back_next_nav.alpha = .3;
 
I get the error: 1120: Access of undefined property back_next_nav.

ActionScript 3.0 :: Accessing An Object Drawn On The Stage In One Class From Another Class

Jan 6, 2011

I have created a class, call it Class1, that has various objects drawn on the stage (drawn in the IDE). It also has a function, called setColour, for changing the colour of those objects. The function works fine if I call it from within Class1.

Now I have another class, call it testClass1, that imports Class1 and calls the setColour function. First of all, none of the stage objects from Class1 are visible. Secondly, when setColour tries to modify the colour of an object, I get the error:

TypeError: Error #1009: Cannot access a property or method of a null object reference.

This is the code for testClass1:

ActionScript Code:
package
{
import flash.display.*;

[Code].....

So, what is the problem? Is it possible to change objects that are drawn on the stage of an imported class?

Flash :: Accessing Buttons On Stage From Class?

Feb 7, 2012

I need to set properties of buttons on the main stage from the current class. How would I do this?

I have multiple buttons on my stage. Each representing a chapter in a movie (from frame x to frame y of the movie).

When I push one of them, the movie plays. When it gets to the end, it should continue to the next segment/chapter. This works, but now I need to highlight the current button, not let the button I pressed be highlighted forever..

ActionScript 3.0 :: Accessing An Instance On Stage From Within Another Class?

Jun 14, 2007

access one instance of a MovieClip on the stage (blue_mc) from within the class file of another MovieClip (red_mc).e.g. One instance of "Blue" on the stage called "blue_mc", and one instance of "Red" on the stage called "red_mc". Both symbols are linked to class files (Blue.as and Red.as).In Red.as, I set up a function to listen for a mouse down event. When this is triggered, I want to move the instance blue_mc. At the moment, though, I can't seem to get a reference to blue_mc.I've looked into the new stage and root properties, but even though blue_mc is on the stage, it cannot be accessed using stage.getChildByName( "blue_mc" ) either.

Code for Red.as:

Code:
package {
import flash.display.MovieClip;
import flash.events.MouseEvent;

ActionScript 3.0 :: Accessing Properties From Stage In A Class?

Feb 28, 2012

I am trying to access a property that belongs to the stage, from a class. For example, let's say I add a textfield with an instance name of "magic_txt" on the stage. In the Document Class, I am able to access magic_txt and update the field like so:

magic_txt.text = "Magic Text"

However, since I would like to work in classes, I am having a difficult time figuring out how to access the property "magic_txt.text" from a class. I know I need a reference, but I am unsure how to set this reference.

I am coming from a strong background in Visual Basic, and in Visual Basic, the way to access a form property is to call the form name (dot) object. In actionscript, it doesn't seem to be as simple.

ActionScript 3.0 :: Accessing MovieClip On Stage From Class

Apr 11, 2009

1.I have a MovieClip in the Library. There is a named and dynamic text box in the MovieClip. In Frame 1 of the .fla, I construct the MovieClip from the class StatusBoard and add it to the stage. There is one setStatus method in the class to set the text. This works fine.[code]

2.I have a bunch of buttons that I created from a class called LinkButton.as (they are MovieClips, not _btn buttons). FWIW, they are attached to other MovieClips, but they work fine. The trace output is fine. What I am trying to do is have the rollover change the text in the billboard.[code]

3. In lay terms, I used addChild to add a MovieClip with a dynamic TextField to the stagw and I want MovieClip buttons created from an .as class to be able to change the text on a rollover.What I can't seem to do is actually reference the billboard that I added using addChild from the .fla.The buttons work and trace the desired text, I can't seem to send that text to the billboard.

ActionScript 3.0 :: Accessing Display Object On Stage From Another Class

Jun 8, 2011

I've googled this to no avail, I've only found how to manipulate the stage itself and not a display object on it,I have a movie clip on the main timeline with instance name displayName. I created a button that should change what frame displayName goes to (in order to...did you guess it?! diplay the Name of the button.So I am trying to write the code in a reusable fashion and have the buttons all linked to a class called GeoPuzzle. Inside GeoPuzzle I instantiate a touch event and run the code. However, the function has to be able to change displayName in the main part of the timeline and, of course, the compiler says displayName doesn't exist because I'm in a class and I'm talking about the stage.[code]How can I tell displayName to change it's current frame from within display object class?

ActionScript 3.0 :: Accessing Property Placed On Stage Using External Class?

Apr 23, 2010

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{

ActionScript 3.0 :: Accessing Stage Variables From Class Object

Oct 11, 2010

I was wondering if there is a simple way to access variables from a class object, where the variables are not actually a part of that class. So if you had an array defined on the first frame of the stage, and added some elements to it, you could use the methods of the custom class to manipulate the array's data.

Stage Frame 1
Code:
var myArray:Array = new Array( "apple", "banana", "pear" );
var myClass:someFunctions = new someFunctions();
myClass.addValue( "orange" );
myClass.sortValues();
[Code] .....

It might not seem logical as to why you would ever want to do that, but it's a very simple example, and it's the means I'm after, not the result. I'm creating a list of functions available to execute by a user via an input field. To keep things simple I made them the methods of a class. The issue, however, is that these methods need to manipulate objects which are on the stage, added and removed by a separate controller class. Passing the objects by reference to the class as a parameter would not be viable with what I'm trying to do either.

ActionScript 3.0 :: Accessing Stage Items While Main Class Inheritance?

May 5, 2011

I've made it this way1. I made clip and it's main class (eg. timeline.as) - at this point it works2. I put code from main class to another class (eg. timeline_template.as) and in main class (timeline.as) I inherit it by :public dynamic class timeline extends timeline_template {3. I added stage items declarations in timeline_template.as because without that any code couldn't reach target an I got 1120: Access of undefined property xxx after these steps whole clip works but items on stage ( buttons, etc. ) are not affected by code. That's logical because code references to properties declared in timeline_template but not in timeline.fla. But how to get around that - I need several usage of timeline_template and I would like to avoid code redundancy
