ActionScript 3.0 :: Call Parent Class Function From Child Class?
Nov 25, 2010
Lets say I have a Main Document Class called Main. I also have a child class called childClass that call a function from the Main class and is also imported in the Main class. How should I call the function? I tried this , but when calling the function, it's getting me error.
I'm trying to call a function in one child class (Circle.as) from another child class (Wedge.as). Circle.as is instantiated by the document class (Tree.as), and Wedge.as is instantiated by Circle.as. How do I do this? This is my code:
Tree.as package com.treediagram { public class Tree extends MovieClip {
[code]....
How to call a function in a Class from another Class?but it was a bit hard to follow as it relates to my problem. One of the solutions worked, but was commented as being bad form, and another did not work, so I want to make sure I structure my code properly.
How can I make a call to a function in the parent class of the class I'm in.
example:
main class
Code:
package { import flash.display.Sprite; public class mainClass extends Sprite {
[Code].....
I realise that there is some stuff that is missing in the "full" code here, but that's just because I'm to lazy to write it all...
How do I get the "someButton" in the "child_class" to call the "theImportantFunction" in the main class? I know that it is possible to make a "dispatchEvent" in the "mouseClick" function, and then add a eventlistener in the main class.. But is there another way to just call the function directly?
I have two child classes ClassA and ClassB both inherit the same base class.
I also have a function that has a parameter which could be an instance of either child classes.
function Test(instance):void //instance is either a ClassA or ClassB instance { instance.DoSomething(); }
However, when I run the test, it's always the BaseClass.DoSomething() get called. How can I use the same function (DoSomething()), but call child class function instead of the base class one?
I think this is a pretty simply problem but I do not seem to be able to pull it off. Basically I have a parent class A, and a child class B.Class A instantiates class B with addChild.There is a shared object which is being updated from a java server (red5) that has an event listener attached to it in class A.I have a function in class A which will pass certain, specific updates from this shared object to class B.The problem occurs is that when class B is instantiated, the event listener from class A doesn't work anymore. I have not removed the event listener from A.?
I have a function (let's call it testFunction for right now ) on the actions layer in the main timeline There is a movie clip with 15 frames long in the library
i want to add a child of the movie clip on the stage, and call testFunction when it finishes playing
how can i do? i tried to call it in the child but nothing works
Or, is there any way to show child on the stage for only a period of time like 1 second and then remove it automaticly?
Is it possible to call a child function from within the parent? I know to go child > parent, you can do parentApplication.functionName(parameters);, but what about going the other way... that is parent > child?
I have a main MovieClip that creates a new instance of an imported class which is a page in the application. This class tries to call a function on the main MovieClip and it's not finding it. I've done this in the past without any problems with separate swf files and loaders, and with movieclips in a library. I'm at a loss on how to resolve this. Here's what I'm doing (simplified for posting):
How can I run function of the main document class from a class of a MovieClip? I usually just used MovieClip(parent).function(), but now my MovieClip has another parent. Or what do I have to pass to the MovieClip class when creating the MovieClip to acess the main document class?
I have a Document class that instantiates a class named Other. I need to call a function in the Other class from the Document class.I'm getting this error: Call to a possibly undefined method OtherFunction through a reference with static type Other.I have read online that you need to use make the functions static or use a getter function but I'm unclear how to do that. I haven't been able to make it work and I feel like i'm missing something fundemental with this problem.below are simplified versions of the classes.
I have a document class called Main.as In the class constructor I have the following listener:
enter code here var listeningFORModeChangeToStudent:Sprite = new Sprite; listeningFORModeChangeToStudent.addEventListener(TellAllModeChangeToStudent.STUDENT,exp); addChild(listeningFORModeChangeToStudent);
[code]....
In a third class I make a call to the despatcher in the previous class:
enter code here var ThisTellAllModeChangeToStudent:TellAllModeChangeToStudent = new TellAllModeChangeToStudent; ThisTellAllModeChangeToStudent.tellAllModeChangeToStudent();
I have trace statements in eveything and from this I know the despatcher in TellAllModeChangeToStudent is being called.The problem is that the listener in the main.as is not calling the function exp.I cant see why and I dont know how to check if the listener is actually seeing the dispatch event?
also... my other classes that are run through initCore aren't doing anything but tracing, so I know there loaded but none of the objects that are supposed to be created are being created.
I've been using greensock classes in a parent movie, but am now looking to use the same classes from within some child movies, but it doesn't work (I presently have to import them into each child movie - what a waste).
Do I need to create the classes as a shared library object perhaps? If so, how would I go about it? as I've only ever done this for MCs or MP3s.
I have a SWF with a document class called ClassA. I'm loading in an external SWF with a document class of ClassB. Then ClassB is loading in an external SWF that is used for graphical assets.
The problem is that all of the assets in the third SWF all extend a class called Actor. The assets swf is loaded and set as the var "_assets".[code]...
I wrote two projects using the same 3D library but I modified it pretty heavily in one (to the extent that the inheritance is pretty different on one) - now I need to load one into the other and I'm getting some weird errors that look like the child swf is trying to use the same class definitions as the parent even though it should be in an entirely different namespace.
So - anyone have a tricky way of forcing the loaded swf to use the classes it's compiled with rather than the ones already defined in the parent swf (and vice versa) or do I need to refactor all my stuff?
If an object, or say... a document class, creates an instance of a class (and stores it as a variable), and it doesn't pass any arguments to the constructor of the class, can that class object, by simply having a function of it called by the parent, tell who sent it that command/request?In other words, can a class object know who called it (such as it's parent) via a (seemingly) anonymous call?
I have a class linked with a movie clip, and in this movie clip I want to be able to add an event listener that calls a function in the Document class (the class you link with the fla as a whole). How can I do that? Say the name of my document class is KPScript.as. In my GameController.as class, I want to listen for key input and call pageChange() in KPScript.as when it gets called. Would I have to import KPScript.as into the GameController.as? If so, I wouldn't want to create another instance of the KPScript object.
I'm using a PreLoader as a parent SWF that loads the actual website as a child SWF. In the website SWF, the child SWF, will MovieClip(root) still work and refer to it's own root, or the PreLoader's root? And would I still access the websitite's document class (the child's document class), through MovieClip(root)? What if both files have a document class?So my main question is how do document classes and MovieClip(root) behave in the scenario when you have:
i've got an inheritance chain of AS2 classes set up where i have an array in the 'child' class that i'd like to be able to access from the 'parent' class:
bottomClass.as -'parent' topClass.as -'child'
my question/dilemma is: how can the parent access the properties of a child class...is this even possible, or am i just looking at it wrong?

That class has a loop that creates / instantiates a number of copies of another movieclip from the library. This second movieclip has a textfield child in it. When I convert this textfield to a movieclip I can access the properties of it fine, but just as a dynamic textbox I can't access it.
This is the custom class of the second movieclip that gets instatiated a few times by the first custom class...
This custom class relates to a movieclip that has a child MC called recent_text (which I can access ok) and in that child is another child (a dynamic text field called "aDynamicTextBox", which I can't access)[code]...
I have a child class that is loaded into the parent class when the swf begins, like so: var myvar = 'hello'; public function Parent() { this.child = new Child(); }; How can I retrieve the variable 'myvar' from within child?
If an object, or say... a document class, creates an instance of a class (and stores it as a variable), and it doesn't pass any arguments to the constructor of the class, can that class object, by simply having a function of it called by the parent, tell who sent it that command/request? In other words, can a class object know who called it (such as it's parent) via a (seemingly) anonymous call?
