[Gnash-dev] a question

[Rake Xue]

Hi,
I've read the source of Gnash, but can't find the answer to a question.
And the question is that,
when the player goes back to a specific frame(use
gotoAndPlay,gotoAndStop, etc), then how does it decide to remove which
character and load which character? Cuz. the player has loaded a lot
characters by placeobject tag (generate by flash compiler) and
actionscript(as duplicateMovieClip(),attachMovie(),
createEmptyMovieClip(),etc), then goes back to a previous frame, how to
deal with these exist characters and how to place new characters, and if
remove the exist Sprite characters and they just have unload clipevent,
what's the sequence that the action codes will run by?

Thanks a lot.
