ActionScript 3.0 :: Referencing Instances In Loaded Movie?

The following code gives me an error:1119: Access of possibly undefined property sp1 through a reference with static type flash.display:Sprite.Not sure how to get around this issue... these things used to work in as2, I guess not anymore in as3...

It's me again and I'm running into a problem. So, I have this movie clip that is nested inside multiple movie clips. I want to tell Flash to perform an action when that movie clip hits another movie clip in the main timeline. It's just collision detection for a game using the hitTestObject code. I was thinking of using MovieClip(root), but that won't work since it's nested so much.

I'm having trouble referencing variables in a loaded movie. I read in other posts that you simply refer to the variable as if it belongs to the clip you load it into, however this doesn't seem to be working for me

I have a placeholderMC and then two instances of that placeholderMC (both with different instance names) in a containerMC. This containerMC is then animated using tweens, not actionscript.
I need to be able to load a JPG, PNG or SWF file using AS2 into the placeholder from a server. At present, loading the movie requires a specific target path which will only load the movie into the one instance. Is there some way I can load the movie into the placeholder without being as explicit in the path, such that it will be loaded into BOTH instances of the placeholderMC in the containerMC?
In laymans terms... I am loading a graphic and using the second instance as a drop shadow reflection under the first. The reflection has a different instance name so that I can cacheAsBitmap and use a gradient on it as a mask at runtime, it is also flipped vertically, so that like a reflection it is upside down.
The other problem I am experiencing is that when the containerMC is removed from the stage during the animation, the movie is unloaded as well and needs to be reloaded if i require the containerMC again. Is there anyway around this or is that native behaviour to flash. Ideally I would like to only have to load the Placeholder images once at the start of the file and then have them available for use as and when they are needed throughout the movie... does this require them to be on the stage the entire time?

referencing instances of an object in AS3
I want to be able to build a navigation and reference each navigation item separately changing each instances properties depending on rollover actions etc.
I would have thought that once the name is assigned through the for loop that would stick, eg. the following code would create 3 vars called navItem, each with the name 0, 1, 2. But it seems if I trace the name outside of the for loop each is called 2. I think Im misunderstanding something really simple!
public function buildNav():void {
for (var i=0; i <itemNum; i++){
var navItem:NavItem = new NavItem ();

I'm using duplicateMovieClip to create instances of a clip. Then I use an array to name the clips. In the scrip that duplicates and names them, I also have an onRelease function to make the mcs do something when you click them. I can't get this onRelease part to work.
I need to:
- swap the depths
- load some text
- attach a movie from the library
I can't see any errors with my script, so I hope someone can look at it and give me a clue. The part I'm having trouble with is:

I'm creating a game in flash for a university project, and learning actionscript and programming as I go. I'm very much still at a beginner level - at the moment al I have is some actionscript for drawing rectangles and moving them about the screen. This is what I'm having trouble with at the moment: I have a class called 'Creature', and I want instances of it to interact with each other. I want them to do something when they come within a certain distance of another instance. And I want them to be able to pick a random other instance to get the location of, in order to do something with that information.
What I think I need is: A function for telling the distance between two (x,y) points.
A way of referencing the nearest other instance of the class. And a way of randomly selecting from all of the instances of the class.

I have a swf that is loaded into my main swf with the loader class. When I click a button in the main swf I want to call a function in the loaded swf Main class.
When I do a trace it is showing the loaded clip as [object Home] which is the name of the Main document class associated to the loaded swf. I have a public function in my Home.as called startAnimation() but when I try to call it I get

I'm loading an swf say "test.swf" which gets loaded in imageLoader , so I can get its content by :
imageLoader.content
So if I wanted one of the movieClips inside it I would do this :
imageLoader.content.testMovie.transform.colorTransform = someTransformation;
But when I do this, since the movie is not loaded the file is not compiled and gives me an error your referring to something that is not there. How else am I supposed to reference a content that will be loaded later?

The starting point is that I load an external PNG file into an open SWF application with the following code:
---------------------------------------
var loadListener:Object = new Object();
loadListener.onLoadInit = function():Void {
//do certain actions - not relevant for my question
};
[code]....
That works fine. The problem is how can I later reference to 'flower02.png' as BitmapData which is loaded as a movieClip into the movieClip 'mc1' to execute certain BitmapData methods like in particular 'copyPixels()'?I'm aware that I could use:
---------------------------------------
import flash.display.BitmapData;
var libId:String = "flower";
var flowerBmp:BitmapData = BitmapData.loadBitmap(libId);
---------------------------------------
In this way I could reference my BitmapData by its variable identifier 'flowerBmp'. But this would require that my 'flower02.png' is already in the library which is not possible for my purpose.

I have a widget containing a number of displayobjects, i.e. up arrows, down arrows, tab 'buttons', backgroundrectangularblocks, sliders, company logos etc.I am currently creating these displayobjects using the graphics class with parameters taken from an external file, things such as fontsize, font, colour, width, height e.t.c and adding them as children of "container" sprite objects for easy manipulation and referencing later can these assets be loaded in their entirety externally, rather than being created using graphics class draw methods (which I want to avoid) as some of the things I need to design cannot be created in pure actionscript very easily (if at all?), and then used or do they always have to be in the library and instantiated from there?
if the first question is yes they can be loaded externally, this question probably isn't needed; however, if I have to put the items in the library and recompile each time a client wants to use say a curved blue up arrow instead of a yellow one and then decides he wants a yellow circle instead then how do I write the code to do the following:-Say on my first ever compile I have 'upArrowBtnset1' in the library, I instantiate it and use the instance name to access it in the usual way using standard code,
upArrowBtnset1.addEventListener.... container.upArrowBtnset1.scaleY = .3 e.t.c
Now if they send me a second set of 'upArrow' graphics they want to use I could either update all the upArrowBtnset1 assets with the new graphics meaning the original set is no longer available to the client and I would either have to hold a "original set" FLA file with the first set of arrowbuttons or I could import these to the library as upArrowBtnset2 and a third set they send as upArrowBtnset3 and so on each time I am sent some new assets; I would then recompile them into the SWF and adjust the references to the new assets within the code. In the code, for each instance of "upArrowBtnset1" I would have to rename them to "upArrowBtnset2", recompile and send it back to the client.
Because I have already abstracted the font/colour/size choices out to an external file, they can change that as much as they like without a recompile which is what we want. The problem comes if they want to use set1 again and haven't kept the original "set 1" compiled SWF. It would be easier to abstract the 'setchoice' also to the external file. The SWF would over time build more and more available sets that they could use by just changing an external variable.
For example, if the designer wants to use set 1 on Monday, set 2 on Tuesday and set 3 on Wednesday I want to make it so they can just adjust an option in an external file to "setchoice = 3" for weds instead of either having to recompile the swf each time or they have to have 3 versions of the SWF for each asset set. The idea is that as more and more assets are added in, they have more and more choices. Ideally, in an external file there would be a list of assets and links to where they are loaded from. (i.e question 1 above).
If I have an external file (say XML) which holds the setchoice option that the designer wants to use (say they want set3 today) my 'generic' code has to be something like upArrowBtn(setchoice).scaleY and every instance in the code where that object is used I append the 'setchoice' as chosen by the designer from the external file where (setchoice) is retrieved from something like var setchoice:String = "set3"; from the external file (I am currently abstracting all the adjustable variables to a configuration.as file. I will work on using an XML later when the principle of external files works (I hope!);
Is it possible to import assets from external sources and then use them in the SWF as if they were in the library? The loader class? Is this just fraught with danger I wonder.
Essentially I am being asked to remove as much as I can from the SWF so that if the client wants to change the positioning of things on the stage or the text on buttons or change the style of the buttons or the company logo they don't have to come back to us to ask for a recompile of the SWF for each tiny adjustment. Inevitably SOMETIMES a recompile will be unavoidable (such as if they want the widget to suddenly be twice as wide (i.e. the stage). My code already handles some of this using stage.stageWidth and then positioning objects relative to other objects already on the stage using this value and centred so that just changing the document properties is all I would have to do and everything else adjusts proportionally. I am trying to make this as reusable as possible with as little effort from myself as possible to save our company wasted time.
After all that waffle, my question is this, if I can't load all my buttons and assets and things externally, how do I write the code for this:- I have a library asset called upArrowBtnset1 and another called upArrowBtnset2. Instantiated with say upArrowButtonset1 and upArrowButtonset2 The code would normally be upArrowButtonSet1.x = 100; upArrowButtonSet2.y = 300; but I need it to be upArrowButton(setchoice).x = 100; upArrowButtonSet2(setchoice).y = 300; where (setchoice) comes externally from var setchoice:String = "set1";How does the code change if the (setchoice) string was named not at the end i.e 'button(setchoice)UpArrow'?
ActionScript Code:
var numClips:Number = 5;
for (var i:Number = 0; i < numClips; i++)
[code]....
I need to do something like, getChildByName("mainTab"+i).addChild(myMovieClip) ? or maybe this["mainTab"+i].addChild(MovieClip)?Is it possible without using .name?

I'm just trying to create my small personal website, so I ask your forgiveness in advance if my question sounds stupid...Well, I need to get access to MovieClips instances in my external SWF file, which is a player skin.Although there are plenty tutorials in the Internet about this (e.g. http:[url...), I'm unable to make them work for me...Here is my code:
import flash.display.Loader;import flash.events.MouseEvent;import flash.display.MovieClip;
const SCALE:Number = 1.25;var CPLoader:Loader = new Loader();var ControlPanel:MovieClip;
addChild(CPLoader);CPLoader.load(new URLRequest("ControlPanel.1920.swf"));CPLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, loading_complete);[code].......

let's say character.swf has a movieclip with instance-name "feet_mc" on the stage. And in my main flash-file (not the character but the game) I now load character.swf in a loader and then: addChild(event.target.content); and that visually adds the character to the scene no problem,
but let's say now I want to access the instance "feet_mc" from my flash-file, how do I speak to it?
if I do: trace(event.target.content.feet_mc); < that works! but I want to be able to access it using a real path from the root.
if I: trace(addChild(event.target.content).name); < it will tell me that the name of the character placed on my flash-file is "instance32",
so you would think I should then be able to say: trace(instance32.feet_mc); but for some reaons that doesn't work! why?
I don't want to refere to the loader (i.e. I don't want to gfxLoader.feet_mc) because that one is getting re-used over and over again for all the assets in my game.

I am loading an swf created in flash professional cs5 via the loader class into a flex 4.1 application. The flash file contains multiple movieclips that are exported for actionscript and those movieclips exist in many instances throughout the movie.
Iterating through everything, comparing class types seems to be the most easy but also the most redundant way to solve this. Is there any way of using the class name as a kind of global selector to access the clips?
I could also make the sub-clips in the flash listen for an event on which they perform an action, but I am not really sure what might be best.

(code in code generator movie)
var myaccess:SharedObject = SharedObject.getLocal("Lesson1");
myaccess.data.mycode = pass.text;
myaccess.flush();
Here is my problem, i want to use this created sharedobject on another, separate movie clip, is that possible?Or are sharedobjects just work on their original movie clips?
(code in separate movie)
var myaccess2:SharedObject = SharedObject.getLocal("Lesson1"); // declared a variable for holding the data from
sharedobject to see if it will load the data

I have my main flash, named "front page". Inside of it, I have 2 movie objects that have a time line, one named "About Us", and another named "Button Group". Inside of "Button Group," I've made a drop down menu that can go to a frame on the main page (in "front page") using the _root command. I was wondering if I could go from the front page into the other movie object ("About Us") by going through the main page.
Tl;dr, I'd like to know how to go to the parent of a movie clip and into another movie clip to modify where the time line is.

Main.swf has a button which loads Movie.swf into a movie clip 'contents' (as shown in the tutorials). 'contents' is directly over the button, so when you move your mouse in Movie.swf, it still detects the button in Main.swf.I need to know how to make Movie.swf use Main.swf button so that I can disable it while Movie.swf is open, and enable it when Movie.swf is closed.So far my code is 'blank'.MyButton.enable=false;with 'blank' being main.swf.
