRollOver);
I created four instance of movieclip on stage and named them t1_mc,t2_mc,t3_mc,t4_mc. Then I made and array and loaded them inside the array
var arr1:Array = new Array( t1_mc, t2_mc, t3_mc, t4_mc );
var names:String;
//function made to add event listener to each object
function addListner():void {
for ( var i:uint = 0; i < arr1.length; i++ )

I've been working on an as3 project for quite some time now, but I can't seem to get the following code working for some reason:
Code:
var test1:Object = new Object;
stage.addChild(test1);
I keep getting the same error:
Implicit coercion of a value with Static Type Object to a possibly unrelated type flash.display: DisplayObject
I want to add a key listener to my stage, but from an object 2 depths below the stage. How would I do this? I thought about adding the listener from my doc class, but the listener function is in the object that is two depths below the stage, which would mean I would have to pass the key values to the next movie clip, then when that one is loaded, pass it to the one with the listener function. It seems very complicated, is there an easier way which keeps with the principle of OOP?
View 5 RepliesDoes creating a new instance of an Object that uses an identical name to an older instance, delete the previous instance? Or should the original instance be deleted first? The code uses a ridiculous amount of XML vars. Isn't it less memory intensive to parse the XML and save the properties to an Object, and then delete the XML Object, rather than keep the XML Object around and reference it's child nodes directly? Is it better form to break up a huge XML file (>600lines/3200vars) into smaller chunks?
View 1 RepliesI have a library object (SomethingMC) which extends a custom class (Something). Something, in turn, extends MovieClip.If adding SomethingMC to the stage within Flash CS3 IDE, is it possible for it's super class (Something) to assign an instance name from a class constant (Something.THE_CONSTANT)?
package
{
import flash.display.MovieClip;[code].....
The above does not work. It throws Error #2078: The name property of a Timeline-placed object cannot be modified. if the instance is assigned a name in the IDE, and it just doesn't work if no name is assigned in the IDE.
I am wrapping my brain around OOP in AS2. I am making two posts on two different subjects. My question here is: when should I use local instance variables, and when should I attach new properties to the instance object? (Feel free to correct my terminology.) Let's say I have a class for a scrolling background, which scrolls when I mouse over its edge. I want to put these values somewhere:
1) How wide is the border in which a mouseOver makes it scroll? This is basically a semi-constant I set it up once and keep it the same, unless the user changes it in an options menu to make the border wider or narrower. Call this scrollBorderWidth.
2) How fast is the background scrolling now? I want to track this so I can smoothly change the scroll speed over several frames. This is often changed. Call this scrollSpeed.
It seems I have two ways I can store and access these values and darned if I know which is better practice. METHOD A: Make them local variables in the class, so the scrolling background instance has them as local vars. I set them up thusly:

I would like to know if there is a reason that, within an AS3 class, I would want to do something like this:
var myStageInstance:Stage;
//within an arbitrary class
var myStageInstance:Stage = stage;
myStageInstance.addEventListener(MouseEvent, someFunction);
as opposed to something that I would normally do:
//within an arbitrary class
stage.addEventListener(MouseEvent, someFunction);
There is no particular problem that I am looking to solve right now. I would just like to know if there is a reason to use one method over the other.
I want to add a new instance of a MovieClip named chair_mc in my .as file but am not sure where to place it. I also want to bring in two other MovieClip symbols but am not sure where to place this. This is the code:

When addressing nested movieclips like so: _root.movieclip.movieclip.variable they need to have an instance name set, otherwise they count as undefined. So I can set that in the properties no problem, but when deleting it from the stage and then readding (manually or by actionscript) the instance name is gone thus I can not address nested clips by action script.
I don't understand how this will work then, since every time I add a clip by code it will have no instance name. The only alternative for me so far was keeping the clip on the stage the whole time, just out of bounds or invisible so I can still do stuff like _root.movieclip.movieclip.variable or _root.movieclip.movieclip.gotoAndStop(2).
i have a preexisting instance known as gamelevel. When the screen scrolls, gamelevel.x is modified. When the player shoots a projectile, this projectile is not moved along with the screen, because it is simply added using the addChild. How can i add the movieclip, but have it contained within the gamelevel instance?

View 5 RepliesMy name is Bryan i am 17 years old and i'm from the Netherlands. As i am trying to become a web design and developer i decided flash was a MUST to know, so i started trying flash and messing about. Now i'm trying to get into Action script 3.0 deeper. Currently i am trying to fix an externaly (XML) loaded image gallery for my self, except i'm a little stuck right now.Up to now all my code has worked. I've got 3 UILoaders set up for 2 jobs: Loading thumbnails (2 of them) and the other is for loading a 'full' version. I got that working. Except if i get huge images like a wallpaper etc. it screws up the size, so i set scaleContent to true.
- Set all the images dynamicly, with that i mean it loops trough all the thumbnails and gets the first 2, it dumps them into the UILoader wich is already the part i am failing at XD
- Check for the width and the height of the image (wich i either will include in the XML document or can i use something like: XMLData.image[ *number here* ].img_thumb.width (as a example)?
- Check if these are less than the UILoader's size and if they are less dissable scale content, if they are more enable it
So as i said im already failing at trying to dump the images in the thumbnails.I've got the following setup:
Root document has a MC: mc_content.
Inside mc_content we have: loader_image (full size of the image loader)
loader_thumb1 and loader_thumb2.
So what i want:
- Load the XML (works)
- Set some limits using variables (works)
- Start a for loop (works)
- get the thumbnail for the current image number (wich is a variable set and maintained in the for loop) (works)
- load the image into the loader_thumb *insert current image number here* (fails)
here is my current XML function:
ActionScript Code:
// Function that is called upon loaded complete
function xmlLoaded(event:Event):void{
// get the XML Data from the file

Is it possible to add a textField dynamically but have different instance name each time this is created? In other words if I have a button that whenever its click it will add a textField to the stage and assigns a new instance each time this is added.

var inputWidth = 200;
var inputHeight = 20;

I have a third party slideshow instance (SlideShowPro (SSP)) and have used the following code to allow SSP to resize to screen:
import net.slideshowpro.slideshowpro.*;
import flashx.textLayout.formats.BlockProgression;
stage.align = StageAlign.TOP_LEFT;

It all works fine. However, I am trying to put in links on the stage outside of SSP (i.e., Home, Gallery, About, etc.) as shown in this example website [URL]. When I do, the stage is truncated and part of SSP is skewed off the page.
How do I make sure that my stage containing text and SSP is captured as the SWF?

The Sample object does get added to the stage, although it doesn't honor the x & y position I specify. I'm sure I'm failing to comprehend something simple,
figure out why the movie i just made is off stage. I just I don't want to start from scratch or move every object that is off stage onto stage. What did i do to get it here to begin with???
View 1 RepliesI have a stage bigger than the size of a browser, and I have a camera to navigate around the area.Now when I click on a button, I will have something pop up blocking the whole browser, like a lightbox effect with another box on top of the blocker.The problem now is, when the blocker pops up, its position is not on the TOP LEFT corner of the browser. I've tried stage.align, but it would makes the camera or other object on stage position run.So is there any other way I could get the blocker to position according to the browser, not the stage?[code]
View 1 RepliesI have one MC on stage with instance name "box". That MC duplicates by using this script:
Code:
duplicateMovieClip (box, newname="box2", this.getNextHighestDepth());
box2._x = xPoz;
box2._y = yPoz;
So the new MC is now called "box2".
Inside original MC "box", I have one button. After click on that button, I need to know on which MC I clicked. box, or box2. I tried to use:
Code:
trace (this._name);
But, that get me only instance name of the button.
I was just doing a menu system for a game project, as3 with Flash CS5. The navigation is build on the frame on the main timeline. When I was creating stuffs on the 3rd frame, the btns on the frame can not be called, returning "null", this is weird. With further study, I found that, if I delete a instance on frame 2, the problem on frame 3 will be solved. Then I found that giving the instance on frame 2 a name could also make things normal. What is happening? Why having a unnamed instanced on the previous frame could make the instances on the next frame "null"?
View 2 RepliesI'm using Flash CS5. I have some instances on my stage declared in the main class and I want to attach some events to them, however at the time of the main class constructor, these are declared as null.
What's the best practice for accessing stage instances? Is there an event listener I could add that will tell me when the stage instance properties have been populated?
Simple example:
public class bleepBloop extends MovieClip {
public var productName:TLFTextField;
public function bleepBloop() {
trace( productName ); // Here it is null
}
}
However, when I access productName later, it's defined.
How can I refer to an instance on the stage if:
- I added it to the stage using the GUI
- I wrote its implementation in an external AS file
I can't assign it a instance name otherwise I get this error: Code: ReferenceError: Error #1056: Cannot create property myInstance on MyClassName.
