[Flashcoders] Loading Flash 6 .swf files into a Flash 7 .swf
I have a Flash application which loads in external .swf files for drawing
charts. My main .swf is compiled for the Flash 7 player, while the loaded .swf
files are compiled for the Flash 6 player. The Flash 6 .swf is not able to
access variables or functions which are defined in the _global context of the
Flash 7 .swf file. But if I have two Flash 7 movies, or two Flash 6 movies,
things work fine.
Is there some known interaction I should know about? Specifically, shouldn't
two .swf files compiled for different versions player still share the same
_global scope?
As an example, I've created flash6.fla and flash7.fla. They have the following
action script:
---flash7.fla---
_global.callbackFunction = function() { trace(Got Callback); }
loader_mc = _root.createEmptyMovieClip(loader_mc, 3);
loader_mc.loadMovie(flash6.swf);
---flash6.fla---
trace(Loaded Flash6.swf);
trace(_global.callbackFunction: + _global.callbackFunction);
---
The trace function shows me that _global.callbackFunction is defined if
flash6.fla is published for Flash 7 players. But if I republish, targeting the
Flash 6 player, the function is longer defined. It is like they have totally
separate _global scopes. If I switch from _global to _root, however, things
work fine. So, I can work around the issue. But it strikes me as real odd that
the two .swf files don't share the same _global variable space.
Clues?

Flash Player creates two different _global objects for swfs of different
versions.

RE: [Flashcoders] Loading Flash 6 .swf files into a Flash 7 .swf
_global scope is different, as well as any prototypes you've created.
However, it's not a security issue, simply a difference in how things were
implemented. So, you can get around it by simply making a reference in the
main SWF and re-referencing _global in the child SWF.
For example (in the main SWF):
_level0.global = _global;
Then in the child SWF:
_global = _level0.global;
Now the child _global references the main _global.
If you want a reference to the old child _global, you can specify (from
within the child SWF):
_level0._global;
Even though _level0 really is the main SWF, _level0._global when
referenced from the child SWF references the child SWFs original _global.
Strange but true.
