To change your subscription options or search the
Try:
// movie_mc is the instance name of the movieClip
// you want to center on the mouse coords.
movie_mc._x = _xmouse - (movie_mc._width/2);
movie_mc._y = _ymouse - (movie_mc._height/2);
If the movieClip size doesn't change you can optimize this by
precalculating the (movie_mc._width/2) and
1) either double click your clip and group everthing and center it manually
OR
2) make sure your graphics inside that clip is at 0,0
and then
inside your MouseMove handler or onEnterFrame handler;
toCenterClip._x = _xmouse - (toCenterClip._width/2);
toCenterClip._y = _ymouse -
dont forget updateAfterEvent(); with the MouseMove use. it tells the player
to refresh visuals after the calculated mouse move event you catched even if
it wasn't time to render that frame.

MovieClip._width / 2 = its _x center
MovieClip._height / 2 = its _y center
hope it helps

In a test
where I ran a calculation a million times, shift right was about 200ms
faster than division.
Sorry, that's not a helpful metric. I should have said shift right
took ~90% as much time.

It depends where the registration point of your clip is. If it's at
top-left or centre, then the calculation is simple - see all the other
posts in the thread.
If it's unpredictable, use getBounds() - do something like this:
var bounds:Object=myClipToCentre.getBounds(this);
somewhere else, you'll need to change it or do other
calcualtions.

No prob. Incidentally, I'm pretty sure this is why BlurFilter, etc.
are optimized for blur amounts that are powers of 2.
