I make classes that extend movie clip, but I want to dynamicaly create instances of this class, so I really create MovieClips, but with the added features of the class. How should I create this instances? I want 'this' to be the root of this new movieclip with added features

View 4 RepliesI'm trying to create a series of scripts that will create some custom event listeners. I have three movie clips on my stage. One is a movieclip who's sole function is to hold array's and the event listeners. A second which moves around the screen. And a third that is motionless. The problem is that the argument I want to test (which activates the custom event) is held within a string. What I want to know is, how do you test to see if the string argument is true?
Is it something similar to this:
var myCode:String="1<0";
if(myCode){
trace('one is smaller than 0'); //Strangely apparently one IS smaller than 0!!!
}
I think I'm going about this in the wrong manner, however this is the only way I can think of this working... (since I need to be able to dynamically create these events).
I have a designer who has created a set of movie clips that I want to create instances of using ActionScript, but all I have is the name of the MovieClip as it's stated in the library (not the instance name).
Is there any way to create instances of the MovieClips using just their name? Or do I have to create separate classes for each?
I've been trying to create a simple loader class that loads an image file onto the stage.
Writing the code to perform the task is simple via the main timeline:
Code:
var picloader:Loader
picloader = new Loader()
picloader.load(new URLRequest("photo/1.jpg"))
[Code]....
How should I write the class such that it performs this function? Ideally I would like to specify the file I want to load eg. loadimage("photo/1.jpg") when I run the method.
how to create custom event from beginning to end in AS3?I'd like to know how to create a custom event that extends the Event class and then how to dispatch it. Also, I'd like to know how to catch it using the addEventListener() in the format Event.ENTER_FRAME or Event.CHANGE etc...
I'm having some difficulty understanding how events work. I believe "ENTER_FRAME" is a constant holding some value but I don't see how that could dispatch an event. From what I understand; ENTER_FRAME is a static variable of the Event class?
I have made a site in AS3.0 code and it's working fairly well but theres alot of things i'm trying to update to make the code a little more reusable. For startersI have a function that creates a little pop-up text when I roll over a button. The text is a class that I created in the Flash IDE instead of dynamically drawing it with actionscript.Here is the code for the pop up text instance called "enter_text" as it rolls over the movie clip "preloader_mc"
Code:
//add listeners to the preloader_mc movie clip on stage
preloader_mc.buttonMode=true;
[code].....
I have a custom class which creates a new MC using a library MC. The library MC contains a dynamic textfield called productName.
The custom class object gets created fine and is displaying on the stage. It's also holding custom properties I set as well.
How do I control the dynamic textfield inside the MC, which is inside the custom class object?

Code:
package {
import flash.display.MovieClip;
public class Product extends MovieClip {

I have a custom class that animates a set of movie clips. Something like coverFlow or Carosell. What I want to do is pass a array of all the movie clips to be used by the class. I am not sure an array is the best solution but it makes sense to me. The class will not always know how many movieclips are being passed so with an array I can get the lenght and deal with it. here is the instaciation code of my class mBack and mFront are movie clips on the stage.[code]I get this error Type Coercion failed: cannot convert flash.display::MovieClip@113d2061 to Array.it kinda of makes sense why I got the error but if this is not correct how do I pass a list of mc's to my class.
View 5 RepliesAfter resolving one issue, another error has surfaced in my custom class. This class displays a dialogBox and the dialogBox has some interactive MovieClips like btnOK_mc Button.On creating an object of the said class, it reports errors like "Access of undefined property btnOK_mc".[code]I understand that it is an issue of the Scope of these controls; but don't know, how to define these MCs; so that they look like Public. I may be just out of track on the issue.
View 8 RepliesI would like to make a new instance of a MovieClip within my library from code written in my keyframe. I relise that you can do this by making a class and using the codeCode:var instancename:movieclipname = new movieclipname(); and with the MovieClips class I would need to extend MovieClip and nothing else. I am unsure if you put in the name of the MovieClip or the name of the MovieClip class in the code above so feel free to correct me. But instead of doing this can I just add a MovieClip to my stage with doing this
View 4 RepliesI have a problem that seems easy enough to solve but I'm trying to do it with reusable code, which involves doing something I don't understand yet. I've googled this endlessly and read dozens of articles and I'm still just as lost as when I started. I'm hoping a live human being can help me make sense of it.
I have a movie clip on stage. When this movie clip is pressed, I want it to play a certain frame of another movie clip for as long as it's being touched. (It's a map of the US, that will display each state name as it is pressed.) I COULD write 50 different functions, each to call a different frame of the displayName movie, or I could write my own custom event that would be able to receive from each touch event a string variable to then tell displayName which frame to play. So basically, I have, for example:

I had watched a CartoonSmart Tutorial on AS3, and the amount of code that goes into a button seems to much (especially coming from AS2). I tried to create a custom class to make my life easier for this, but... I ran into a snag.
Errors:
Code:
1046: Type was not found or was not a compile-time constant: MouseEvent.
I receive that error 4 times in these locations.
Code:
function ButtonClick(event:MouseEvent):void {
function ButtonRollOver(event:MouseEvent):void {
function ButtonRollOut(event:MouseEvent):void {
function ButtonDown(event:MouseEvent):void {
Here is my button_class.as file.
package {
public class button_class {
function button() {
}buttonVar.addEventListener(MouseEvent.MOUSE_UP , ButtonClick );
function ButtonClick(event:MouseEvent):void {
I am using Flash CS3 Professional. And when I have the class put directly into the main time line ( Copy and paste) It works perfectly, but not here.
I have the following as code in a separate file placed in the root folder of the swf file. The as file is the class for a MovieClip in the library.When i manually place the library symbol on the stage, the MC works fine and draws the square with the nodes. However, when I try to create a copy using ' new sqMC();' code, I get an error.
Code:
package {
import flash.events.MouseEvent;
import flash.events.Event;

I am new to AS3, as well as Flash in general, so forgive me if this seems highly elementary. All I am trying to do is create a custom class that extends the MovieClip class and contains a custom property of "marker". I want to be able to use and change the value of this custom property on the timeline for an instance of this class and have it behave just like any other (Ex: this.x ==> this.marker).

I have a custom class being constructed from my main class. In the custom class it has another custom class that is passed in as a parameter. I would like to strictly type the parameter variable but when I do, 'the type is not a compile type constant etc'.This, I understand, is because the custom class used as a parameter has not yet been constructed.It all works when I use the variable type ( * ) to type the parameter.I suspect this is a design flaw, in that I am using an incorrect design pattern.It is actually hand-me-down code, having received a large project from someone else who is not entirely familiar with oop concepts and design patterns.
I have considered using a dummy constructor for the parametered class in my main class but the passed in class also takes a custom class (itself with a parametered constructor). I am considering using ... (rest) so that the custom classes' parameters are optional.Is there any other way to control the order of construction of classes? Would the rest variables work?edit)in main.as within the constructor or another function

This is my first time working with a class attached to a movieclip that is nested inside a class attached to a movie clip.I've tested all the properties and methods of PTListItem.as and they work properly but when I try to call them on the list item through PTListTop.as it returns undefined.The end goal is to dynamically load a checklist via a txt file.
View 1 RepliesI have the following situation:I have an event handler, that displays small messages in my application's statusbar.These messages get passes through by dispatching events from custom components.A simple message could be like "HTTP Error" or so.Now, the main event listener, in the main application file, listens to the event dispatched by any custom component,but seems to refuse listening to events dispatched by custom AS classes.Here is my code for the custom event:
package main.events
{
import flash.events.Event;[code]..
So to sum it all up:
- The event listener listens to the custom event dispatched by any custom component.
- The event listener does not listen to the custom event duspatched by an AS class.
Those who wonder, the event really gets dispatched, that's why I added a trace call.
I couldn't work it out yet...
package components {
public class templateSelection extends VBox {
static public var tempSelectionBag:Dictionary;
[Code]....
I want to have a custom class tempSelection with a Dictionary as a public accessable property of that class. If I use this code, the compiler tells me:
1046: Typ wurde nicht gefunden oder war keine Kompilierungszeit- onstante:Dictionary
Which translates to:
Type was not found or was not a compile-time constant: Dictionary
If I have a Document class that extends MovieClip, and I want to use it as the basis for another Document class, is it possible to create a subclass that extends the main document class and use that for a different FLA?
For example,
fla1.fla has a document class of MyMainClass:
public class MyMainClass extends MovieClip
fla2.fla has a document class of MySubClass:
public class MySubClass extends MyMainClass
I've tried, but now I'm getting errors that all of my variables that reference stage instances aren't being found.
I have a custom class created by a main document class, and I want the custom class to run a function in document class after some time.
How can I sent the instruction from custom class back to the document class?[code]...
get a bunch of objects in my library to inherit from (or even be) one class that i have made, but without having to make .as files for every single one is this possible, or is there any other way to give objects another classes functionality in an auto-generated class?

I'm trying to create a class which will create a tween for several different instances of an object. I am creating the instances in the Document Class. The trick is, I would like to specify how long each tween will take.
Here's what I have so far:
DOCUMENT CLASS
ActionScript Code:
package {
import flash.display.MovieClip;
import mcCloud;
[Code].....
As you can see, I have a variable "myTime" which syncs the timer and the tween. This causes to tween to repeat and the clouds to continually scroll across the stage. How can I determine the var myTime at the time I create each instance of the Movie Clip mcCloud?
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 {

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.
the website I'm work on has the document class Main. Within this website I have a movieclip on the stage which I built a custom class for its functionality and I linked this movieclip to this class to make it work. There is no reference to this movieclip or class in Main.
Now, I need to communicate between these two classes. Can I do this? Can I dispatch an event from the custom class linked to the movieclip and have the document class listen for an event? How?
Is there a point of creating custom event class if i dont need to pass custom property with that event?
View 3 RepliesI have a document class called Main.as In the class constructor I have the following listener:
enter code here
var listeningFORModeChangeToStudent:Sprite = new Sprite;
listeningFORModeChangeToStudent.addEventListener(TellAllModeChangeToStudent.STUDENT,exp);
addChild(listeningFORModeChangeToStudent);

In a third class I make a call to the despatcher in the previous class:
enter code here
var ThisTellAllModeChangeToStudent:TellAllModeChangeToStudent = new TellAllModeChangeToStudent;
ThisTellAllModeChangeToStudent.tellAllModeChangeToStudent();
I have trace statements in eveything and from this I know the despatcher in TellAllModeChangeToStudent is being called.The problem is that the listener in the main.as is not calling the function exp.I cant see why and I dont know how to check if the listener is actually seeing the dispatch event?
I understand it's probably best practice to name your custom classes differently than the built-in AS3.0 classes; however, what kind of problems could I run into if I don't?Specifically, I have a class which, ideally I want to name DataProvider. But, as you know, there is already a DataProvider class on the Flash platform (used for list-based components and such).Now, I don't think I'll ever use BOTH of those classes, so I'm assuming as long as I reference the correct DataProvider class in my import statements I should be ok?What if I DO need to use both, is that even possible?
