ActionScript 3.0 :: Protected Set Functions - Cannot Access From Child Classes
Feb 20, 2009
I have this function in the parent class:
ActionScript Code:
private m_colors:Array;
protected function set colors(clrs:Array):void {
m_colors = clrs;
}
Then, in my child class I want to call this as:
super.colors = [15, 255];
But it throws an error, it says:
Ambiguous reference to colors. If I do the same with a common function, not a setter one, then just calling it with its name in my child class works fine.
I've seen some discussion on how to load a child swf using swfLoader and accessing it's variables but I am wondering if it is possible to do this without adding any code to the child swf.Either accessing public vars or listening for funciton calls would work fine
I'm coding a small flash game, and wan't to access different functions between classes. In C# I'm used to just making it static, but I'm having some problems with it.Here goes:
I have a menu movieclip that has several buttons, each with listeners writtin in the movieclip's actions layer in Frame1. The script goes something like this:
why (in this example) the use of a protected functions is required. It is an Adobe example showing an audio mixer board.I included just the code of the main document.
since i started using Flash Builder (Flex 4) i could see that it can auto-generate some handlers for example if i have a <s:Button> and i add a click="" i get a hint of "Generate Click Handler" and when i click Enter he writes this code:
Code: protected function button1_clickHandler(event:MouseEvent):void { // TODO Auto-generated method stub }
Now i knew about public and private things(functions/vars) and if a function was public i could execute it form outside of the class and inside. But if it was private i could only execute it from inside of the class and i couldn't execute it from outside of the class.
So anyway, what does "protected" mean? what does it do?I was thinking that if i load a SWF in my app I can go inside of that SWF and execute functions, read values from variables, or anything like that ... and that seems like a security problem ... So i was wondering if the "protected" keyword could help me with this security problem. And if not, I would like to know what is it good for
Let's I have a class Square that has a several functions. I want to call it from a class Grid, which is a group of Squares.So in the class file for Grid, how would I do this:
Code: public function doSquareFunction(thisFunction:Function):void{ square1.thisFunction();
Assign an event listener to a protected timer variable in the parent class.
I am working with Adobe LCCS, and created a BatonProperty which implements Baton
Now, Baton has a protected timer variable declared like this, and for some reason, I am unable to get access to this _autoPutDownTimer, from a BatonProperty instance.[code]...
i have problem with swfLoader in flex, when i close following code in click method i can easly add many swf to main application
<mx:VBox id="content" width="100%" height="100%" ></mx:VBox> public function doIT():void {[code]....
when i close adding those swfs in loop i have the same error, it looks like child apps couldn't access certain objects that were instantiated by another child app, so what can i do?
i'm trying to figure out how i can handle login protected actions in RoR (Ruby on Rails) with Flex without using weborm or rubyamf remoteobject.I'm in the situation where i have to fill a datagrid with results of an HTTPService request after i log in correctly into my application. Can anyone suggest me the way to accomplish that?
so I'm having this problem where one of my classes can't locate a function. The function it's trying to use is in another class, so I was wondering if there was something special you had to do. This is what I'm basically doing: One class
I have a mainSwf in which I load an external swf, which loads an external swf.( a child of a child). I am trying to set the framerate via AS3 for the childs child by using stage.frameRate= 15;
It doesnt work when the children are loaded into the mainSwf. how to access the stage of a child's child? I have tried root, Movieclip, this but can not get it to work
Let's I have a class Square that has a several functions. I want to call it from a class Grid, which is a group of Squares.So in the class file for Grid, how would I do this:
Code: public function doSquareFunction(thisFunction:Function):void{ square1.thisFunction();
I have Flash project that is set up something like this:
myProject.fla
- document class = myMenu.as
- the document class imports a menu item from menuItem.as (import menuItem;)
I have a function in myMenu.as that sets the text formatting for all the text fields on the page. I want to be able to use this same function in menuItem.as so that all the formatting is consistent & you only have to change it in one place. How do I access this function from both myMenu.as & menuItem.as?
okay, i'm refactoring a huge ActionScript file, and so trying to move some functions into their own classes. why is this not working? i've got a function in my primary class:
// ... private var testBlock:Sprite; public function testingINT() { testBlock = new Sprite();
This probably has a simple solution, but I'm a complete newb to actionscript and I could really use some guidance.I have a file, called Politismos.fla. The document class of this file is: com.plaidfox.PolitismosClassPolitismosClass.as is as follows:
I've been working my way towards better OOP design lately and I've come across a problem with accessing functions in other classes from my Main class. Here is the code:
They are listening for functions that are within the Player.as class, these functions control the dynamics/movement of the player itelf. But for some reason I'm getting a 1120 error(access of undefined property). Basically how do you listen/access for functions within a different class?
asically I have a Player class with methods (i.e. Moving the player) that I want to listen for and implement in the main class. To put it simply, I'm creating the player methods in the player class and then calling them in the Main class. But for some reason I'm having some trouble, I'm still trying to get used to all this OOP design.Here is the (Main) code, it's not alot:
in my Main class, i try to call a function from another class, but when i compile i get this error:1136: Incorrect number of arguments. Expected 1.i have seen some fixes involving an event in the OtherClass and (null) when i call it, but it dosent seem tohere is a code that describes my problem, what do i have to do to make this kind of code work?m i doing it wrong, or do i have to do something else?OtherClass
I was wondering if ActionScript had some way to call functions and classes from variables, like they do in PHP:
function funcname() { print "Potatoes come from tree"; } $function = "funcname"; print $function; // Prints out "funcname" $$function(); // Prints out "Potatoes come from tree"
In case you don't know the syntax for PHP, you should know that anything perpended with a $-symbol is a variable.
I have a flex application that loads swf files and displays them using the SWFLoader object.is there a way to provide different classes and functions for the swf application to use? [code]...
I have a Flash application that creates a sort of powerpoint presentation. All the 'slides' are stored in an XML files which is read and processed.
I'm trying to build the presentation using this XML file. At the moment, my main class has it's initial function main and a static function processXML main initiates my database class with a function called initDB. One of my issues is that initDB forgoes processing because it's dependant on an event listener. On completion of loading the XML files, the event listener initiates my static function on my main to create objects from this file.
The issue is that because the event listener continues the processing (after an indeterminate amount of time), the functions are no longer controlled by the main class.
I'm new to the object oriented stuff and I'm trying to learn how it works. Here's what I've started on - it's led to a few dilemmas. I have one flash file and two .as each with one class. In the timeline of the fla file, it reads: ActionScript Code: var FileObject:ScriptFile = new ScriptFile(); function onEnterFrame(){ FileObject.CallInput(); }
Call input is a function in "ScriptFile.as" that calls another function in "Input.as"; ActionScript Code: class Input{ public function Input(){ } public function keyListener(target:Number):Number{ [Code] .....
In output, when I press Left, it will say -5 over and over again, and I'm trying to add to xpos value but that isn't happening.
Im trying to load some data, but I want to outsource the job of data loading to different classes.lets say XMLLoader class will get the url and return an xml file. The problem now is that such procedures are asynchronous, the class has to wait for XML to load and then call back the caller class and return the xml data.One way of doing this, is returning the data with a custom event. once its loaded then dispatch this event with the data in. However, I was wondering, if there is a way to do it with some sort of asynch call, meaning the caller class sends the request, then waits for a response.is such a thing possible? is there a better way or do I need to stick to my custom events?
I have a rather general question regarding OOP. How do constructor functions execute with multiple class extensions? I'm making an orbital physics simulation, and every spatial body is of the class SpaceObject, which extends Sprite. Then, I have all earth-type planets be of the class Earth, which extends SpaceObject. There are certain parameters that I'd like to set for every single SpaceObject (like position and size) in the constructor function, and certain parameters (like density and mass) that I'd like to set in the constructor of class Earth.But from the main timeline, when I create an instance of class Earth, I can only enter the parameters of the Earth constructor, ie
Code: var planet1:Earth = new Earth(density, mass) Or I can create an instance of SpaceObject:
For some reason I can't get this nested set of functions to work, it executes the first tween and the tween invoked after motion of the first is finished but it doesn't ever get to the third!
ActionScript Code: var t1:Tween=new Tween(p1,"rotationY",Strong.easeOut,90,0,50,false); var t1x:Tween=new Tween(p1,"x",Strong.easeOut,-900,0,50,false); t1.addEventListener(TweenEvent.MOTION_FINISH,onMotionFinished);
