ActionScript 3.0 :: Return Variable Between Classes?
Jan 21, 2009
I have a problem with returning variable between classes. As far as I know there are some ways to do it but in this particular case I tried to use Getter.
So I have an XML file (content.xml), a class to read XML (LoadXMLExt.as), a class to display images, and the main class which first call the LoadXMLExt to get the information from and then call the displayimage class including passing the information from LoadXMLExt.
In script below I want to pass the String received at function WhichPage to function Adder which does not get triggered till user interaction. I know I can store the String (page) in a global variable but wanted to know another approach to this. Can request the value from the WhichPage function or get to send it to the Adder() function without triggering it.[code]...
I am trying to make a hangman game and have made an array with words and picked one at random each time the movie is run and then taken that word and broken it apart into each letter. I then made a loop to create a new TextField for each letter. Then I set them all to "visible = false"I want to get to the point where if the user selects a letter that is in the word that that TextField with said letter will become visible. Only I cannot figure how to get a function outside of the loop to see the variables (i.e. instance names of the TextFields) inside the loop.Here is my code:
ActionScript Code: var words:Array = new Array("HELLO","WORLD","JOE MAMA","ALIENS","ATTILA"); var letterArray:Array = new Array();
create and send a variable called "return." But that conflicts with a word used in actionscript.[code]is there anyway to work around this naming conflict?
First of all sorry im not very familiar with the flash lingo, im still new to all this actionscript stuff
ok so i wrote this on a frame in the timeline[code]...
now i need to check which one from all these has a value of zero. then when it finds it i need it to tell me which one it is (s1x or s2x or s3x) so i can do stuff with it.
I have a function inside of a class which is called by an event Listener I need access to a variable inside the function after the eventListener has been called. The variable name i need is stream and the function it lives in is called NetStreamxx. I tried to return stream but i don't know how to access the returned value here is the code
I am trying to implement paypal payment in as3. But the return variable conflicts with an as3 keyword. So how to set return variable for returning from paypal to merchant site.
I was just wondering if this is possible and the best way to achieve the following.I have 3 classes. One base class and 2 subclasses. eg MyShape, Square, Circle. The Circle and Square classes both override the MyShape's assignProperties method which takes a string as its argument.What I do in this method is loop through a serialized string and assign variables.So the string looks something like p:10|x:200|f:300Because some of the properties are generic to the MyShape class I have the Circle and Square assignProperties call super.assignProperties()Now this all works great but I realised I'm going to get some repitition calling it at each level.
So I was thinking is it possible to get the supers.assignProperties to strip a property from the string if it is found before the assignProperties in the Circle and Square class is called.Here is sort of what I have with a little pseudo codeSquare Class assignProperties Method
PHP Code: assignProperties(_properties:String) { var properties:Array = _properties.split('|');
I have two classes, IntroScreen.as and MainMenuScreen.as.I have an input text box on the IntroScreen that captures text and successfully traces it in the same class.
Actionscript Code: public var nameEntry:String;public function startButton(event:MouseEvent):void { trace("Start button clicked.") nameEntry = enterName.text;
I've got two classes running...one is a document class (EgoGame.as) and another is a class linked to several similar movie clips (Ball.as).I'm trying to access a public variable from Ball.as which has been declared in the doucment class EgoGame.as.When I run the test the outputs states the following...1120: Access of undefined property _ballPlaced.Here's my code. What I'm trying to do is remove the event listeners from the Ball.as when the _ballPlaced variable is true, so that the user can't drag and drop the balls after they've been placed in a zone.
I'd have thought this to be simple, but nothing works. I have a game I'm working on, and in it, there will be a speed stat. The fast you are going, the faster everything else has to move to make it look like you are moving faster.The problem is, the speed stat (obviously not called speed) is one of the upgradable stats, and needs to be available for the class handling upgrades for it to be changed, and it needs to be read by the class handling moving objects.The second class however, has absolutely no idea the variable even exists. I've tried for weeks to look up a tutorial on it, but there doesn't seem to be any at all that I can find. (I am using public variables, and have tried various ways of trying to point at the class it's from but apparently I must be using the wrong syntax)
I need to pass a boolean variable initially set to false to one of my classes called "EasyGame".It is than changed to true when one of the function in this class is runned.
What I want to do is pretty simple but I must not know how to do it. I want the URLFactory to create the Array and store it in the variable "dataArray" and use the Array in the Main class by calling the GetList() of the URLFactory class. What I have returns nothing...
Basically I need to set a variable equal to URLLoader.data (var something:String = URLLoader.data) so I can use this variable in other classes.
AS3 says you need to load variables into a class?my variables look like this... (the whole point of playing around with variables was that if I had to make a change I could access one place and change them but now I realse that I can't access or call them outside the movie clip they are in.[code] The Wholesale price. A wholesaler is usually a big shed where goods are stored.
I'm trying to make a Class for a slideshow. I have a problem using the setInterval and clearInterval methods.See my code below. In the showPic function I have a conditional clearing the interval (repeating the showPic function). At least, it should do so, but it's not working. The interval continues. I'm using "this" so that's not the problem. Maybe it has to do with the scope of the variable to which I assigned the interval?
I finally got the variable referencing between classes and custom event problems sorted out. Now I got a question regarding the Error #2044 and Error #2035. The error reads like this:
Error #2044: Unhandled IOErrorEvent:. text=Error #2035: URL Not Found.
I've put all the swf in the same directory, so I don't think that is the problem. Could it be that my XML file is in another directory that's causing the problem? I also heard having quotes in the URL in the XML file could also be problematic. Is that true? Here are my AS and my XML file. [code]......
I've rarely used static variables or methods when creating external classes, but I have on occasion, and it's very useful when I need global access to a value. I've seen negative criticism on the use of the "static" keyword, but never understood why. Is there a right and wrong way of using it, or is this not true? I'd like to use it in a context similar to classes such as MouseEvent or TextFieldAutoSize, where there is a list of values globally accessible for identification purposes.
It allows better code readability, and also allows for easy customization in the future. The value of TextFieldAutoSize.NONE is "none", but as long as a programmer used the reference TextFieldAutoSize.NONE and not the string literal "none", Adobe could change the value of TextFieldAutoSize.NONE to be "hahahahaha" and everything would still work just dandy because (TextFieldAutoSize.NONE == TextFieldAutoSize.NONE) is still true even though ("none" == "hahahahaha") is not.
Is there any kind of negative impact on using static variables this way? Or even functions for that matter? I'd just like to clarify this before I go and build a large project around the idea this is perfectly okay.
i've got two classes and i'm not extending to MovieClip. I like to attach the mc in the constructor just because i'll be working with different MC's that have the same purpose.
however, im using private var loadedMC:Movieclip and now i've got another class that needs to be able to access the instance's variable.
for example, myClass.loadedMC , but this would mean having to make it public and I rather not go that route.
I just started using flashdevelop and I have some problems with importing all classes.
1. I used export all classes to SWC file and I added it to the library in FD. How can I import instances placed on the stage without creating AS linkages? I don't want to export these instances for AS, because some of them are textfields. By making linkages I'm forced to transform them to Sprite or MovieClip (am I right?) and my methods connected to these object don't work anymore.
2. When I export my project in FD, I get error 1065: variable Main is not defined. Main is my document class. I made this class my entry in FD.
I'm using flash CS4 and actionscript 2.0. I have a situation where I need to locate and check the date of an external file (either .exe or .swf) and return that date string to a variable in flash. I then need to display that date to a piece of dynamic text within the flash file. Is there a function within action script that will check and retrieve the file date of an external file.
I am trying to add a Paypal Buy-It-Now button to my Flash site.The basics are simple enough:
this.cmd = "_s-xclick";this.hosted_button_id = "1234567"; this.getURL( "https://www.paypal.com/cgi-bin/webscr", "_blank", "POST" ); ...however, one of the button parameters to post is called 'return'.
The examples I'll use don't do anything - they're classes without ANY members - no variables, methods, anything.
Let's say I extends Sprite and call it MySprite.
I save it in test.core
[code]...
Now I create another custom class called MyWindow that extends MySprite.
I save it in test.windows
[code]...
Then I create another class that extends MyWindows (the example I'll use is a document class - but that doesn't matter - I've tested using an instance too).
[code]...
Notice that I'm not even trying to instantiate the helper classes - just having them there throws the error.
If there is only a single helper class, everything runs fine.
Also note that - as far as I can tell - this only happens when extending one class from another package, then extending that class with more than one helper object.I'm pretty sure there's no namespace bumps or typographical errors, as this is a very pared-down version of the original application.
EDIT: seems the problem exists even without the crossing packages - even extending MySprite in the document class with multiple internal classes generates this error.
I am creating a library in AS3. Inside the library I make use of a bunch of classes/packages that need not be exposed to the end user of my lib. I want to only expose one of these classes.
I guess my questions are:
1) How are libraries commonly distributed in AS3?
2) Is there a .jar equivalent in AS3 that developers can include, but will only have access/knowledge of the classes I've declared as public?
I have an actionscript project which uses visual symbols from an SWC. I have a CheckoutButton which has the following class associated with it (compiled into the SWC in Flash CS3).
I'm having some troubles with the use of interface and inheritance in AS3. I've done lots of OOP in the past and what I'm trying to do seems obvious to me, but doesn't work in AS3. The question is : Is it possible to override a function that return an Object of class A, and make it return an Object of Class B which extends A ? It seems not to be possible, since I'm getting a signature error in Flash, when compiling. For example, the following set of class do not compile (the code in function definition doesn't matter):
