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'm making an image revealer in flash, but I can't wrap my head around how to constrain the slider bar to the area_mc. Mainly in the mouseMoveHandler. Can someone please give me some pointers?[code]...
View 1 RepliesI'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 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.

i am working on a project that has separate swf files serving as different sections (students, faculty, etc). for each section, on the first frame i have a combobox that lists the different values within that particular section. when a user clicks on the value, it takes them to the specific frame within that swf. there are two problems:
1. when the user selects a value, everything functions correctly but an error is thrown that says:

I have some simple Sprites that I'm putting into an array. However, when I click on them I want to trace what their position is in the array. How do I go about doing that?
ActionScript Code:
var myArray:Array = new Array();
var mySpriteOne:sprite = new Sprite();
mySpriteOne.graphics.beginFill(0x000000);
[Code]....
I want to add some mouse click listeners and then I want to trace the currentTarget's position in the array. I just have no idea what parameters to give the trace().
I basically want to trace an object within a layer (or the child within a layer), for example:
test.text = _level0.child;
And this would give me the movie clip name contained within the layer?
check out the attached file. Don't ask me why, but I need that yellow rectangle to follow that grey dot, which rotates around randomly... but see, if you place the dot to the center left of the grey rectangle, you see that the yellow rectangle screws up. I've deducted that this happens for this reason: to the left of the grey rectangle, the rotation value is 178... 179... 180... then it jumps to -180... -179... -178... (you can try this out using an onEnterFrame function and tracing the rotation of an object that follows the mouse).
Since the yellow rectangle follows the grey dot with an ease, it doesn't just do: rectangle._rotation = dot._rotation But instead: rectangle._rotation += Math.round((dot._rotation-this._rotation)/rotatespeed) Some of you guys should already be familiar with this kind of movement, but it's usually used to move objects smoothly. The bug here is that whenever that dot randomly jumps up into -180 from it's original position at below 180, it screws up the yellow rectangle.
I'm just starting to learn about classes in actionscript, I am following along with Moocks book Actionscript for Flash MX and are trying to execute a trace on the properties of my ballclass but all I get is undefined. He is what I have in my actions panel.[code]
View 5 RepliesI have an array of objects. What I would like to do is get the last index of an object whose property equals a certain value.
Ex:
// this occurs on a mouse click
var stockObj:Object = new Object();
stockObj.ID = "an_id";
stockObj.category = "a_category";
array.push(stockObj);
//psuedo
trace(array.lastIndexOf(stockObj.category=="a_category"));
I would like this to trace the index of the object whose category property equals "a_category"
The author shows a function that is supposed to trace the contents of any display object. In his example file he has several nested movie clips on the stage and everything works just as it should, this is the code.
ActionScript Code:
function showChildren(dispObj:DisplayObject):void {
for (var i:uint = 0; i < dispObj.numChildren; i++) {
var obj:DisplayObject = dispObj.getChildAt(i)
[code]....
The problem I am having is that when I open a new actionScript 3 .fla and try to recreate the nested movie clips and use the same code I get these errors:
ActionScript Code:
line 3 1061: Call to a possibly undefined method getChildAt through a reference with static type flash.display:DisplayObject.
var obj:DisplayObject = dispObj.getChildAt(i)
line 2 1119: Access of possibly undefined property numChildren through a reference with static type flash.display:DisplayObject.

I'm a complete Flex/Flash noob, running Adobe Flash Builder 4 Beta 2. I have a main component that needs to be able to call several popups, each mostly the same except for one function and a few labels. Obviously, I'd prefer to be able to define this function and change those labels when calling the popup instead of having tons of .mxml files with nearly the same code, I just don't know how to do it. I figured out how I can change the labels, but not sure how to redefine the function.For simplicity's sake, let's say my code looks like this:
main.mxml:
<?xml version="1.0" encoding="utf-8"?>
<mx:Module xmlns:fx="http://ns.adobe.com/mxml/2009" :s="library://ns.adobe.com/flex/spark"

Basically, the problem I have is that I'd like to limit the predators to their own hunting environment, ie. Polar bear to ice, killer whale to sea so that the penguin has at least some chance of avoiding either predator. My initial idea was to define a boundary (apologies if this isn't the correct terminology) around the ice, thereby achieving what I'd like but I have no idea how to do this. Am I thinking about this too simplistically? Also, I would like the killer whale to retain its ability to swim under the icebergs. Note: As you can probably tell, the killer whale is on the lowest layer below the sea and then the ice is on a layer above the sea.

I'm trying to make children of a tile and put them in their respective locations. To do that, I need to know what kind of tile is to be created, but if I just use my old method:[code]I will have to use a chunk of code like this for every single imaginable tile. Obviously, that is not efficient! So I'm trying to optimize it by having what tile type is to be posted saved in a string, then using the string to refer to what child is to be created, something like below:[code]how to make the above code work. Surely, there is a way to do this?

I intended to write a script that would create a dynamic guided character motion. The drawing API tut gave me an idea how to do it. I thought I'll write a script that would draw a line (or a curve) and would put it into guided motion layer. So I just wrote it by the tutorial and put it into guided motion layer. Yeah, that was naive.So how do you define where (layer) the script would draw curve/line? How do you define the layer in which the new object would be crated?
