I have a document class with a child MovieClip on the stage. I have the clip already on the stage because it's part of an complex layout provided by the designer and it seems easier to leave it on the stage than to use addChild (since I would have to add about 60 objects).What is the best way to reference the document class from inside the child MovieClip class?
View 1 RepliesOk, this is one of those walls that I know once I can jump over it, I will be a much happier developer again.
I've done tons of reading, and think I have a firm understanding that the general consensus is that if you want to reference something, it needs to be added to the display list, using addChild().
I hate to be defiant, but what if I don't want to?
Or at the very least, what if I want to add a movieclip class to the stage using addChild, and then reference objects inside it?
It is much easier this way than what most people recommend - adding 15 objects via addChild, then setting the x and y for the, etc.
That said, I'm all about using classes and using as3 the way it was meant to be used. So what this is, is a best practices question I guess.
HERE ARE THE STEPS I'M TRYING:
- Create new flash document
- Draw graphic symbol bg, with text field over it, select them, convert to movieclip symbol, and export class name "box", then delete it from stage
- Add document class .as file, which simply adds that class "box" from the library, to the display list using a simple addChild()
- Set a name for that box using box.name = "test" let's say
- Do a simple trace like the following - "getChildByName('test').textFieldName" - it shows up great
- So then, I'll now try to set the text by doing this - getChildByName('test').textFieldName.text = "yo";
That last line above, is what doesn't work. I know I'm referencing wrong, but how would a pro as3 developer, reference something on the stage within a movieclip class, from the document class?
I need to increment an integer variable in a function within the document class upon transpiring event in another class. I can't seem to figure out how to call the function and reference the variable.
View 2 RepliesI feel like I should know this by now, but I'm having trouble. I want a function in one of my child functions to increment an integer in its parent function.

The name of my DocumentClass is Main. So, what's the difference between :
var myClass:Main = new Main();
var mcInLibrary:MovieClip ;
/////////////////////////////////////////[code]............
I have a class linked with a movie clip, and in this movie clip I want to be able to add an event listener that calls a function in the Document class (the class you link with the fla as a whole). How can I do that? Say the name of my document class is KPScript.as. In my GameController.as class, I want to listen for key input and call pageChange() in KPScript.as when it gets called. Would I have to import KPScript.as into the GameController.as? If so, I wouldn't want to create another instance of the KPScript object.

View 2 RepliesI'm using a PreLoader as a parent SWF that loads the actual website as a child SWF. In the website SWF, the child SWF, will MovieClip(root) still work and refer to it's own root, or the PreLoader's root? And would I still access the websitite's document class (the child's document class), through MovieClip(root)? What if both files have a document class?So my main question is how do document classes and MovieClip(root) behave in the scenario when you have:
Parent SWF - document class, MovieClip(root)
|
Child SWF (loaded by parent) - document class, MovieClip(root)
here is the scenario we ran across while working on our Flash AS3 project today.
/main/root.fla
/main/root.as
/main/sub1/sub.fla
[code]....
We have many sub swf's that are loaded by the main root swf. The root swf shows the art on the stage of the sub swf, and also runs some code from the sub swf's document class. However, we noticed the constructor was not getting called on the second sub swf if the document class is the same name- even if they are in different folders. Note that we publish our swf files to a separate directory (with the same structure as above) so it is easily copied to the web server.
-root.swf loads sub1/sub.swf
-the constructor of the document class sub.as in subfolder sub1 gets called
-root.swf shows sub1/sub.swf assets with the correctly constructed sub1/sub.as document class
-user chooses to switch to sub2
[code]...
We decided to use a workaround where we basically changed the two document class .as files to be different names (e.g. renamed sub1/sub.as -> sub1/sub1.as and sub2/sub.as -> sub2/sub2.as, and updated the .fla's to point to the renamed document classes), and it works as expected. Hopefully that workaround is useful for someone.I realize most people just name every single file differently and keep everything in one folder, but when you have a sufficiently complicated project, things like this come up.
I am new to AS 3 and I tried to solve this (probably really simple) problem, but I couldn't, so I gotta ask here. All I did was create a child through a function in my document class.It is in fact an altered version of the rotate circles tutorial from kirupa.
Code:
function makeCircle (e:Event):void {
var circle:BlueCircle=new BlueCircle ;

i know this may seem kind of dumb, but how does one access the document class from a child movie clip on the stage?
i have a property in my class. Just a string for testing:
Code:
public var s:String = 'can you see me';
it traces on the root time line, but it errors out if tracing it from a movieclip on the root time line.
I'd like to know how I can reference root stage values from within a movieclip, or even worse, from a class. For example, I have a class called Bground.as. It does stuff, according to current stage size - so if someone were to resize the window/browser, Background updates in real time and does something fancy while it's at it. To do this "fancyness", I need stageheight and stagewidth. However, simply pointing to them does not work.
Here's the simplified ActionScript Code:
package klaseFP{
// imports
import flash.events.*;
import flash.display.*;
public class Bground extends MovieClip{
[Code] .....
TypeError: Error #1009: Cannot access a property or method of a null object reference.
at klaseFP::Bground()
at FullScreen_03_fla::MainTimeline/frame1()
Background works as a document class, works perfectly in fact. However, if I use it as the class of a library object, error 1009 shows up. Same thing happens if I simply put the code into the timeline of the library object - stage referencing simply causes it to break. So, how do I dynamically change the values of variables in Background, according to values in the main movie/app?
Hey guys. It's been a while since I've used Flash and I am still trying to wrap my head around Actionscript 3.0 and the way it works; I am so used to the way AS2 works.I have provided the code below, it's very simple, so you might be able to skip this explanation and just take a look at the error and the code:
- I have made a movieclip called HeroMC in my FLA.
- The HeroMC movieclip has the AS Class linkage of exactly the same name, "HeroMC".
- I have made an actionscript class file, HeroMC.as, to house specific variables for my hero; such as Name, Age, xPos and yPos.
- I have also made an actionscript class file, Main.as, the document class for this FLA.
- In Main.as I instantiate HeroMC using the variable hero, and then run the function addHero() from my constructor.
- addHero() is a simple stage.addChild(hero);
This all works perfectly fine and it adds my hero to the stage. However, the problem arises whenever I try to reference one of the variables from HeroMC.as. I am met with this error - I will use the variable xPos as an example.
Here is the error:
1119: Access of possibly undefined property xPos through a reference with static type HeroMC.
Here is the code for Main.as:
Code:
package {
import flash.display.*;
import flash.events.*;
[code]....
It is obvious this is a very simple problem, but I have searched Google, Kirupa and Flashkit for an answer, but none of the threads I find discuss my specific circumstances and I am unable to find the specific information I need to.
If I have a Document class that extends MovieClip, and I want to use it as the basis for another Document class, is it possible to create a subclass that extends the main document class and use that for a different FLA?
For example,
fla1.fla has a document class of MyMainClass:
public class MyMainClass extends MovieClip
fla2.fla has a document class of MySubClass:
public class MySubClass extends MyMainClass
I've tried, but now I'm getting errors that all of my variables that reference stage instances aren't being found.

View 1 RepliesHow can I run function of the main document class from a class of a MovieClip? I usually just used MovieClip(parent).function(), but now my MovieClip has another parent. Or what do I have to pass to the MovieClip class when creating the MovieClip to acess the main document class?

Going further on my app, I felt in another problem. Despite having lots of posts on the web regarding this, none of the solutions worked for me In my document class (Main.as) ve two containers. One empty and another with a star that is being imported from the library. Here´s the main class:

I am dispatching an event from one document class and listening for it via another document class.My code in class A.

Code:
addEventListener(MyEvent.APERTURE_DONE, onDoorsOpen,true);
trace("Lisetning for APERTURE_DONE");

My listener is registering before the event is dispatched, based on my output window, however I never get the "Open Doors" trace statement to fire.

I have a FLA (say Main.FLA) document class with a child MovieClip on the stage: into the child MovieClip I load other swf files: each of the files contains its own Document Class (every swf is a somewhat independent application, say quizzes and so on).For some reason I must use the Main document class to store data (scores or so) from the child swfs loaded into the Main swf. HOW do I reference the Main class? I can't find a way.[code]and dispatch an Event this way from the loaded swf document class to the Main class:[code]Now, first of all I don't know if this could even work. Secondly, I tried to make it work by adding an event listener to my Main class but id did not work.

I was wondering if it was possible to access the document class from within a movieclip.
I am creating a slideshow type project, and I'm using a document class to switch between the frames using the arrow keys. However, in one of the "slideshow screen" movieclips, I want to have it stop, and then play another part when the arrow key is pressed again.
I tried to access my nextScreenToPlay method within the document class, but whenever I try to do it within a movie clip, I get this error: Call to a possibly undefined method nextScreenToPlay through a reference with static type class.
If I do a trace(Main), within a movieclip, it shows the class.
trace(MovieClip(root).TRACE);
so at pesent I am using this to try and access
Code:
public var TRACE:String
in the the document class.
however I am getting this
"1180: Call to a possibly undefined method addFrameScript.�"
my document class extends to Sprite as I have some stage resizing that occurs on Initialise
Code:
StaticInheritance extends Sprite
Im sure it has something to do with the way the document class extends.
Instead of posting my entire files and such, I'll make a brief example of my situation and my desired outcome. My files consist of my document class entitled Engine.as and another class Abilities.as all within the same folder. On my stage I have a MovieClip with the instance name of item1_mc. On its personal timeline I have 2 frames, one entitled "inactive" and the other "active". Here's a sample of very similar code....
