ActionScript 3.0 :: "Unable To Access Stage From Another Class"
Dec 13, 2009
I'm porting a Tetris game I created in Javascript to Actionscript to get a little Flash/AS experience.
I have my main flash file, TetrisMain.fla and TetrisMain.asI put the main background image of the playing field onto the stage here. It displays correctly.
I have a file called TetrisBoard.as ( keeps track of score, level, current row etc)
I have a file called Tetraminoes.as
I inserted a "block" jpg into the library. I inserted a movie clip "Block" into the library, and dragged the block.jpg onto it. When a new Tetraminoe is created in the constructor, it creates "new blocks" which are the tetraminoe blocks. [code]...
xml_object.childNodes.length will return the number of childnodes there are. But I don't see a way to get at the number of childnodes of a particular type. This will not tell me, for example, how many childnodes of type "b" that "a" has. I can't see Flash XML support being this sparse. Is there a built-in way of accessing the nth child of a node of a particular element name or am I stuck with accessing it only by number.
i wonder why i am unable to access the public properties of this custom class the public var w:Number; and the Public var h:Number; i am tracing them and on an instance of the PreLoader() Class.. and ia m getting NAN;
I will be choosing which mask to use based on users selection of puzzle piece.When I try to use traingular mask by adding puzzle.gotoAndStop(2) the swf just flickers. Thought the holder_mc and mask_mc are exactly of same dimension one comes below lower than other though I have not altered the position of the clips within a puzzle piece.If you want to take a look at my fla here it is https:[url]....How to go to a specific frame 2. Why is position of two clips inside the piece changing
How to access a display object on the stage in a class which is not a document class?
I am looking for a solution that doesn't involve passing the stage as a parameter to the class.
One solution i always come across is using "TopLevel.as". Is it a good method because as far as I have heard using global variables is not recommended because it might cause some problems while working on big projects.
I was wondering how do you access the stage property from a different class that's not the principal class tied to the fla? Essentially, I have main.as which calls another class menu.as, and I can't seem to be able to use the stage.stageWidth property from menu.as. What's the proper way to be able to use the stage property from any class? Do I have to import it separately each time?
I 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'm trying to access a MovieClip created within the authoring tool from an ActionScript class. Here is my code:
PHP Code:
package { import flash.display.*; public class MoreVideos extends Sprite {
[Code].....
I also tried changing that to [stage.moreVideosBox.visible = false;], but I then got "1119: Access of possibly undefined property moreVideosBox through a reference with static type flash.display:Stage."
Is it possible to directly alter items in the authoring tool from a class? If I move 'moreVideosBox.visible = false;' outside of the class, in the main .as file, it works fine.
This is for AIR: My document class imports a separate class "ConnMonitor" and uses it to constantly monitor the network connection. It's at the very end of that class where it's supposed to update a textfield on the stage as the connection changes, but the class can't access the textfield.
public class MyClass extends MovieClip { public function MyClass():void { my_mc.addEventListener(MouseEvent.CLICK, action); } private function action(e:MouseEvent):void {
[Code]...
I can't able to access the my_mc(placed in FLA) movieclip. How do I access?
I have a document class called Main, and a class called DispatchEventExample. In DispatchEventExample, I'm trying to add an event listener to the stage but get an 1120 error, access of undefined property stage.
If I understand things correctly, even though I create an instance of DispatchEventExample in Main, it's not added to the display list & therefore cannot access stage.
I need a class code to access a child instance of another class code that is on the stage. I have a class code named Ball.as. On the Time Line is a child of the Thing class. It is call newThing. Here is the code in the Ball.as file:
I've created a custom class (not the document class, otherwise there would be no problem) and I want to be able to access a MovieClip that is sitting on the stage.
How? MovieClip(parent), MovieClip(root)... don't work. What's the proper procedure?
Also, can I pass the MovieClip from the Document Class to another custom Class?
Just tried using cs5 on my new macbook and I have a tlf text object on the stage with an instance name of mText. I tried to access (mText.text = "test") it like this and got a null object reference. I tried to trace the stage from my document class and it was null when the tlftextbox was on the stage but i could trace stage correctly when I deleted the textbox. [code]...
I have a class that have a method to do some work and return a MovieClip. How can I access the stage from the class ? I don't add the class object to stage.
My code is like this :
Code: import com.ClassName . . . var c:ClassName= new ClassName(); var mc:MovieClip; mc = ClassName.create("some parameter");
I want to get access to the stage from ClassName class file.
I m trying to access stage.width property but sometimes it trace 650 and 720 but i see my flash file dimension is 500x400, I need to align objects on stage..
How do I access Stage Class properties in Custom Class? Class: package { import Main; import flash.events.*; import flash.display.Sprite; import flash.display.Stage; public class Run extends Sprite { [Code] ....
Output: TypeError: Error #1009: Cannot access a property or method of a null object reference.
I 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.
The 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.
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?
I'm currently trying to add the resulting XML (xmlResult) to a textbox that is on the stage. I did try using MovieClip(root).[instancename].text = ..... however it didn't work - null object reference?
package { public class ChatHistory extends MovieClip { public function ChatHistory()
