ActionScript 3.0 :: Can't AddChild To Null Object Type?
Feb 10, 2009
I'm trying to use addChild on a movie clip but can't as Flash gives me this error:Error #2007: Parameter child must be non-nullGreat. Okay.The movie clip into which I'm trying to add a child is set to null by default. How do I unnull it? Just what am I not understanding?
We are supposed to build a game, and each of us is to make a level. So we did, but integrating them is giving me issues. Specifically, each of our levels are contained within a symbol. I personally have a ton of symbols that point to eachother already (main.as, menu with various elements, level one, boss level) but for whatever reason whenever I try and addChild my partner's level it gives me "TypeError: Error #1009: Cannot access a property or method of a null object reference."
the way I've been doing it looks like:
var levelTwo:SkiHill = new SkiHill(); parent.addChild (levelTwo); parent.removeChild(this);
like I said, it's worked every time Ive used it between my own things. My partner's is a no-go. If I just slap his level on the stage and go it runs fine, and it will properly add/remove child to transition to one of my levels.
All I can think of is that I've checked all the names. I also noticed my partner didn't use an ADDED_TO_STAGE event listener, but adding that didn't help at all.
I'm having an issue with my flash code. I'm making a simple ball drop game and I keep getting this error
TypeError: Error #1009: Cannot access a property or method of a null object reference. at balldrop_fla::MainTimeline/gameLoop()[balldrop_fla.MainTimeline::frame1:46]
It seems to be talking about line 46 which is " ball.y += 5;"
I have been getting this Type Error 1009 at the following Loop: ActionScript Code: private function Loop(e:Event):void { for(var i:int=0; i<walls.length; i++) { if(hitTestObject(walls[i]) && hits > 0) { explodeX = this.x; explodeY = this.y; [Code] .....
ActionScript Code: parent.removeChild(this); But that doesn't work. Still get the error
I have downloaded Box2d ([URL]) and created a project that looks like this: [URL]. catalyst is the green cube and it has the base class "shapes.box", it is inside "world" which has the base class "wck.World". What i want to do is to add another "catalyst" from the library inside "world" when i click on add_btn. I tried to accomplish this by this code:
[Code]...
Symbol 'buttons', Layer 'Actions', Frame 1, Line 41061: Call to a possibly undefined method addChild through a reference with static type Class.
I'm using CS4 and AS3 I am getting no compile errors in my code, but in the output window, I keep receiving the following: TypeError: Error #1009: Cannot access a property or method of a null object reference. This prompt appears before I click on the button that is supposed to run the movie clip, so it appears that it is not the problem. I am working with buttons and movie clips; all of my objects are display objects or display containers, so I have no idea what the reference to a null object is. I have not created any custom classes for this, and don't think I would have to for such a simple project.
I was writing a preloader for an main SWF file, when I came across on the following issue: My preloader loads main site placed in another SWF - I decided for this way because I have some fonts embedded and it should have big file size. I've done preloader, that has no problems with loading for example images. I tried with SWF and there's a problem: mainsite.fla - there's only blue rectangle named "square" that is fluid. Here's the code:
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?
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 am attempting to make a class that handles the building in a game, but I can't get the object to come on stage. I can get everything to work if I am on the timeline, just not from this class. I've been getting this:
1118: Implicit coercion of a value with static type Object to a possibly unrelated type flash.geom:Rectangle.I got this error coming from the bold words when I tried to use this AS2 code in my AS3 stage. I'm currently trying to convent an AS2 printing of DataGrid to AS3. [code].....
I'm in the beginning stages of trying to understand AS3.Flash is outputting these two errors:1118: Implicit coercion of a value with static type Object to a possibly unrelated type Function.1120: Access of undefined property event_obj.
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.
why i keep getting Parameter child must be non-null. And my code won't display 5 enemyBlock objects onto the stage but only just one.
returns: TypeError: Error #2007: Parameter child must be non-null. at flash.display::DisplayObjectContainer/addChild() at flash.display::Stage/addChild()
I keep getting the following error msg below I would be very happy if some knows the solution to this: Error Msg: 1118: Implicit coercion of a value with static type Object to a possibly unrelated type flash.events:Event Object A dispatches Event as:
I am developing a drag and drop functionality and take a JPEG screen shot of droped objects. my problem is. when i drag and drop an object the object jumps off some distance.. i am unable to clear tat.. Below is my application.as file
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.
It's monday morning and somehow my brain won't comprehend why this error is happening...... could anyone take a look and shed some light on this please?

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);

[Code]....
I've looked up the error code, and it could mean alot of things.
I have an object which is assigned a number of properties:
var project_array:Array = []; var slideObject:Object = { project_title : myXML.projects.project[i].title.toUpperCase(),
[Code].....
but I'm not quite sure where to place this. If I place it outside of the object constructor, I get "term is undefined", I guess because it doesn't know what project_clips_array is - but if I declare project_clips_array in the constructor, it appears to need to be defined, i.e. I can't create a blank property. But I can't place it in the constructor either, because it doesn't seem to allow me to run a function within an object constructor. What is the proper syntax or arrangement of code for executing this function to get the array within the object?
The title might be a little misleading. Look at my code and I will explain
public static function loadTile(tileDir:String = "empty"):void { if(tileDir != "empty") { tPoint = new Point(0,0); tRect = new Rectangle(0,0,30,30);
[Code]...
I am trying to do tiling with sprites. I want my tiles to be interactive, so that is why I am using the sprite object instead of using regular bitMaps to represent my tiles. You might be wondering why I wouldnt just use graphics.beginBitmapFill(tImage); and graphics.drawRect(0, 0,tWidth ,tHeight ); to pick out the tiles I want to use. Well reason being is because it turns out that drawRect() first and second parameters actually alter the location of where the actual sprite sits at.
So if I set the x and y properties of the sprite to x = 20, and y = 20. then I set my drawRect(20,20). it actually adds an extra 20 pixels to my x and y coords of my sprite. And I know the reason why, I just need to know a better way.
