setVariable not working

[sbick]

I'm having a problem with setVariable modifying the variable in Flash......

============================
In the skp file I have:

//Initialize
function showDialogBox (vMsg)
{
Dialogs.msgBox(vMsg,'Value', 16);
}
function changeValue() {
FlashPlayer.setVariable("_root.test","value changed");
}
return true;
============================
In the swf file I have:

fscommand("ffish_eval", "showDialogBox('"+ _root.test+"')");
_root.test = "orgValue";
fscommand("ffish_eval", "showDialogBox('"+ _root.test+"')");
fscommand("ffish_eval", "changeValue()");
fscommand("ffish_eval", "showDialogBox('"+_root.test+"')");
stop();
============================
The output from the dialog box is:
blank
orgValue
orgValue
============================

The third value in the popup should be "value changed", right?

Please help!

Thanks,

Steve

Hi, Steve

You can treat the fscommands as messages which are sent from within Action script to the FFish script. The Action script engine just sends them without waiting for the return of the fscommands. That is to say, the action script engine doesn't care if the fscommands have been really executed.

In fact, the FFish script engine has no chance to execute the fscommands while the Action Script engine is still working. The fscommands

fscommand("ffish_eval", "showDialogBox('"+ _root.test+"')");
fscommand("ffish_eval", "changeValue()");
fscommand("ffish_eval", "showDialogBox('"+_root.test+"')");

are queued to be executed later by the FFish script engine.

Now as you can see, the value of "_root.test" is passed to the last fscommand

fscommand("ffish_eval", "showDialogBox('"+_root.test+"')");

But the second fscommand
fscommand("ffish_eval", "changeValue()");
isn't executed by the FFish Script engine yet.

So you cannot get the result as you want.

You can change the third fscommand to

fscommand("ffish_eval", "showDialogBox(FlashPlayer.getVariable('_root.test'))");

If you want to wait for the change of the _root.test, a callback function or frame would be helpful.

E.g. In ffish script

function changeValue() {
 FlashPlayer.setVariable("_root.test","value changed");
 FlashPlayer.targetCallLabel("_root", "a frame that would be called after the change of the _root.test");
}
