ActionScript 3.0 :: Calling Function In Custom Class From Document Class?
Feb 24, 2009
I keep getting an "undefined property" error when I try to call an external function from within the Doc class. I added the error message to the Doc Class below so you can see where it occurs.
If I take the code from the Tooltip.as below and place it on the FLA's main timeline I can get things working fine, but I would like to move all script to classes. The document class structure looks like this:
Drag_and_Drop.as
Code:
package {
import Tooltip;// Import custom class
public class Drag_and_Drop extends MovieClip {
[Code]....
I realize that I could just combine all the code in the Doc class to get it working, but it would be nice to separate out this particular code which has only one use.
I'm trying to have a class reference a variable within the document class and have scoured the web but can't seem to find a solution. It seems relatively simple, but is a major stumbling block for me.
I want the variable in the doc class to increment each time a draggable object is within bounds and snapped to a box in the subclass. By tracking successful snaps, the objects will be placed one under the other each time.
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?
I was trying to load an external SWF (that contains the below code in its document class) with the Loader class but i keep on receiving Error #1009: Cannot access a property or method of a null object reference. So i tried to use the event listener Event.ADDED in MyDocumentClass constructor of the external SWF to let the document class be part of the display list before i invoke createRandomGraph. But when i place createRandomGraph( ) inside onStageReady, The compilation process hangs. When i leave the createRandomGraph( ) inside the constructor, it works perfectly as stand alone but will produce Error 1009 if loaded within the loader SWF
public function MyDocumentClass( ) { this.addEventListener(Event.ADDED, onStageReady);
I have a rather silly question but as3's document class always gets me confused.I have a public method on my document class. I want to call this method from another class that is instantiated from within an object in the library of the flash file (the same one on whose document class I want to call a method).
I have a public method on my document class. I want to call this method from another class that is instantiated from within an object in the library of the flash file (the same one on whose document class I want to call a method).
I have tried everything and nothing seems to work. How do I do this?
If I have a Document class that extends MovieClip, and I want to use it as the basis for another Document class, is it possible to create a subclass that extends the main document class and use that for a different FLA?
For example,
fla1.fla has a document class of MyMainClass: public class MyMainClass extends MovieClip fla2.fla has a document class of MySubClass: public class MySubClass extends MyMainClass
I've tried, but now I'm getting errors that all of my variables that reference stage instances aren't being found.
I'm trying to create a class which will create a tween for several different instances of an object. I am creating the instances in the Document Class. The trick is, I would like to specify how long each tween will take.
As you can see, I have a variable "myTime" which syncs the timer and the tween. This causes to tween to repeat and the clouds to continually scroll across the stage. How can I determine the var myTime at the time I create each instance of the Movie Clip mcCloud?
the website I'm work on has the document class Main. Within this website I have a movieclip on the stage which I built a custom class for its functionality and I linked this movieclip to this class to make it work. There is no reference to this movieclip or class in Main.
Now, I need to communicate between these two classes. Can I do this? Can I dispatch an event from the custom class linked to the movieclip and have the document class listen for an event? How?
package{ public class Character{ protected var _hp:uint = 50; //Character Health Points protected var _power:uint = 5; //Damage dealt
[Code].....
I`m instancing a Character and a Player in the Main Timeline, all in frame 1. When I use: ""player.attack(character)"" it works fine by itself.
So I added the if (defender._hp <= 0) this.win() which gives me the following error:
1061: Call to a possibly undefined method win through a reference with static type Character.
"defender" is a Character instance, "this" is a Player instance and "win()" is a Player method. I try to call the Player method inside a Character method using the Player instance adding the "." and his method name
Do I really need to define the win() function in the Character class? Is there a bypass to use a subclass method in a parent class method if it`s called from an instance of the subclass?
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'm not sure that I'm on the right track here. I've got what is essentially a 'gateway' movieclip and depending on the CLICK a corresponding movieclip (form) is loaded -- these all being in their own AS file. There are multiple corresponding pages that will all load/close in their own fashion but the 'gateway' will reload in it's own function-- consequently, I have this function on the main_AS. Can I trigger this function from the sub class or do I need to move the 'reload' function to a 'reload' class.
I've been searching around trying to work this out for a while now. There's been various ideas popping up, like dispatchEvent etc but nothing that seems to be a clear, simple way of doing this.What I'm trying to do is call a function from a class seperate (but in the same folder as) my document class.Specifically, I want to 'spawn' an object and run a function within that object's class from my Main.as.The snippet I have at the moment is as follows;
In Main.as: var object:class_Object = new class_Object(); object.spawn();
I have a two classes. One is linked to a menu and controls that. The other is linked to a 'viewer' movieclip. At the start (in the contructor function of the classes that relates to that mc) the 'viewer' mc feeds off an XML document, and an image is loaded into itself. When I click on a menu tab I want the image to change.
Both the viewer mc and the menu mc are on stage already. I tried to import the viewer classes into the menu class...
I;m converting some of my as2 classes to as3 and have run into a problem where my ships class cannot seem to call my vectorGraphics class. They are in the same folder (sprites).
The basic flow is this: On the main timeline I instantiate Ships and vGX.
I've been searching around the forums to find a solution of this problem. I have two classes: Monster and Player. Constructors are defined and the classes by themselves apparently works. My problem is that I want to get player.x inside the Monster class.
I have a variable, we'll call it helloNurse, defined in the document class, we'll call it Joy, as a public variable. Meanwhile, I have a movieclip within the FLA that uses that class as its document class that, simply put, needs to access that variable. I had read up that the following SHOULD work:
I am trying to rebuild an AS2 navigation in AS3. I built a button class (PortfolioNavItem.as) and a navigation bar class (PortfolioNav.as). This works if I use PortfolioNav as the Document class. However, I want to do things the proper way and call PortfolioNav from a Main document class (Main.as) but when I try it I keep getting that Error #1009.
Main.as package com.tagehaun { import flash.display.Sprite; //import com.tagehaun.PortfolioNav; public class Main extends Sprite { //public var portfolioNavItem:Sprite = new Sprite(); public var portfolioNav:PortfolioNav = new PortfolioNav(); [Code] .....
i am making a simple slideshow in AS2 (Flash CS3). I got all the core logic working fine in a FLA frame action - now trying to externalize it into a class. The first snag I hit was in trying to setTimeout -- when I passed a class method as the setTimeout function, it no longer could talk to the class variables/methods. I fixed this by passing along an instance of the class to the class method called by setTimeout something like this:
setTimeout(myMethod,delay,classInstance);
Now I've got a similar problem with my Tween.onMotionFinished() handler -- i want it to call another method in my class but it doesn't know what the class is or how to access it.How should this be accomplished? I've tried a similar trick in which I try to stash a class instance inside the tween (through bracket syntax eg. myTween["classInstance"] = this; but this doesn't seem to work.
Is this a case where I basicallyneed to create an event listener in my class & then just send an event out when the tween finishes? Or is there a simpler way to let the tween know about the class (without relying on instance names of the class itself)?I'm still new to OOP so not completely got my head around what can/can't access my class methods/variables especially when I'm creating objects like Tweens inside my class.
and then I just create a slideshow from an existing framesequence MC (who has stop() on frame 1) in the FLA thusly:
Code:
import com.pixelfarminteractive.slides.SlideShow; //SlideShow(slideMC:MovieClip,easeTimeSec:Number,holdTimeSec:Number,numSlides:Number) var ss = new SlideShow(slideshow_mc,2,2,4); ss.start();
I am trying to figure out how to call a title to come on screen when the titles are defined in an .as file that is not the document class. The titles would be defined in one .as file like the one I have posted below. I am trying to economize on the number of things that I define by not repeating code. So I wrote out the following quazy code to give you an idea of what I have done to create the titles. How I would call a title in the document class from this custom Titles class.
Code: package asFiles.stageElements { //import statements public class Titles extends Sprite { //variables defined public function Titles { [Code] .....
So I guess the question is what statement would I use to call one one of the titles above to be displayed?
I have a FLA (say Main.FLA) document class with a child MovieClip on the stage: into the child MovieClip I load other swf files: each of the files contains its own Document Class (every swf is a somewhat independent application, say quizzes and so on).For some reason I must use the Main document class to store data (scores or so) from the child swfs loaded into the Main swf. HOW do I reference the Main class? I can't find a way.[code]and dispatch an Event this way from the loaded swf document class to the Main class:[code]Now, first of all I don't know if this could even work. Secondly, I tried to make it work by adding an event listener to my Main class but id did not work.
Im trying to get my head round what is needed to catch event "Beep2", using dispatchEvent. The function "DoNext" is not firing, even though Im able to produce a trace result of the dispatchEvent "Beep2 true".
This code uses a CustomEvent Class to Extend the Event Class. Its right on my limit of knowledge so far,
I've made a custom sound class: ActionScript Code: package { import flash.events.Event; import flash.media.Sound; import flash.media.SoundChannel; import flash.media.SoundTransform; [Code] ..... What I would like that class do is to trace a variable that is on Main.as which is Document Class, after a sound completed playing.
