Description
The floating-point _ yscale
property specifies the
height of mc
relative to its original
height, expressed as a percentage. If mc
is an instance, its “original height” is the height of
the instance’s symbol in the Library. If
mc
is a main movie, the “original
height” is the height of the movie at authoring time.
When the current height of mc
is the same
as its original height, _ yscale
is 100. A
_ yscale
of 200 doubles
mc
’s height relative to its original
height. A _ yscale
of 50 halves
mc
’s height relative to its original
height.
The _ yscale
property scales a clip about its
registration point (proportionately above and below the clip’s
registration point). To size a clip from above or below only, place
all of the clip’s content above or below the registration point
in the clip’s symbol (this is a useful technique for creating
vertical preloader bars). When a clip’s _ yscale
is set to a negative value, the clip is flipped
vertically as if across a horizontal mirror running through its
registration point (i.e., it becomes a vertical mirror image of
itself), after which the negative value is treated as a positive. To
flip a clip vertically without resizing it, set the clip’s
_ yscale
to -100.
Example
// Double the height of ball (the width remains unchanged) ball._yscale *= 2; // Flip ball vertically ball._yscale = -100;
