I don't think using coercion rather than a Math method will make a
noticeable difference in performance, really. But even though it's a bit
faster, the results won't be always correct if what you're looking for is
rounding (instead of just discarding decimals).
Also keep in mind that int() works

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???

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

try using Math.round() on your position values...

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
Make sure to always do Math.round to your x's and y's, so:
mc.x = Math.round(xPos);
mc.y = Math.round(yPos);
And make sure to do the same to all mc's contained within it.

For animation, if you're using something like Tweener that wont
