If i have a function and im strict typing: such as

obviously the second doesnt work because y is a movieclip and x is a number, but i want to be able to set x to whatever type is being passed in.
I'm trying to convert some C# code I have and one problem I can't find a solution for is to have a function take parameters of unknown types.
C# code:
PHP Code:
public T Maximum<T>(T v1, T v2){ return v1 > v2 != null ? v1 : v2;}
A straight translation to AS3 would look something like this, for making it easier to understand for people that might be confused by C# syntax.
[Code]...
This way you can send in anything as the parameters (notice the <T>), be different classes for example, depending on what situation you want to use it, instead of writing a lot of duplicate functions for every possible parameter type.
Is there a way to do this in AS3? Edit: Seems like I managed to find a solution right after I wrote this. Seems like one can use "*" as parameter type.
I've built a working video player which uses the following function to select and play one of 50 videos.
function playVideo(e:MouseEvent):void {

vidLink = "http//video1.flv";
ns.play(vidLink);

In my code there's a function that shows an image on the screen (or loads the image and shows a progress bar). This function is called by clicking on a thumbnail, and it uses a parameter [e.target.name] refering to the property "name" of the thumbnail clicked, which is an integer (or I believe so). The thumbnails are placed inside the cointaner_mc MovieClip.
Code:
container_mc.addEventListener(MouseEvent.CLICK, clickThumb);
function clickThumb(e:MouseEvent):void{
if (my_full_images[e.target.name] == undefined){[code]...
but I want to call this function by clicking on a button, which would need to pass another type of parameter, in this case, a variable which refers to the number of the image displayed on the screen plus one.I tried this:
Code:
clickThumb(image_num + 1);
But it doesn't work, I get the following error:
1067: Implicit coercion of a value of type Number to an unrelated type flash.events:MouseEvent.
How could I call the function clickThumb and make it use "image_num + 1" instead of "e.target.name" ?
Could I dispatch the event (MouseEvent.CLICK, clickThumb), passing this value "image_num + 1" ?
I'm trying to create a function that takes a Function as it's second parameter. I want to be able to give that function a default value as follows:
[Code]...
How should I declare the defaultUpdate function to avoid getting the following error?Code: 1047: Parameter initializer unknown or is not a compile-time constant.
if defining variable types in function parameters gives any speed boost.
e.g
ActionScript Code:
function DoIt(param1,param2,param3):void
{
[Code]....
is there any performance difference between above functions. in theory compiler should be able to manage memory more efficiently when knowing what data to expect, but is it so in flash
How can I define functions that can receive unknown/variable amount of parameters?

I've made an user login, working with php and MySQL. When the user logs in, he can see all of his details, loaded from a database. Here he can press a button to change this content. After changing it, he needs to press the "save" button to load the new data into the database. But everytime the user presses the save button, it's adding an extra line to the data into the database, which results in an error of displaying the data. Warning: Unknown: failed to open stream: No such file or directory in Unknown on line 0 Fatal error: Unknown: Failed opening required 'google_verify.php' (include_path='.:/usr/local/lib/php') in Unknown on line 0
View 1 RepliesConsider the following function:
Code:
public function foo(bar1:int, bar2:uint, bar3:String, bar4:Boolean):void{}
What I want is to have the different types of data represented by custom named types which are essentially representing the original data types. I other word, I would like to proxy the data types and have a valid function as following:
Code:
public function foo(bar1:PAR_Bar1, bar2:PAR_Bar2, bar3:PAR_Bar3, bar4:PAR_Bar4):void{}
so PAR_Bar1 would proxy the `int` data type, PAR_Bar2 would proxy the `uint` data type, so on and so forth.
The reason I need this is because I'm using a debugger with a GUI that can run methods and allows changing function parameter values in real-time, the issue is that the debugger can't tell me what parameter I'm changing, it only displays the data type of a parameter. So if I need to change 10 different parameters all of type int, the debuggers display all of them as int and not by their names.
I think that if I use proxy types I can easily differentiate between parameters.
So, my question: Is it possible to proxy data types? I mean map specific data types to custom data types that would represent the base data types?
Can we skip an optional parameter and assign value to the parameter after the skipped one?
For example I have a function:
public function Dialog(message:String,title:String="Note",dialogsize:int=99):void
{
}
I can easily call the function with a message and a title:
Dialog("HELLO","Intro");
Is there a way to skip the title and just pass in the dialogsize? I've tried it but can't make it work:
Dialog("HELLO",,dialogsize);
Is it possible to skip some optional parameters without using (rest) parameter?
I'm working on a game, and I need a bit of advice on functions, as well as something else. It's going to be, basically, a text adventure game, in flash. I need help with calling functions, like if you typed "look there", it would call the function "look" with the parameter "there". Is there a way to do this? I also need to be able to show the things you typed previously, like in a dos prompt. such as:
[code]...
with the ":" being where you type the next thing. Also, does anyone know how to show that little ":" before each thing you type?
I am trying to read a XML file and check a parameter for duplicates of that parameter in the file. There could be up to 200 entries with this parameter which is a number. How can I check to see if there are any duplicates?
View 2 RepliesForgive me for this stupid noob question but I want to call a function (loadList) that originally gets triggered after a mouseevent from another function (addToXML) that does not have an event.
The loadList function takes info from a XML var, sticks it into an array which then gets loaded into a tile list and that is working fine.
The addToXML function when called adds elements to the XML var after which I want to call the first function with the event parameter so it refreshes the items in the tile list.
I know it can do this by creating a new array and loading that into the tile list in the addToXML function, but it be much simpler to just recall the function.
I have tried things like
Code:
addToXML.addEventListener(Event.COMPLETE, loadList);
but all the event constants I have tried give me error messges like "1061: Call to a possibly undefined method addEventListener through a reference with static type Function."
I have a series of calculations i'm doing over a bunch of objects stored in a array. Each function is pretty CPU demanding but if you only run one function, it just works fine.

I've got a project thats getting a bit big, so Im taking the actionscript out into separate as files. I want all the basic functions to be in BasicFunctions.as and the make a library for more specific functions. I find that a lot of people use the import statement but I cant get that to work with a simple Hello World trace, yet the include statement works fine (see attached). I understand that import/include work differently, but which is the better method? If import, then is that heavier to work with. Any rate, what's the best way to organise code when it gets to the 1000+ lines?

I'm trying to find a way to have global functions in my as project, similar to how flash does with stuff like the util functions (describeType()...), where you can just call the function wherever you need it. For example:
[Code]...
So when I call Test(), it prints out "hello world" fine. My problem comes in that I can't change the name of the Test function, and I can't add any other functions without compiler errors. Is it possible to have a load of global functions in one file, or do I have to split them up into separate files like in the example? Also, I know that I can make a Global class and call static functions like Code: Global.doSomething() but I'd like to know if there's a way to do it as flash does it (describeType(), getDefinitionByName(), etc), or rather, how does flash do it?
Is it not possible to call other functions from generic mouse event functions?

I have one function that puts text in a text field and makes a button goto a url onRelease.The code is like this:
Code:
item.onRelease = function() {
myButton.onRelease = function() {
getURL("http://google.com", "_blank");
}
talk = this.txt;
}
the only problem is that the button doesn't work onRelease. i think that it is because there are too many functions there, but at the same time,
in this example why the values of (12) and (21,39) are lost at the geo and geo1 functions

View 1 RepliesIm adding lot of simple functions to prototypes of top level objects ( Object , Array , String ...) and have 2 questions :
Is possible to add functions to top level's classes in compile-time ?
If not , is there a way to allow this functions to compile ? I dont like to turn off strict mode
ex:
string.removeWhiteSpace();
string.sliceStr("." , "end");
textField.scrollBottom();
this return compile-time error , cause there is no such function , i have to write it in braces :
string["removeWhiteSpace"]();
string["sliceStr"]("." , "end");
textField["scrollBottom"]();
and i like to aviod it )

Right now I have a fixed number of items so I can just write the code below.How could I set this up to work so that it could deal with any number of items in the arrays.The length of all the arrays will always be the same.It could even be one array I think, as items could be fed in in order.[code]
