I have a class1 in which I create a child from a class 2. Of course I can access class2 properties, fields and methods from class1. But is there a way to access class1 fields and methods from class2? Like to go a step back in the hierarchy?
View 1 RepliesI'm currently working on a tower defense game and am in kind of an odd situation. I've programmed it in such a way that a large class hierarchy is in place. It's like this StartScreen class ---> BaseLevel class ---> GUI class ---> TowerPlacer class(towers are stored in an array in this class) ----> etc.My problem is that i need to access an array in BaseLevel from my GUI class, is there any fancy trick for doing this? or have i screwed myself over.
View 2 RepliesI 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.
View 1 RepliesIm making different quizes and small games. I always use a Document Class when coding, and usually i call this Main.as. Usually the Main.as contains pointers to different classes like:
private var _menu:Menu;
private var _messageBoard:MessageBoard;
etc..
My question/scenario is this: In for example _menu, i have a button that has an event listener on it (example: "Start" button). When this event is triggered (ie user hits "Start") I want to trigger a function in Main.as. How is the most elegant way of doing it? The solution i use now, is that i send a reference pointer of Main.as to each new class i make. ie in Main I would do something like this:

I m new for OOP concept see this is my class, How this class will return values???

I'm new to AS3. I've got two classes.
damnMoles.as and startBtn.as
The damnMoles class uses a method called randomPlay();
ActionScript Code:
public function randomPlay():void {
this.gotoAndPlay("moleLabel"+randomNumber(1, 18));
}
Which basically allows the looped mole animation to start from various points in its timeline. I could probably use a different method to do this using an interval variable, but I originally coded this in AS2.0 and I want to update it, to see how this are different.
damnMoles class is attached to 6 mrMole# instances on the timeline.
Originally I used code on the main stage timeline to start the animation of the moles.
ActionScript Code:
startBtn.addEventListener(MouseEvent.CLICK, startClick);
function startClick(event:MouseEvent):void {
mrMole1.randomPlay();
}
This works fine, however, I would like to refrain from timeline code and use .as files. My startBtn class looks like this, but I get the error:
1120: Access of undefined property mrMole1.
ActionScript Code:
package com{

What if you have methods you want to use in your project, that really have no need of a class, or in other words, there is no need for an "object" associated with it. It's not going to have member variables, so why bother making it a class?
for example,
I want to create a randomNumber method, takes two numbers, low high, returns a random between or equal.
Originally in my code I had a very top level class i just called globalLibrary that extended movie clip, i put my randonNumber method there. Then every class in the project extended that. I got the method scoped properly, but to me it looks like a hack.
For example, the most basic functionality in flash like +, even = , trace, etc. Are these also methods defined in some class that we are extending? Or are they methods that have no object associated since that would seem to make just as much sense.
why can't I just create a file of methods, and import that file and have access to these methods?
SETUP: I have a MX2004 project where I'm attempting to pass a movie clip to a class, and have a method of the class act as the function for the onEnterFrame. PROBLEM: The class appears to lose reference to the movie clip when onEnterFrame() is called. TO DUPLICATE: Two files are needed, they are outlined below:

I need a way to reference to object (or the class methods inside). I have a button "Add box" and when it is pressed it creates a new instance of class "MyBox". The thing is everyone of these objects get the same name "box".Here's a hint of what it's like:
Code:
var arrBoxes:Array = new Array();
// var n:Number = 1;[code]...
Inside of the addBox function I can easily refer to the Object with just "box" (for example box.name = ..)but when in another function I cannot (and by then I might have created many "box"es).
If i instantiate class B (not a display class) in class A whats the best way to call some methods in class A from class B ?
View 3 RepliesIs there any way to add methods to the existing MovieClip class so that later I can use them everytime I instantiate a MovieClip? Something like this:

View 1 RepliesHere is the situation:I have created a movieClip named "tp_crack" on the timeline and created its class using linkage called "tp_crack".The tp_crack mc is like a small rectangle which breaks in 3 seconds when it is played.I have a seperate class in which I have used tp_crack to create many instances of tp_crack going by the names: cracked1","cracked2" etc.These instances are present in another movieClip (this time created within the class) called "crackContainer".Now I have added the following code to check for hitTest of those cracked1,2,3...... with a spaceship.The hitTest works but flash does not recognize the pieces as movieClips and does not play them as required, instead it gives me an error saying:1061: Call to a possibly undefined method play through a reference with static type flash.displayisplayObject.

I have this base class

TypeError: Error #1006: updateText is not a function.

Why doesn't it work? I know the class is read and compiled, because I had an error there which was reported.

I want to add a custom method so that any MC can use it like this - Code:text1.fadeIn(2) - which would fade text1 in over 2 seconds. The actual method isn't important, it's the way to add it as a custom method for ALL MCs that is confusing me.I can add it inside the document class (that extends MovieClip) like{/*fade in over tt seconds etc*/};But pretty much everywhere I look peoples are choking on their coffee shouting not to use that method. So is there a nice, clean way to do it without using prototype?BTW I want to add these methods in a class that is imported into the main document class at compile-time. So my main doc class has code specific to this SWF but the general external classes like Effects and Transitions are imported as needed.

View 9 RepliesI've got a custom class (using AS2) that mostly does things like set the score and level of a game, as well as sets the player's lives on the screen. I need to unload and attach MovieClips within the Lives control function, which require those methods from the MovieClip class. I don't think I need to extend this class from the MovieClip class, I think I need to import the class somehow. I don't know the path though..something like mx.MovieClip.

As the "Math class" is static internally. We know why we can not add custom methods n properties to every class, as the way we do in AS1.

Let's say I have a FLA file with document class called main. In main, let's say I have a method called test1 that just outputs "hello world" via trace. On the FLA I have a movie clip. In that movie clip, when the timeline reaches frame 123, I want it to invoke the test1 method (I just set up a simple action on the frame). However, I get an error saying that the method is undefined. I try this.parent.test1() too but that gives me the same error. Is it not possible to invoke a document class property from within the timeline of a movie clip that's on the stage?
View 2 RepliesI'm trying to access an init method I've set in one of my document level classes.
Container Movie loads Main Movie, which has Main.as as its document class, but I want to do a few things before I show the actual content. Here are some functions in Container.as:
Code:

loadTxt.visible = false;
var logoMoveUp:Tween = new Tween(logoCont, "y", Back.easeIn, 221, -250, 1, true);

I've got a class (say ButtonBase) that extends MovieClip. ButtonBase has a method that names it ((this.)name = 'bb1') and adds it to the MainTimeline. Now I can see my extended ButtonBase MC on the MainTimeline. And if from a frame I write trace(this['bb1']), it returns an instance. The problem is that the instance is not recognized as an instance of ButtonBase. Suppose ButtonBase has another method, say testMethod(). Well, if I trace(this['bb1'].testMethod) from a frame on the mainTimeline, it returns undefined. If I trace(this['bb1'] is ButtonBase), > false I can attach a fla if you need it.
View 3 RepliesMy question deals directly with ActionScript 3, although it could possibly appear in other languages. Consider the global trace function found in AS3. Calling the method requires no imports and is globally available from all classes.
class A {
public function A() {
trace("Hello, A!"); // Hello, A!
}}
Now, what if I create my own class method of the same name? In AS3, if I have a class method trace and then make a call to trace elsewhere in my class, the call is made to the class method over the global function. Essentially, I've blocked my ability to call the global trace method.
class B {
public function B() {
trace("Hello, B!"); // no output
} public function trace(s:String):void {
// do something else.
}}
Now, I know the obvious answer is to say, "don't create a class method called trace." But what if I'm unaware of the existence of the global trace function? Or what if I have a desire to "override" or "block" the global function? Is doing so bad programming? Or is this just another example of how AS3 is a poor object oriented language?
