ActionScript 3.0 :: Change The Value Of A Public Variable From Another Class?
Sep 7, 2010
I have a simple problem. I have two document classes. One is Main.as the other is Step2.as. I want to declare a public variable in Main.as then need to give it a value from Step2.as. That value will later be used in my next Document class Step3.as How would I write the code that gives the value in my Step2.as and then how would I write the code that retrieves the value in my Step3.as?
Note I can't import my Step2/ or Step3 document class into my Main.as.
Let's say I have a class, and I created a new object of this class in my document class. Inside this class, there is a public variable. How would I be able to detect a change in that public variable?
I've created 2 public variables in my Document Class...
public var _wall1:Wall=new Wall();public var _wall2:Wall=new Wall();I've then added them to the stage and given them relevant instance names...
stage.addChild(_wall1);_wall1.x=32; _wall1.y=510;_wall1.name = "wall1";I then want to use these variables in another Class (Ball.as). They need to be accessed in a function within the Ball Class constructor.
function bubble(event:Event):void{if(this.hitTestObject(_wall1)){ this.x += 1;}else if(this.hitTestObject(_wall2)) { this.x -= 1;}However, the following Error message keeps appearing...
1120: Access of undefined property _wall1.1120: Access of undefined property _wall2.Any pointers? Do I need to import something into the Ball Class to point to the _wall# public variables in the Document Class?
What would be the scoping to reach a variable within a external class public function FROM a function on the main timeline?In menu.as public function buttonClick()Need to reach a starFunction variable(var starFunction = such and such.@fn) within an if statement within buttonClick function.On main timeline(menu.as declared on first frame main timeline as var menuH:Menu = new Menu()In function aboutUs()here is where I need to use that variable for an if statement
How do I listen from the main class to a sub class for a variable change?
package { import flash.events.* public class DataBase extends MovieClip {
[Code].....
This is what I have so far for the sub class but I can't seem to figure out how to listen to this variable change from Main() or even if I am dispatching the event properly.
var environment:AvEnvironment = new AvEnvironment(...); addChild(environment); environment.addChild(new Terrain()); environment.addChild(new Player());
I am trying to access a public property from AvEniroments class through the Player class, however I'm getting an undefined property error (#119). I've tried the following:
this.x = AvEnvironment.xs // public property in this class this.x = parent.xs
I've also tried something like this:
var ev:AvEnvironment = AvEnvironment(parent); this.x = ev.xs
but I get a TypeError. Error #1009: Cannot access a property or method of a null object reference.
I've done a search on this and I can't find anything that makes sense
Its the first time I've created a document class and an object class that extends a movieclip. I've tried endless functions and properties to access the public function within the object class, but I'm getting lots of different errors. Both classes are within the same folder as the .fla file. I don't know what I'm doing wrong.[code]...
i've made a Tile-class where i set "buttonMode = false" for each instance. I have been able to test that the value can be change from the main AS.-file, so this part works.
Code: package { import flash.display.MovieClip;
[Code]....
This does change "buttonMode" but only on the very last instance. So this is where i'm at a loss -- i thought you could change all instances with one command like this but apparently not?
I have two document classes. One is Main.as the other is Step2.as. I want to declare a public variable in Main.as then need to give it a value from Step2.as. That value will later be used in my next Document class Step3.as How would I write the code that gives the value in my Step2.as and then how would I write the code that retrieves the value in my Step3.as?
Note I can't import my Step2/ or Step3 document class into my Main.as.
I declare a Boolean variable in my main class (Main.as file)[code]What I want is to change myboolean variable from inside a movie clip I've got on stage (when it reaches a certain frame).[code]
I've got two classes running...one is a document class (EgoGame.as) and another is a class linked to several similar movie clips (Ball.as).I'm trying to access a public variable from Ball.as which has been declared in the doucment class EgoGame.as.When I run the test the outputs states the following...1120: Access of undefined property _ballPlaced.Here's my code. What I'm trying to do is remove the event listeners from the Ball.as when the _ballPlaced variable is true, so that the user can't drag and drop the balls after they've been placed in a zone.
class Base { public var space:Number; } which gets extended by class Desc extends Base {
[Code]...
This doesn't compile. Say, you don't have control of the base class, what ways is there implement the same thing? The obvious is create a function setSpace(), but this object is being embedded in an already existing system that use the public space.
finally have a working hitTest (YAY!!!!), now, my code is setup to create 3 'sasquatches', the problem is for the hitTest to work, the variable "one" has to be public. Now, in the next bit of code we create 3 instances of one using a for loop, BUT they all three are in the same spot cause I can't figure out how to pass Random numbers to the variable each time it creates.
I think I've made some fundamental error here... I have a public variable a in class A, and I want to access it in class B, but I cant (access of possibly undefined property...) now every time I want to refer to a variable in class A I need to pass the variable reference to class B's constructor
i've got two classes and i'm not extending to MovieClip. I like to attach the mc in the constructor just because i'll be working with different MC's that have the same purpose.
however, im using private var loadedMC:Movieclip and now i've got another class that needs to be able to access the instance's variable.
for example, myClass.loadedMC , but this would mean having to make it public and I rather not go that route.
I'm trying to have a class that is an Object to hold details about the movieclip that it is attached to.
[Code]....
and two others of this nature. I didn't think you had to declare the 'key' of the object as a variable before setting it in the Object. So my guess is that it is angry about the class itself, somehow. (syntax or the like)
I have the below script as part of a small application I'm building. The script just creates cue-points along a movies timeline so we can add events etc to those cue-points.
[Code]....
It's creating the cue-points well, although I'd like to use the below variable outside of this function.
Code: var stampName When I try and use it I get an access of undefined property error, which I believe relates to the variables being private and within the function - but I can't seem to find a method to get this varibale public.
I have searched for this everywhere but it seems like every answer is either overcomplicated or simply does not work, and I know for sure there should be a more simple way of achieving what I need. So, until today, I have always coded from within the timeline. But now I realise why I should code in separate class files. However, I still want to include snippets of code in the timeline for simplicity's sake.
Is it possible to externally override a public function of a class (as opposed to override via inheritance)?
For example:
Code: Class Foo {public function doFoo():void {trace ("Foo"); } } Such that:
[Code]...
I know this is possible in JavaScript and ECMAScript, but the compiler won't let me get away with this kind of mischief in ActionScript, from what I've seen: It barfs up a 1168 Illegal Assignment error as soon as I attempt to assign a new function to doFoo.
I'm thinking specifically in terms of a "hot fix" solution where you deploy a small swf that replaces a specific chunk of code in a larger application, without the need to recompile/deploy the full application (or even see the sourcecode for that matter, just know the API).
I've made a Horizontal Bar Class which controls an element in library.So I have:Library: HorizontalBar MC - Using class HorizontalBarThis class has some public vars.Library: ContainerGame MC - Using class ContainerGameWhen I add this element to stage (HorizontalBar) inside ContainerGame MC I want to be able to trace public vars from its class inside ContainerGame.
