ActionScript 3.0 :: Setting Properties Of Nested Clip From Document Class Of Parent
Aug 29, 2011
Setting properties of a nested clip from the associated document class of the parent clip. I am developing a Jigsaw puzzle in Flash. I am developing a class for puzzle piece. The code of the PuzzlePiece class in given as follows.
PuzzlePiece class
package {
import flash.display.MovieClip;
import flash.events.MouseEvent;
public class PuzzlePiece extends MovieClip {
private var pieceX:Number;
[Code] .....
Is it wrong to access it like that. The PuzzlePiece is the export for a puzzle clip. For the time being I am hard coding the dimension as 60. I have aloso uploaded the fla and as files. [URL].

I have a button function the launches a small movieClip (like a window). Inside this movieClip is your typical keypad.
Code:
package com {
import flash.display.MovieClip;
import flash.events.*;
public class Login extends MovieClip{
[Code].....
I'm trying to next a series of keypad buttons inside the new loginBox instance, so they'll be referenced as loginBox.key1 etc etc.
I want to set their x/y coordinates before they are added to the stage (loginBox.key1.x = 23) , but obviously they don't exist yet.
I'm missing the way to get around this. The very last line of the above code is my hack attempt so far, and it's still causing me problems.
If you have 5 or 6 different components in your library that you want to put inside of eachother from *.as files

I've been working on a project in Flash CS3 for a while. To follow an object on the screen and keep it centered, I'd adjust the Document Class' x and y properties.
Yesterday I bought/installed Flash CS5 and thus Flash Player 10 was also installed. Now when I go play my SWF it seems everything is all buggy, as if the code that modifies the Document Class' x and y properties isn't exactly working properly...
I've since reopened the CS3 FLA in CS5 and converted it to a CS5 format and I can't seem to get it working the way it used to.
Did something change regarding the Document Class and how to modify the x / y properties of it in the Flash Player 10 version? I really don't know what's going on at this point.

I am trying to set up a if function for a hit test. I am using action script 2.0 am coding all in one layer not within movie clips so dont give me code in that format unless nececary.I have a movie clip with instance name src_resolute and I have another movie clip that is nested inside another movie clip named endbar.What I am trying to do is when src_resolute hits endbar I want it do gotoandplay the next scene.The parrent movie clip of the nested movie clips instance name is background.If you need any more infromation let me know but basicly what I want to do is when my main character(src_resolute) makes contact with the nested movie clip(a movie clip I have drawn inside of another movie clip) I want it to jump to the next scene or more specificaly scene 4.

(Actionscript 2 btw - and actually cs4, not that it really makes any difference?) I have a class that instantiates a movieclip from the library, e.g.:
Code:
debugbar:MovieClip = thing.AttachMovie("debugbar", "debugbar_mc", 999);
So attaching it to the where ever "thing" is - could be movie clip or level0 or whatever, doesn't matter as "debugbar" is a private variable of the class. Now the important part - debugbar in the library is a movieclip that contains some components - buttons and textInputs. The problem comes when trying to access these components.
I would have thought that this would work:
Code:
debugbar.input_txt.text = "hello";
In order to set the text of "input_txt", the instance name of a TextInput component on the timeline of the movie clip (put there in author time). However, this does not work. Infact, I cannot access any specific "component" properties - they come back undefined. I can however set and retrieve MovieClip properties for the "input_txt", such as _x. However there is one added strange thing with this too - setting _visible to false doesn't seem to work (however perhaps a component by default overrides this).
I also appear not to be able to add event handlers to the component - at least for the usual component events. I tried casting it to a component, such as:
Code:
var temp:TextInput = TextInput(debugbar.input_txt);
trace(temp);
which gave "temp" as null.
However if you trace the thing itself without casting to what it is, it gives the path to correctly. It almost seems like the components are somehow broken when trying to access them this way - or that they cannot be accessed this way?
The thing is, I was able to access all of this before, when the code to do it was placed on the timeline (frame 1, the only frame) of the debugbar itself, where the components were child instances. This meant I could just reference them directly too - so input_txt rather than debugbar.input_txt , although that is probably largely irrelevant. I need to have it in a class though, as I need to pass in certain objects that need to be accessed by the mc.

when I try to access a property of the document class from another class, I get an error:
Quote:
1119: Access of possibly undefined property _left through a reference with static type flash.displayisplayObject.
Maybe I'm not doing it correctly? This is how I've been accessing document class properties so far. Does the fact that they're private make a difference?

I'm currently working on an interactive app, (site) which requires me to modify a few textfields, and change images dependant on the user choice (using mouseevent). This is a separate module, thus I'm posting the question in here instead:there are three images, that are lined up, with a textbox next to them. When a image is chosen, and enlarges, the text changes with the chosen image, according to XML.The textFields, 'text_title', 'text_description' are contained in a movieclip, called 'textbox'.This has been built in the Flash IDE (CS3) named info.fla/swf, which refers to a Document class 'com.info', made in Flex Builder 3...I attempted to modify the textfields using this:textbox.txt_title.text = "Loading";textbox.txt_desc.text = "test";But, I was unable to at first to change the text using the document class, as it gives "1120: Access of undefined property <variable>".

1. When I place all movie clips on the same main stage, the xml file can be read perfectly. BUT not reading properly inside nested movie clip. Is it possible to read XML object in nested movie clip in the first place???
2. Is it better to load xml document just once in main timeline, and then read the XML object from movieclips OR read the XML document for each movie clip? Which way is better???

Ok im rather new to flash so ill do best i can to describe this. I have a HealthBar movie clip with 3 layers, bottom layer is just a red rectangle, middle layer is a green rectangle that is a movie clip, and the top layer is just a border. the green rectangle movie clip has an instance name of bar. i put my HealthBar on my stage with an instance name of healthBar and i change it when the players health goes down by calling _root.healthBar.bar._xscale = health where health is 0-100.
this works all fine and dandy. now i have a movie clip of MiniBoss with an instance name of miniBoss# where # is a number of the layer depth when it is created. in the MiniBoss movie clip i have an instance of the HealthBar with an instance name of bossHealthBar. i tried to call from within the MiniBoss class bossHealthBar.bar._xscale = health but i get an error that there is no property of bossHealthBar.bar._xscale. how do i access the bar in the HealthBar in the MiniBoss clip from the MiniBoss class in its onEnterFrame() method?

My player movie clip has a smaller movieclip within it. Because the smaller movieclip is not within the parent clip it changes the x,y,width,and height value of the player movieclip and throwing everything off! To adjust I have to add (-2ndmovieclip.height) to everything i want to do. This is sloppy and I don't like it. Is there a better way to have a child within a movieclip without it affecting the parents properties? i want the parent to keep its original x,y,width,and height properties but the child keeps adding to them!

I have 3 dynamic textfields that are added to the stage through an external class, (I only add the main container from the Main.as) the textfields are nested under 5 MCs (that's what i see when i list objects in the debugger) how can i access those textfield from the Main document class?I've tried by path, by getchildbyname, i've exported the font for AS (the textfields have instance names)... and nothing works, i either get an error or it tells me it has no properties, or null..

I am building your standard slideshow flash header for a web page.
There are three main parts:
The Slideshow class A controller class that is used as the projects Document Class Some linking timeline code.
The slideshow class has all the functionality, so I used the Document class to create a new instance of the slideshow and keep a property variable called slideshow that keeps a reference the Slideshow instance.
import flash.display.MovieClip;
import flash.events.Event;
public class Header extends MovieClip
{
[Code].....
Despite me being able to call regular methods that are in the Doc Class from the timeline, I can not call properties without the following error, for example when i say slideshow.play():
1061: Call to a possibly undefined method play through a reference with static type com.example.test:Slideshow.
I have to make a method on my document class every time I want to wire an event to call an object in my Document Class?

I have a class linked with a movie clip, and in this movie clip I want to be able to add an event listener that calls a function in the Document class (the class you link with the fla as a whole). How can I do that? Say the name of my document class is KPScript.as. In my GameController.as class, I want to listen for key input and call pageChange() in KPScript.as when it gets called. Would I have to import KPScript.as into the GameController.as? If so, I wouldn't want to create another instance of the KPScript object.

i've got an inheritance chain of AS2 classes set up where i have an array in the 'child' class that i'd like to be able to access from the 'parent' class:
bottomClass.as -'parent'
topClass.as -'child'
my question/dilemma is: how can the parent access the properties of a child class...is this even possible, or am i just looking at it wrong?

I'm using a PreLoader as a parent SWF that loads the actual website as a child SWF. In the website SWF, the child SWF, will MovieClip(root) still work and refer to it's own root, or the PreLoader's root? And would I still access the websitite's document class (the child's document class), through MovieClip(root)? What if both files have a document class?So my main question is how do document classes and MovieClip(root) behave in the scenario when you have:
Parent SWF - document class, MovieClip(root)
|
Child SWF (loaded by parent) - document class, MovieClip(root)

I use the loader class to load in an external swf, a preloader movie in my class. (not a document class)
To target the properties in the swf (specifically the text field in it), I coerce it to a movie clip after it's loaded and add the child with:
var thumbPreloaderMC:MovieClip=evt.target.content as MovieClip;
now I can use:
thumbPreloaderMC.preload_text.text "sometext";
to reach the text field. works.
But, I want to nest that clip in a container movieclip I'm placing all the thumbnails I'm loading in, thumbContainer.
So I create the movieclip thumbContainer, add the child, then add the preloader swf to this clip.
I can't name the loaded swf, it throws an error, I googled that and see I can't name an already named clip.
I get an error "TypeError: Error #1010: A term is undefined and has no properties."
First of all, I'm fairly green with as3 still, I think perhaps I should rethink how I'm structuring this. I could and would ask how to target a nested loaded swf from a class.
is nesting clips like this from a class bad practice? What are best practices when it comes to using timeline based animations like preloaders etc by a class? I'd like to make my class as reusable as possible, but one can't create all animations and graphics from code.

I'm trying to call a function called checkForHit() located inside of my Hero class at a particular frame of an attack animation of my Hero object. Meaning, when his weapon is at the point in the animation where it could collide with any enemies, I want to call the function that performs the check.My Hero Movie Clip is set up where it contains a Movie Clip on different frames that coorespond to the different animations (attacks, movements, etc). So the Hero MC contains a bunch of other MCs. That way I can just use hero.gotoAndStop("attack1");
The problem that I'm having is that the code that I wrote to call the checkForHit() function is written on one of the frame of the nested MC's timeline, and it's not being recognized. In fact, even if I put a trace("HELLO") on any of the frames on the nested MC, it's not being output. I even tried to put something that I know should cause an error on one of the frames, and it ran without throwing an error. It's almost like the code on the timeline isn't being compiled, or it's being skipped over somehow.

i know this may seem kind of dumb, but how does one access the document class from a child movie clip on the stage?
i have a property in my class. Just a string for testing:
Code:
public var s:String = 'can you see me';
it traces on the root time line, but it errors out if tracing it from a movieclip on the root time line.

I have a FLA (say Main.FLA) document class with a child MovieClip on the stage: into the child MovieClip I load other swf files: each of the files contains its own Document Class (every swf is a somewhat independent application, say quizzes and so on).For some reason I must use the Main document class to store data (scores or so) from the child swfs loaded into the Main swf. HOW do I reference the Main class? I can't find a way.[code]and dispatch an Event this way from the loaded swf document class to the Main class:[code]Now, first of all I don't know if this could even work. Secondly, I tried to make it work by adding an event listener to my Main class but id did not work.

I have one movieclip object with a custom class.
That class has a loop that creates / instantiates a number of copies of another movieclip from the library. This second movieclip has a textfield child in it. When I convert this textfield to a movieclip I can access the properties of it fine, but just as a dynamic textbox I can't access it.
This is the custom class of the second movieclip that gets instatiated a few times by the first custom class...
This custom class relates to a movieclip that has a child MC called recent_text (which I can access ok) and in that child is another child (a dynamic text field called "aDynamicTextBox", which I can't access)[code]...
