I'm not sure of which angle you're wanting to end up (direction, origin,

degrees or radians, etc) but the basic algorithm for cartesian/polar

interconversion are in the Director technotes, with keyword "polar". (See

URL in sig.)


This is in old-style Lingo... hope it shows the principles, though.
