Exchanging Data between FFishScript and FLEX..

[stevekellogg]

Hello,

I've read over all of the manual, but I need help with something.

I'm working in Flex 2.01. I'm trying to get access to variables defined in Flex using the "FlashPlayer.getVariable" and "FlashPlayer.setVariable" methods.

The PROBLEM is that I don't know how to correctly format the NAME of the variable that I want to get.

I've tried everything obvious I can think of :

FlashPlayer.getVariable("root.myVariableName");
FlashPlayer.getVariable("_root.myVariableName");
FlashPlayer.getVariable("myApplicationName.myVaria bleName");
FlashPlayer.getVariable("_myApplicationName.myVari ableName");

etc...

Can anyone here help me out?

Thanks in Advance.

Although you can use the getVariable method to get properties of the Application object (or any components in the Application container), such as _x, _y, _width, _height, it cannot return the value of a variable defined in the Application container. The name of the Application container is the name of your project plus 0. For example, if your project is "myTest", then the name of the Application container is "myTest0", and you can get its properties in ffish script like

var x = FlashPlayer.getVariable("_level0.myTest0._x");

To pass data between flex 2 and ffish script, you can use the ExternalInterface object to call as3 functions in ffish script or call ffish script functions in as3, both synchorously:

1. calling as3 function from within ffish script

i) in as 3 define and register a function

*********function myFunc(x, y)
*********{
************return x + y;
*********}
*********
*********function myMethod(x, y)
*********{
************return x + y + y;
*********}

************ExternalInterface.addCallback("myFunc", myFunc);
************ExternalInterface.addCallback("myFunc2", myMethod);

ii) calling the methods in ffish script

// The "registerASMethods" method turns any as2 or as3 
// callback functions into ffish script global functions. That is to say,
// you can call the action script functions directly in ffish script 
// after calling this method 
Application.registerASMethods("myFunc", "myFunc2");
trace(myFunc("hello ", "world"));
trace(myFunc2("hello ", "world"));

2. calling ffish scripts from within as3 synchorously
i) you can call it directly by using the ExternalInterface object

ExternalInterface.call("ffish_run", "myscript");

ii) first define a function, then call the function

function callFS(name)
{
    ExternalInterface.call("ffish_run", name);
}

callFS("myscript");

3. calling ffish script functions from within as3 synchorously
i) first define the function in ffish script ("initialize" script)

function fsMethod(x, y)
{
***return x + y;
}

ii) calling the ffish script function in as3 by using the ExternalInterface

ExternalInterface.call("fsMethod", 123, 56.0);

or first define the function in as3:

function _fsMethod(x, y)
{
    return ExternalInterface.call("fsMethod", x, y);
}
ret = _fsMethod("hello ", "world");

or use the "ffish_eval" command

ExternalInterface.call("ffish_eval", "fsMethod(123, 56.1);");

Thank you SOOOOOO Much.

That's what I needed!

Best Regards,

Steve

You can't.

i type in as1/as2

function myFunc(x, y) {return x + y; }
function myMethod(x, y) { return x + y + y; }
ExternalInterface.addCallback("myFunc", myFunc);
ExternalInterface.addCallback("myFunc2", myMethod);

and type

Application.registerASMethods("myFunc", "myFunc2");
trace(myFunc("hello ", "world"));
trace(myFunc2("hello ", "world"));

in initialize script.
It prints 'undefined'.
Where the problem can be ?

[SWFKit]

There are two problems in your code.

First, in the as2 code, the parameters for the "addCallback" method are incorrect. Your code works in as3, but in as2 the method has three parameters. Therefore in as2 your code should be

function myFunc(x, y) {   return x + y; }
function myMethod(x, y) { return x + y + y; }

ExternalInterface.addCallback("myFunc", null, myFunc);
ExternalInterface.addCallback("myFunc2", null, myMethod);

Second, in the ffish script code, you cannot call the as functions in the "initialize" script, because at that time (when the "intialize" script is running) the main movie has not been loaded yet, and of course the as functions are undefined. Hence, you can only call them after the as functions have been defined. The following code works well

Application.registerASMethods("myFunc", "myFunc2");

function testResult() {
trace(myFunc("hello ", "world"));
trace(myFunc2("hello ", "world"));
}

Application.onMovieLoaded = function (movie) {
testResult();
}

Hi,

I am struggling to make an application work.

I have to send some values to SWFKIT from SWF and do some calculations then retrieve the values back in SWF. SWF is created in AS3.

Any sample available for this?

Inside SWF

PHP Code:

var btn:Btn = new Btn();
btn.x = 100;
btn.y = 100;
addChild(btn);
btn.addEventListener(MouseEvent.CLICK, onClick);

function onClick(e:MouseEvent) {
    if(ExternalInterface.available) {
        ExternalInterface.addCallback("fsMethod", newMethod);
        ExternalInterface.call("fsMethod", 123, 56.0);
    }
}

function newMethod(val:Number) {
    ExternalInterface.call("showAlert", val);
} 


In SWFKIT

PHP Code:

function fsMethod(x, y)
{
Dialogs.msgBox(x + y);
return x + y;
} 


fsmethod is the method defined in swfkit and newMethod should be called from SWFKIT method after the calculation.


What should I put in SWFKIT?
