I am working on a project that has a lot of limit bound
on. For instance, when a particular MovieClip - call it MC -
clicked, the initial rotation is recorded. Then a calculation
to determine the possible max delta rotations that can occur
or counter-clockwise) during the move. An onEnterFrame event
called and the MC is rotated and the _rotation is updated
until one of
the maxes has been reached.
What I would really like is a way to make the flash _rotation
the cartesian coordinate system, rotating counter-clockwise
and clockwise for negative rotation and starting with the
angle on the x axis going left to right.
If a translation method does not exist then a class that does
computation for finding delta angles and directional
between angles would be very helpful.
there's not much to do. _rotation in flash is the opposite of
rotation of standard plane geometry. you could just pass the angle
you want to rotate into a custom class or function and convert to
the opposite angle.
but if you do that, you may want to also convert y values and
change the top of the stage to correspond to Stage.height and
bottom of the stage to correspond to y = 0.
