ActionScript 3.0 :: Call Functions Declared At Runtime?
Jan 29, 2010
In my application I declare a class variable as Function and set it during runtime as I instantiate the class. But how do I call this function? Looked in the manual but my brains are not working properly at the moment.
I have been at it for days now and don't know how to get this going. I have DocumentClass and I have a simple function which returns stage width. I now would like to call this function from othr class which exist within the same package as my DocumentClass. I am able to trace the stage width when I invoke stageWidth() function from the DocumentClassAs I to understand, if the function is public, and it is being accessed by a class that exist within the same package, I should be able to access the function withou any issues.nd If I declare the function as STATIC then it is global and can be accessed by classes from other packages what am I doing wrong,
Function that I have written: public function stageWidth() {
it's just some little white 'snowflakes' that fall from the upper end of the screen)
ActionScript Code: var timer:Timer = new Timer(30); timer.start(); timer.addEventListener(TimerEvent.TIMER, onTimer);
[Code]....
Now, this of course gives a run time error (access of undefined property snowSpeedX) due to the fact that snowSpeedX is declared in the function onTimer. The reason it is declared their is because i want it to change everytime and so each snowflake that falls, moves in the x axis with a different speed. If i declared the snowSpeedX variable outside of the onTimer function, i wouldnt get a different value for every snowflake, i would just get one.
So, how do i get the snow flakes to have a varying range of speeds?
Can I call a variable declared in a SWF, and call the same variable into another SWF, when i am loading it using XML.I am declaring a variable in the "Child movie", and am loading this "Child movie" into a "Parent movie" using XML. Can I retrieve the variable declared in the "Child movie" in the "Parent movie".

I created a menu in flash and As3, nested in a HTML page, which calls html pages by the classic way urlrequest->navigatetourl.Now I was wondering if i can make As3 call a AJAX function declared in the HTML page or at least in the swf file itself....
I am dynamically creating movie clips using something similar to[code]...
This works fine for creating and loading movie clips, but at the same time I'd like to apply functions to these clips as they're created. For example, I'd like to apply a distinctive onMouseDown or onRollOver behavior to each ie ...
What I am trying to do is kind of odd, but I am wondering if anyone can come up with a clever way to do what I want to do. Basically, I want to re-define a named function at runtime. I can do this with anonymous functions, but I can't figure out a way to do it for named functions. I want to do this so that I can implement a "spy" functionality on an object for a testing framework (a port of Jasmine to Flex).
Take, for instance, this class:
public class TestClass { public var anonymous:Function = function():void { trace("original anonymous");
[Code].....
Can anyone more clever than I come up with a way to hack this? Can the bytecode be hijacked? Something?
I am writing some code that needs to be very efficient, yet flexible. This is in a class and when the class gets initialized a function is setup. I want this function to run straight through without doing any time-consuming things such as calling other functions or routines, or doing any if/else logic/branching. Now I know that you can setup a function at anytime during runtime such as:
Code: var myFunction:Function = function() {trace('HELLO!')}
But what I am trying to do is to try and append code to a function based on logic, yet I don't want the function to be deciding this logic when it is running as it will only need deciding when the function is created.... imagine if it were a string it would be something like myFunction+="do somethingelse;" which would be the same as having initially setup myFunction as such:
Code: var myFunction = function() {do something; do somethingelse;}
With this I seem to be having no luck Here's an example where I setup the most compact/efficient function at runtime depending on what I want the function to do. Now this was fairly simple because when we create the function there are only a few possible variations, but I need someway of doing a function+= as my real code has quite a few variations and it would be a nightmare have a zillion if/else branches. REMEMBER I do not want any logic/decisions in the function itself as it to be the most efficient the function must be as compact as possible and run straight-through.
Code: var dynamicFunction:Function; // // Setup the dynamic function & call it // In this example outputs "Hello Jim" & "Goodbye Jim" dynamicFunction = CrapSetupRoutine(true, true, "Jim");
[code]....
P.S. I knew the += would never work as this is a function and not a string. But at least if you think of the function as a string you'll get what I'm trying to do....
I'm trying to build an API in JS that will perform some operations and then execute the callback that's registered in AS when it's done. Because it's an API, I am just providing a JS method signature for another developer to call in Flash. Thus, the callback name that's registered in the AS part of the code should be a parameter that's passed in to the JS API in order for JS to communicate back to Flash.
For example: [AS3 code] ExternalInterface.addCallback("flashCallbackName", processRequest); ExternalInterface.call("namespace.jsFnToCall", flashCallbackName); function processRequest(data:String):void { //do stuff [Code] .....
Because the definition of the function is in AS, I can't use the window [function name] approach. The only way I can think of is to build the callback in a string and then use the eval() to execute it.
I am trying to figure out how to call a function in one swf from another swf both of which are loaded into the same master swf.This is my function in workPhoto.swf which is loaded into level 5 of the master.swf:
Code: function killThumbs() { image_mcl.unloadClip(thumbnail_mc);
I am trying to call a C++ function from actionScript3. using Programming ActionScript 3.0 > Using the external API > Using the ExternalInterface class > Calling external code from ActionScript, I could call function from JavaScript .
it will be good if i could call C++ functions directly from Action Script.
I am using ExtrernalInterface.call(javascript_function, args); to call javascript functions from Flex. But this fails in case of browsers that have javascript disabled. Is there any other way to call javascript functions from flex?
I have written two arrays for two separate functions and trying to have a button call both. How is this done properly? The function calls, collection() and left() are conflicting.[code]...
What Im trying to do is to call a function called e.g start(); from a class that extends sound. Iwe been trying for hours now. How can I make this work?
is there a way to call on my functions for one button..for example my home btn on CLICK event does 5 different functions. Is there a way to put those functions in some sort of an array and just call on that...
I have placed a movie clip on the stage, with the variable name mcThumbnail. The following code in entered in the first frame (the only frame of the timeline..).[code]...
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
Im doing something wrong.I have written two arrays for two separate functions and trying to have a button call both. How is this done properly? The function calls, collection() and left() are conflicting.Currently left() isnt working, but with collection() commented out it does.
I am playing with a page viewer which imports SWFs for pages from an XML file.If i make a button on one of these pages, can i get it to call the parent master SWF functions?I have tried this...
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.
