hi :
I had a question about the proporite _xmouse(also for _ymouse)
the proporite of the scene is 800*600 in pixels
but the return valuer of _xmouse is not a integer valeur.(EX 139.58)
so i dont know why he can return a suck number with pixels.
if it's realy in pixels,it must return a integer number i think.and that's i
need.

yes, the value of _xmouse or _ymouse will not always be an integer value as it
returns the exact value of the mouse co-ordinates.

If you want the integer value you can round it off using Math.round(_xmouse);

Flash allows subpixel rendering and goes as far as twips (one twentieth
of a pixel). So, in fact, you can place objects on the screen at floats.
If you prefer integers, consider using the Math.round() method.
