ActionScript 2.0 :: Anonymous Function Return Values?
Aug 23, 2007
little bit what Im trying to do: I have 2 SWF, one.swf and two.swf 1 LocalConnection to send 1 variable from one.swf to two.swf
one.swf code:
var param:Number = new Number(5);
var sending_lc:LocalConnection = new LocalConnection();
sending_lc.send("_Connection1", "myMethod", param);
[code]...
I need to be able to use param value out of the function, because a I need to perform a switch with this value, since the function wich receives de param value is an anonymous function I dont know how to do to get the value from outside the function because a dont have a reference name to the function so, the normal way to return a value is not going to do the job.
Getter functions allow obj.meth syntax instead of obj.meth(), I'd like to create an anonymous one of these to return from another function. function get ():Object { } is invalid syntax. I don't suppose Flex offers an easy way to get this functionality, if it's even possible?
I'm pulling info from an XML file... there are three variables (year, month, day) that I need to process further in another function, but I can't figure out how to send them out of the function and into the next for processing.
Is it possible to make their values globally accessible?[code]...
Im calling a function in lua from actionscript using callstack : Array =
luaAlchemyInstance.doString("luafunction");
my function should return some values
function luafunction() return true, 125 end
When i look at the callstack array returned by the function in as3,I recieve only the success/fail part.The array length is 1, true, and contains none of my return values.
I'm trying to make a login function that receives the username and password as arguments, does all the proper URLRequest and URLLoader stuff inside it, and retrieves some values from the database. Then, it puts those values inside an object (a little associative array really) and returns them. I've put 'trace' sentences all over the function, and it seems to be working without a problem and is retrieving the right values from the database. However, when I try to assign the returned value with something like:
I have an event listener with an anonymous function literal, rather than a function reference. What I am trying to figure out is how to remove that event listener.Obviously, I need a reference to the anonymous function, so the two functions are ===. But, something is going wrong... it just doesn't work, ad this situation doesn't generate any feedback to tell me what might be wrong.There is some good info here, but not a clear explanation.
Code: private static var _myFunc:Function; public static function addCreditsToolTip(clip:DisplayObject):void
In as3, I am adding event listener and then attaching the anonymous function to it:[code]Now this whole piece of code is looped n times. Now, I have n myBoxes and whenever I roll my mouse over the box, it should alert the name. But, what I see is that the last value of count is used by each box. How can I pass parameter or value to the anonymous function? ( as roll over , I believe, expects only one variable)
I am trying to play an MP3 File in Flash Lite 2.1 (I'm using Flash 8 to develop it). The filename of the MP3 file is imported from an XML file.Here is a copy and paste from the help file on how to do this:
// create a new Sound object var my_sound:Sound = new Sound(); // If the sound loads, play it; if not, trace failure loading. my_sound.onLoad = function(success:Boolean) {
[code]....
When I test this code on its own, it does work fine for me. However, I want the above to be executed inside a function that does a number of other things... Here is a sample of what I'm trying to get working.
function myMusic() { // create a new Sound object var my_sound:Sound = new Sound(); // If the sound loads, play it; if not, trace failure loading.
[code]....
I think it's got to do with the fact that once I put it inside a function you are nesting functions (there is a function call from the onLoad event).
I tried changed the line:
my_sound.onLoad=function(success: Boolean) { to my_sound.onLoad=myFunctionName(parameters go here)
and then I created a funciton called myFunctionName but I wasn't sure how to send the sound object or what parameters the function should have or how to get the .start() method to work inside the new function.
up.addEventListener(MouseEvent.CLICK, function clickFunc(event:MouseEvent):void { revealSpinner(event,51.42,1,spinner);
[Code].....
The above code adds a listener to a couple of MC's. Originally the methods were anonymous but I have named them clickFunc() in order to try an reference them in my remove listener.
Here is my remove listener code. Both of these snippets are in separate functions. The add listener method is called before the remove method.
If I want to send an object to a function with one child called foo equals "bar", i need to do the following:[code]is there a way to declare the object in the function itself ? something like that:[code]
I'm trying to differentiate anonymous functions like:
function() { trace("WOO"); }
from the other ones ('named'?) like
var _FUNC:Dynamic = function() { trace("WOO"); }
The reason I want to do that is because I can't compare between two anonymous functions, because they are two different ones.
var _TEST:Dynamic = function(a:Dynamic):String { var _TESTA:Dynamic = function() { trace("WOO"); }; var _TESTB:Dynamic = _FUNC; return (a == _TESTA) + ", " + (a == _TESTB); }
If I run _TEST(_FUNC);, I'll get back "false, true". Even though they are the same function, they are NOT the same object.Is there a way to compare those such that functions that they are the same if they perform the same task? Is there a way to serialize functions? So that maybe I can compare the serialized representations and see if they share the same 'code'.
In c++ if I have a function that takes a class I have defined elsewhere as a parameter like so:void moveto(CPoint2D point) { ... }I can invoke it and pass along data to it like this:moveto(CPoint2D(0,0));basically creating the object and invoking it's constructor to be passed to the functionIs there an equivalent to this in AS3?if I have a function like this:function initialize(min:Point, max:Point): void { ... }how do I do something along the lines of :initialize(Point(0,0), Point(10,10))This throws an error im assuming because it thinks I want to cast something to a point and the notation I found earlier to do something similar only seemed to work if using the basic Object class.
I'm new to AS3, and can't figure out why this loop isn't behaving the way it "should."
[Code]...
How can I give each anonymous function a reference to each object represented by f, rather than a simple reference to f each time? Specifically, why is it that each copy of the anonymous function gets bound to a single reference to f? How (I should say why) exactly does AS3 differ from JavaScript in this regard?
I have a button labeled 'blueButton' and I'd like to use an anonymous function to handle the click, like so:
blueButton.addEventListener(MouseEvent.CLICK, function(event:MouseEvent):void { trace( "-----click detected-----" ); // now do other stuff });
Problem is, the click handler is called multiple times per click. The number of times called seems to be random (sometimes 2, sometimes 4, sometimes 3 etc). could I be missing something in my code, or maybe I set up the button wrong?
also I noticed that it seems to always get called once on the first click. After the first click is when it starts getting called additional times, maybe that has something to do with it?
I want to know why my update doesn't populate local Sqlite database. Yesterday with few records in database application worked correctly. Today after inserting another 10 records. Both send method seem to work properly but they don't return data. It updates only IngredientDB but not RecipeID Request . This is my update action script code,[code]
i am realy new to flash.i want 2 get the position of the mouse click and move an object 2 it.i want to know is it possible to return mc.mouseX and mc.mouseY from this function.can u tell me what r the modification for this code.[code]
I need to get a javascript var in my Flash application. I like to be able to just set a variable in the javascript (client constraints) rather than define a function.
Can this be done? I am trying to use the ExternalInterface.call()
I'm developing using Actionscript 3.0 for Flash Player 10.3.I'm using computeSpectrum() on a loaded .mp3. Running *Event.ENTER_FRAME* to get snapshots of each sample in an byteArray.The ByteArray contains 512 values (256 for each channel). These values are FFT Spectrum, ranging from 0 to 1.I can't use the peak frequency for each of the samples (as I found found out!) because the highest value is not necessarily the fundamental frequency. As a result I'm getting lots of random values all over the place.Of course I'm getting some correct too, but that's not enough.
create a random subtraction equation where the result will always be positive? For example, my current scripting will return something lilke 3-6=-3. I don't want equations like this- only postive answers
//random numbers//1.function randomNumbers(min:Number,max:Number) var Results:Number=Math.floor(Math.random()*max)+min; return Results;} //2.new_mc.addEventListener(MouseEvent.CLICK, showRandomnumber);
have this code that's supposed to return the an array that holds the values that were contained within an XML node.

for some reason, the code won't return anything. the output just says "undefined". Would a good workaround consist of putting the return function within a setInterval method?
I trying to populate a combobox from a .php file and return the values of the selection. I have the .php set up to where it outputs something like
&artists=anartist,anartist2,anartist3, etc..they have names..I already have the combobox set up to where it displays
anartist anartist2 anartist3
after you click the dropdown arrow..How would I get it to return a the numerical value for the artist (ex: anartist would be "0" since it is first in the list) and put it into a variable so that when it is selected it could be placed into an eval() function to create a variable such as "albumcover0" to be loaded through a function. I have been reading tutorials for hours to no avail.I want a single function to produce the number from the selected artist and place it into a variable, then go through all of the loadImage(for the "album image") etc functions..they will be functions that I have made already previously and call all of them with the number in the called fuctions (ex: loadImage(0)) where "0" is the number derived from the variable out of the combo box.Ive tried tons of tutorials, I think that it has something to do with me using flash mx 2004, and as2 turned on.
I have just started using external AS3 files to try wean myself off using code in the main time line.I am importing an XML file using an external as3 file, but cant return the values to the main timelineIt worked when I used the trace option, but I need these values to dynamicly populate a movieclip on stage (another problem I cant add movie clip to stage even though I have the linkage etc)AS3 Code ----------------------------------
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):
I'm using an AMF service that was built by someone else. Basically what happens is that some info is passed to the AMF service and it returns true or false.I want to be able to pass in various info to the a function that calls the AMF service(submitTracking) and then get the true or false value returned in onResultSubmit to be passed back to submitTracking.
var screen:String; var buttonnumber:String; function submitTracking(screen:String, buttonnumber:String) {
Anyway, I have a function that goes through an XML file, looking for a specific value. If it finds it, it should return the node that contains that value. However, I'm having trouble with the whole return part of it.My code is:
I am trying to have the function toggleClick return powerData. I need to store powerData in a variable and have it passed to another function to do calculations.
Inside the function toggleClick, I am assigning powerData to houseArray[e.currentTarget.name.toLowerCase()];
var powerData:int = houseArray[e.currentTarget.name.toLowerCase()];
I tried just to write return powerData--but it breaks the program.
// function toggleClick function toggleClick(e:MouseEvent) { // Store "Power" Values of House Objects in Array
I'm communicating to these movie clips with another program via binary sockets.For the first set of movie clips: when it recieves its instance name, and a second number (InstanceName+#) from the socket, the named movie clip will jump to the frame corresponding with that number. for ex:if the incoming data from the socket is (mc7+3), then movieclip 7 will jump to frame 3.
For the second set of movie clips: when it recieves its instance name, and a second number (InstanceName+#) from the socket, the named movie clip will move location across the screen, by the y coordinate moving to the # given by the socket...thats a little confusing. for ex: if the incoming data from the socket is (mc4+500), then movieclip 4 will move so that it's y coordinate is at 500.[code]...
