ActionScript 3.0 :: Call A Method From A Instantiated Class?
Feb 25, 2012
I have this class called Main. And inside this Main class I have a method that I'd like to call from a the main timeline.
So on the main timeline I have instatiate the Main class like this:
var mainClass:Class = flash.utils.getDefinitionByName("Main") as Class;
var main:Sprite = new mainClass(this, mc1_mc, mc2_mc);
addChild(main);
Then on the frame after that, I try to access a function inside that Class like this:
main.prepareGame();
But I get this error:
Scene 1, Layer 'Layer 2', Frame 3, Line 61061: Call to a possibly undefined method prepareGame through a reference with static type flash.display:Sprite.
var pic:Picture = new Picture; // custom dynamic class with a method called onLoadPIc pic.onLoadPIc = onLoadMe; i'm trying to change the method of my custom class on the fly for this instance...
I have a class, my document class, called SilkRoadTweeter. as I also have a class called User.as In my User class I need to call a method called nonce() I have tried this, trace(SilkRoadTweeter(root).nonce()); But I get the error, TypeError: Error #1009: Cannot access a property or method of a null object reference.
They are located in the same package and are both importing each other. I am trying to call a function from Class2 within Class1, but I don't know the syntax. I tried: Class2.godoThisThingNow(); But it gave me an error 1061, call to an undefined method. What's the proper syntax for this, and is it even possible in AS3?
From my LoadXML class I am trying to call a method, named onBackgrLoad, which sits inside the Main class. I made the method onBackgrLoad public. Inside the LoadXML class in the method ParseData I added an event listener. This is supposed to call onBackgrLoad but it doesnt work
NetConnectionClient.as package com { import flash.events.EventDispatcher; import flash.events.Event; public class NetConnectionClient extends EventDispatcher {
From my Main class, in the method onBackgrLoad, I am trying to call a couple of public methods (i.e. xmlData, hintergrund & numOfProducts) located in LoadXML. I keep receiving an error message that "loadXML" is undefined. I dont understand why because I clearly defined it in the main class:
For some reason I cant figure this out,I have a function thats in a method in a class..I have a second method in the same class, trying to call the function from the second methodeg:
I have a RemoteObject returning a 'Schedule' class. I've created a client side RemoteClass to map to it. All properties of the class instance are coming in fine. I just not clear on how I go about calling methods on the class. How would I call a setter on startdate?
package classes.remote { [Bindable] [RemoteClass(alias="com.site.data.schedule.Schedule")] public class Schedule { public var id:int; public var modifydate:Date; public var startdate:Date; public var enddate:Date; }}
I have to know if a public method has been called from outside the class or from inside. The reason is that depending on this, one of the actions to be executed in this method vary a bit.
I have question regarding removing instantiated objects. Let's say i have a main class in which i instantiate a custom video player (or whatever) class:
Code: ... var videoPlayer = new VideoPlayer(...); addChild(videoPlayer); ...
And inside VideoPlayer class i have of course dozens of objects (movie clips, sprites representing different parts of VideoPlayer) and dozens of event listeners attached to them. My question is, if i want to remove this VideoPlayer class from my main class is it enough to just do:
I have a initApp.as which instantiates a class which needs to access the "currentState" property and the States array as well. However we cannot get this to work as we cannot see how we can access this information.
Within initApp.as currentState is accessed via "this.currentState". This does not work in the class which is instatiated within initApp.as. The following error is thrown:
I'm wondering if anyone has experience with if there is a big difference in performance in ActionScript 3 between keeping a class with only public static functions, and utilizing those functions often (as in a frame event at 30fps), and in turning the class into a "normal" class of which I instead make an instance and call the functions via the instance instead.
I just want to ask if is it possible to call a movieclip using the String Class together with it's instance name to use gotoAndPlay() method. I know how to use the instance name and the method but then what if I want to use a string together with the instance name and the gotoAndPlay.
I wrote a singleton class to keep track of some variables across my application.
I am getting a syntax error that I can't figure out, I am sure that I am missing something simple but it's been one of those days. Anyone see something wrong with my code?
The error is 1061: Call to a possibly undefined method setResult through a reference with static type Class.
My function in my singleton class
public function setResult(resultNumber:int, value:int): void { switch(resultNumber) {
Im getting this error: 1180C: as3_scrollbarAS3 ScrollbarsrcclassesMain.as, Line 1 1180: Call to a possibly undefined method addFrameScript. the actionscript in my .fla timeline is: _scrollBar = new FullScreenScrollBar(_content, 0x222222, 0xff4400, 0x05b59a, 0xffffff, 15, 15, 4, true); addChild(_scrollBar)
I am making my way with AS3 in little steps and have hit a road block. This is what I have:
I have a document class called "Document Class" I have a custom class called "Game"
I have instantiated an object of "Game" class and I am able to trace a class method which return a simple "HELLO". within my Game class, I have a variable(type Array) called "questions" as instance variable.
I would like to add questions to "questions" array by using "Mutator" method, or count the current elements with the questions array and return the total number of questions. I am unable to add or access elements to the questions array.
I get the above error. I did actually change a little code because I put it in it's own class.I call the below ShuffleArray class in my main doc class as follows:
I've been using Adobe Flash CS4 for a couple of days. I've drawn a worm, with eyes and a mouth and these pieces are all MovieClip symbols. I have exported them to actionscript with the class name being the same as what they are (ie. the mouth MovieClip is exported as mouth). The mouth has 2 frames, one smiling and one frowning. I need to mouth to stay smiling at first, so in Frame 1 actions I wrote:
I see where i was going wrong however when i change the instance name like you said i 1120: Access of undefined property snakePart. all of this code btw is at document class level and the movieclips are in the library not on stage
I'm new to oop and I'm trying to convert a auto scrolling TextField into a class. I guess it has something to do with there not being a stage when the class is instantiated but I'm not sure how to get around it. my code:
I got this Error : 1061: Call to a possibly undefined method addChild through a reference with static type Class.
what I'm trying to do :I have create a new class called Graph and make it extends Sprite and add a scroolpane to my stage and make an empty movie clip called content_mc and make the source of the scrollpane equals to content_mc
in the first frame i wrote this code
import Graph; var graph:Graph = new Graph();content_mc.addChild(graph);
I usually use if(object!=null) but it doesn't work well.
How can I verify if the class is instantiated. I want to get rid of the 'cannot access a property of a null object or reference'.
I mean, the 'var object:Object;' is just a reference to an Object class instance. When i initialize it with 'object = new Object()' it runs the code in the constructor, initializing it. How can I check if it has been initialized or not.
I've been struggling with this for almost a day now and I can't seem to find the problem. I'm making an instantiated FLV playback class in actionscript 2, but it just doesn't play the video
Here's the code, if I uncomment the camera parts and attach _cam instead of _stream it will show the camera feed, it just won't play my movie (and I get no errors whatsoever).
