how to use flashvars in as3

[atnok]

hi,

I searched livedocs and many forums about actionscript 3. In as3 it was really easy to receive parameters from the embed code. i only used the _root-variables to get the parameters i needed. in as3 its not that simple. I made a actionscript-project in Flex with only one class:

package {
public var userid:String;
public class testClass extends MovieClip()
{
public function testClass()
{
// in as2 i got the userid like that
userid = _root.userid;
// in as3???


}
}
}

can anyone help me with that simple question?

See if this helps: ActionScript 2 Migration (http://livedocs.macromedia.com/flex/2/langref/migration.html)
Here's what they say in there about _root:
AS2.0 AS3.0 equivalent Comment
===== ======================== =====================
_root flash.display.DisplayObject.stage Removed. The closest
equivalent is the Stage,
which serves as the root
of the ActionScript 3.0
display list.


Hope that helps,

Well that editing job pretty much sucked huh?
Let me try it another way.
ActionScript 2.0: _root
ActionScript 3.0 equivalent: flash.display.DisplayObject.stage (http://livedocs.macromedia.com/flex/2/langref/flash/display/DisplayObject.html#stage)
Comments: Removed. The closest equivalent is the Stage, which serves as the root of the ActionScript 3.0 display list.

Phew! There, that's a lot prettier looking LOL

hi,

thanks. i tried that. the problem is that stage is a DisplayObject.

i tried:

userid = stage.userid;

userid = root.userid;

userid = stage.root.userid;

i always get that error:

1119: Access of possibly undefined property userid through a reference with static type flash.display:DisplayObject.

i discovered the problem: like this it works fine:

AS3:
package {
public var userid:String;
public class testClass extends MovieClip()
{
public function testClass()
{
userid = root.loaderInfo.parameters.userid;
}
}
}

Cool glad you found it ;-) And I promise I won't send you the link that says that using root is the "root of all evil" ;-)

[atnok]

I don't really understand what you mean? do i have to? thank you anyway for your help.

I was joking around..when I did a google search I came up on one entry that had an article saying that you should never use _root(now root it seems). It was just a joke.

Hi just trying to implement your code, and i can't get it to compile, surely the AS3 should be like this
package {

import flash.display.MovieClip;

public class testClass extends MovieClip {

public var userid:String;

public function testClass()
{
userid = root.loaderInfo.parameters.userid;
}
}
}

If written like this and compiled without error the userid var returns null, have I missed something?

Hi Sooty,

Did you ever get to the bottom of this? I'm grappling with the same problem right now.
Thanks
