Re: [Flashcoders] getBounds AS3/AS2 issue (SOLVED)

[Ian Thomas]

Followup on this issue for the archives...

Eder Fortunato from Brazil suggested setting _lockroot=true on App C.
This solves the problem.

Re: [Flashcoders] getBounds AS3/AS2 issue

[Ian Thomas]

Further to this (again) I've investigated the whole thing in some
depth, and come up with this:

The bug affects the AS2 MovieClip.getBounds() and MovieClip.getRect() methods.

As far as I can tell, it only happens in this situation:

AppA is an _AS3_ application. AppA loads AppB.
AppB is an AS2 application. AppB loads AppC.
AppC is an AS2 application.

If you run AppA, then any getBounds() or getRect() calls on objects in
AppC fail, but they work as expected in AppB.

(If you just run AppB, then everything works as expected.)

I've tried various variants of this; if, instead of loading AppB, you
embed it into AppA at compile-time, the problem still occurs. It
appears to be something to do with loading one VM1 movie into another
one within a VM2 shell.

For the curious, here's a Zip containing a minimal test setup:
http://www.wildwinter.net/public/getBoundsBug.zip

All suggestions for workarounds welcomed, as this is a real nuisance
for what we're currently working on.

(For reference, this is in Flash Player 9,0,115,0, using either Flex
compiler 2.01 or Flex Compiler 3.0 for the AS3 and using Flash 8.0 or
MTASC for the AS2.)

Cheers,
   Ian

P.S. Fairly obviously, I will be reporting this to Adobe.

Sorry - to be clearer - using getRect() or getBounds() _on any object_
in c) returns undefined. If you write code in c) that calls getRect()
or getBounds() on b) e.g. _parent.getBounds(_parent) works fine.

Re: [Flashcoders] getBounds AS3/AS2 issue

[Ian Thomas]

Further to this, what looks like is happening is this:

There are 3 layers:

a) An AS3 App that instantiates/addChilds ->
b) An AS2 Shell _embedded_ within the AS3 App that loads ->
c) An AS2 .swf file.

a & b communicate using Grant Skinners SWFBridge, and have no problems
communicating.

Using MovieClip.getRect() or MovieClip.getBounds() within b) (or a, of
course) works fine.

Using MovieClip.getRect() or MovieClip.getBounds() within c) returns
undefined (at least, in my setup).

Running c) standalone, getRect() and getBounds() work fine.

All other code in c) and b) works fine.

At the moment it's looking like a player bug. Anyone got any other
ideas/things to test?

Cheers,
   Ian

No loading of images in involved here. I'm just trying to retrieve the

[Glen Pike]

Not sure if this applies to AS3, but in AS2, you had problems getting 
the width & height of loaded images & swfs until they were completely 
loaded.


The AS2 method was to implement the onLoadInit() function of the 
MovieClipLoader class and get info there.

Re: [Flashcoders] getBounds AS3/AS2 issue

[Ian Thomas]

Looking at it, it's MovieClip.getRect() too. How weird - must be some
sort of display parenting issue. I'll dig deeper and see what I can
find out; must be some sort of player bug.

Any and all ideas welcomed - I can't dream up a way to fake
getBounds() immediately (without some fancy blitting around of
Bitmaps, and that's much too heavyweight).

Cheers,
  Ian

[Flashcoders] getBounds AS3/AS2 issue

[Ian Thomas]

Has anyone got any idea why when I create an instance of an AVM1Movie
(embedded) within an AS3 app, AS2's MovieClip.getBounds() function
returns undefined within the contained movie whereas it works
perfectly well if the AS2 movie is run outside the AS3 app?

Same result with Flex2.01 and Flex3 compilers.

Cheers,
   Ian
