Actionscript 3 :: Flash CS5 Reference A Display Object From A Class Other Than The Document Class
Jul 28, 2011
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?)
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.
I am trying to code a flash app entirely in the document class. I am using GestureWorks with a touch screen. When a user essentially presses a button it calls a method that should hide a specific graphic but not the graphic they touched.
Essentially I need a way to refer to a graphic on the screen using a method besides 'e.target'.
I am receiving this error: Error #1009: Cannot access a property or method of a null object reference.
[Code]...
It can access photo1Sprite as 'e.target' when the button click happens on the photo1Sprite. The problem happens when to click one button (not photo1Sprite) and have it effect photo1Sprite. So I can make photo1Sprite react if my method is attached to it directly using 'e.target' but not if I am trying to call it from a method that was called from another element on the screen.
I found myself loading a new XML file every day and so decided to create a small class that will load the xml file and return it.The class is loading the file but when i try to return it to a new xml object in the document class it doesnt load it.I think that it's something to with the return being in a nested function but i tried a few ways and non seems to work.
[DOCUMENT CLASS] loadXML:LoadXML = new LoadXML(); myXML:XML = new XML(loadXML.loadXMLFile("gallery.xml"));[code].....
How do I reference MovieClips or Sprites created in the Document class from a custom class?[code]But I have a lot objects I want to reference so using the above method would take to long.I know I can do this to reference a MovieClip on the main stage from a custom class.[code]Would referencing the sprite created in the document class be similar?
I'm trying to reference the document class from inside a MovieClip that's dynamically added to the stage. I'm using this script: Code: documentClass(root).someVar; Where "documentClass" is the name of my class (duh).
This works fine, however -- when I move the class file into a folder (and make all the necessary revisions to point to the file) this doesn't work (everything else still does). I get a "not found, possibly undefined method" error. The class name is technically com.documentClass now, how do I point to that? The file is an Adobe Air file.
What I'm looking for is a way to reference the document class instance, to be able to access functions and variables that other classes need. I'm currently doing it with this little piece of code I found on some blog or forum.
Code: Select all// This is in the document class private static var _instance:DocClass; // I have tried setting this to public and accessing it directly as well public static function get instance():DocClass { return _instance; }
[code]....
This seems to work as it should in Flash CS4, but when I try to run the same code in CS5 I get the following error message:
Code: Select allC:UsersImpenDocumentsMy DropboxFlash Project\_SPELTankGameMenuShop.as, Line 238 1195: Attempted access of inaccessible method globalFunction through a reference with static type DocClass.
So I have a MovieClip symbol created in the Flash IDE with a baseClass of flash.display.MovieClip and Class name of "Square". I have placed it on the timeline of my fla at frame 30 and given it an instance name of "square". How can I control that MovieClip from my DocumentClass? I have an ENTER_FRAME listener listening for the arrival of frame 30. At that time I want to simply do something to the "square" MovieClip. But I keep getting a compile-time error of "1119: Access of possibly undefined property square through a reference with static type flash.displayisplayObject.".
Is there a way to get an instance reference to the document class to call a method of it from the stage's timeline?I see that here's a possible solution: using a singletonOther solution I though of is using stage.getChildAt( 0 ) but it's not very nice.Is there an 'official' instance reference? because the document class is obviously instantiated at startup, but is that instance accessible in any way without having to use a custom solution like the ones mentioned?
I'm trying to reference objects on the stage in the current frame from a document class in Actionscript 3 in Flash CS3. In this example, I'm trying to get at a dynamic text field with the instance name "question_txt", but there are also buttons and other things I'll need to get at to put event listeners on and such.
I have "Automatically Declare Stage Instances" checked in the publish settings, so the references should be there -- in fact, if I try to declare them in the class, I get errors about a conflict with the name -- but when I try to reference these objects (in any of several ways I've now tried!) I always get Null.
I'm using Flash Professional cs5/AS3 I'll try and describe this the best I can. I'm new to ActionScript. So, in my timeline I have a var on a frame that represents "lives" and i have some code in the timeline that takes down the number of lives depending on certain events, which all works great.
so, now i wanted to make a constructor class that I could reuse for a bunch of movie clip objects and I only want these objects to be able to move if the lives variable is greater than certain number. So now, building my constructor class for these objects i just wanted put an if statement that is looking to see if the lives are greater than a certain number, which if it is then should make these objects do what i want...But, when i run the project I get "1120: Access of undefined property lives."
lives is the var I made obviously like I said, and it works fine being referenced everyone else except when I make a new .as file for these objects then try and reference it. I get the same error when I try and establish "lives" in the main project class too. I'm not sure where I should put this var or how I can make it so i can reference it from an object class. I'm not really sure how to word or describe my issue which has made it hard to search for a tutorial.
How can i cast a object to another type? in AS3 i tried putting (objectType) infront of the variable but it doesnt work, below i have added objects of fishes into the child, and i am getting the fishes back out when mouse down is triggered, and then calling the fishes what to do. however i cant call the method of the custom class fish because it is a displayobject.[code]...
I have buils a flash movie using a document class, all works fine. When I load the movie using a preloader all reference to the stage as in stage.scaleMode = StageScaleMode.NO_SCALE; or stage.stageHeight throws a TypeError: Error #1009: I think i undrestand the problem, I am no longer accessing the stage properties. How do i access stage properties from the document class once loaded into the prelaoder?
I am using the Loader class to load 3 external swfs: sharedTopics.swf (does not have a document class) fonts.swf (document class is FontManager) main.swf (document class is Main) The same loader is used to load all 3 assets.
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 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?
So I had a working .fla, with a document class package in the same directory. Everything was fine, until moving both to a new directory, now the fla cannot find the document class. WTF?
I have created an enemy object from document class. if my enemy score becomes zero, the enemy must get removed.Is there any way to remove that object by destroy the object from document class?.
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 have two files, MenuButton and JerkChicken (my document class...don't ask).
MenuButton loads a font and then creates a textfield with a background rectangle that is inivisible (for a hit state).
In my document class (JerkChicken.as) I build a menu with the following function:
Code: private function buildMenu() { var labels:Array = new Array( "one",
[Code]....
Or something similar...basically I want to take the width of the menu button, add a bit of space and then place down the next menu button (to make a horizontal menu bar).
The problem I am having is menuButton.width is returning 0.
In the menuButton class when I try to trace the width (i.e. trace (_bgWidth)) I am getting the width but when the button is created in the document class, I am not retrieving the width.
I guess what I am looking for is to somehow send "_bgWidth" from the MenuButton class to the document class...but I don't know how to do this.
I'm trying to build a shuffle function that somebody gave me into my card game. I two external .as classes; one is Shuffle.as, which is my document class, and the other is card.as. I'm building the shuffling function into Shuffle.as. I think I'm getting close to making it work, but there are some problems. I keep getting this error message: "5000: The class 'Shuffle' must subclass 'flash.display.MovieClip' since it is linked to a library symbol of that type." Here is my code. Shuffle.as code
I'm using the following code to arrange indexes of objects on the stage the only problem is I can't access an Object that has been made in a class in an external AS document. if i go into the document and trace I can see it but i can't access it from the document class and arrange its index anybody have any ideas?
