Math should be avoided when possible, I believe it is quit slow.
Maybe
Number >> 0 is even faster for rounding of ;)

int( ) is casting the content to integer, it has the effect to drop off
the decimal part. Same as Math.floor but lots faster

If the sprite.x is not an exact round number (so not an correct integer)
wouldn't that throw an error???

Casting to int is faster.
var tX:int = int(sprite.x)

Hi, Laurent,
You could use localToGlobal(), apply Math.round() to this global point,
compare the original global point with the rounded version, and then
offset
the child's coordineates by the differences.
Caveats are:
- if you do this multiple places in a display hierarchy, you'd need to
work
from the bottom upwards.
- during animation you're bound to introduce a certain amount of
jumpiness.

Hi,
Is there a way to be sure elements are positionned précisely on a
Pixel ?
I have a sprite containing sprites that are positionned on integer
coordinates so they are pixel positionned.
And this sprite is re-positionned when the window resize, so I used
int()
to be sure I got x and y as integers but still the content get blury
sometimes.
Is there something to do that flash always position element on a pixel
not
a pixel and half...?
thx
