Actionscript 3.0 :: Modify Stage And Movieclips From External Class?
Jan 13, 2009
Still trying to wrap my brain about using classes in as3. I have my document class that calls another class that sets up buttons. I have the buttons working but I want them to play a movieclip on the stage when they are clicked. In AS2 I could just reference _root.mymc.play(); I am also having trouble setting up global variables which I think will have a similar solution. I think I read somewhere that I need to make a 'Globals' class inside my document class. Is this correct? I have tried doing that a few times but keep getting errors.

I would really like a class that i can use to load all my movieclips from.I have 100's of external swfs - and i want to load them to stage from one class - as they are requested.I did manage to do it one way, to get access to the stage i did this:
Actionscript Code:
private var _stage:Stage;
and in the constructor code, just did:[code]...........
how to actually load the swfs, what i'm really looking for is a way to use addChild to the stage from within my class.

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.

ok. so here's the thing..i have a class from where i created an array with the time, name, and position of each movieclip data.. and wanted it to go through each one and execute at a certain time.. So i tried something like this:
[Code]...
the first part works well.. but its when i try and add it to the stage that i get confused.. i tried something but i think its wrong.. can anyone help me? Basicly i want flash to get the array.. use index 1 for the name.. index 2 for the x position and index 3 for the y position.. but all this name referencing in as3 really confuses me.

Is there any way to move or scale a bunch of movieclips on the stage as one, without putting them inside of another movieclip?

1) I created a movieclip (book_mc) on the stage. Inside the book is another movieclip (bookPages_mc). Inside of bookPages_mc is a third movieclip (subNav_mc).
2) On the root layer I created another movieclip (button).
3) On "button" I went to Linkage and gave it a base class of my own creation, "MainNav".
Now in the MainNav class I want to tell the subnavigation movieclip to animate.
The problem is - I can't figure out how to reference nested movie clips from an external class.
(For the record - everything has an instance name and has been double checked. The code works from within the FLA but not from an external class.)
Here is my class code (everything works except for the reference to the nested movieclip):
Code:
package {
//imports
import flash.display.MovieClip;
import flash.display.DisplayObject;

I'm having problems referencing the stage from an external class. I've tried :
Code:
stage.addEventListener(MouseEvent.MOUSE_UP, onUp, false,0,true);
And also
Code:
MovieClip(parent).addEventListener(MouseEvent.MOUSE_DOWN, onDown, false,0,true);
But no luck. Can I not do this? I'm making a pencil class that I want to be able to reuse. I also tried "this" and while it didn't throw and error, it didn't work either.

When I debug this, it gives me an error saying that it cannot access the stage because it's a null property.

I'm trying to create an application with an extensive user interface. I've come pretty far and decided I wanted to really take advantage of the object oriented features that AS3 has to offer.
I've started off by created a few classes: User, Background and Main. Main is the document class of course. In the document class I have a function "resetStage" that clears the display list of all children. This is because I have many layers of images making up the UI and they all show up at startup unless I remove them. Besides I want to see where the stuff is positioned in the Authoring tool so I don't want to just create movieclips and then delete them.
My issue is with my Background class. Basically what I want to do is create a new DisplayObjectConatiner called bgContainer or something and then put all the background stuff in it. (The main background image and a status bar image). Then add the bgContainer and its children to the stage. This should all happen when the object is constructed.
Main .as
---------------------
package
{
public class Main extends MovieClip
{

How can I access objects and modify their property that is ALREADY placed on the stage using external classes (AS file)? I 'm a newbie of AS3 and followed some tutorials about AS3 not long ago. For I learned scripting in AS3 can be done using AS file rather than script on Timeline. But I have a question. How can I "find" and "modify"the objects on the stage, or inside a MovieClip , in AS3?
For example, I have a file call Stage004.fla which have no document class linkage. I place the MovieClip "StageMain" which links the Stage004.as on the stage. StageMain has a textfield in it named "textFieldStage001". The Stage004.as is ran using "Event.ADDED_TO_STAGE" since StageMain is on the stage. I create another AS file WindowRename , to test can I modify the text in "textFieldStage001".
Then the famous error #1109 occurred.
"1119: Access of possibly undefined property textFieldStage001 through a reference with static type Class."
ActionScript Code:
package {
import flash.display.Stage;
import flash.events.Event;
import flash.events.MouseEvent;
import flash.display.MovieClip;
public class Stage004 extends MovieClip{

I have a media player that I am codging together, one that will play either videos or MP3s depending on the variables it is passed. The video player part works fine. The MP3 player controls are all actual physical MCs on the stage; each one has its own AS class file as part of the package, but there is also a lot of AS that is happening in the main FLA as well. Messy, I know, but it mostly works great.
The MC on the stage in the main FLA is properly linked to the class file via Actionscript linkage, and the control itself works. However, I am trying to make some aspects of the control respond to variables that are set within the AS on the timeline of the main FLA, and I cannot seem to pass values to the control no matter what I do.

I'd like to draw a furniture in Flash in actionscript. Actually It has done. My problem is the horizon point of the stage. The acceptable figure of the furniture is at that point where it hangs out from the stage. (size of the stage is 1024x768 and this point is 700, 600 so the furniure isn't in the centre of the stage.)
It's occured because flash draws for example a cube in the centre of the stage. So my question is that I can modify the horizon point of the stage - for example to the 0,0 point, because It would be the best for me - or not?

I have a dynamic textfield called neighName on my Flash stage. I also have a movieclip that I call a region on my stage. When I mouseover the region, I want a word to display in a little popup *and* I want some text to display in my textfield. I have an external .as file for handling the region. I can make the code "see" my region, but I can't seem to make it see my textfield, although no errors are being thrown.

I am trying to get an instance of a class to the load an external swf and show it.So far I have the following:
1) I wrote a class that uses the Loader class to load an external swf "loadExtSWF".
2) I have a fla named "MainSWF.fla" that uses a document class "MainSWF.as".
3) I have the MainSWF.as file that instances "loadExtSWF" and calls loadExtSWF.startLoad to load the swf.
This almost works. The instance of loadExtSWF loads the external swf, but the swf is not displayed.If I replace the fla's document class with loadExtSWF (this has an empty constructor) instead of MainSWF, and run loadExtSWF.startLoad, then the external swf is loaded and displayed.[code]

Here is my problem (unfortunatelly didn't find solution @google):I'm loading external swf[AS2] into main swf[AS3] using Loader class. The main swf is 800 x 600 and the external swf is 300 x 200.After adding the external swf to the main swf the external swf expands it's size from 300 x 200 to the main swf's size: 800 x 600.

I've been searching around all afternoon, and am pulling my hair out. 1) I have a movieclip instance on stage (simple graphical element that represents platforms for a hero to run and jump along). I have placed it on the stage with an external class engine.as and in this class it is called myPlatform and is an object of Platforms.as. The movieClip is called platforms and from a trace(myPlatform.name) the instance name is instance3.
2) I am attempting to access the properties of myPlatform in an Enterframe event loop in my character control and collision class (called hero.as)
Basically here is the bit of code I am trying implement within Hero.as :
[Code]...
This all worked when I was writing actionscipt within the FLA file, on the timeline frame 1. I simply don't know how to access myPlatform from within the external Hero.as class! Do I need to create a variable? Is there a really easy way to do this with some syntax/command that I have not learned yet?

I have a preloader that i found on the net which i am using to load my main .swf. Inside the main .swf I am loading several external .swf's and I wanted to use the same preloader to load them in.. however I am having a bit of trouble doing so.. here is the code that is attached to the preloader I am using..
Code:
onClipEvent (load) { total = _root.getBytesTotal();}onClipEvent (enterFrame) { loaded = _root.getBytesLoaded(); percent = int(loaded/total*100); text = " "+percent+"%"; gotoAndStop(percent); if (loaded == total) { _root.gotoAndPlay(2); }}
When i use this preloader inside an external .swf which I am pulling into my main movie it resets the whole movie back to the begining.. i guess because of the referals to _root in the code...how I should modify this code for the preloaders in my external .swf's so I can preload and then play my exyternal .swf's in my main movie.
