An easy way to do this is to build your movieClip so that the graphics
inside align in the upper left corner at (0, 0). Then take the width of
your movie and divide it in half. If you take this half-width value and
subtract it from your _xmouse then it should center your movieClip over
the mouse ho

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

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);
myClipToCentre._x=_xm
For an arbitrary registration point, use
var b:Object = mc.getBounds(mc._parent);
var offset:Object = {x:(mc._x - b.xMin, y:instance._y
- b.yMin)};
then
mc._x = (_root.xmouse - mc._width/2) - offset.x;
mc._y = (_root.ymouse - mc._height/2) - offset.y;

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.

MovieClip._width / 2 = its _x center

good people,
how do i move a moviClip to center itself at (_xmouse, _ymouse)...i
have the
onPress part down...i just need to center it on those coordinates
thanks

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.
