when only setting _visible to flase., all other belongings are accessible,
all properties methods if it is forinstance subClass of MovieClip....
if on frame where the MovieClip is not present, nothing of its property is
accessible....
so big difference, visualy almost none, though

Subject: Re: [Flashcoders] What's different between _alpha=0 and _visible
=flase;
i have a related question
what is the difference between
- setting _visible = false on a clip
and
- structuring the flash movie so i go to a frame where that same
movieclip is removed.
see what i mean? i always have a pretty massice _root.content_mc with,
say, intro_mc, section1_mc, section2_mc inside it.
i always set _visible = false on all the clips i'm not currently
using, but it's sometimes tempting to have multiple frames in
_root.content_mc, one frame for intro_mc, one for section1_mc etc. to
save cpu.
does anyone know the difference between _visible = false and going to
a frame that hasn't got the clip.
ps. i have noticed how
intro_mc._y = - 2000
together with
intro_mc._visible = false
often gives better performance when showing for instance section1_mc.
but probably attachMovie and removeMovieClip is the best way to go at
this problem, in order to get the best performance?
thanks,
kalle

The other major difference is easily shown:
Place a movieClip on stage.
Give it an onRelease handler:
clip.onRelease=function(){trace("Release!");}
Test your movie - click on it, and Release! is traced.
Set clip._alpha to 0
Test the movie - click on where the clip should be, and Release! is
traced.
Set clip._visible=false
Test the movie - click on where the clip should be, and nothing
happens. The clip has effectively been removed from the drawing
heirarchy completely.
Cheers,
