ActionScript 3.0 :: Reference To A Function Without Knowing Its Name Until Run-time?
Sep 22, 2010
I was just wondering if it was possible to get a reference to a function without knowing its name until runtime, in a similar way as getattr() can be used in python?
One can easily remove a listener like so: circle.removeEventListener(MouseEvent.CLICK, maskSquare); BUT, is it possible to remove a listener (or preferable ALL listeners) from an object WITHOUT knowing the function that the event is tied to?[code]
I have this clock code and would like to know what needs to be added or changed for it to reference the time off the server and not the local computer time (and preferably reference the server just once and not repeatedly). I already have a file on the server "time.php" that is providing the milliseconds. I know it should be fairly simple, but I just can't wrap my head around it.
My goal is to change the time for setInterval each time the function is called. Planning to replace myInterval = 5000; with a randomized number. My problem is getting setInterval to recognize the myInterval variable from the function.
I have an AS3 program that calls a function multiple times. The function must return multiple variables, so I created a class for the function to declare an object containing all of these variables. For example, here's my class:
package { public class PER { [Code].....
Let's say the calling program calls the function, which returns the variables into data_set1 (where data_set1 depends on input variables arg1, arg2, arg3) using:
var data_set1:PER = function_name(arg1, arg2, arg3);
The calling program does some stuff, then calls the function again, but returns the variables into a new variable name, data_set2:
var data_set2:PER = function_name(arg4, arg5, arg6);
My intention is that data_set1 and data_set2 are different (e.g. not linked together).
My question is, given that arrays are passed by reference, will data_set1 be modified to agree with data_set2 upon the 2nd function call? Why or why not?
i have a function that read a variable from a text file, yet i can only read the variable from within the function. How could i create a global variable or such that i can then read from outside of the function.
Code: var Make:LoadVars = new LoadVars(); Make.onLoad = function() { VARIABLE = Make.textVariable;
I thought I understood this stuff by now; the objects within a function are onlyaccessible within that same function, unless you return it to whatever called the function.However I dont think that you can do that for a function called with an eventlistner, so I set up what I thought was a global variable and set its contents within the function, thinking that the contents would be accessible later:
ActionScript Code: var bmpd:BitmapData; var URLReq:URLRequest = new URLRequest("sample.jpg");
Got a list of MCs being populated from an XML file. Basically a list of two different types of information. Some are type A, some are type B.
Want to have a couple buttons that filter based on type (so if I push the button for type A (called "typeAbtn" below), only those MCs appear and type B MCs go to _alpha = 0 or something).
Can't seem to come up with a function to do it. I can't figure out how to reference all my MCs from outside the first function correctly.
terrible attempt:
Code: function showMCs() { for (var j = 0; j<stuff.length; j++) { MC = timeline_mc["MC"+j];
I am using a delegate sub-class to perform helper functions for the main app.I have passed all references to it that it needs and it works well apart from the following problem:I also want it to remove an event listener from the main pp.eg:thisStage.removeEventListener(MouseEvent.MOUSE_UP,preOutsideBoundsDragRelease);The compiler tells me I need a reference to "preOutsideBoundsDragRelease" within the removeEventListener statement.eg: "access of undefined property preOutsideBoundsDragRelease
I have a dynamic input textfield and I have a scrollbar successfully scrolling the text. As soon as the textfield receives focus the scrollbar tweens into position. I would like to have the scrollbar tween in only when it is needed, which of course would be when the texfield has one more character than it can display in the viewable area. Is there some sort of event I should be listening for that would tell me that the textfield has grown past the viewable area?
Is it possible to know the dimensions of an flv loaded throught an URL ?
What if you want to load different videos with different sizes on the same video object? Does the video object change in size depending on the flv you're loading?
i want to pass by reference so i can use this variable outside the function.
What im doing is creating a global variable such as var cont:int; and then in a eventListener like enter_frame (stage.addEventListener..) calling a function called "mover", this function modifies "cont" value and i just want to print this value modified. The issue is i cant pass the value by reference just by const :S. The function is void, but if i change it to return int, its useless because each time i call the function, the value i want to return its created each time with a new value, beacuse i need to declare it so.. I read i can use a var such as Object but i really dont get it (im used to c++ i have to say)
I am trying to run a function of the main class, but even with casting it does not work. I get this error
TypeError: Error #1009: Cannot access a property or method of a null object reference. at rpflash.communication::RPXMLReader/updateplaylist() at rpflash.communication::RPXMLReader/dataHandler()
I'm attempting to write a performance testing function that can take any function, run it X times and spit out how long it took that function to run in AS3. I've got it working just fine if a function doesn't take any parameters but it comes up with an error otherwise.Here's the code:
public static function testFunction(targetFunction : Function, object : Object, ... parameters) {
In AS2 I have several arrays constructed like this : var myArray0:Array=new Array(value,value,value...) var myArray1:Array=new Array(value,value,value...) var myArray2:Array=new Array(value,value,value...) var myArray4:Array=new Array(value,value,value...) ...
What I'm trying to do is use iteration to reference each array name to pass it into a function. Like : function doSomethingWithArray(arrayToPass){ ... } //Later somewhere in For loop... : _root["myButton"+i].onRelease=function(){ doSomethingWithArray(WHAT-THE-HELL-I-TYPE-HERE[i]) }
Say I have a class B that extends class A.In class A, I have a variable that I've declared to be a function, which gets defined in the constructor. Now, in class B, is there any way to reference that function with the use of super.functionName()?
I'm making a function to be called by different buttons, and I want the function also alter the appearance of the button itself. But I don't know how to refer to the button from within the generic function.
How would one get a reference of String global function (not class). According to language reference this function does exist (and I'm ready to believe it does), but, say and you have a:
First shortly about how my site works: When a link is clicked it checks if something is already displayed in either the Left or Right side of the screen (the website looks like a book, so I have a left page I want to display information on and a right page). If there is already something showing it hides it and displays the new object, together with this it enables all the buttons within that object (I have separate functions to set up each object).
What I'm trying to do is to remove all the previous set EventListeners without having to create separate functions for removing the links inside every object as well.
How do I remove all EventListeners on all objects inside another object? The only variable I want to store is the object containing everything. There are however not always EventListeners within the objects.
I have a few functions that accept several parameters. [code]...
Is there a way to loop through all the params (without knowing how many or their names) and put them in some kind of an array with their names, so I'd get an associative array [code]...
I'm trying to use the BitmapData.draw() method on a sprite which I create through my own external class, but all I was getting was white. Finally figured out that it was taking a half a second or so for the sprite to pop up on the stage, and the draw method was apparently "pixelizing" it before it was drawn.
So my question is, how does one know when a non-loaded object is "ready"? Do I need to add my own event sent from the end of the external constructor code? I don't want to modify the class just to snap a picture of it. Waiting an arbitrary amount of time with a timer seems wasteful too.
Code: Select allvar bc:BarChart = new BarChart(500, 300); addChild(bc);} var bitmapData:BitmapData = new BitmapData(500, 300);
