ActionScript 3.0 :: Calling A Function Sending Different Data Types As Parameter?
May 23, 2009
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 am sending a name of a function via parameters to another function. This allows more usage of a single function. However, the button commands work every-so-often. The message appears everytime with no problem.
Code: _root.msgReveal("This is just a random message. Click the ok button to close.", false, true, false, false, _level0.msgHide(), false);
Let's say I have a function that accepts a function and some arguments as parameters. Something like:
ActionScript Code: function myFunction(func:Function,args:Array):Void{ // do something awesome here };
How would I go about calling this function with the arguments in args? It's pretty simple to call a function without any arguments, but calling it with them..
As an example:
ActionScript Code: // I'd like this call myFunction(trace,["Hello world!"]);
I am using the asfunction to call a function and passing a parameter. The problem is in the parameter. I can give a parameter that is over 104 characters. What ever is after that 104th character doesnt pass into the string of the 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?
I am creating a gallery type site, I am loading xml data externally creating duplicate movie clips and it all works fine, my only problem is I want them to go to a URL, I have one of the nodes with the URL and in my actionscript I am calling a function to getURL on press, the problem is on each separate movieclip it links to the URL of the last movieclip in the stack.
Does anyone know of any really easy and effective ways to move complex data types from PHP into FLASH and vice-versa? A while back I made an attempt to recreate PHP' serialize() function in actionscript but it was really difficult and performance was poor.
I'm able to do it fairly easily for one dimensional arrays indexed by numbers, but when I have to pass either an object (or several objects) or when i have to pass a nested array of arbitrary complexity (such as a data tree) then I get bogged down.
I have a little experience dealing with XML in flash (working with the tree component) but it seems like so much effort when i am dealing with a new data type.
Does anyone know of any pre-packaged components or code (in actionscript and complimentary part in php) that might be useful?
public function foo(bar1:int, bar2:uint, bar3:String, bar4:Boolean):void{}

Im trying to wrap my head around data types and phrasing them from xml. From what I gather variables that come in from XML are always treated as a string - even if you declare them as something else before hand? Im not seeing that myself as everything else other then the Boolean is behaving as expected. For example in the code below, if I declare FGFILLCOLOR as anything other then an int, or Number, I get an unrelated type error. So why just Boolean and how can I convert them so they behave properly without declaring all of them as a String? Though I've seen a few related solutions posted around but I wan't able to sort them out.

WSDL defines a number of datatypes supported by web service . Is there a documentation stating the various equivalents of those datatypes on flex side. In general for any language that we use to consume web service, how do we get to know the equivalent datatypes of the wsdl types.
One of the web service that I am consuming is returning base64Binary (an image binary data) , What is the equivalent datatype of this on flex ?
In our application we have an embedded Flash control (in a HTML file in our Browser control) that shows some games. I looking for some way to call / notify this Flash control from C++ or JavaScript when some events are happening outside of it in order to display something / set it's internal values.
how (if possible) this could be acheived? I think there is an option to call JavaScript from C++ and then JavaScript call Flash, but that's looks a bit tricky to me. is there is a way to "call" the Flash control "directly" or send a message to it.
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?
Primitive Data Types (Boolean, int, Null, Number, String, uint, and void) are treated as "values" rather than Objects, so when you pass one of them into a function, instead of passing a reference, it basically clones the information, and creates a new instance. It does the same thing when when you use "primitive1 = primitive2", and instead of passing on a reference, clones it.I thought there might be a slim possibility Flash allows me to reference primitives if I treat them as objects instead of (in this case) ints.
I will be creating a program to use for data entry. I'll be studying zebras in kenya and I won't have the internet there as I'm recording the data. I'd like to be able to send the data I generate in flash to an external text file. I understand I need some sort of script to do that, but is this something I can run just on my machine? (I'll probably make the data into xml format).
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?
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 have an interactive Flash simulation that I have imported into SABA Publisher. I need for the Flash file to communicate with SABA, basically returning that the user has successfully completed the simulation. SABA is supposed to be able to receive data from Flash.
I'm now finding the great need for classes as my current project is getting quite gummed up with too much scripting in the main document. Becoming a real pain to find stuff with in my code.
So I started writing a class to takes an id passed to it from the main time line, accesses my mySql DB, pulls the related info and the processes it. What I can't seem to figure out, is how to pass a variable back to the main time line. The traces all work, so I know my class works. I've searched here and via google, but I must not be searching the right stuff because I get a lot of results with are usually very complicated questions that don't yield the answers I need.
so here we go. my main.fla (and question):
Code: import Name; var theUserName:String = "Joe"; var processName:Name = new Name(theUserName);
[Code]....
ps: what's it called when trying to call a method from the main time line? or passing a property back to the main? are there specific terms for these?
Forgive 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.
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."
Let's say I have a Custom Event Class, and it has several Event types stored in static Constant:
[Code]...
Is there an easy way to validate that the type passed to the Constructor is one of the Static Constants of the Class, without having to check it against each value?
I'm having some trouble passing parameters with a function that is itself being passed as a parameter.In my application code I'm instancing that class five times:they are buttons in a menu.In that class, I've got an onRelease handler that does a number of things when a button is released, one of which is to invoke a function that is defined in the application level of the code.My problem is that I don't know how to send the function parameters.In my StandardButton class I have:
class StandardButton extends MovieClip { /* define properties */[code]..........
The function is successfully being "sent" to the StandardButton class, but without any parameters.How can I send parameters to the class instance with the way I've got this architected.
I have an AS3 function that loads and audio file and then plays it. I have the pre-loader for the first audio file working - now I need to run the pre-load function before the 2nd audio file starts.
i'm trying to modify some code and can't figure out what the issue i'm having it. this is the(shortened) code:
public static function Lose():void { trace("OVER!"); Clock.stop();[code]...
this is the error i get: 1180: Call to a possibly undefined method OverIt.i just want to call a function from inside of the public static funtion.both function are inside this class:
Okay so I am reading through sens tutorial on OOP and updating my game that I am making. It is much easier to code this way (IMO) but still hitting snags.I am trying to get through this code:
