Flash :: Access The Stage?
Oct 10, 2010I'm trying to get a projector file to run full screen when it starts, without needing to click anything. My main class inherits from MovieClip, so as far as I can tell I get access to stage..

I'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.
This may be a stupid questions but I can't find it.I'd like to refer to movieClip onStage by looping though it for example, I have 10 movieclips name slot1 - slot12 then in my code
var hole:MovieClip;
function checkHit():void {
hole = pirate.slot3; // My problem is here how do i change this slot3 to slot 4,5,6 ...

I have encountered a problem when I need to load a third-party flash in to my flash. The flash is written in an erroneous way, it access stage in the main class constructor. I know that a display object can not access to stage property until it is added to stage, and certainly can not access to stage in its main class constructor. I observe 2 cases:
- If the flash run STANDALONE, it run well: I don't know why stage is assign before its constructor
- If the flash is LOADED by my flash, it yield null reference exception as expected
In the second case, if the third-party class remain unchanged, is there a workaround that load flash?
Access stage objects (like Movie Clip or text fields) from sub classes.The problem came when I define a subclass and try to access stage objects. How can I do that?Imagine I have a movie clip named redBox_mc on the stage.I want to change it`s alpha after I get my xml loaded.(or any other action in subclass)
Main class:
package src{
// ..
public class code01 extends MovieClip {
public var rt:xmlReader = new xmlReader("art.xml"); // my subclass

I have an object on my stage, called obj.I also have a class called "Physics" which contains a bunch of methods for physics, such as inertia, gravity, and bouncing off walls. In order to do some of these,I need access to the stage.stageWidth and stageHeight properties.My code is as follows:
public function wallBounce(obj)
{
this.stageRef = stageRef[code]...
This is supposed to check if the object's x value is greater than the stageWidth or less than 0. When I run this code it says:
TypeError: Error #1009: Cannot access a property or method of a null object reference.
I am a semi-newbie programmer who is completely self-taught and have no clue what is causing this. I spent a bit googling it, and I think it has something to do with scopes,.
Say I've got a utility class in which I would like to access the stage (in order to get the frameRate).
I don't particularly want to force the user to pass in the stage to each method or set a static property on my class before using it.
Is there any way to get ahold of the stage without it being passed in? All I need is the frameRate!
If I have a swf that's being loaded into other peoples' swfs (which I have no control over) is there any way I can get properties from the stage (such as height, width, fullScreenHeight, etc.) or does this have to be exposed by the loading swf?
View 1 RepliesI have a "box_mc" movieclip on the root of my stage and I need to select it from within my Document Class. I thought Stage.getChildByName("box_mc") would work, but it just returns null.
View 2 RepliesThe problem I've encountered is that I am using a keyboardEventListener to make a movieclip run around. As I'm a college student, I'm creating this for an assignment but we are forced to use as3 classes.
When I run the code in the maintimeline, there is no problem. But when I try to access it from another class (with an 'Export for ActionScript' on the movieclip in question) I get an error he can't address the stage.
this.stage.addEventListener(KeyboardEvent.KEY_DOWN, dostuff);
I can access the targetObj instance inside the document class, but when I try to access it in another .as class,get this error:
Access of undefined property targetObj.
I am trying to add a keyboard event listener to the stage, to detect when a user clicks the left or right arrow keys. But this listener is called from inside a class file which is imported into the document class, therefore I think it doesn't know what "stage" refers to. How do I solve this?

So, can I access layers on this MainTimeline to get all Movie Clips on this layer ? So I can do a simple operation "A_1_2.buttonMode = true;" to all my MC's (in an array for example) without writing every line (lot of MC's on layer and lot of lines).
I added a graphic to the stage and I need to access it from actionscript
View 1 RepliesI have created a game in flash, and due to the nature of the game, I have many movieclips placed on the stage manually in Flash CS4. They are not programmatically added as children to the stage, and so I am having difficulty getting access to them in the document class. So far the only method I have been able to use is to do stage.addChild(active_area); (for example), but there are many movie clips, all very differently named, so this method seems incorrect.I've discovered that my MovieClips are not children of the stage, but in fact MainTimeline, as when I for loop through stage.getChildAt(i);, only one child, root1, is traced out. How can I access movieclips that were placed on the stage in the timeline from the document class, without having to manually add them as children to the stage? So it looks like my problem wasn't that I couldn't access the MovieClips, it was that I wasn't modifying the MovieClips' values, so I wasn't registering any change in them.
Here is the code after I fixed it:
function manage_cursor(e:Event):void {
prevX=currX;

I am confronted with a simply yet annoying problem: I manually created a row of MovieClips inside another movieclip container_mc on the stage in the Flash CS4 Editor. The MovieClips are named in the same convention (eg. target_1_mc, target_2_mc, ...target_200_mc).
When I try to access a property of it via AS3 during runtime of the SWF like this, it works:
container_mc.target_0_mc.alpha = 0; But how do I access the MovieClip dynamically? During runtime, a script will determine of which MovieClip i need to access a property. I will get the ID number of the MovieClip I want to access. So I need to be able to to something like this:
var mc_ID:int = 2; ["container_mc.target_"+mc_ID+_mc""].alpha = 0;
Obviously, that doesn't work. When I would create all the target-MovieClips dynamically at runtime, I would simply put them in an array. But in this case I need to work with the existing MovieClips manually created in the Flash Editor.
Base extends MovieClip document class extends Base how would Base properly access a display object which is already placed on stage in the flash ide? for example creating the var in Base's class definition = 1152: A conflict exists with inherited definition in name space public. but just referencing the var = 1120 undefined property , as the item is only a variable of the document class Is the only approach to let the classes load, then create the display object rather than have it on stage already?

View 4 RepliesI have a CustomSimpleButton class and a CustomSprite class which creates a bunch of CustomSimpleButtons and displays them at runtime. How can I access other objects on the stage in Flash inside of my two custom classes? If I want an object tween to occur when one of my custom buttons is clicked how do i reference the object that I want to tween if I'm inside of my custom class.
View 0 RepliesAs stupid as my question might sound, i have spent the last 2 weeks reading oop books; but could use some guidance. I have a flash project that is basically a supped up slide show. On the stage i have the following: main_mc (instance name = images_mc) = movieclip which holds "pictures" ui1 (instance name = ui1_mc) = user interface that allows user to draw on picture (when drawing is enabled) ui2 (instance name = ui2_mc) = activates invisible hit areas (buttons) on select pics, when hit area is clicked, we jump to another pic in the main_mc.
I accomplished all of this on the timeline, but am updating the code to OOP. I am having A HELL OF A TIME trying to figure out how to store references to the instances (images_mc etc..), so i can control them from varying class files. I have found it is easy to control the instances from the documentclass, but not from unrelated class files. Example: images_mc.stop(); works in document class; but ovieclip(Parent).images_mc.stop() doesn't seem to work from any class file.(ui2 class file for example);

what I'm trying to do is accessingsnapText = scrollPane.source.textSnapshot;from an external swf. I've tried:
trace("-->: "+scrollPane.source.textSnapshot.getText(0, 1000));
trace("-->: "+myLoader.content.textSnapshot.getText(0, 1000));
trace("-->: "+mc.textSnapshot.getText(0, 1000));

I've embedded a MovieClip symbol with the [Embed] syntax into my AS3 project, which I'm compiling with the Flex 3 SDK. That MovieClip has instances of other clips within it that are placed on stage with instance names. I can't just access them by instance name like I would if I were compiling with the Flash IDE. How can I reference them?
View 1 RepliesThere is a movieclip ("abc_Mc") on stage. I know, to access it, i can simply use Document class, and add a variable named abc_Mc and thus can access it.
But i wanna access it via stage property. ( As it must be a child of stage)
I added a movieclip "a_Mc" on authoring time, and used the following code :
import flash.display.MovieClip;
for ( var i = 0 ; i<stage.numChildren ; i++)
{
var a = stage.getChildByName("a_Mc")

I am not getting the value of that movieclip
I have 54 MC's on stage, generated dynamically. Now I want to get their x and y positions when rolling over but I am having problems getting the path correct e.g.[code]...
View 2 RepliesI have a MC, instance name "jez_mc" this is inside an MC, instance name "container_mc". container_mc on on the stage.I then have an MC dynamically added to the stage. In this MCs timeline I want to access a variable stored in the class that is linked to jez_mc. This var that I want is named "score"So i figured in my timeline I could use something like:
var _jez_mc:MovieClip;
_jez_mc = MovieClip(root).container_mc.jez_mc;
trace("_jez_mc.score");

I understand the reason for the error is because I'm trying to access the "Stage" when I'm not at my Document Root. The question I have it how do I do this same thing when I'm not at the Document Root?
I'm having an issue accessing items on the stage from some imported code. I found this topic that discusses the same issue... [URL]
I'm not sure I totally understand how to go about this. I don't understand how to make the object global so I can access it from any class. (I have the same problem with an array I'm working with).
I have:Stage -> SWF Loader Root -> SWF Loader -> MovieClip -> Nested MC.From within "Nested MC": I can only access "SWF loaders root" time line, I can't seem to get access to the stage's functions..[code]Im trying to call on a function which resides on the main time line.Is there any way to access the main timeline?
