when to use this in a classes?is there any specific rule?is it wrong to use this when you want to just access the stage that way?or is it better to pass the reference to the stage in the class constructor?
View 5 RepliesI'm trying to pass my object class as constructor argument. I have something like this:
package myclass {
import flash.display.MovieClip;
import flash.display.BitmapData;
import flash.display.Bitmap;
[code]....
Now, when I try to create my Example:
import myclass.Example;
var example:Example = new Example(myObjClass);
I get message, that I'm not passing any variable (Error #1063). Why is that? What is wrong with it?
I want to pass values to document class's constructor form html while embedding.
View 2 RepliesIs it possible to pass constructor arguments to instance objects which I place on the stage? Are the instantiations of instance objects centralized somewhere as with .NET WinForms so I can just edit the xxx = new CustomRecangle() constructor?
public class CustomRectangle extends MovieClip {
public function CustomRectangle(width:int, height:int) {
this.width = width;
this.height = height;
}
}
I have a bunch of movieclips( clip A and B for this example) in my library that I want to use the same base class (MyClass.as in my example). I assigned the same base class in each clips property window and then gave each clip a unique class name which doesn't exist so flash says it will create the class automatically.
Now if I create a bunch of A's and B's on the stage via actionscript, how would I send variables to the constructor in MyClass.as without having to creating A.as and B.as to pass the variables along to the base class? if I do: Var newA:MovieClip = new A (argument 1, argument2, etc) It says it expects 0 args since the A & B classes were created automatically by flash.
For example, I have the class Bullet, with a constructor: Bullet(start:Point, target:Point)constructor
But, if this Bullet class extends the MovieClip class, how do I pass start and target into it? Right now I am using attachMovie to create instances of the class. (They behave correctly with the static properties set by the constructor, but to be useful it needs arguments.)
I modified an Adobe Flash CS5 sample to create a swf with a preloader. In my FLA I've two stopped frames:In the first frame I only put this code (and a textfield showing percentage):[code]When I test the Adobe sample (it has no main class on frame 2, only a large image) anything works fine, but when I compile the modified version I get strange errors. In the Main class constructor I reference three movieclips, eg. this way: myClip.alpha=0, but it seems now Flash can't see them anymore (they are null). Why?

In a game me and a friend is creating, the levels are stored in MCs.In the level MCs there are several other MCs that the player should be able to interact with.
This means the objects in the levels need a stage reference.I can place all the objects manually and pass the stage ref in the constructor of the object's class, but this is a pain when the levels are going to be pretty big.
Is it possible to make sure that flash always passes a stage ref to the object even though it's not placed there by code?
my movie is linked to an external class called game, and in the game cosntructor I am trying to access instances on my stage. I have tried MovieClip(root).instancename, root.instancename and even tried adding an event listener to listen when the movie is done loading because I thought maybe it was because the instances on the stage weren't created before the constructor is ran. This is the main class, shouldn't it be easy?
View 2 RepliesI'm unsuccessfully attempting to instantiate a reference of a class that is passed as a parameter to another class. In this example there are 3 classes:
MainClass, Canvas, MyCircle
From the MainClass I am creating an instance of Canvas, which is passed a class reference of MyCircle as I want to create instances of MyCircle from within Canvas. However, the MyCircle constructor contains required parameters that are created from within Canvas. How can I pass and instantiate a class reference with required parameters?
MyCircle:
package {
//Imports
import flash.display.Shape;
//Class
public class MyCircle extends Shape {

There is a library component represented by Class A. But constructor of this class requires some parameters. When the component needs to be added dynamically, it's fine because of code :
var abc:A = new A(param1,param2)
But what if my movieclip is already present on the stage. I notice it gives out error, that the parameters are null.
Is their any way to insert constructor parameters for movieclips already on stage.
Is there a way I can reference a Movie clip I have on the main stage from a custom class of a document class?[code]
View 1 RepliesIs there a way to refer to a Movieclip on the stage from a class file of the document class
Lets say I have 3 MovieClips on the stage(a Circle, a Square and a Triangle)
I have the document class which calls another class that controls the MC on the stage
Example
ActionScript Code:
package {
public class Example extends Sprite {
//Create the instance of the class being called

I'm trying to get a small popup (a volume bar) to work from within a class.I made a piece of actionscript code that creates an empty movieClip and draws the bar into it and made it onto a class. The only thing I now have to do to add the bar to a programm, is create an instance of that class. Nothing needs to be added to the stage.The problem I encounter is that I need the bar to stay on top. New movieclips always get higher depths (using getNextHighestDepth()), so that's a problem.Calling swapDepths() for every new movieclip is far too complex and afaik there is no such thing as "bring to front" in actionscript, it only exists at design time, not at runtime.
So I though I'd use 2 layers/movieclips in the timeline, one for the volume bar and one for the rest, and add an empty movieclip to both.This way I know that all children I add to one movieclip will alway lay below anything I add to the second movieclip. (or is there an easier way to accomplish what I need? Levels maybe? I've never looked into levels, I only know they exist when loading a clip)This means I need to add a some extra stuff to the stage at design time, but if this fixes the issue.. ah well.But how can I access that movieclip from within a class? The reference "_root.volumeBarPlaceholder" works from within the main actionscript, but not from within a class because I get the compiler error "There is no property with the name '_root.volumeBarPlaceholder'";
How do I reference the stage from a class? I need to add eventlisteners to the stage for mouse movement. I also need to add custom cursors. I always get an error when I try to reference stage. anything. Or event if I do this:

I have a static utility class that must have a reference to the stage, and I'm not sure what is the best option for me to get the stage inside my class...
I've thought of these options:Pass in as a parameter of the function Have a static variable I can set to the stage I don't like either of these because they are ugly.
What methods can you suggest for me to get a reference to the stage in my static class?

View 2 RepliesI have created a custom class that extends the movie clip on frame 1 of the main timeline I create it var mainBox2:mainBox = new mainBox(); addChild(mainBox2); Now as I understand it you have to cast the parent as a MC so in the constructor of my external class I try this var myStage:MovieClip = MovieClip(this.parent); trace (myStage); I get null. What am I doing wrong?

I'm currently working on a AS3.0 project in Flash. I have a main movie clip in flash on the stage. This mc contains 3 frames. They represent the pages in my application. In each of those frames are a lot of nested MCs. Such as menu buttons, display content for the MC buttons, etc. Everything is controlled by a class extending from MovieClip. When I run the application and press the green button on the second frame in a nested MC of the main Movie Clip on the stage. The event must jump to the 3th frame in that main MovieClip.
Here's the problem
If I immediately press the green button, everything works great.
But this does not happen when I press a different menu button first.
Is there a way to get an instance reference to the document class to call a method of it from the stage's timeline?I see that here's a possible solution: using a singletonOther solution I though of is using stage.getChildAt( 0 ) but it's not very nice.Is there an 'official' instance reference? because the document class is obviously instantiated at startup, but is that instance accessible in any way without having to use a custom solution like the ones mentioned?
View 1 RepliesI'm trying to reference objects on the stage in the current frame from a document class in Actionscript 3 in Flash CS3. In this example, I'm trying to get at a dynamic text field with the instance name "question_txt", but there are also buttons and other things I'll need to get at to put event listeners on and such.
I have "Automatically Declare Stage Instances" checked in the publish settings, so the references should be there -- in fact, if I try to declare them in the class, I get errors about a conflict with the name -- but when I try to reference these objects (in any of several ways I've now tried!) I always get Null.

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 buils a flash movie using a document class, all works fine. When I load the movie using a preloader all reference to the stage as in stage.scaleMode = StageScaleMode.NO_SCALE; or stage.stageHeight throws a TypeError: Error #1009: I think i undrestand the problem, I am no longer accessing the stage properties. How do i access stage properties from the document class once loaded into the prelaoder?
