ActionScript 3.0 :: Getting A Null Reference Of A Visible MC When Calling Function From A Class?
Jan 11, 2010
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.
here is the menu.as code
Code:
package {
import flash.display.MovieClip;
import com.greensock.*;
import com.greensock.easing.*;
[code]...
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.

I'm having a hard time because of an "Error #1009:Cannot access a property or method of a null object reference" Iget everytime I try to run my Flash-movie. I've attached the codethat is contained in frame 1.The function bringUpEasyQuestion is defined on frame 2, alongwith other functions that are defined there. Now when I test themovie, I get this message:TypeError: Error #1009: Cannot access a property or method ofa null object reference.at MES_fla::MainTimeline/bringUpEasyQuestion()atMES_fla::MainTimeline/frame1()I've read that the Error1009-message means that you aretrying to access something that isn't there yet. And indeed, thebringUpEasyQuestion-function accesses objects that exist only onframe 2. But the first line of the function bringUpEasyQuestion isgotoAndStop(2);. The curious thing is that it works when i put thelast line of the code in frame one (the function callbringUpEasyQuestion(0);) on the first line
with the command gotoAndStop(2);?

I thought I understood this stuff by now; the objects within a function are onlyaccessible within that same function, unless you return it to whatever called the function.However I dont think that you can do that for a function called with an eventlistner, so I set up what I thought was a global variable and set its contents within the function, thinking that the contents would be accessible later:
ActionScript Code:
var bmpd:BitmapData;
var URLReq:URLRequest = new URLRequest("sample.jpg");

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 got a small problem with a null object reference. The problem is that the function "menuClicked()" not seem to work that good. It works fine if I'm not running it in the cases in the "urlChange()" function. But when I do so I get this error. The urls works fine btw. But I need to run that function to get the right content added regarding to the selected menuitem.

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
package com.components
{
import com.UI.DevicePanel;
import flash.display.MovieClip;

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?

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 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 custom function that doesn't function correctly the first time the function executes it removes a textFiled from the display list without a problem but the second time that it executes it won't remove a diffrent textfield and I don't know why here is the code from the time the textField is added to the diplay list to where its deleted.Btw the function in question is being executed by a custom event listener.....the errors i receive are TypeError: Error #1009: Cannot access a property or method of a null object reference...Also note that i can remove the textField in question from any function other thatn the one the custom event executes.
PHP Code:
sendBtn.addEventListener(MouseEvent.CLICK, sendMsg0,false,0,true);
msgOut.addEventListener(KeyboardEvent.KEY_DOWN, sendMsg1,false,0,true);
comboBox.addEventListener(Event.CHANGE,chFontSize,false,0,true);[code]..........

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 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.

I'm trying to call a function to another class after an event.
Here's my code:
From the doucment class:
public static function redrawMap():void {
removeChild(global.world);
var world:WorldHandler = new WorldHandler(40,30);
[Code]....
I can't get it to work correctly, I get weird messages like "Call to undefined method removeChild" and it pointing to the redrawMap function. Which means it found the function, but I can't seem to do anything with it.

I have two classes. One called Sledge and one called Sock, there is also the document class called Main. My issues are as follows: Inside of Sledge, I call a function that is defined inside of the Main document class. How would I go about telling the class to go to the document class and run that function? Would this also be the same for other classes or just for the document class? Inside Sledge, I have the following statement: if(hitTestObject(sock.myHitArea)) { /* somecode*/ }
sock is an instance of another seperate class, and by this point has already been created. However when I try and run this I am told it is not defined. How would i go about solving this?

I have done this type of thing a million times before, but I cannot for the life of me figure out why it isn't working this time. As of now I have three classes: Main, UI, and Bear.
Main creates an instance of UI and puts it on the stage. UI has, among other stuff, 7 instances of the Bear class sitting on the stage. The Bear class has a public function:
