ActionScript 3.0 :: Using An External Class To Reference Functions From Another External Class?
Mar 25, 2010
I have a Main.fla which loads Main.as as its document class. In Main.as I have a public function named "Main" which runs a trace. I also have another .as file called Preloader.as, which also has a public function in it, this one named "Preloader" with simple trace in it. I just cannot figure out how to use Preloader() from the Preloader class in Main() from the Main class. Main.as loads up fine when the SWF loads and traces.
I made this class and I put it in the same package of Timeline.as (the Document Class):
package { import flash.utils.Timer; import flash.events.TimerEvent; public class Counter2 extends Timer { public function Counter2(delay:Number, repeatCount:int=0) {
I am able to use the Loader class to import an external swf into my project, its working great. But Im also trying to do a ImageSnapshot of the stage which works fine before the external swf is imported. After the swf is imported the ImageSnapshot no longer works. is there a event that the external swf is bringing with it that would disable it?
I'm unable to load forces.swf (assume I can't edit it, as I don't have the source code) through an external swf, due to Stage reference in the base class how would I go about loading it (and any other possible SWF) without errors being thrown?
Here is a link to the problem I am trying to fix:[URL]..

Say I have 3 fla files, each with it's own document class. I want to define some unique variables in each of those 3 files.Now once the variables (unique to each fla) are set, I want to call the same function - setting up the files. I want this function in a separate as file so i only have to make changes in one spot.How do I link the 1 .as file to each of the 3 doc class files and have it's function called in the constructor of each on
I want to create a MovieClip, pass this MovieClip to a function in another class where it will be modified.The problem is, when I pass the MovieClip as a parameter to a function and start making changes, the changes are only made locally. The "copy" of the MovieClip inside the function gets changed, but the "real" MovieClip back in my main game class remains unchanged. Here's the code from my Main class:
Code: var resourceLoader:ExternalResourceLoader = new ExternalResourceLoader(); var myMovieClip:MovieClip;[code].....
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'm trying to create a new instance of a MovieClip when the original one has been used. Would sound easy enough. Just use: var
instanceName:ClassName = new ClassName();
the class name/mc in the library im trying to duplicate is MCg1 so
var instanceName:MCg1 = new MCg1(); right?
However, the particular object in the library i'm trying to duplicate has a base class that is an external class file (just to control it's drag drop functionality)... i.e baseclass is not set to the standard flash.display.MovieClip, or whatever the case maybe. So i end out with a: TypeError: Error #1009: Cannot access a property or method of a null object reference.
I am trying to access a function in a loaded swf that has external class.. I would like to avoid having to put the function on my "Main" Doc class in the external swf and instead access the function directly from the class
This is what ive tried so far and it's a no dice:
private function startLoad(){ var loader:Loader = new Loader(); var req:URLRequest = new URLRequest("one.swf");
Lets say I have Main.swf and sub.swf, and I wanna load sub when I press a button from Main, but sub.swf has its own external class file attached, so here is the problem, when I load sub using loader class and I would get this message from the output panel:
TypeError: Error #1009: Cannot access a property or method of a null object reference. at subScript()
seems loader class can not access sub.swf's external class when sub is being loaded.
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 realize this is kind of an odd issue, but I am wondering if there's any way to get Flash to allow me to access a class's static functions using a class variable that points to the class. Example:I create a class called FooClass that has a static function named fooI then create a variable of type Class that points to it
Code: var class:Class = Class(getDefinitionByName("FooClass")); However, when I try to call foo() using the variable, it errors saying the function
Using Flash CS5 Professional I have created a symbol, dragged it onto the stage, and given it an instance name of GreenLight1. If I want to make this visible from the document class, I can simply do the GreenLight1.visible=true; and poof it's good to go when I test the file. As long as I stay in the document class I am good to go, but now I'm trying to move to another class and hitting ALL kinds of trouble just trying to get Flash to allow me to access this simple object. All I am looking to do is have this GreenLight1 go invisible (visible=false) when a certain condition occurs in this new class and Flash just won't let me access GreenLight1 at all. Things I've tried thus far:
stage is passed to the class and is referenced by _stage and is working just fine when I do _stage.addchild or anything like that. So I have tried "_stage.GreenLight1.visible=false;" and I get "ReferenceError: Error #1069: Property GreenLight1 not found on flash.display.Stage and there is no default value." My document class extends Sprite, so I figured I'd try the root function. So I tried "Sprite(root).GreenLight1.visible=false;" and I get "1119: Access of possibly undefined property GreenLight1 through a reference with static type flash.display:Sprite." I tried to create the Resource class as described therein. To which I came across the same problem that I started with in that it doesn't know what GreenLight1 is to begin with so I got "1120: Access of undefined property GreenLight1." Here is my code for Resource.as (am I supposed to pass something to this class from the document class?)
Main is my doccument class . how can i call Main.Caller
package { import flash.display.Sprite; import flash.events.Event; public class Main extends Sprite { public function Main():void { if (stage) init(); else
Given that both of these calls to getQualifiedClassName return the same thing (mx:Label), how would one go about programatically differentiating between an instance of a class and a reference to the class...
var lab1:Label=new Label(); var lab2:Class=Label; var qcn1:String=getQualifiedClassName(lab1); var qcn2:String=getQualifiedClassName(lab2);
In other words, how could I know that lab1 is of type Label, while lab2 is type "Class". typeof() simply returns "object" for both... getQualifiedClassName returns "mx.controls::Label" for both...
I am doing a looping background with 2 identical BG movieClip (B1 and B2). Those 2 are "new" by the same class.
var B1:MovieClip = new BG(); var B2:MovieClip = new BG();
But because this BG class picture is loader from the internet and the picture is rather big. When I addressed its loading by using progressEvent. The picture is really loaded 2 times. Is there anyway I create B2 based on B1 without using new BG() again? Since it definitely makes a new BG with Loader code inside.
I want to retrieve the var reference of an instance of a class from within the class. For example:
ActionScript Code: var ref:MyClass = new MyClass (); //then via some method, I would like to get the var ref inside the class ref.getRef(); //returns "ref" instead of [object Object]
[Code]....
You may ask why, well I want to do some spring cleaning inside this manager class I am making. Of course the above is a simplistic version of what I am trying to do.
I have created an SWFloader class that creates a container on the stage and loads an external swf into it. How can I click a hotspot in the external swf and make it instruct the loader class to load a new external swf? Basically, how can I access the SWFloader class from the timeline of the external swf?
I'm using the tweener class in this file just fine. But whenI try to use the sound manager class I cannot get it to load why?I keep getting type was not found ....
import com.richardsongraphics.soundmanager; var manager:SoundManager = new SoundManager(); =======================================
I am creating a Flash form which will include a drop-down selection menu from which a user may choose their state. I originally accomplished this by adding a ComboBox to the stage and then populated the ComboBox's DataProvider object with an XML listing of all the state names and the corresponding values. Everything works as expected.I have decided, however, that it would make the most sense to create an external class to accomplish the same thing. I have attempted to create such a class using the following code:
I found some code that let's you load variables from an external swf. I'm trying to adapt it so that I can use the symbols from external swf library in my main swf. I get an error telling me 'call to an undefined method...' and then the name of the symbol I am trying to import to the main swf (testMe123_MC). Here's the code of my external swf as:
