When the current width of mc is the same as its original width, _xscale is 100. An _xscale

of 200 doubles mc’s width relative to its original width. An _xscale of 50 halves mc’s width

relative to its original width.

The

_xscale property scales a clip proportionately on the right and left sides of its registra-

tion point. To size a clip from one side only, place all of the clip’s content on one side of

the registration point in the clip’s symbol (this is a useful technique for creating horizontal

preloader bars). When a clip’s

_xscale is set to a negative value, the clip is flipped horizon-

tally, as if across a vertical mirror running through its registration point (i.e., it becomes a

mirror image of itself), after which the negative value is treated as a positive. To flip a clip

horizontally without resizing it, set the clip’s

_xscale to –_xscale.

Example

// Double the width of ball_mc (the height remains unchanged)

ball_mc._xscale *= 2;

// Create a mirror image of ball_mc

ball_mc._xscale = –ball_mc._xscale;
