In my game, people can go back to the menu when they want. So when I go back to the menu, I make null all of the classes I instantiated. I then make them new again:
private var myClass:MYCLASS; // this happens once
someFunction () { // called when game begins and every time i go back to the menu and restart
[Code]....
Do I have to remove all of the listeners in the class I am making null?
Now when I go back to the menu, and do this, it is like the class is still instantiated and now there are two! When I shoot my gun, I hear it twice, and it traces out twice when I begin the game again. If I go back to menu for the second time, and restart game, when I shoot my gun it traces out three times from that same class that I made null.
I don't understand what is happening. It is like it is not truly getting rid of the class. Is it because I possibly still have something connected to that class? When I make it null though, I trace it and it reads "null".
In my document class named Engine, the stage variable is for some reason null:
package game { import flash.display.MovieClip;
[Code]....
This was working fine up until now. I just recently added two dynamic text fields into a symbol, and all of a sudden the stage is null. I really don't see the connection.
I'm currently stumped by this. I've created a class to load xml data from a txt file, then assign that xml to a variable named siteStructureXml. When I trace the value of siteStructureXml from within the class instance it shows the expected xml data. When I try to assign the value to a variable returnedXml defined on the timeline of my movie, it's value traces as null. I've a feeling it's something blindingly obvious..
I keep on getting "cannot access property of a null object" errors. With the debugger I pinpointed my issue at the line where I write stage.stageWidth.So somehow the stage is null. This is within my Document class which is linked with the .fla. The strange part is that I haven't had this problem until just recently.
Could you please explain how to disable this unnecassery, bogus, and semantically invalid behavior of the network communication classes when it receives a 0 valued byte? (specifically the Socket class.)
I did a separate levelData class to be able to flexibly add levels. I was happy with it until my supervisor ordered me to convert my levelData into XML. I did an XML version of the levelData's data (question, answers, correct answer...). I used the old class and converted it so that it fetches the XML.
All seems well, I did traces of my answers array and it printed nicely...
But the headache started when I tried this.
// This code appears in a different class with // currentLvl:LevelData initialized in the constructor. quizHolder.ansA.ansHud.text = currentLvl.choices[1];
I am trying to call a method that has some xml functionality and It keeps coming up null.What I am trying to do is; I have a page that has four dynamic text fields that get their content from an xml file. I would like to create a method that will output the contents to display in the dynamic field. Maybe my approach is WAY off here, but my supervisor wants all xml related tasks contained in a xml.as fileMain.as
I've basically got an MC (menu_mc) that is on the first frame of the main timeline. I want menu_mc to call functions on the main timeline depending on its status. When the function is successfully called, I want to move menu_mc, however I get a null object reference despite the object menu_mc being visible on the stage.
As you can see from the commented out lines, I've tried doing the same thing with eventDispatcher, but have been unable to listen to the event from the main timeline.It seems as if the function is being called before menu_mc is placed on the stage, despite the ADDED_TO_STAGE eventListener.
Ive been working on a project at the momment and ive been having an issue with accessing a MovieClip that has been created in another file called fileA and i want to access it from fileB the only Problem is that FileB Doesnt know it exists in FileA and it returns back this error
Code: Error #1009: Cannot access a property or method of a null object reference.
Code below is in fileA
Code: public var ChangeControlMc:MovieClip = new control();//This one is defined in FileA
My Code for FileB is as Follows
Code: public var ChangeControlM:AntarcticaGame // this is Defined in fileB trace("test level 1"); trace("called after super save()" + ChangeControlM);
TypeError: Error #1009: Cannot access a property or method of a null object reference. at QuizApp/createStatusBox() at QuizApp()
That's the error message I get when it tries to play. What I have is an swf that loads another when its done, the new swf is blank but has a document class to an AS file. It seems the problem lies when a function is not properly being added to the stage.
The function is added like this.. Code: package{ public class QuizApp extends Sprite{ public function QuizApp(){ createButtons(); private function createButtons() { if (this.stage == null) { trace("STAGE IS NULL!!!"); } var yPosition:Number; addEventListener(Event.ADDED_TO_STAGE, addedToStage); ...
I have a large creation in process that requires a lot of heavy animations and movement with vectors and really processor intensive. Just want to know, regardless of whether the project is huge or small, how to totally stop a class from working? I have three classes I am calling. "class1 = new Class1();" etc. When I am in the level, say, class2, I can still talk to objects in class1 even though I removed the class listeners within that class1 after I was done using it. It still is able to be called upon, and still running something in the background that I can't figure out what it is. I just want to know, rather than searching for whatever is causing the problem, can't I simply null the class that I never ever need to use again?
I tried that, but then I ran a trace and it still tells me that it is a class object. I reckon its because I have a "public var class1:Class1" etc, which means they will always have those objects associated with them, but still. I want to totally get rid of it for garbage collection, and because I don't want to use some of them at all, ever again. So basically, what is the best way to get rid of classes so that they aren't hogging up resources any more?
It does not matter where I declare the var __w:Who in the constructor, as a class var or in another function entirely. The whole thing still operates normally but it's irritating not being able to set my stage.align=StageAlign.TOP_LEFT; in the constructor.... I am guessing it is something in my Who class because it does not happen if I declare any other vars the constructor in Who pretty basic:
I'm trying to retrieve that mediator on another page like so:
var navPageMediator:NavPageMediator = facade.retrieveMediator(NavPageMediator.NAME) as NavPageMediator;
However, that statement returns null. If I try to cast it using the NavPageMediator(facade.retrieveMediator(NavPageMediator.NAME)) syntax instead, I get a TypeError: Error #1034: Type Coercion failed: cannot convert com.website.mvc.view.page::NavPageMediator@237560a1 to com.website.mvc.view.page.NavPageMediator.`
I can't, for the life of me, understand why NavPageMediator@237560a1 would be unable to convert to NavPageMediator, nor what happened in between registering the mediator and retrieving it that caused this. Especially since trace(new NavPageMediator() as NavPageMediator); returns [object NavPageMediator].
Incidentally, and this may be part of my problem, I don't understand what the @hash at the end of the object is (@237560a1). Is it simply an internal identifier for that class instance?
Edit:Left a bit of important info: The SWF in which I instantiate and register the mediator is separate from the SWF in which I try to retrieve it.
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 followed the example from a previous question and I am loading an external swf using a loader and inside the loader event handler I am trying to cast the loader.content as my custom class PanelReferenceClip which extends MovieClip
When I publish I receive a this error:
TypeError: Error #1009: Cannot access a property or method of a null object reference.
Just to make sure and test that the swf location was correct and the swf was actually being loaded, I changed the type of the content to as MovieClip and it worked fine.
EDIT: I also wanted to add that these swfs are being stored locally and not being pulled across the internet, multiple networks or servers.
I am not sure if I did something quirky in my class so I am providing the source to my custom class PanelReferenceClip

I have begun on a list: My reference is null!Stage is null! Convert this code from as 2 to as 3 for me! Crossdomain policies are in the way of my cool idea Dynamic property names I need to use stuff on the parent! I don't want my children to scale when I scale the parent! Classes vs instances. Mod note: I do not want this topic pinned, we will use a fresh topic once we have agreed to the content.
the script i wrote is working fine. but the script attached to the flash player which i have no control over is throwing a script error (im using IE8).how can i fix this? if i run it locally there is no error.
I have create a menu but when clicking on menu so that it shows, I get an error on the line because of the line "myMenu.show(null,null)". See function below:
private function createAndShowmyMenu():void { myMenu = Menu.createMenu(null, myMenuDataProvider, false); myMenu.labelField="@label"[code]........
sometimes I remove child and trace it afterwards and it outputs null although I havent yet set it to null, why is that? and do I need to set it to null also in that case?
I have the following piece of code(part of a much bigger program). I this code I am re-using a motion that has been previously used successfully. The trace stmts are used to identify the exact location of the error and the error conditions as best I can.[code]
When you cast null to an object using Object(null), the result is an object.When you cast undefined to an object using Object(undefined), the result is an object.But saying null as Object or undefined as Object remains null.Why is this? I can't find anything in the documentation about this.
The objects that result from these casts can have properties set on and read from them. It's as if the cast created information, or removed whatever special information the null and undefined values have. But there's no indication in the AS3 documentation that the null and undefined special types are actually objects.
I am trying to add an EventListener to a MC, but I am getting the 1009 error. My script is referencing a MC that does exist. I have verified that my code is typed correctly, and that my instance names are correct.I am creating a portfolio site. On the first frame I have my main navigation (well, it's actually not the first frame. I alpha-fade everything in so it's really the 6th or 7th, but I'm not sure how pertinent that is). The main navigation works fine (5 movie clips, fyi). Clicking them will move to a different frame, and the information and sub navigation for the frame will fade up. It is the sub navigation that I am having trouble with.[code]
As you can see, it doesn't even get to the function before it gets thrown off. I have verified that the instance names are correct. The script and the MC I am trying to add it too [I/]are[I/] in the same frame, which is what's stumping me. Normally you get 1009 when the object you're trying to reference is not there, but mine is!!Obviously there is something wrong with my EventListener. I am not sure what else do; there is a gap in my understanding of AS.
If I set an Object = null, does that remove all references to the Object's variables assuming there are no external references to said variables? Or do I have to manually set all said variables = null?
