ActionScript 3.0 :: Create Different Variable Types From Single Function?
Jul 26, 2010
This is hard to describe in a sentence, so i'll write some false code: (with incorrect syntax, of course)[code]...
Is it possible to do something like this, where I pass the name of the data Type that I want it to create and it does it within the function? And I know that with this simple example it isn't necessary to do it this way, but in the full program this would save some time and make the code more efficient.

I'm trying to write a robust "eventMaker" function that I can run with arguments that will then create an event listener based on the arguments.
However, I can't seem to get it to pass the arguments. Functions are impossible to pass; it can't convert string versions back to functions, and passing the function as type :function just yields "function() function{}".
The same is true with strings and class definitions - if I want it to refer to an object in my other .AS file called "helloWorld", I can't make it think of helloWorld as anything other than a string or an object, and when I write commands based on it I get errors.
So how do I contain classes, functions, et al in variables that I can then reference again, in code, as those functions/classes? How can I convert a string value to something that the code will know is a reference?

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

Is it possible to create variables with a function? I don't mean create my own variable in a function but actually have the function create a unique variable name (eg. exam1, exam2 and so on) they would all have the same data type.

I have created a function that creates a pop-up text box: I have named instanceName as a String but sadly it doesn't work. The only way I can get it to work is to name the instance within the function. Is there any way of creating a variable for the instance name? [code]...

Im working on a chess game replay system in flash, and in order to display comments on individual moves I am loading them from an external text file. Since one of the navigation buttons allows the game to skip to the last move I want to also recieve the number of the last move through this text file. After using loadvars all the comments are loaded correctly as strings but the variable for lastmove is not being recieved as a number. My ultimate question is whether there is a way to convert the text number into a real number which can be manipulated. If not, is there a simple way to load this data element individually as a number.

I have a primary function that calls upon other functions, which call upon other functions, etc, each one creating different objects. I need to delete everything eventually and was thinking the easiest way to do this would be to have a global array to push() each object into. It would be easy to just put garbageArray.push(thisCreatedObject); into the for() loops of every function to grab all the objects so a deleteFunction() could just cycle through garbageArray to remove and null everything cleanly.
What I want to do:I could easily just create a global array to do this (code example 1), but I would prefer to be able to recreate this global array and delete it every time this primary function is called (code example 3) since it will be called upon a lot. It would be cleaner code to have it created from within the function as opposed to outside of it because I will have a lot of primary functions doing similar things that would require a global array like this.
I also know I could create one and simply pass it as an argument to every function (code example 2), but I would have to pass it to every single function. There are a lot of functions and a lot of calls to them, so this would require rewriting a lot of code and would be more work than it's worth. Making a global array outside of the function would be easier than doing this if it came down to it.
ActionScript Code:
//example 1 of global array. No passing as argument from
//primary to secondary functions. Multiple global arrays
//required for multiple primary functions in the future.

I'm wondering how I can create a reference to a function/variable by using strings. Sorry if I'm not explaining the problem well, but let me show you what I mean in an example:You can create a reference to a class using strings by using the getDefinitionByName as follows:var classRef:Class = getDefinitionByName("myClass") as Class;var myClass1:classRef = new classRef();Similarly, how do you refer to functions and variables? The reason why I want to know is because I'm trying to implement a function which takes in the event handler name as the parameter, and what the function essentially does is that it adds an event listener with the associated handler (based on the parameter) to an object, something like this:
public function addListener(handler:String):void {
mc.addEventListener(Event.ENTER_FRAME, "on" + handler);
}

I was just wondering if there are any problems that could arise from passing MouseEvents of different types (i.e. MouseEvent.CLICK or MouseEvent.MOUSE_DOWN) at different times to the same function? I've already built my project, and it seems to function fine, I just want to make sure that I'm not setting myself up for some problems in the future. I understand it's probably not the "cleanest" or "best practice" to construct my project in this manner, but if it works...
A simplified example:
PHP Code:
// This is the function that I want to call from varying places with different MouseEvents and triggered by different event listeners
function myFunctionA(evt:MouseEvent):void{
[Code] .....
Actually, in writing that, I may have answered my own question, because it seems that myFunctionA is simply expecting a MouseEvent... regardless if that event is CLICK or MOUSE_DOWN or MOUSE_UP event, right? Now, a MouseEvent.CLICK may have different properties than a MouseEvent.MOUSE_UP that I can access within myFunctionA; however, that shouldn't matter to the function, or is my thinking flawed?

Consider 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?

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 custom function called "turnOn" with (name) as the function variable(?is that how I should refer to it?). This function is an if/else statement that will be called through an on(release) button event.
The if has a bunch of && conditions, if true gotoAndStop on frame two of specified movie clip. But I'm trying to write it put it in a function so that I don't have to put all this code on every single button. So i'm using the "name" function variable to specify the movieclip that should be affected by button action, but it won't work.[code]...

how to set variable time for a single timer, like I first setup this timer:
private function timer():void{
var randomTimer:Timer=new Timer(time,0);
randomTimer.addEventListener("timer", somefunction);
[Code].....
So how can I influence the time inside the timer? Do I create a global timer, remove the listener and recall the timer function? Would this work since the timer has already been declared, I a re-declare a timer?

f you know PHP...then you know that you can create a string variable...and then use the value of that variable to declare another variable. like this:
PHP Code:
<?php$foo = "haha";$i{$foo} = "success";print $i{haha};?>
and it would display "success"...or like this:
PHP Code:
<?php$foo = "haha";$$foo = "success";print $haha;?>
and it would also display "success".

Is there a way to group a bunch of movie clip instances into a single variable? Reason is, I have a lot of movie clips acting as buttons that I have added to event listeners. All of the movie clips with do the same functions and I have a few different functions created.
For example. How can I change this
Code:
mc_aitkin.addEventListener(Event.CHANGE, changeAlpha);
mc_anoka.addEventListener(Event.COMPLETE, changeAlpha);
mc_aitkin.addEventListener(MouseEvent.MOUSE_OVER,hoverOver);
mc_anoka.addEventListener(MouseEvent.MOUSE_OVER,hoverOver);

I just want to create a scrollbar for some text, but instead of the up and down arrows im trying to create a single dragable bar. This actualy looked kinda simple, but now i just cant seem to get this right... I know i have to move the text up or down the same percentage i move the bar up or down, and the drag motion is combining mouse_down and mouse_move, the thing i cant seem to get right is the "how much up or down" part. Im trying to simply drag the bar up and down, without worrying about the text, but i just cant make it follow the mouse when i drag cause i cant find a way to tell that the mouse has gone "x" up or "x" down...

My movie is basically complete and consists of simple movie clips as buttons, these listen out for specific states and when these conditions are met a function is run which generally either plays a movie clip or runs a prevFrame loop.For some reason, although the mouse over and out conditions are working correctly the mouse down condition causes the variable to flip through 3 states which causes the panel im trying to show to basically run through 5 frames and then reverse for a single frame.I'm literally banging my head on my desk for a solution and my manager is starting to look at me a bit funny. Has anyone experienced anything like this before? Heres me code
