this code is part of a Component Window i 'm writing.
It 's a public method to move the object to a point, slowing down
(nothing new..)
My problem is that when lots of this function are fired the fps slow
down a lot. I tried to put the visibility off to found if it was the
code, and it is.
This functions it 's a bit strange because i need that the obj moves of
entires pixels (not 2.3 or 5.1) to avoid the blur of the rendering.
Doing so i must add just 1 pixel at time when the distance/fraction is
less than 1.
thank you in advance,
giorgio

var dx:Number = x - _parent._x;
var dy:Number = y - _parent._y;
var ax:Number = dx/fraction;
var ay:Number = dy/fraction;
if (Math.abs(ax) <1) {
if (ax >0) ax = 1;
if (ax <0) ax = -1
}
if (Math.abs(ay) <1) {
if (ay >0) ay = 1;
if (ay <0) ay = -1
}
var tx:Number = _parent._x + ax;
var ty:Number = _parent._y + ay;
var check:Number = 0;
if (Math.abs(dx) <=1) check++;
if (Math.abs(dy) <=1) check++;
if (check==2) {
_parent.move(x,y);
_parent.onSlideComplete();
this.removeMovieClip();
} else {
_parent.move(Math.round(tx), Math.round(ty));
}
}
}
