Hi Roman,
You describe my_var =null as being useless, but this should be enough for
the garbage collector to come along and reclaim an object?
With respect to the static issue, what do you mean with 'static instances' ?
Could u provide an example of such an object with isn't reclaimed?
Sorry, not at hand. I remember my first use of static values (NOT
instances, of course - excuse me if I said so, that's dumb of course)
with a gaming app, where I made a sokoban-style game within the whole
thing. This sokoban game was an instance of my sokoban-class, using
_some_ static values.
After the sokoban was over, the game mc has been removed
(removeMovieClip) and loaded anew when the player wanted to play another
round. The times after the first run gave me the headaches, until I
stopped using _any_ static value in my class.
Another weird example out of my actual project:
my_loader is an instance of my preloading-manager-class, the array
created_clips stores references to the successfully loaded mcs:
At some place - i.e. when stopping the game represented by the mc that
has been loaded by my "my_loader" - the game should be removed from
memory (for performance reasons):
my_loader.created_clips[names.game_1].undloadMovie();
my_loader.created_clips[names.game_1].removeMovieClip();
_root.host.debug("GameHost.gameStop(" + movie_name + "):
my_loader.created_clips["+names.game_1+"] ==
"+my_loader.created_clips[names.game_1]);
_root.host.debug("GameHost.gameStop(" + movie_name + "):
typeof(my_loader.created_clips["+names.game_1+"]) ==
"+typeof(my_loader.created_clips[names.game_1]));
The debug-call (simply directs text to a floating text field for
debugging) yields the following:
GameHost.gameStop(IcefallClimbing):
my_loader.created_clips[IcefallClimbing] ==
_level0.gamecontainer.IcefallClimbing
GameHost.gameStop(IcefallClimbing):
typeof(my_loader.created_clips[IcefallClimbing]) == movieclip
So you really should digest this: The loaded mc is first unloaded, then
removed, and still it sits there in memory as a moveclip! I'm seeing
ghosts....
When I - after unloding and removing -
delete my_loader.created_clips[names.game_1];
then of course my debug states it is "null", but I'm not really sure,
whether it really is null, or whether there simply isn't any variable
left that could point to my unloaded and then removed movieclip still
residing in memory...
Unfortunately I'm not really wondering whether it's a bug or a feature -
it's special, it's Flash.
Best regards,
Roman.
